Therefore, it must be first generated (e.g., by electrolysis of water), then stored, to be finally used — ideally in fuel cells transforming chemical energy directly into electrical one.
This process could form the basis of a practical solar - energy storage system, Nocera says, in which electric current from a solar cell passes through water to the catalyst, breaking the water into oxygen and hydrogen through electrolysis.
If you do hydrogen evolution, producing hydrogen from water, that's water electrolysis, which produces clean hydrogen for fuel cells and other applications.»
An M.I.T. researcher thinks he's found a way to efficiently use solar power to drive the electrolysis of water, which would isolate hydrogen for fuel cells.
These include electrolysis, which uses electricity to split water into hydrogen and oxygen, and photoelectrochemical (PEC) cells, which use sunlight to do the same thing.
Producing hydrogen and oxygen by the electrolysis of water (the hydrogen could later be used to power clean fuel - cell vehicles, oxygen has many uses);
Solid oxide electrolysis cell (SOEC) has the potential to be cost - effective, environmentally friendly, and highly efficient for the production of hydrogen from water.
That said, there are seductive small - scale options emerging, like the Fronius Energy Cell system in which any excess electricity from a PV cell used to decompose water into oxygen and hydrogen by electrolyCell system in which any excess electricity from a PV cell used to decompose water into oxygen and hydrogen by electrolycell used to decompose water into oxygen and hydrogen by electrolysis.
