The target audience are those engaging in the research and technical management of the underground gas storage. It's a valuable reference for both reseachers and college students as well in the fields of underground storage of carbon dioxide (CO2) and helium (He), Power to Gas energy accumulation.

Advanced high-performance materials enabling precise control of chemical change, characterization tools probing the ultrafast and the ultra small, and new understanding based on advanced theory and simulation are the agents for moving beyond incremental improvements and creating a truly secure and sustainable energy future. This symposium proceedings volume focuses on the synthesis, processing, characterization, and modelling of nanostructured materials and their potential use as "nanoscale building blocks" for photon, phonon and chemical transduction to electrical signal and vice versa for energy management. Nanoscale structures can dramatically alter surface reaction rates and electrical transport, resulting in improvements in the processes and transduction mechanisms concerning energy storage, conversion, and generation.

This book focuses on a group of new materials labeled "graphene oxides." It provides a comprehensive overview of graphene oxide-based nanomaterials in terms of their synthesis, structures, properties, and extensive applications in catalysis, separation, filtration, energy storage and conversion. The book also covers emerging research on graphite oxides and the impact of the research on fundamental and applied sciences.

This book addresses the needs of researchers in electrical engineering interested in the modeling, simulation, dynamics and bifurcations of switched mode power supplies. It presents in a comprehensive and pedagogical manner, state-of-the-art research on bifurcation prediction in switched mode power supplies, which will help yield design-oriented results for power electronics practitioners.

The expected end of the "oil age" will lead to increasing focus and reliance on alternative energy conversion devices, among which fuel cells have the potential to play an important role. Not only can phosphoric acid and solid oxide fuel cells already efficiently convert today's fossil fuels, including methane, into electricity, but other types of fuel cells, such as polymer electrolyte membrane fuel cells, have the potential to become the cornerstones of a possible future hydrogen economy. This handbook offers concise yet comprehensive coverage of the current state of fuel cell research and identifies key areas for future investigation. Internationally renowned specialists provide authoritative introductions to a wide variety of fuel cell types and hydrogen production technologies, and discuss materials and components for these systems. Sustainability and marketing considerations are also covered, including comparisons of fuel cells with alternative technologies.
