Electrolysis of Water

Electrolysis Nafion Stack Anode Cathode

Personally, I think that 400 years hence the power question in England may be solved somewhat as follows. The country will be covered with rows of metallic windmills working electric motors, which in their turn supply current at a very high voltage to great electric mains. At suitable distances there will be great power stations where during windy weather the surplus power will be used for the electrolytic decomposition of water into hydrogen and oxygen In times of calm, the gases will be...

Low Cost Hydrogen from Hybrid CPV Systems

Wind Hybrid System Schema

We are now in a position to understand why this new high-efficiency solar electric technology provokes a fresh look at the challenge of generating hydrogen from water using sunlight. In addition to generating solar electricity at low cost, CPV systems have the potential to produce hydrogen through an electrolysis process. The generation of electrolytic hydrogen from solar energy is critically important to the world's long-term energy needs for several reasons. The feedstock water and supplied...

Describing the Hybrid CPV System

Solar Hydrogen Civilization

This approach first proposed by Solar Systems in Australia employs a dish concentrator that reflects sunlight onto a focal point see Fig. 6 . At the focal point is a spectral splitter heat mirror that reflects infrared solar radiation and transmits the visible sunlight to high-efficiency solar cells behind the spectral splitter. Figure 7 schematically shows the transmission across the solar spectrum wavelengths. The reflected infrared radiation is gathered by a fiber-optics light pipe and...
