Highlights Higher methane emissions from blue H2 production CO2 emissions only 12% less than for grey H2 Casts doubt on climate viability of blue H2 Burning low-carbon hydrogen for heating is significantly worse for the environment than using natural gas or diesel, a scientific study published Aug. 12 has found.  Full life cycle greenhouse gas emissions from burning blue hydrogen for heating were more than 20% greater than using conventional natural gas, the report from researchers at Cornell and Stanford Universities said. Blue hydrogen production, via steam methane reforming of natural gas with carbon capture and storage, also had higher fugitive methane emissions than conventional ‘grey’ hydrogen from fossil fuels because of increased natural gas use in powering the carbon capture operation, the study published in Energy Science & Engineering found. Even with CCS, CO2 emissions from […]
