In an era of increasing contributions from intermittent renewable resources, energy storage is becoming more important to ensure a resilient/reliable electricity supply. This book presents the technology, integration and market aspects of energy storage in the various generation, transmission, distribution, and customer levels of the grid.

The sustainable energy sources are potentially employed to substitute petrol fuels in transport engines such as buses and small vehicles. Hydrogen-enriched compressed natural gas engines are forthcoming energy carriers for the internal combustion engine, with higher thermal efficiency and less pollutant emissions. The different availability of renewables has allowed various countries to adopt the most appropriate type of renewable energy technology according to their energy source adequacy/abundance. In Taiwan, ocean energy is considered as an abundant source of renewables due to its geographical location as an island. The Taiwanese government has approved the investment to construct an MW-scale demonstration electricity plant. In this book, the Taiwanese ocean energy experience is comprehensively presented. The technical and legal analyses of ocean energy implementation are provided. The challenges that they had to overcome to optimize the utilization of the most available ocean energy potential are discussed. The sustainable transition in South Africa would be a good example for implementing rooftop solar, especially in low-income communities. Apart from the environmental benefits, sustainable energy technologies can boost the socioeconomic level of developing countries. Other advantages may be the continuous supply of energy and creation of new job opportunities. Moreover, sustainable renewable energy sources such as the wind could be employed for generating electricity to operate water purification systems in remote areas. This, in turn, would overcome the health problems associated with drinking water scarcity issues. This book is an attempt to cover the sustainable energy issues from a technical perspective. Furthermore, the sustainable energy applications and existing case studies are helpful illustrations for the broad understanding of the importance of sustainable energy.

Besides new methods of generating energy, the storage of that energy is a highly important topic, with new technologies in great demand. This book offers readers a range of potential options, maximizing the possibility for success. Several chapters offer overviews of the future of such systems and estimations of their feasibility. Forms of energy storage covered include electrochemical, compressed air and flywheel systems. Other techniques addressed are the use of single- and double-switch cell voltage equalizers and hybrid energy storage and applications. Dynamic energy storage methods are also covered by two chapters. Finally, there are contributions on a low-voltage DC system with storage and distributed generation interfaced systems, and the in-situ dynamic characterization of energy storage and conversion systems.
