Although hydrogen is the most abundant element in the universe, it's a royal pain to make.
Most industrial hydrogen producers currently make the gas by heating methane and water to 815 degrees Celsius and causing a reaction. Unfortunately, this process generates 9.3 kilograms of carbon dioxide for every kilo of hydrogen, so it's not environmentally friendly or cheap.
Other companies like Signa Chemistry have come out with chemical catalysts that can strip hydrogen from water.
Then there is electrolysis, which involves cracking water molecules with electricity. Electrolysis doesn't produce any greenhouse gases or chemical residues so … Read more
