Study casts doubt on GHG cuts from ‘blue’ hydrogen

Newly released research is casting significant doubt on the greenhouse gas benefits from so-called “blue” hydrogen -- in which carbon capture and storage (CCS) technology is paired with traditional natural gas-based processes to make the fuel -- raising questions about a key decarbonization strategy for several industry sectors. “Far from being low carbon, greenhouse gas emissions from the production of blue hydrogen are quite high, particularly due to the release of fugitive methane,” says the Aug. 12 study from Stanford...
