"Blue hydrogen" is commonly used for hydrogen produced from natural gas. If it is produced by steam reforming (most common), then the associated CO2 emissions are worse than if you just burn the natural gas directly.

"Green hydrogen" is usually hydrogen produced from water by electrolysis, using electricity from non-CO2 source, e.g. wind or electricity.

Blue hydrogen is supposed to capture the carbon. If its just emitted, then it's grey hydrogen: https://www.nationalgrid.com/stories/energy-explained/hydrog...

Right, if you "oops" don't have working capture because it's never been practical you're making "Blue" hydrogen in which your customers can tell everybody they're environmentally friendly but due to a technical hitch you are emitting lots of CO2. Maybe you can agree a token $1B fine, of course offset against the taxes you were already going to pay, and everybody carries on as before. Hooray for your profitable corporation and oops, too bad for the stupid humans who live on the gradually less inhabitable planet you're destroying.

This would only be really dumb if the corporation was owned by humans. Huh.

1bi fine? i wish. they just sign up for those carbon buyback scams and won't cost more than 20mi, including the bribes.

You are entirely correct.
