How will green and blue hydrogen compete with natural gas and with each other? New paper that combines ranges for direct cost developments and residual emissions. Importantly, CO2 & methane pricing or emission regulation will have an increasing impact authors.elsevier.com/c/1iMSj925JE... 1/9

Key insight: Blue hydrogen's residual emissions (CO2 and CH4) can close its competitive window earlier than direct cost parity with green h2 suggests. To compete, blue hydrogen i) needs to be clean (CO2 capture rate >90% and methane leakage rates <1%) and ii)gas prices need to be low (15 €/MWh) 2/9
