A study of hydrogen as an energy vector for future renewable energies.

This work presents the importance of hydrogen as one of the main energy vectors of renewable energies, and especially for offshore generation. This paper contains the process of generating offshore renewable energy which includes wind, tidal and wave turbines. The steps needed to produce hydrogen are described with the use of electrolyzes and fuel cells. Furthermore, hydrogen is presented as the main potential of storing surplus energy and as the major fuel for road vehicles, marines transports and aerospace industries. This work presents potential of using the unemployed Oil & Gas platform for conversion of renewable power to generate hydrogen on offshore stations. The data analysis is presented to assess the efficiency of on-site conversion station. Losses and efficiency of power electronics used from generating electricity to gas and reverse back to electricity via the use of fuel cells is given and the process is explained.
