And even green hydrogen isn’t as carbon neutral as one would think if it is produced using renewable energy that otherwise could have fed a non-100% green grid. Because in that case there is demand that needs to be met with fossil fuels — you might as well have just used fossil fuels to make the hydrogen and had the same carbon footprint. The only way green hydrogen is really green is if it is using renewable power that would otherwise have been dumped.
