British Petroleum abandon green (blue hydrogen)plant in UK.
We all know it takes a hell of a lot of energy to split hydrogen into its pure form. Or you use dirty hydrogen from methane steam reforming.
Ed is not going to be happy
You don't know much about this or how to use Google do you.
Green hydrogen is produced via electrolysis. It's not very efficient compared to using the electricity directly, but this isn't a problem if there is an excess of green energy available. For large-scale production, there isn't, so it's a problem. However potentially less of a problem for some applications than fossil fuel use.
Blue hydrogen is produced by steam reforming fossil fuels, combined with CCS - with the CCS part being Ed Bendytoy's pet project. I personally think it is a technological dead end.
In neither case is hydrogen "split".
