Fuel cells and hydrogen were the buzz for years in U.S. automotive industry, until foreign competitors began making waves with hybrids.
Problems with the H included the high cost of infrastructure and the fossil-fuel energy needed to make hydrogen stations work.
That could change if new research on enzymes is realized. A team of scientists from Virginia Tech, Oak Ridge National Lab and the University of Georgia has developed a way of producing hydrogen gas by combining enzymes and cellulosic materials from non-food sources with good old water, according to a news release.
