David Wright combines an Engineering PhD from Cambridge University, UK, with his current position as Full Professor at the University of Ottawa's Telfer School of Management to provide a business perspective on solar power. His present work evaluates capital cost trends for solar microgrids and identifies situations in which solar technologies can be economically viable without government incentives.

Abstract:

As feed-in-tariffs are being phased out, net metering (NM) programs are being enhanced, thus presenting a new opportunity for behind-the-meter renewable electricity generation. This paper analyses the Internal Rate of Return (IRR) on investment in solar microgrids under various NM options. Residential microgrids, based on survey results for residential consumption profiles are shown to have an IRR of 2% - 5% depending on the year in which the project starts. Small business microgrids for office buildings with 3 or 6 floors have a corresponding IRR of 2% - 12%. In order to obtain higher IRRs, we analyse larger business customers that are subject to charges on their peak consumption each month in addition to the charges for electricity consumption which residential and small business customers pay. This paper shows how reducing these peak charges is essential to obtaining a high IRR from solar. If the peak consumption occurs at a time of low solar generation, a battery is necessary and power flow in/out of the battery optimized. The paper presents examples of optimal microgrid control for business customers whose consumption is concentrated during daytime and also for those whose consumption extends into the evening. The results are based on actual hourly data from business customers in Ontario. The paper then presents the IRR corresponding to different sizes of battery. It is shown that IRRs vary from 18% without a battery to 47% with a battery. The battery capacity (in kWh) that maximizes IRR for a given solar capacity (in kW) is determined for the different consumption profiles considered. The analysis takes into account trends in the prices of solar systems, batteries and electricity.

Abstract:

The Maisotsenko cycle (M-cycle) is a proven thermodynamic process, which captures energy from air, utilizing the psychrometric renewable energy available from the latent heat of water evaporating into the air. In air conditioning the M-cycle uniquely combines the thermodynamic processes of heat transfer and evaporative cooling to enable product temperature to approach the ambient dew point temperature. The application of capturing energy from air utilizing the latent heat of evaporation to transfer energy , electric energy generation, engine technology water distillation, all with absolutely no carbon emissions. Maisotsenko cycle fully utilizes the thermodynamic unbalance of the atmospheric air through the process of evaporation, condensation and sensible heat (energy) transfer. The natural unbalance of atmospheric air is based on the enthalpy (i.e. temperature and moisture content) difference between the masses of air, which eventually results in a pressure difference, which creates all the most powerful natural phenomena that can be observed. Maisotsenko cycle creates the same enthalpy difference by cooling one air stream without adding moisture, while heating and humidifying the second air stream.

The principles of M-cycle can be used in any application which requires energy. Most popular application of the Maisotsenko cycle air the air conditioning systems: it is proven that M-Cycle can reduce the energy consumption up to 90% in compare to the traditional solutions. Besides the air conditioning systems, M-Cycle can also be used for effective water desalination, increasing the effectiveness of gas turbines and photovoltaic panels.

Following paper discusses different applications of the Maisotsenko cycle and describes the energy savings which can be obtained.

Dr. Abdesslem Djerdir was born in 1969 and has received the B.S. degree in electrical engineering from the National Institute of Electrical Engineering Bejaia, Algeria, in 1993 and the Ph.D. degree in electrical engineering from University of Franche Comté Belfort, France, in 1999. Currently, he is an Associate Professor at University of Technology Belfort-Montbéliard (UTBM), France. He is habilitated to supervise scientific research since December 2007. His research interests include modelling and design of electric and fuel cell vehicle systems (electrical machines, energy storage devices, and power converters). He develops his main researches on availability and high efficiency of electric drive trains for transport applications by combining the experimental and theoretical approaches. In this framework he was the vehicle referent of the Mobypost project (http://mobypost-project.eu) where 10 fuel cell electrical vehicles were built and tested.

Abstract:

The European project MobyPost (http://mobypost-project.eu/) takes into consideration the whole energy from production to consumption through the innovative solution "from sun to wheel". This is achieved on the one hand, through the development of two hydrogen production stations thanks to the electrolysis of water from solar photovoltaic energy. The Hydrogen thus produced is stored in two buffer tanks installed on two experiment sites in the French Bourgone-Franche-Comté region namely, Audincourt and Perrigny. The project allowed the design and the construction of 10 fuel cell electrical vehicles for the delivery of mail to cover a geographical area within a 25 to 35 km radius around the postal centers. The Mobypost vehicles are feed each day with hydrogen on the buffer tanks. In contrast to high-pressure storage (between 350 and 700 bar) currently used by the known fuel cell electrical vehicles, hydrogen storage in MobyPost vehicles is of the solid type and is at low pressure (between 2 and 10 bar), which offers more safety on board the vehicles. Experimentation achieved during the project highlights the real and actual specifications used nowadays by La Poste to deliver the postal mail in the more effective way. Hence this allows demonstrating the relevance and feasibility of such an innovative approach with nearly zero carbon emission in real working conditions. A further important goal of the project is also to diffuse the results to similar niche markets around Europe like e.g. postal mail operators of others countries, proximity delivery services providers or municipal technical services.

Lisa Altieri graduated in 2015 with a MSc degree in sales engineering and project management at the Ruhr-Universität Bochum and now works as a scientific assistant at the chair of energy systems and energy economics (LEE) of the Ruhr-Universität Bochum. She is involved in the project GW-Ruhr, which examines the existing mining infrastructure and how it can be used in terms of renewable energy generation.

Abstract:

The key issue of the Project Grubenwasser-Ruhr (GW-Ruhr)¹ is the geothermal heating energy supply through the utilization of occurring low energy heat in mine water². The mine water, depending on the pumping location and uplift depth, has a temperature between 15 and 30 °C. The research objective is to use its geothermal energy. Assistive technologies like heat pumps could be used to increase the temperature level of the mine water. The usage of geothermal energy presents an alternative to fossil fuels like oil and gas.

Suitable mine water rising sites will be evaluated with the help of economic and ecological aspects. These evaluations will be the basis for the investments and implementations of a mine water heating system at several locations. Beside the technical aspects a comprehension and cooperation with potential heat customers in the relevant areas will be decisive for the later success. The technical objective is to connect all heat customers to one low-exergy-network. In this way the mine water temperature will be transported to the customer with low losses and a heat pump will raise the temperature for the individual customer requirements. With this concept more than 70 percent of heat from mine water can be used.

Abstract:

Globally, with the increasing liberalization of the energy market, opportunities to the emergence of new actors and innovative structures arise. One of these new actors is the Virtual Power Plant (VPP), an entity that aggregates generation and loads capacity, in order to create a single operating profile from a composite of the parameters characterizing each aggregated resource. This article explains the actual Brazilian regulatory framework for implementing Virtual Power Plants and estimates a roadmap for the creation of each market in which Virtual Power Plants could participate, contributing to understand the market potential of this new actor in the Brazilian scenario and the novel opportunities for monetizing resources while optimizing the electric grid operation. In the current regulatory scenario Demand Response (DR) figure does not exist and, therefore, it is not yet considered in regulation improvements. In addition, in terms of the energy market, the possibility of contracting ex post does not allow DR participation (characterized by a pre-sale of capacity). In this current context, VPP operators could only offer services to substitute generators value, but not the value of flexibility, represented by demand response resources. Furthermore, capacity and balancing markets do not exist yet, and therefore VPPs have limited opportunities of monetizing aggregation. Some of ongoing efforts in Brazil that are expected to contribute to leverage flexibility include an industrial demand-response pilot program (considering free consumers in North and Northeast subsystems), approved in November 2017 and valid until June 2019. The pilot aims to prove the value of Demand Response as an alternative for operating reserve and frequency regulation, encouraging a future regulation. Demand Response will be used in this pilot to supply operating reserve, peak power and frequency regulation. However, a series of trends indicate the future creation of different markets in which VPPs could participate.

Johan Manuel Redondo has completed his PhD and postdoctoral studies from National University of Colombia. He is the president of the Society for Industrial and Applied Mathematics - Colombian Section and Director of the research group "Economics and sustainable development" of the Catholic University of Colombia. He has published so interesting papers in reputed journals about the modeling of complex systems like energy markets.

Abstract:

The regional integration of electricity markets has been considered a desirable objective for Latin American nations. However, the establishment of rules that allow the articulation from the technical and economic perspective, are not enough, given the significant number of stakeholders and social and environmental aspects that must be taken into account. In this way, a mathematical model was developed for doing the assessment of different strategies that should be considered, obtaining prospective scenarios and the dependence that these scenarios have on parameters and it is proposed to make certain considerations. In spite of this, the model does not allow to account for social and environmental issues whose complexity is different along the sections that must be designed, constructed and operated, in order to realize the necessary expansion of the electrical transmission required to supply the new demands of an integrated international market. For this reason, two methodologies were developed to address the social and environmental considerations of the energy system, in the approach to the implementation of sustainable energy systems, which includes renewable energy systems. In the first methodology developed, the socioenvironmental sensitivity of the landscape is analyzed, based on the analysis of the network of direct, indirect and cumulative (additive and synergic) relationships of anthropic interventions such as those related to the design, construction and operation of transmission lines. With the second methodology, the aim is to systemically analyze landscape emergencies such as wellbeing and sustainability, so that different landscape units are made comparable and projects related to the development of projects associated with energy markets can be established timely and assertively. The results obtained include sensitivity maps constructed in geographic information systems, network analysis, bifurcation analysis and simulations of different scenarios. It is concluded that the analysis of a complex issue such as electricity markets merits an analysis from different theoretical perspectives aimed at guaranteeing sustainability in the economy, the environment and society.

Abstract:

The Northern off-grid power systems in Canada mostly rely on diesel as their primary energy resource. Many of these communities do not have overland roads and therefore rely on winter roads for transportation of diesel. Transportation of diesel over winter roads is costly and hazardous to both people and environment. On the other hand, growing fuel prices and the adverse effects of increased carbon footprint have shifted the energy policies to favor more environmentally healthy approaches. In this context, Hybrid Renewable Energy Systems (HRES) deploying locally available renewable energy sources and energy storage methods have emerged as perfect candidates to compete with the existing diesel-based facilities. High penetration of renewable sources is expected to reduce, optimize or replace diesel-based energy production while increasing the carbon-free generation capacity. To maximize the envisioned benefits, technology selection, optimum sizing and performance evaluation have become decisive steps in the designing process of HRES. This study aims to find the optimum HRES retrofit  for an exiting diesel-based off-grid power system. The desicion variables employed in the optimization process ensure the technical feasibility and economic viability of the selected configurations while indirectly addressing their envionmental friendliness. Four HRES configurations with increasing renewable penetration were optmized using NREL’s HOMER software platform. The performance of each optimized system was assessed in terms of economical, technological and environmental criteria. Results reveal the competence of HRES in delivering high envionmental performance, energy security and enhanced reliability while achieveing fuel savings up to 20-23%.

He has published many papers in reputed journals and has been serving as a regular reviewer of many reputed journals.

Abstract:

The production of H2 on small scale via sorption enhanced steam reforming (SE-SMR) of CH₄ using 18 wt. % Ni/ Al2O₃ catalyst and CaO as a CO₂-sorbent was simulated for an adiabatic packed bed reactor. To study the behaviour of reactor model along the axial direction, the mass, energy and momentum balance equations were incorporated in the gPROMS model builder. The effect of operating conditions such as temperature, pressure, steam to carbon ration (S/C) and gas mass flow velocity (Gs) was studied under the low pressure conditions. Independent equilibrium based software, chemical equilibrium with application (CEA), was used to compare the simulation results with the equilibrium data. A good agreement was obtained in terms of CH4 conversion, H2 yield (wt. % of CH₄ feed), purity of H₂ and CO₂ capture under the different operating conditions of temperature, pressure, S/C and Gs. A pressure of 3 bar, 873 K and S/C of 3 can result in CH₄ conversion and H₂ purity up to 99% and 95% respectively compared to 36% and 59% in the conventional reforming process.

Abstract:

The use of nuclear energy for cogeneration of heat and power is a well-proven path with over 750 reactor-years of operation, mainly in district heating and desalination applications. Nuclear cogeneration is one of the most promising clean alternatives to serve towards achieving sustainable development by contributing to cover part of the continuously growing energy demands worldwide for industrial processes, transportation, industry, residential applications, along with many other sectors. The projects of nuclear cogeneration serve the main elements of sustainability: energy, environment, and cost. Advanced nuclear reactors incorporating cogeneration features are expected to provide more environmentally benign energy systems operating at higher energy efficiency. Furthermore, the recovery of waste heat of nuclear power plants for cogeneration applications would lead to a direct reduction of the overall plant losses and emissions.

The IAEA conducts several activities to support its Member States interested in non-electric applications and cogeneration using nuclear energy. The IAEA also developed several tools to elaborate on the feasibility and technoeconomics of nuclear desalination, district heating, and hydrogen production applications. This paper highlights the aspects of the use of the nuclear energy for non-electric applications and cogeneration, and discusses the main activities of the IAEA on related topics. In addition, the IAEA software tools and toolkits, which are developed to provide support to Member States with more understanding on the economic viability of nuclear cogeneration options, are highlighted.
