Advances in Hydrogen Energy

This book, which is a reprint of articles published in the Special Issue "Advances in

Hydrogen Energy" in Energies, seeks to contribute to disseminating the most recent

advancements in the field of hydrogen energy. It does so by presenting scientific works

from around the world covering both modeling and experimental analysis. The focus is

placed on research covering all aspects of the hydrogen energy, from production to

storage and final use, including the development of other easy to transport and versatile

hydrogen-based energy carriers via the power-to-x (PtX) route, such as ammonia and

methanol.

Hydrogen energy research and development has attracted growing attention as one of

the key solutions for clean future energy systems. In order to reduce greenhouse gas

emissions, governments across the world are developing ambitious policies to support

hydrogen technology, and an increasing level of funding has been allocated for projects

of research, development, and demonstration of these technologies. At the same time,

the private sector is capitalizing on the opportunity with larger investments in hydrogen

technology solutions.

While intense research activities have been dedicated to this field, several issues require

further research prior to achieving full commercialization of hydrogen technology

solutions. This book addresses some of these issues by presenting detailed models to

optimize design strategies and operating conditions for the entire hydrogen value chain,

covering production via electrolysis, storage and use in different types of fuel cells and in

different forms of energy carriers.
