MIT claims 24/7 solar power [more on new electrolysis claim]:D

"Solar cell makers can add super-cheap electrolyzers to their system so that they work 24/7 -- during the day making hydrogen and oxygen, then at night recombining it in fuel cells to generate electricity," Nocera predicted.

PORTLAND, Ore. Researchers at the Massachusetts Institute of Technology have combined a liquid catalyst with photovoltaic cells to achieve what they claim is a solar energy system that could generate electricity around the clock.

A liquid catalyst was added to water before electrolysis to achieve what the researchers claim is almost 100-percent efficiency.

When combined with photovoltaic cells to store energy chemically, the resulting solar energy systems could generate electricity around the clock, the MIT team said. "The hard part of getting water to split is not the hydrogen -- platinum as a catalyst works fine for the hydrogen....

The exemption for solar energy is getting ready to expire. What a bunch of dumb ass politicians we have.

This system looks good.The problem has always been energy storage.
By converting directly from sunlight to liquid gas storage they save on a bunch of conversion losses.
If this is done on a large enough scale in the American South West we could have a reliable new source of energy.The key is as usual new membrane technology breakthroughs. Hydrogen storage
in nano-tubes is another great development.
