Storing sunshine

One technology company has come up with a solar cell which uses sunlight to split water into oxygen and hydrogen fuel. The secret is a thin nano-structured film, which has doubled the cell's efficiency. Metal oxide particles, each just 20-30 nanometres across, provide the vast surface area needed to split water efficiently.

'An array of cells covering a double garage roof could produce enough hydrogen to run a family car for 11,000 miles a year, in Los Angeles light levels.' says David Auty, Chief Executive, Hydrogen Solar
