With all the potential solar being installed across rooftops, a place to store the energy collected will be an issue. Using solar, in this case, could be used for separating out hydrogen and stored in these fuel cells. 60% return isn't bad. I wonder how fuel cells stack up against flywheel storage.
If they succeed, we might have a chance to set up every building with its own wind, solar and fuel cell. Such a set up would greatly reduce power outages, pollution and bring technology to those areas too sparsely populated to get it now.
I will definitely follow this research, it may well be the needed key technology we need.
