Box 378, Ethiopia; [email protected] * Correspondence: [email protected]; Tel.: +32-485659951 or +251-926434658 Received: 12 November 2020; Accepted: 11 December 2020; Published: 15 December 2020 Abstract: Renewable energy sources (RESs) such as wind and solar are frequently hit by fluctuations due to, for example, insufficient wind or sunshine. Energy storage technologies (ESTs) mitigate the problem by storing excess energy generated and then making it accessible on demand. While there are various EST studies, the literature remains isolated and dated. The comparison of the characteristics of ESTs and their potential applications is also short. This paper fills this gap. Using selected criteria, it identifies key ESTs and provides an updated review of the literature on ESTs and their application potential to the renewable energy sector. The critical review shows a high potential application for Li-ion batteries and most fit to mitigate the fluctuation of RESs in utility grid integration sector. -
Electrical Energy Storage
08 Fall BACKGROUND The Energy Systems Toolkit (the „Toolkit‟) is aimed at organisations, community groups or businesses, at different stages in the project development process, whether exploring ideas to develop into a project or additional options to include in a current project. The Toolkit aims to provide further information to organisations on energy systems topics that will help determining whether a project idea is viable or highlight alternative options that should be considered. The Toolkit also provides support through the development process to construction, highlighting any support available to them. This could include: Signposting businesses or communities to additional support (technical or financial) in developing their project, to potential project partners or to potential sources of funding; Provide detail on key considerations and barriers across different technology projects; or Highlight different technology projects and themes that have been developed successfully across Scotland. For each of the topics, the guidance provided will be informative and will indicate the actions to be taken and the next steps the organisations should take to progress. The Toolkit links to other relevant guidance documents, such as the CARES Toolkit, which can be used in parallel. INTRODUCTION TO ELECTRICAL ENERGY STORAGE Electrical energy storage can provide a range of grid support services that can help maintain a stable and reliable electricity supply. Working in tandem with smart grid technology, the functions that it can provide include: Enabling the integration of more renewables into the energy mix. Storing energy from renewables to smooth variable supply. Helping energy consumers to manage their energy demand. Stabilising voltage and frequency on power networks. -
Energy and the Hydrogen Economy
Energy and the Hydrogen Economy Ulf Bossel Fuel Cell Consultant Morgenacherstrasse 2F CH-5452 Oberrohrdorf / Switzerland +41-56-496-7292 and Baldur Eliasson ABB Switzerland Ltd. Corporate Research CH-5405 Baden-Dättwil / Switzerland Abstract Between production and use any commercial product is subject to the following processes: packaging, transportation, storage and transfer. The same is true for hydrogen in a “Hydrogen Economy”. Hydrogen has to be packaged by compression or liquefaction, it has to be transported by surface vehicles or pipelines, it has to be stored and transferred. Generated by electrolysis or chemistry, the fuel gas has to go through theses market procedures before it can be used by the customer, even if it is produced locally at filling stations. As there are no environmental or energetic advantages in producing hydrogen from natural gas or other hydrocarbons, we do not consider this option, although hydrogen can be chemically synthesized at relative low cost. In the past, hydrogen production and hydrogen use have been addressed by many, assuming that hydrogen gas is just another gaseous energy carrier and that it can be handled much like natural gas in today’s energy economy. With this study we present an analysis of the energy required to operate a pure hydrogen economy. High-grade electricity from renewable or nuclear sources is needed not only to generate hydrogen, but also for all other essential steps of a hydrogen economy. But because of the molecular structure of hydrogen, a hydrogen infrastructure is much more energy-intensive than a natural gas economy. In this study, the energy consumed by each stage is related to the energy content (higher heating value HHV) of the delivered hydrogen itself. -
NASA Radioisotope Power Conversion Technology NRA Overview
NASA Radioisotope Power Conversion Technology NRA Overview David J. Anderson NASA Glenn Research Center, 21000 Brookpark Road, Cleveland, OH 44135 216-433-8709, [email protected] Abstract. The focus of the National Aeronautics and Space Administration’s (NASA) Radioisotope Power Systems (RPS) Development program is aimed at developing nuclear power and technologies that would improve the effectiveness of space science missions. The Radioisotope Power Conversion Technology (RPCT) NASA Research Announcement (NRA) is an important mechanism through which research and technology activities are supported in the Advanced Power Conversion Research and Technology project of the Advanced Radioisotope Power Systems Development program. The purpose of the RPCT NRA is to advance the development of radioisotope power conversion technologies to provide higher efficiencies and specific powers than existing systems. These advances would enable a factor of 2 to 4 decrease in the amount of fuel and a reduction of waste heat required to generate electrical power, and thus could result in more cost effective science missions for NASA. The RPCT NRA selected advanced RPS power conversion technology research and development proposals in the following three areas: innovative RPS power conversion research, RPS power conversion technology development in a nominal 100We scale; and, milliwatt/multi-watt RPS (mWRPS) power conversion research. Ten RPCT NRA contracts were awarded in 2003 in the areas of Brayton, Stirling, thermoelectric (TE), and thermophotovoltaic (TPV) power conversion technologies. This paper will provide an overview of the RPCT NRA, a summary of the power conversion technologies approaches being pursued, and a brief digest of first year accomplishments. RADIOISOTOPE POWER CONVERSION TECHNOLOGY (RPCT) OVERVIEW The objective of the National Aeronautics and Space Administration’s (NASA) Radioisotope Power Systems (RPS) Development program is to develop nuclear power conversion technologies that would improve the effectiveness of space science missions. -
Hydroelectric Power -- What Is It? It=S a Form of Energy … a Renewable Resource
INTRODUCTION Hydroelectric Power -- what is it? It=s a form of energy … a renewable resource. Hydropower provides about 96 percent of the renewable energy in the United States. Other renewable resources include geothermal, wave power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up resources to create electricity nor do they pollute the air, land, or water, as other powerplants may. Hydroelectric power has played an important part in the development of this Nation's electric power industry. Both small and large hydroelectric power developments were instrumental in the early expansion of the electric power industry. Hydroelectric power comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity. Hydroelectric power is important to our Nation. Growing populations and modern technologies require vast amounts of electricity for creating, building, and expanding. In the 1920's, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate and hydroelectric power presently supplies about 10 percent of the electrical generating capacity of the United States. Hydropower is an essential contributor in the national power grid because of its ability to respond quickly to rapidly varying loads or system disturbances, which base load plants with steam systems powered by combustion or nuclear processes cannot accommodate. Reclamation=s 58 powerplants throughout the Western United States produce an average of 42 billion kWh (kilowatt-hours) per year, enough to meet the residential needs of more than 14 million people. -
The Impacts of Storing Solar Energy in the Home to Reduce Reliance on the Utility
ARTICLES PUBLISHED: XX MONTH XXXX | VOLUME: 2 | ARTICLE NUMBER: 17001 The impacts of storing solar energy in the home to reduce reliance on the utility Robert L. Fares* and Michael E. Webber There has been growing interest in using energy storage to capture solar energy for later use in the home to reduce reliance on the traditional utility. However, few studies have critically assessed the trade-os associated with storing solar energy rather than sending it to the utility grid, as is typically done today. Here we show that a typical battery system could reduce peak power demand by 8–32% and reduce peak power injections by 5–42%, depending on how it operates. However, storage ineciencies increase annual energy consumption by 324–591 kWh per household on average. Furthermore, storage operation indirectly increases emissions by 153–303 kg CO2, 0.03–0.20 kg SO2 and 0.04–0.26 kg NOx per Texas household annually. Thus, home energy storage would not automatically reduce emissions or energy consumption unless it directly enables renewable energy. 1 n recent years, there has been growing interest in storing energy lead-acid batteries used with solar panels in the UK would increase 41 25 2 produced from rooftop photovoltaic panels in a home battery both primary energy consumption and carbon dioxide emissions . 42 1 3 Isystem to minimize reliance on the electric utility .

Països Catalans No. 26, 43007 Tarragona, Spain * Correspondence: [email protected] Received: 7 June 2020; Accepted: 7 July 2020; Published: 13 July 2020 Abstract: A thermoelectric effect is a physical phenomenon consisting of the direct conversion of heat into electrical energy (Seebeck effect) or inversely from electrical current into heat (Peltier effect) without moving mechanical parts. The low efficiency of thermoelectric devices has limited their applications to certain areas, such as refrigeration, heat recovery, power generation and renewable energy. However, for specific applications like space probes, laboratory equipment and medical applications, where cost and efficiency are not as important as availability, reliability and predictability, thermoelectricity offers noteworthy potential. The challenge of making thermoelectricity a future leader in waste heat recovery and renewable energy is intensified by the integration of nanotechnology. In this review, state-of-the-art thermoelectric generators, applications and recent progress are reported. Fundamental knowledge of the thermoelectric effect, basic laws, and parameters affecting the efficiency of conventional and new thermoelectric materials are discussed. The applications of thermoelectricity are grouped into three main domains. -
Electrical Energy
Chapter 5 Electrical Energy Our modern technological society is largely defined by our widespread use of elec- trical energy. Electricity provides us with light, heat, refrigeration, communication, elevators, and entertainment. We are so dependent on electricity that when it is unavailable for even a few minutes, the word “crisis” comes to mind. Electrical energy is popular because it is so easily transmitted from one place to another, and converted into other forms of energy. The concepts and principles of electricity are beautiful and intricate, but this is hardly the place to present them in complete detail. For a more thorough treatment of the subject, you can consult almost any standard introductory physics textbook. Electric Charge The simplest electrical phenomenon is static electricity, the temporary “charg- ing” of certain objects when they are rubbed against each other. Run a comb through your hair when it’s dry, and the hair and comb begin to attract each other, indicating that they are charged. Other familiar examples include clothes sticking together in the dryer, and the sudden shock that you sometimes get when shaking someone’s hand after walking across a carpet with rubber-soled shoes. What you may not have noticed is that static electricity can result in both attractive and repulsive forces. The comb attracts the hair and vice-versa, but the hairs repel each other, and two combs similarly charged will likewise repel each other. To explain this we say that there are two types of electric charge, called positive and negative. When objects become charged by rubbing against each other, one always becomes positive and the other becomes negative.
