I have a broad background in utilities and energy. I worked for Capgemini in the Energy Practice for more than 15 years. During that time I rose to the position of CTO of the 12,000 person...

Almost Perfect (in the lab) New Solar Direct conversion of sunlight to hydrogen... Rice University has managed to run a lab scale solar to hydrogen converter for 102 hours, and using a new water proof coating on the solar cells, converted sunlight to hydrogen at a 20% rate (normal PV is 21% efficient at converting sunlight to electricity). Now it has to scale, operate for thousands of hours, and the cost has to be reduced to a commercially acceptable level. By 2030 or 2035 if everything goes right, instead of 70% conversion, we may be at 95% conversion of sunlight to hydrogen. But the path is long and many lab level devices never make it to commercial scale. I wish them luck.

High-efficiency photoelectrodes, which integrate light absorption with catalysis, have been limited to costly materials. Here, the authors develop an anticorrosion barrier that enables low-cost semiconductors for integrated solar fuel devices with 20.8% s
