Hydrogen is not a primary energy source, because it is not naturally occurring as a fuel. It is, however widely regarded as an ideal energy storage medium, due to the ease with which electric power can convert water into its hydrogen and oxygen components through electrolysis and can be converted back to electrical power using a fuel cell.  Methods of hydrogen storage for subsequent use span many approaches, including high pressures, cryogenics, and chemical compounds that reversibly release H2 upon heating.

Hydrogen storage is useful to provide grid energy storage for intermittent renewable sources (like CSP, PV, wind power, etc.) as well as providing fuel for transportation (cars, ships and airplanes).

Objectives: 

ARES is mainly involved in research and development of fully integrated solutions for hydrogen generation from renewable sources, safe hydrogen storage and efficient utilization by end users in stationary or portable applications.
In particular, ARES will focus his research activities in the field of chemical hydrogen storage, exploring two main approaches:

  • Innovative solid state materials: some metal hydrides can be used as a storage medium for hydrogen, often reversibly, which could be turned into pellets. These materials have good energy density by volume, providing low reactivity (high safety) and high hydrogen storage densities;
  • Carbonite substances: Graphene is produced as a powder and as a dispersion in a polymer matrix, or adhesive, elastomer, oil and aqueous and non-aqueous solutions. Research results has proven that not only graphene can store hydrogen efficiently and easily, it can also release the hydrogen again, after heating to 450 °C. Despite the graphene is not diffused in commercial applications, many investigations have been proposed and/or are under development in different application areas, including energy storage.
