splitting of water to store solar energy

Splitting of water to store solar energy: 

Splitting of water to store solar energy OBJECTIVE Finding out an inexpensive way to store the sun’s energy for those times when the sun isn’t shining.

Slide 3: 

Duplication of Photosynthesis: A way to Produce CLEAN fuel HYDROGEN Capture the charges with Water Splitting CATALYSTS 2H2O 2H2 + O2 Storage of solar energy in the chemical bond of H2 and O2 Anode: Holes are captured by a catalyst to produce O2 2H2O O2 + 4H+ + 4e- Cathode: Electrons are captured by catalyst to produce H2 4H + + 4e- 2H2

Slide 4: 

SCHMATIC FOR HYDROGEN PRODUCTION SETUP Precursor: Cobalt Nitrate hexahydrate (Co (NO3)2, 6H2O) Potassium dihydrogen phosphate (KH2PO4 )

Slide 5: 

USAGE OF HYDROGEN

Slide 6: 

FUEL CELL Generates power from hydrogen as fuel Overall reaction: 2 H2(gas) + O2(gas) → 2 H2O + energy CONCLUSION It’s an inexpensive method to harness solar energy. It’s a process under research. In coming years all our electric wires were replaced by solar energy if this technology is commercially available BIBLIOGRAPHY http://www.renewable-energy-sources.com/2008/12/03/hydrogen-production-using-photoelectrochemical-water-splitting/ www.iith.ac.in/.../Clean%20Fuel%20from%20 water -Group%2012_Dr.Deb .. http://www.technologyreview.in/energy/21536/
