Photoelectrochemical Water Splitting
Using electricity produced by photovoltaic systems potentially offers the cleanest way to produce hydrogen. Again, water is broken down into hydrogen and oxygen by electrolysis, but the electrical energy is obtained by a photoelectrochemical cell (PEC) process. The system is also named artificial photosynthesis.

Famous quotes containing the words water and/or splitting:
“When peaceful clouds were reflected in the paddies
and the water buffalo stepped surely along terraces,
maybe fathers told their sons old tales.
When bombs smashed those mirrors
there was time only to scream.”
—Denise Levertov (b. 1923)
“I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.”
—Henry David Thoreau (1817–1862)
