Green H2 isn't competitive with cheap NG unburdened by CO2 taxes. Realize that global H2 production is enormous -- 75 million tons/year for pure H2, another 24 MT for hydrogen in mixed gas streams -- and much of this needs to be produced even when we're entirely off fossil fuels. Green hydrogen is not an optional thing. So all the problems of making and storing it are going to have to be solved. Once that's done, adding some turbines (very much like existing ones; it's likely possible to just retrofit existing NG turbines with new combustors) is not a large additional step. These turbines already have an after stage that reduces NOx back to N2.
