In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.

This is an old idea not new.
The fact that oxygen is also stored and used in the fuel cell makes it very efficient. 20 liters of water requires 1700 kWh’s to electrolyze. Compare that to batteries! That means when those gases of h2 and o2 are recombined they liberate almost the same level of energy!
@barwick11 maybe the revolutionary part is the catalyst, aside from that fuel cells have been in development for decades, so yeah, nothing really revolutionary about them
A fuel cell is revolutionary? It’s expensive and somewhat inefficient. It’s another method sure, but I wouldn’t call it any more revolutionary than flywheel or mechanical (water tower/reservoir) energy storage.
New? Isn’t this just the same old electrolysis. Battery tech is more efficient but on large scale is still about TWENTY TIMES MORE EXPENSIVE THAN MOLTEN SALTS. Therefore, the solution is in thousands of sq mi of mirrors pinpointing the light that heats the salt. Temps are high enough to run a Brayton cycle!
So what’s the deal with that?
for msn1956, Just gotta hope that the big bad wolf don’t come along and blow your tent down.
I believe that Dr. Nocera has a brilliant idea here, also that the latent heat would also be used for our comfort.. I was giving our customers passive solar hot water systems when they bought their new homes back in 1990′s and I’m sure that the system paid for itself in four to five years, then the energy savings went directly into their pockets, excluding maintenance costs of course..
a Hydrogen & Oxygen system using water if great, for a while but with population increase means we will be burning up the resources needed to sustain life on this planet, the Earth itself emits tons of hydrogen already into space from electrified lightning events per day which only speeds up the process of drying up the water available over the course of thousands of years. this planet will run out of water sooner as the population grows by the square of the law of breeding.
Imagine if they figure out a way to do this with ocean water, this is encouraging
right on Gilmore – like if we could all live in tents that would be real energy efficient – Cool !!
Why doesn’t the government regulate all new houses being built to come with solar panels and a storage system ??
then people would have to buy smaller to compensate for the cost. Saving money on less junk to fill thier houses with..and so on. I mean wake up!!
hey there is actually a supercar electric, 0-100kmh in 4 sec!!
