Electrolysis using renewable energy

What must be considered in reactions (2.149) and (2.150) is the source of H2. It is clear that traditional reactions (water-gas shift and CH4 reforming) cannot be used and that H2 must be generated via water electrolysis using renewable energy sources such as solar radiation. Thus, the argument that it is preferable to use H2 directly as a fuel is inconsistent with our aim of carbon cycling. Moreover, carbon carriers provide a range of products that are better suited to the available infrastructure than H2. Overall, the photosynthesis-like reactions (2.151) and (2.152) are carried out ... 

The goal is to use renewable energy to make hydrogen from water via electrolysis. When the wind with current wind turbines which can perform at 30-40% efficiency, producing hydrogen at an overall 25% efficiency.

The use of organic chemical hydrides on the basis of superheated liquid-film concept would, thus, make it possible to combine electrolysis hydrogen produced from renewable energy and by-product hydrogen recovered from various industrial processes, with the hydrogen demand practically for stationary fuel cells and hydrogen vehicles. 

The new frontiers of hydrogen energy systems described in this paper will be PEM-electrolysis combined with renewable energy sources, biolysis with use of biological methods based on the genetics, and mechanolysis combined with any moving phenomenon and object, in hydrogen production area.

However, this method is not economically feasible for all applications due to power requirements. Electrolysis has been used for long wherever electric power is available cheap or pure hydrogen was needed or where there is a renewable energy source available. 

These fuels (pure H2, H2/C02, and H2/C0/C02) can also be produced from renewable energy sources—biomass, solar, windmills, and hydroelectric power. On the other hand, pure H2 can be generated by water electrolysis using nuclear power plants. Hydrogen is the most electro-reactive fuel for fuel cells operating at low and intermediate temperatures.
