Often said, but questionable if you want to have strict emission standards. The existing "blue h2" projects are abysmally bad, they only capture a small fraction of the emissions produced (see e.g. [1]). That you can run cheap blue H2 with low emissions - both upstream methane and CO2 that isn't captured, because CCS is never 100% - remains to be shown.
