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.

Abdullah Hakan Yavuz has completed his PhD from Gazi University. He is currently working as an Assistant Professor in Electrical and Electronics Engineering Department at GaziosmanpaÅŸa University. He has published more than 15 papers in reputed journals.

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.

Jaesu Han is a MS candidate in Mechanical Engineering at Chungnam National University, being currently responsible for “Dynamic modeling of fuel cell system for analysis of system durability” project. 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.
