The answers to those questions will likely have a great impact on the speed with which the U.S. economy makes the transition to a zero-carbon future and the cost of getting there. Today about 99% of the hydrogen produced for industrial use – in refineries and manufacturing plants – is so-called “gray” hydrogen.

Creating more environmentally friendly “blue” hydrogen, requires capturing that CO₂ and disposing of it in some manner, such as...read more...
