Hydrogen Vision Using Hybrid Solar Concentrators

9 Hydrogen Vision Using Hybrid Solar Concentrators 

National Research Council and National Academy of Engineering believes that one of the four most fundamental technological and economic challenges for the hydrogen economy is  

Hybrid CPV electrolysis19 (assuming centralized generation of H2A analysis) 3.18 

The hybrid solar concentrator is a potential leap frog technology that may rapidly lower the cost of clean hydrogen in light of the following the imminent market entry of CPV systems for electricity production solar cell efficiencies above 40%, with clearer ideas for 50%-efficient solar cells and the opportunity to use wasted solar heat for augmenting solar electrolysis. 

An innovative hybrid CPV electrolysis technology has been described that offers a potential cost of hydrogen lower than that from wind electrolysis and in the same range as gasoline for much of the world s population. The analysis is preliminary, but additional cost analysis and technology demonstrations are warranted.
