While many are hoping that hydrogen will one day replace fossil fuels as a primary source of energy, producing it cheaply remains a major obstacle. But according to a recent article in the New York Times, researchers at a national laboratory in Idaho and a ceramics company in Utah have found a way to produce hydrogen using far less energy than other methods. The process involves a new kind of nuclear reactor that can run electricity through water at a very high temperature, and use a ceramic sieve to separate the oxygen from the hydrogen. Such a reactor could not only produce electricity for the grid, but also enough hydrogen to equal two and a half gallons of gasoline per second.
