Researchers Discover Efficient Way of Producing Hydrogen ...

“Moreover, hydrogen is not mined or pumped out of the ground like fossil fuels; we have to produce hydrogen. Current hydrogen production methods are expensive and inefficient,” Ryan says. “This, coupled with the lack of existing infrastructure, has hampered the transition from a petroleum economy to a hydrogen economy.
