Isn’t “green hydrogen” a sham? I thought the production of it wasn’t actually very CO2 friendly and comes out of fossils fuels themselves?

- klyrs 5y agoWell there's "blue hydrogen" and "brown hydrogen" which are produced from natural gas and coal respectively. Green hydrogen is produced through electrolysis, from renewable energy sources like hydro, wind and solar.

Terminology correction: From low-carbon energy sources, like wind, solar, nuclear and hydro. https://en.wikipedia.org/wiki/Green_hydrogen https://en.wikipedia.org/wiki/Green_hydrogen

- jhgb 5y agoGreen hydrogen isn't; the thing you're thinking of isn't called green hydrogen.
- cjblomqvist 5y agoThis particular steel is made to be 100% CO2 neutral (as is all hydrogen in Sweden). Very much most likely made from hydro power (accounts for about 40% of power generation in Sweden - and the owner of most hydro in Sweden, "Waterfall", which is state owned, is a partner in the project) of from wind. Both energy sources is very common in the north of Sweden.
