Theme: Hydrogen Fuel
Item #1: The majority of hydrogen is produced by electrolysis from water, and is as clean as the source of electricity used in this process.[6]
Item #2: The global production of hydrogen is more than 70 million metric tons annually (which could theoretically produce 2.3 billon MWh of electricity – US energy production is 4.1 billion MWh annually).[7]
Item #3: Hydrogen is about 2.8 times as energy dense as gasoline by weight.[8]
