Energy generation and storage: Special consideration to Hydrogen Energy

Energy is characterized by several aspects ranging from the generation ways to its sustainability, through conservation, transformation, use, transfer, storage, etc. The present Special issue considers all these various aspects but particularly focussing on Hydrogen energy upon which most of the energy economy policies are nowadays based due to its outstanding properties like the possibility for its transformation into a valuable renewable and clean energy source, excluding any emissions, greenhouse effect, toxicity, etc. However all these different aspects are under explored, hence encouraging the consideration of sensitive issues like its production, storage, valorization, etc. which are mainly influenced by the small size of the hydrogen molecules, requiring sufficiently high pressure conditions for a reasonable energy density easing its storage. Also the natuaral volatilty of hydrogen and its highly flammabity do make it difficult to transport. Therefore, all these factors are challenges motivating the consideration of this source of energy. The proposed Special Issue aims to examine the recent achieved advances and the resulting applications, by inviting academic scientists and researchers. Various topics may be treated like: Modeling and simulation; Process optimization, Energy efficiency; Non-conventional processes, etc., regarding Hydrogen energy but in the same time without excluding other energy types.

Corresponding papers will be peer reviewed by specialized and experienced reviewers and eventually accepted for publication in Energy Engineering journal.
