Abstract:

The development, construction and operation of a wind farm is a complex and long process involving many different agents. Disputes arising from interpretations of contract clauses are usually lengthy and costly. Unprecise definition of boundaries (both physical as well as contractual) is also a source for delays and extra costs. On the other hand, blockchain technology provides the framework under which a set of data can be irrevocably and undisputably arranged in a way that all parties can share it and add elements to the blockchain in a secure way which is validated by the system itself. One of the uses of blockchain is the implementation of smart contracts witch enable the execution of certain clauses without the need of a third party external assessment. Some of the contracts are exceedingly complex to try to reduce them to a set of simple rules, but the development of smart contracts for specific aspects can be of great help to increase the efficiency of a project. In this paper, we analyse the different phases of a wind farm project (from predevelopment works to operation and maintenance) and suggest smart contracts for those elements that can be singled out as suitable for this technology. We find that, at some stages, a formal input from a third party may be needed and suggests ways to automatize this. This hybrid character is not present, however, for the operation of the wind farm, where a sensible choice of sensors may confirm a fully automated system.

Byeong Hee Chang has graduated from Korea Advanced Institute of Science and Technology (KAIST) in 1996 with PhD and worked in Korea Aerospace Reseach Institute (KARI). In KARI, he woked in wind tunnel design, construciton, and wind tunnel tests. Since 2016, he has been interested in this measurement technique with a roll-rotating ultrasonic anemometer for measuring wind speed and direction. In 2017, he did a validaton research with wind tunnel tests.

Abstract:

Generally, wind turbine anemometers are installed on the nacelle behind wind turbine. So, they are in the wind turbine wake flow and the measured wind speed and direction are influenced by the wake and different from the freestream’s. Recently, the ROMO Wind developed a spinner anemometer of 3 single-axis ultrasonic sensors installed on the spinner for measuring undistured wind speed and direction. In this study, it was checked if a 3-axis ultrasonic anemometer could replace the 3 single-axis ultrasonic sensors as a spinner anemometer. The technique is based on the coordinate transform from the rotating sensor axis to the fixed coordinate for measuring wind speed and direction. Its validation tests were done with a roll-rotating test stand in the Korea Aerospace Reseach Institute (KARI) Low Speed Wind Tunnel. Even after the coordinate tranform, small rotating effect still remains in wind speed and direction. But, after one revolution of wind turbine, its mean values were converged to the test values within certain limits. The mean values were not much afftected by RPM (revolutions per minute), but affected by yaw angle and wind speed. The less yaw angle, the errors decrease. Upto 20° yaw angle, the errors of the mean values from the test values were less than double of the sensor own accuracy. At 10° yaw angle, the mean value errors were 2.0% RMS (root mean square) in wind speed and 1.7° in wind direction. But, in high yaw angle such as 60° or above, the mean value errors were drastically increased. So, in real application, if initial yaw angle is too large for this measuring technique, it could be reduced with a conventional nacell anemometer to within 20° and then it could be aligned more preciously with this technique including 3-axis ultrasonic anemometer installed on the spinner. This concept will be applied and checked to some operating wind turbines in real field in near future.

Abstract:

This work aims with the effect of combined electro-thermal stresses under dark and illuminated conditions on electric and working parameters of silicon based photovoltaic cells measured after various conditions of stresses. In practice these combined stresses could lead to final degradation of solar cells and modules with creation of hot spots. In our study, a digital double exponential model of the PV cell was used to analyze experimental measurements. An inverse current and/or temperature for different stress levels simulate the effect that can occur under normal working conditions as the result of shading. The changes in PV efficiency and parameters of PV cells and modules exposed to shadow effects compared to that in normal working mode are discussed based on experimental characterizations done in the present study.

Abstract:

Sources of energy which are used on large scale are termed as conventional sources of energy where as the energy sources which are used on small scale are called as non-conventional sources of energy. Green energy produced from non-conventional sources include small hydro power, wind power, solar energy, geothermal and energy produced from biofuel. Increase in land and air pollution during the conversion of energy sources of fossil fuel such as oil, coal and natural gas have their adverse effects on environment and ecology. Depleting quality of these sources raise the question of sustainability in the long run thereby compelled humanity to go in search of the other alternatives. In this context, the non conventional sources of energy have attracted the global attentions and evoked interest among policy makers as a viable option for sustainable development. Out of 120 crore population of India, 46% of them live in rural and far flange areas and survive on kerosene, wood for fire and cooking or nonconventional sources of energy as their primary sources. It is hurting to know that India loses nearly dollars 18 billion annually in power sector which is sufficient to provide 490 million free of electricity for a year through micro greed. As the world moves to cleaner energy sources and water becomes increasingly valuable commodity in many regions, it will influence the choice of energy options. Electricity production accounts for more than 50% global warming emission with the majority generated by coal fired power plants in the world. Natural gas power plants produce more than 10% total emission in the world. In contrast to this most renewable energy and nonconventional sources produce very little global warming effects. In these article efforts has been made to project the overall scenario of non conventional sources of energy and their utility in remote areas where conventional energy cannot reach. The energy produced by small hydro, solar and wind etc can find its place to cater to the needs of people living in rural areas. The article also refers the research and innovative measures required to be under taken to supply power to the masses in rural areas and it also highlights the challenges faced to supply energy to far flanged areas.

Abstract:

Predicting and enhancing the life-cycle of lithium-ion battery packs has been the subject of studies towards the large-scale use of storage systems to store electrical energy during fluctuations and unpredictable behaviour of wind renewable. Battery pack is a group of cells which are placed in a parallel, series or matrix form to provide the required power. Life cycle prediction of a single cell is challenging due to the complexity of electrochemical reactions, thermal variability and the formation of SEI (solid electrolyte interphase) layers. Cell interconnections make the prediction more challenging as the electrical dynamics and thermal characteristics of each cell is different from the others. This work introduces random variability where the aging of a single cell propagates and reduces the life of the whole pack. The use of accurate electro-chemical modelling and wireless sensor/antenna system in real-time estimation of the critical cell parameters, i.e. state-of-the-charge (SOH), state-of-health (SoH), internal resistance, and temperature variation are investigated. The integrated system will significantly suppress the aging propagation and enhance the life-time of the pack.

Abstract:

Over the past few years, the University of Applied Sciences in Saarbrücken (htw saar) has carried out intensive research into small scale wind turbines, known as vertical axis wind turbine (VAWT). The well-known problem with the design of these types is that they did not start to run automatically. The VAWT must be electrically driven to start, which is due to design problems. The reason was identified by our team with numerical simulations of detachment behaviour at the blades. However, this can only be clarified by means of detailed measurement. In order to compare simulations, and investigate turbines behaviour more deeply, a new wind tunnel was constructed from scratch at htw saar. The so- called Göttinger design was chosen as type of construction, which means that air circulates inside. Dimensions of the tunnel are 12 m x 3.5 m x 2 m. Air is driven by a 7 kW rotor placed on upper side. Its nozzle diameter is about 1.6 x 1.6 meter. The VAWT can be placed in this position. Access points are positioned for temperature, pressure and velocity flow examinations. An additional heat absorber is used to control the air temperature. Two windows positioned inside the nozzle chamber can be used to visualize turbulence effects and enable the qualitative measurement of the spatial position and strength of compressible air vortices with a high-speed camera. There is currently no alternative test rig know for these kind of experiments. Thus, qualitative and quantitative behaviour of the VAWT can be examined. The investigation in the transonic wind tunnel, as well as the adjustment with simulations of the VAWT will be used for validation and further design development.

Abstract:

Synchronous belt is commonly used in the pitch system for wind turbines. It is a flexible pitch method and has a lot of advantages compared with hydraulic pitch system. Engineering methods is usually used to calculate the strength of synchronous belt, this is also the usual method in other industry. The disadvantage of this engineering method is that a lot of bearing capacity of the belt is wasted due to the large safety margin required by the methods. To fully utilize the capacity of synchronous belt, a more accuracy FEA (finite element analysis) method is developed to evaluate the strength of synchronous belt and estimate the remaining life time of belt on specific site conditions. This method could also be used in other industries with heavy and alternating loads.

Abstract:

Wearable technologies are driving current research efforts to self-powered electronics for which novel high-performance materials such as graphene and low-cost fabrication processes are highly sought. We demonstrate the integration of high-quality graphene films obtained from scalable water processing approaches in emerging applications for flexible and wearable electronics. We developed a novel method for the assembly of shear exfoliated graphene in water, comprising a direct treansfer process assisted by isopropyl alcohol evaporation. We demonstrate that graphene films can be easily transferred to any target substrate such as paper, flexible polymeric sheets and fibres, glass and Si substrates. By combining graphene as electrode and polydimethlysiloxane as active layer we demonstrate for the first time a flexible and transparent triboelectric nanogeneragor for haversting energy. Our results constitute a new step towards the realization of energy harvesting devices that could be integrated with a wide range of wearable and flexible technologies and opens new possibilities for the use of triboelectric nanogenerators in many applications such as electronic skin and wearable electronics.

Abstract:

Energy (or Desert) towers are a renewable energy producing device suitable for hot and dry climates. They are based on spraying sea water from the top of a tower 500 m high. The sprayed droplets evaporate and thus cool the surrounding air creating a downdraft which moves electricity-generating turbines located at the basis of the tower. The air is subsequently delivered through a diffuser to the surrounding environment where the salt containing water precipitate to the ground. The Energy tower generates electricity without producing greenhouse gasses. It has been estimated that approximately 1/3rd of the gross power delivered by the turbines is necessary for pumping the sea water to the tower site and up the tower, whereas another 2/9th is lost to aerodynamic friction, leaving 4/9th as net power. The electricity is generated 24 hours a day (although at a much smaller power during the night) CFD calculations indicate that an energy tower with a 200 m diameter and a 600 m height may deliver a 250 MWe net electrical power and 250 GWh a year. In addition a by-product is desalinated water that can be derived from the cold humid air. The estimated cost of the generated electricity is estimated to 2-3 cents/kWh – which makes it competitive and clean, without green-house gasses. The major environmental effect is the precipitation of salt. Energy towers are suited for latitudes between 20 and 30° which are usually hot and dry.

Abstract:

The dramatic growth of energy world consumption and the evolving sustainability awareness and demand, go ‘hand in hand’ and already have considerable impact on world politics and it’s economics. Wind turbine farms strive ever higher, consume ever larger space, with more complex and costlier logistics for their delivery, erection, maintenance and ‘energy crop’ distribution. This paper reports about research and development results concerning a new design- implementation paradigm of Wind and Renewable Energy Harvesting Complex, situated in the Marine Environment on floating mega-platforms. The essence of the new approach may be summarized as follows: 1. compact (wing to wing) wind turbine arrangement on floating mega-platforms, capable of auto-rotating into the wind, with 30÷60 turbines, each. 2. the platform will support additional wave-turbine rows, solar panels, sea-current activated turbines and marine bio-energy farm. 3. the whole complex facility is produced –constructed-assembled in a coastal industrial fabrication plant and sea-transported-towed and moored in its site of function. 4. the platform, a semi –submersible mega-structure array, will be solved to support all energy storage, guide instrumentation, maintenance and energy crop handling. 5. agglomeration of 4÷6 energy generating platforms, when combined, will constitute massive marine power station. 6. the compact, multi-modal, marine renewable ‘blue energy’ power station is solved for stage-completion, rearrangement and relocation, if and when desired. In conclusion: all logistics of the power station, namely: construction, erection, transportation, mooring-anchorage, maintenance, supervision, energy harvesting and its delivery, are highly industrialized, thus raising dramatically its cost-effectiveness and economic attraction.

Abstract:

Coal is the major energy source in China. The release of Cr, Pb, V and Zn during coal mining and utilization is considered to have prominent environmental impacts. Soil samples were collected from four representative coal mines of Huaibei (BS, RL, ZXZ and WG). The study aims to investigate the accumulation, transfer behavior and potential sources of Cr, Pb, V and Zn. The concentration of Cr, Pb, V and Zn was analyzed using ICP-MS, and sequential extraction procedure was used to find the four chemical forms. The mean concentration of Pb (22 μg/g) and V (78 μg/g) in soil samples was lower than the global soil background, while the mean concentration of Cr (82 μg/g) and Zn (72 μg/g) was higher than the global soil background. The concentrations of Pb, V and Zn were high in the oldest coal mine (BS), while Cr was high in the youngest coal mine (WG). The concentration of Cr from BS coal mine and Pb from RL coal mine decreased with increasing distance from the coal gangue. The concentration of V from BS and RL coal mine increased first and then decreased with increasing distance. Chromium, Pb and V were observed in the residual form, while Zn was observed to be in reducible form. The potential ecological risk assessment method showed that Cr, Pb, V and Zn contamination level near the coal gangue was very low.

Abstract:

This paper covers definition of local, meso and large-scale factors and climate changing role on wind and solar energy potential. Hourly and daily wind speed and solar radiation data define monthly and seasonal variations of wind and solar energy potential. The main aim of the paper is to define wind and solar energy potential variations at two study areas in Istanbul, (Asian Side: Kandilli and European Side: Maslak). Wind speed, solar radiation data cover the interval of 1911-2017. The paper presents some results on descriptive statistics, Wavelet applications, Speedy Model estimates and ANN (Artificial Neural Networks) simulations. Wind data makes use of the Weibull Distribution Function as a tool to represent the frequency distribution of wind speed. Solar energy potential analyses based on Wavelet shows the role of small, meso and large-scale factors on energy potential variations. Extreme winds are associated with large-scale events with periodicities between 5-20 hrs, 5-30 hrs, 30-45 hrs or 20-60 hrs in winter. Small scale and meso scale factors is associated with lower wind speed with periodicities changing up to 35 hrs. A Speedy Model approach was applied when estimating wind – solar energy potential at the site was assessed using a historical data for every 30 year period. As a conclusion available wind speed and solar radiation by using Speedy Model and ANN simulation approach realistic estimate of energy potential. This paper is dedicated to researching the potential wind-solar energy production in Istanbul. They show the role of climate changing on energy policy.

Abstract:

Most countries in the world especially those in Asia and Africa despite undertaking policies meant to help meet Sustainable Development Goal 7, there are still a sizable number of households who have not yet fully embraced energy saving technologies. This study provides highlights on the economic and environmental benefits for investing in energy saving light-bulbs. Using a survey and a multistage random sampling approach, we administered questionnaires to 1,650 households in Ghana. The relevant diagnostic tests associated with cross-sectional data were undertaken. We estimated a maximum-likelihood probit model with its associated marginal effects to find out how choice is influenced by environmental consciousness and other demographic factors. Our results are consistent with economic theory as well as what earlier empirical evidence found in literature. That is, environmental consciousness (both local knowledge and global knowledge), education, income etc. are very important in explaining the choice of buying energy saving light-bulbs in Ghana. Besides advocating for information that will make society more environmentally conscious, we further recommend the use of fiscal policies (i.e. subsidies) to support lower income brackets who are predominant in developing countries.

Abstract:

The distribution of 16 priority polycyclic aromatic hydrocarbons (PAHs) in water, sediment and soil samples from the middle reach of Huai River were analyzed by a gas chromatograph-mass spectrometer (GC-MS). The total concentration of Σ16PAHs ranged from 783.83 to 1475 ng/L in water, 552.48 to 1199.57 ng/g dw. (dry weight) in sediment, and from 498.85 to 1322.83 ng/g dw. in soil. The spatial distributions of Σ16PAHs revealed that PAHs contamination in water, sediment, and soil from the middle reach of Huai River were at the midpoint of the global ranges. Along the vertical profiles of water column, higher Σ16PAHs levels were seen in surface and bottom layers. The PAHs distribution in each depth of water column is found to be controlled by organic carbon, but the correlations between PAHs and organic carbon were not observed in sediment and soil. We observed that no correlations existed between particulate-water partition coefficient (Kow) and organic carbon between water and sediment system. The principal component analysis suggests that coal combustion and refined petroleum products combustion were the primary PAHs contributors in the studied water, sediment, and soil. The risk assessment of PAHs indicated that PAHs contamination in sediment-soil system might list as middle levels, but high ecological risk of PAHs in water column.

Abstract:

Recently there has been an increasing interest in concrete towers for wind turbines primarily due to the fact that there is a larger demand for bigger wind turbines and higher towers, resulting in larger base diameters for these towers. Production of such towers in steel is complicated and expensive and so is transportation and erection of the towers on site. Instead smaller segments of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) can be transported to the site by trucks and assembled on site. UHPFRC is characterized by high and compressive strength combined with an extreme high fracture energy makes it possible to make wind turbine towers of heights of over 200 m. The two main concerns are the eigenfrequencies of the tower and the fatigue resistance. This study is on the dynamic behavior of an 31.2 m high experimental UHPFRC post-tensioned wind turbine tower. The dynamic stiffness of the whole system and the soil-foundation-structure interaction is determined using Operational Modal Analysis (OMA). In addition a series of low-cycle fatigue experiments have been performed. Experiments on beams in three point bending have been performed in a newly developed test set-up. Both static and fatigue loading were carried out. Due to the high fatigue resistance of the material, focus has been on low cycle fatigue. In the tests, it is seen that the descending branch of the static experiments can be correlated to the fatigue life, indicating static tests can be used for quality control of the fatigue life.

Abstract:

In recent years, the increasing penetration of Renewable Energy Systems (RESs) has made an impact on the operation of the electric power systems. In the grid integration of RESs, data acquisition systems and communications infrastructure are crucial technologies to maintain system economic efficiency and reliability. Since most of these generators are relatively small, dedicated communications investments for every generator are capital cost prohibitive. Combining real-time attack-resilient communications middleware with Internet of Things (IoTs) technologies allows for the use of existing infrastructure. In this talk, I will present our work in developing an intelligent communication middleware that utilizes the Quality of Experience (QoE) metrics to complement the conventional Quality of Service (QoS) evaluation. Furthermore, our middleware employs deep learning techniques to detect and defend against congestion attacks.

Abstract:

Absorption coefficient of emission gases of carbon dioxide responsible for temperature in the troposphere layer, which is less than the altitude of 10 km in the atmosphere, is presented in this work. It has been well known that the solar irradiation within short wavelength range near the visible range can be absorbed, scattered and transmitted by the atmosphere and absorbed and reflected by the earth ground. The ground emits radiation in the ranges of long wavelengths. In the presence of carbon dioxide and other emission gases, the atmosphere acting as the glass of a greenhouse increases temperature of the atmosphere. Even though global warming strongly affects the life of the human being, the cause of global warming is still controversial. This work thus establishes a fundamental, systematical and quantitative analysis of absorption coefficient of carbon dioxide in the troposphere layer. Absorptions of carbon dioxide are considered in bands centered at 15, 10.4, 9.4, 4.3, 2.7 and 2 micro meters.

Abstract:

Photovoltaic energy is one of the most disseminated green energy sources. Its operation is based on the photovoltaic effect that takes place in photovoltaic cells, which are arranged in regular formations giving place to photovoltaic panels or modules (the commercial elements that can be acquired in a normal way). The performance of the photovoltaic panels is subject to ambient conditions as temperature and irradiance, and can be predicted using the datasheets provided by the manufacturing companies. The problem is that those parameters are generic and not adapted to a specific device. In this plenary talk the practical problem of designing an empirical and data-based model of photovoltaic panels will be addressed in a generic fashion. Besides, an instance of the faced problem will be posed and solved using a commercial photovoltaic panel, more specifically a Mitsubishi PV-TD1185MF5 device placed at the Faculty of Engineering of Vitoria-Gasteiz (University of the Basque Country, UPV/EHU, Spain).

Abstract:

The use of renewable energy sources is expressive in Brazil. The main categories are hydropower, biomass from sugarcane, firewood and charcoal. Firewood and charcoal are produced from eucalyptus forestry and represent 8.0% of gross domestic supply. The production of forest biomass has a great potential to increase in Brazil, due to land availability and high productivity of forest. However, there are still many challenges to the advance of forest biomass use for energy purposes. Therefore, the aim to present this study was to characterize three production systems of eucalyptus most typically used in Brazil, focusing on an analysis of the potential and the challenges for energy use. In two cases, this study analyzed the production chain of firewood, both for agricultural and industrial use. In the third case, the forest production for charcoal produce was considered. The research strategy involved data collection through visits and interviews with different agents that represent the productive chain. The results present that the chain segments characterization: inputs, forestry production, harvest and transport of firewood, and consumers. Costs and financial viability indicators for eucalyptus cultivation for firewood production are considered. Based on the results, potential and challenges are discussed.

Abstract:

Session Description: With the constant changing policies coming out of Washington, a desire for more power from renewable energies and having the funding to pay for it are no longer the only battles that needs to be fought. Constructing a large scale renewable energy power plant is now only as good as the team that works behind the scenes to make sure the project is in compliance with the constant and fast changing Federal, State, and local regulations. As corporations look toward renewables for their energy requirements, through a success story in Maryland, I will discuss helping make that possible by not only including what it takes to bring large scale renewable energy onto the grid, but all the required non-construction work that must take place to approve a power plant. Specifically, I will dive "in the weeds" and outline the technical requirements to achieve large-scale power, the regulatory work required prior to construction, the compliance work required before, during, and after construction, as well as the legal side of making a large-scale power plant possible. I have experience building solar facilities, as well as providing expertise in both regulatory frameworks around renewable energy and environmental compliance that must coincide with renewable energy projects. I also have general legal knowledge in environmental compliance and regulations.

Nicolai Rémy is in the final year of PhD at the Corsican’s University on the integration and optimization of methanation reactors. Its objective is to help implement biomass recovery techniques in Corsica. Part of his research time is dedicated to assisting regional and departmental agricultural chambers as scientific advisers.

Abstract:

The University of Corsica Pasquale Paoli contributes to research on the efficiency and integration of renewable energy, which include biomass waste recovery’s studies. Two types of substrates have been selected to initiate researches about their methanogenic power: green wastes from clearing and; stillages, which are drying residues obtained after the aromatic plants hydrodistillation for the production of essential oils. The first study allowed characterization of the chemical composition and methanogenic power of the plants used: arbutus (Arbutus unedo), laurel (Laurus nobilis), Cistus from Montpellier (Cistus monspeliensis) and stillage of immortelle (Helichrysum italicum). The organic matter splitting has been carried out according to the Van Soest protocol, while the methanogenic potential was taken directly to the pilot reactor which has a capacity of 15 liters. The Cistus and immortelle spent grains have the higher methanogenic potential, 231±9 and 207±16 Nm³ Biogas.tMV^-1 respectively. Both substrates has an holocellulose ratio with a high level of lignine: 3.8 for the Cistus and 3.4 for the immortelle stillage. The two other plant species have the lowest methanogenic potential: 101±7 Nm³ Biogas.tMV^-1 for the arbutus and 118±4 Nm³ Biogas.tMV^-1 for the laurel, with respectively lowest ratios (1.67 and 2.43). The same ranking is established between the biogas amount produced and the holocellulose/lignine values. By ascending order: the arbutus, the laurel, the immortelle and the Cistus. The result seems confirmed the correlation between production and holocellulose/lignine ratio.

Abstract:

In this study, a generator prototype has been designed to gain electricity energy from solar heat with using the thermoelectric modules. With the prototype high amount of heat obtained from solar heat was converted to electrical energy by means of a simple system. This prototype was tested for use in the irrigation system. With the designed generator which is using 20 thermoelectric modules  where the temperature difference between the TEG surfaces is 32.8°C the short circuit current (R_L=0) was measured as 1.42 A. When the R_L is equal to 15 ohm (R_L=15 Ω), the TEG voltage was measured 8.1 V which was 13.87 V before no load and passing current over load was measured as 1.1 A. In this case, 8.91 W powers were transferred over the load. The produced power was decreased with less and more values of 15 Ω. By disabling the private water circulator system DC circulator pump was connected to the output of TEG. When T_H is equal to 94°C (T_H=94°C) the T_C was measured as 61°C (T_C=61°C) and the pump was worked with the power of generated by TEG itself.

Y G Keneni has completed his MSc from Addis Ababa University, Faculty of Science, Ethiopia. He is the Academic Staff of Hawassa University and doing his PhD at the Norwegian University of Life Sciences, Faculty of Science and Technology, in the area of Biodiesel. He is working on jatropha (Jatropha curcas L.) seed drying processes, mathematical modeling of the drying kinetics, extraction of oil from jatropha seeds by different solvents as well as simultaneous transesterification reactions of the oil in the presence of heterogonous catalysts to produce biodiesel.

Abstract:

Jatropha (Jatropha curcas L.) seeds contain non-edible oil and have been considered as a promising biodiesel feedstock. The present research emphasized on the drying kinetics of jatropha seeds at storage moisture content and the mathematical modelling of the drying process. The non- pretreated seeds (whole seeds) and pretreated seeds (crushed seeds) were dried at five different air temperatures (313, 323, 333, 343 and 353K) in a standard heating furnace. The moisture loss from the seed samples was systematically recorded, converted to unit less moisture ratio and adjusted to four frequently used semi-theoretical mathematical models: Lewis model, Henderson and Pabis model, Page model and Avhad and Marchetti model. The fitness of the models to the experimental data were compared using the coefficient of determination, chi-square test, root mean square error, mean bias error and mean absolute error. It was found that the increase in the air temperature caused a reduction in the drying time of both the whole and crushed seeds. From the four mathematical models, Avhad and Marchetti model was found to be the most suitable to represent the drying kinetics of jatropha seeds at the storage moisture content.

He has been majoring Electrical Engineering at Seoul National University of Technology and joined Chungnam National University for more than two years in various capacities, primarily within the area of Mechanical Engineering.

Abstract:

 Proton exchange membrane fuel cell (PEMFC) is well known as the typical renewable energy with the eco-friendly characteristics because the emission is only water. Especially, it is well applied for fuel cell vehicle (FCV), because the operating temperature is low, and energy efficiency is high. Some stack durability problems, however, have been raised to ensure the long life of stack. Therefore, the durability of stack needs to be thoroughly researched to improve the life of stack. It is known that the performance and the durability of fuel cell stack is affected by the many kinds of durability degradation factors. Above all, operating temperature is evaluated as the main factor that significantly influences the durability of stack. The experimental study on fuel cell life with operating temperature, which is conducted under constant current condition has been developed by many academic world. However, it does not reflect the vehicle driving environment that load changes continuously. Changing the vehicle load means that the current density of stack is also changed, and the operating temperature of stack is affected by the heat generated from chemical reaction, and the cooling system. JRC report by EU depicts the experiment methodology using unit cell stack, and made the vehicle driving cycle reflecting the urban driving cycle and extra urban driving cycle. In this study, the three cell stack experiments employing the EU New European Driving Cycle (NEDC) under 55℃, 65℃, 75℃ temperature conditions were conducted for respectively 300 hours to evaluate the effects of operating temperature on the stack durability degradation. Polarization curves were obtained every 100 hours, and each curve was compared with others. Then, the electrodes were observed by the scanning electron microscope (SEM). The voltage degradation rate at 75℃ condition was higher than the results from other condition tests. As the result, it was concluded that the higher temperature is, the higher voltage degradation rate is.

Abstract:

Earth is a tricky place to live. We humans exist in a tiny sliver of perfect conditions for even existing. 200 feet above or 200 feet below, you’ll find it impossible to survive as the conditions are not suitable for human life without extremely good protections.  There is no dispute between climatologists about warm temperatures trapped low enough in the earth’s atmosphere to affect the polar ice caps in dramatic fashion.  NASA recently released a time-lapse video of warm air circling above the Arctic ring. In it one cannot help but believe that they are watching a sick Mother Earth inhale and exhale as each season shows ice cap growth and shrinkage. What’s become clearer now more than ever is that even as relatively non-educated climate observers, we can easily see that the earth’s temperatures are warming drastically and that sea levels are rising.

When Florida Governor Rick Scott decided to decree that no state government agency would be allowed to use “climate change” in any officially submitted document context, people had no choice in local government but to obey.  Little did Florida residents know during the 2004 hurricane aftermath a plan for dismantling environmental science agencies would be rolled out with a future GOP President. Nor would they suspect, despite Florida’s unique vulnerabilities, that Scott would be first to show DC the way to true climate change denial. Now we are in the pre-hurricane season days of 2018 with only a few short weeks to prepare and as usual city governments are lagging far behind across the state. It’s not all the fault of state leaders that the counties and municipalities have fallen behind with innovative infrastructure or community action plans.  Florida’s local leaders would have a say in how their tax revenue projects could be implemented.  Political midterms season and a windfall of federal relief dollars to the tune of $7 million has St. Augustine city government finally active in planning how to catch- up fast.  This makes the city vulnerable too. Ignoring the reality of climate change is going to cost the whole of humanity in a very near future.  We must act with certain knowledge and a realistic view to solve the crises we as citizens and leaders, especially mayors, face.

Abstract:

The energy reforms that have been developed in recent years in several countries as Mexico, have allowed the installation of renewable energy in the buildings of end users. However, this measure has not been enough to stop the climate change because the energy consumption is still increasing. Therefore, it is necessary to raise awareness and empower the end user about renewable generation and the efficient use of energy. This work proposes an energy management model through a virtual microgrid based on real-time monitoring of energy consumption and photovoltaic generation. Thus, the University Center of Tonalá, which is one of the 16 campuses of the University of Guadalajara, as part of the Integral University Program of Energy Transition has installed a first photovoltaic solar farm of 499 KWp, and through the Institute of Renewable Energies is developing a project for energy monitoring in real time of all its buildings, with the installation of more than 200 current sensors. With this approach, the university community is involved to evaluate their energy indexes and have an active control of their demand that allows them to make decisions about the energy management of each area, so that users are active clients of the microgrid , seeking to maximize virtual gains, which can be reflected in some kind of profits. This proposal can be replicated in other university centers and in public buildings that generate their own electricity.

Abstract:

The projections of the horizontal solar radiation (Gh) derived from the empirical method based on the temperature range across Nigeria, for photovoltaic (PV) resource potential by the end of 21^st century, has been investigated. Observational monthly maximum and minimum temperature data from the Climate Research Unit (CRU) has been validated by comparison with the Nigeria Meteorological Agency (NIMET) in the 3 representative sites of Gh Zones I, II and III respectively whereas the CRU estimated monthly and annual mean Gh has been validated by comparison with the European Commission - Joint Research Centre - Photovoltaic Geographical Information System (PVGIS) data across the country. Selected Coupled Model Intercomparison Project’s 5^th phase (CMIP5) and Coordinated Regional Downscaling Experiment (CORDEX)-Africa models performances in representing the estimated Gh has been examined. The models’ outputs project varying Gh outlooks for each location whereas the identified epochs in the estimated annual mean Gh show more locations having potential significant trends from 2039 to 2098 than from 2006 to 2038 in both the RCP 4.5 and RCP 8.5 outputs respectively. The results are vital tools in PV resources planning, siting and management across the country.

Abstract:

In recent years, area of renewable energy is gaining importance due to challenges associated with non-renewability of fossil fuels. Lignocellulosic biomass provides an alternative source for green and renewable energy. 5-Hydroxymethyl furfural which is the most important intermediate derived from lignocellulosic biomass is gaining importance because of its potential in various industrial applications. Efficient conversion of biomass can be directly processed via hydrolysis process under milder reaction conditions using solid acid catalyst. In the present work, three different kinds of modified activated carbon (catalysts) i.e. H₂SO₄-AC_, H₃PO₄-AC and HCl-AC were synthsized in order to investigate the effect on the yield of 5-HMF via degradation of cellulose in [C₄mim] Cl. Characterization studies were performed to examine some changes in morphology and functional groups of the activated carbon through SEM and FTIR including BET surface area of before and after modification of activated carbon. Results showed that all the three modified catalysts were promising and showed appreciable catalytic activity with the maximum yield in 60 min. The percentage yield was 36.33±0.24% using H₂SO₄-AC, 32.27±0.3% using HCl-AC and 33.03±0.99% using H₃PO₄-AC as catalysts respectively. These appreciable yields obtained by chemically modified activated carbon using [Bmim] Cl as green solvent may be due to the presence of C₂ hydrogen of imidazolium ion which is acidic in nature and hence may promote the reaction at faster rate. On the other hand, imidazolium molecule helps to stabilize the end products through hydrogen bonding interaction. In addition, effect of several metal ions on modified activated carbon was studied after impregnation of metals including Cr⁺³, Al⁺³, Cu⁺², Zn⁺², K⁺ and Fe⁺³ on the hydrolysis of cellulose using H₂SO₄-AC as catalyst under same conditions. The catalysis effect of Cr³⁺ exhibited significant effect on accelerating the hydrolysis rate and improving the yield of 5-HMF as compared to other metal ions. The yield was increased to 49.02±0.98% for Cr³⁺ metal ion respectively at 120°C with the reaction time of 1 hr. Also, the recovery of sugars and ionic liquid from the catalysis system makes the process economically feasible at large scale. Catalyst recyclability was also studied and it was observed that catalyst was reusable for 3 runs with minimal loss in activity. In addition, ionic liquid was recovered by using appropriate amount of salt solution. These modified and immobilised solid acid catalyst with ionic liquid as green solvent proved to be promising to facilitate cost effective and eco-friendly conversion of cellulose to value added products.

Abstract:

As the worldwide demand for energy grows, various studies in the field of energy efficiency are stimulated, and one of them is certainly the use of renewable energy. Sub-Saharan African continent is lacking globally in terms of   hydropower development as well as other renewables. Africa is endowed with a huge untapped renewable energy potential jet most of these potential sites are not yet developed. The rural communities within the region have been deprived of electricity for so many years now with even those in the urban centers experiencing a lot of power cut off. Renewable energies (RE) represent a foundation to steer the energy system in the direction of sustainability and supply security. The importance of renewable energy generation for sustainable power based on its capacity to provide electricity to the rural communities along with contributing to the national grid towards alleviating the serious shortage of electricity within the sub-Saharan African continent and ensuring sustainability of renewable energies especially small hydropower. The paper describes various problems faced during renewable energy generation and the approaches used to resolve the problems. The paper also seeks to bring out the current status and future prospects of renewable energy in sub-Saharan Africa together with recognizing the difficulties confronting full scale of its development. Conclusion was drawn on the role of the governments on the renewable energy development in the continent.
