Gravity Energy Storage


Book Description

Gravity Energy Storage provides a comprehensive analysis of a novel energy storage system that is based on the working principle of well-established, pumped hydro energy storage, but that also recognizes the differences and benefits of the new gravity system. This book provides coverage of the development, feasibility, design, performance, operation, and economics associated with the implementation of such storage technology. In addition, a number of modeling approaches are proposed as a solution to various difficulties, such as proper sizing, application, value and optimal design of the system. The book includes both technical and economic aspects to guide the realization of this storage system in the right direction. Finally, political considerations and barriers are addressed to complement this work. - Discusses the feasibility of gravity energy storage technology - Analyzes the storage system by modelling various system components - Uniquely discusses the characteristics of this technology, giving consideration to its use as an attractive solution to the integration of large-scale, intermittent renewable energy

Renewable Energy in District Heating and Cooling


Book Description

District heating and cooling (DHC) combined with renewable energy sources can help meet rising urban energy needs, improve efficiency, reduce emissions and improve local air quality. Although currently dominated by fossil fuels such as coal and gas, DHC systems can be upgraded, or new networks created, to use solid biofuel, solar and geothermal energy technologies. Depending on local conditions, renewable-based DHC brings a range of benefits, including increased energy security, improved health and reduced climate impact.To date, only a few countries have taken advantage of their renewable resource potential for DHC or created policies to promote further uptake. Sweden and Switzerland have started promoting renewable-based district heating,while Denmark - with ambitious decarbonisation policies -already uses high shares. Many cities and regions envisage a growing role for district in their energy plans; some are also looking increasingly at district cooling.As this REmap sector study from the International Renewable Energy Agency (IRENA) shows, renewables could feasibly supply more than one fifth of the energy needed for DHC worldwide. But to drive the transition, policy makers need to fully understand the costs, bene¿ts and actual potential for renewable-based DHC.




Advances in Concentrating Solar Thermal Research and Technology


Book Description

After decades of research and development, concentrating solar thermal (CST) power plants (also known as concentrating solar power (CSP) and as Solar Thermal Electricity or STE systems) are now starting to be widely commercialized. Indeed, the IEA predicts that by 2050, with sufficient support over ten percent of global electricity could be produced by concentrating solar thermal power plants. However, CSP plants are just but one of the many possible applications of CST systems. Advances in Concentrating Solar Thermal Research and Technology provides detailed information on the latest advances in CST systems research and technology. It promotes a deep understanding of the challenges the different CST technologies are confronted with, of the research that is taking place worldwide to address those challenges, and of the impact that the innovation that this research is fostering could have on the emergence of new CST components and concepts. It is anticipated that these developments will substantially increase the cost-competiveness of commercial CST solutions and reshape the technological landscape of both CST technologies and the CST industry. After an introductory chapter, the next three parts of the book focus on key CST plant components, from mirrors and receivers to thermal storage. The final two parts of the book address operation and control and innovative CST system concepts. - Contains authoritative reviews of CST research taking place around the world - Discusses the impact this research is fostering on the emergence of new CST components and concepts that will substantially increase the cost-competitiveness of CST power - Covers both major CST plant components and system-wide issues




Energy Storage Devices


Book Description

Energy storage will be a very important part of the near future, and its effectiveness will be crucial for most future technologies. Energy can be stored in several different ways and these differ in terms of the type and the conversion method of the energy. Among those methods; chemical, mechanical, and thermal energy storage are some of the most favorable methods for containing energy. Current energy storage devices are still far from meeting the demands of new technological developments. Therefore, much effort has been put to improving the performance of different types of energy storage technologies in the last few decades.

Stand-Alone and Hybrid Wind Energy Systems


Book Description

Wind power is fast becoming one of the leading renewable energy sources worldwide, not only from large scale wind farms but also from the increasing penetration of stand-alone and hybrid wind energy systems. These systems are primarily of benefit in small-scale applications, especially where there is no connection to a central electricity network, and where there are limited conventional fuel resources but available renewable energy resources. By applying appropriate planning, systems selection and sizing, including the integration of energy storage devices to mitigate variable energy generation patterns, theses systems can supply secure reliable and economic power to remote locations and distributed micro-grids.Stand-alone and hybrid wind energy systems is a synthesis of the most recent knowledge and experience on wind-based hybrid renewable energy systems, comprehensively covering the scientific, technical and socio-economic issues involved in the application of these systems.Part one presents an overview of the fundamental science and engineering of stand-alone and hybrid wind energy systems and energy storage technology, including design and performance optimisation methods and feasibility assessment for these systems.
