看来比太阳能电池成本要低，而且能量密度和效率高很多：
“The catalyst operates at 100 mA/cm2 at 76% efficiency. Moreover it can operate out of any water source including the Charles River in front of MIT. Finally, the ability to split neutral water has led to the discovery on an inexpensive H2 producing catalyst that operates at 1000 mA/cm2 at 35 mV overpotential. These catalyst discoveries have enabled the construction of inexpensive water splitting devices that may be coupled to either a photovoltaic panel or coupled directly to the surface of a semiconducting substrate (thus eliminating the module costs associate with a photovoltaic panel).”
