"It's the beginning of a whole suite of possibilities, such as creating a highly efficient fuel, or to trapping atmospheric carbon." Professor Pace said large amounts of hydrogen fuel produced by artificial photosynthesis could transform the economy. "That carbon-free cycle is essentially indefinitely sustainable. Sunlight is extraordinarily abundant, water is everywhere – the raw materials we need to make the fuel. And at the end of the usage cycle it goes back to water," says he.
