Bockris, John O’M.Last Updated on 2013-10-31 01:06:04
John O’M. Bockris, an Australian electrochemist, coined the term “hydrogen economy” in the 1970s. Bockris’ hydrogen economy describes a system in which hydrogen would be used to transport energy from renewable sources over large distances and store it in large amounts. In 1962, Bockris first proposed a plan to supply US cities with solar-derived energy via hydrogen. In 1971, he published the first article on hydrogen in a referred journal. Bockris published Energy: The Solar-Hydrogen Alternative in 1975, one of the first detailed description of what a solar-hydrogen economy would look like.
