Climate impact of the development of methane and hydrogen pathways towards 2050 H/F

Subject

Mitigating greenhouse gas emissions at the global scale opens the way to alternative energy carriers, among which two gaseous vectors stand out: methane and hydrogen. A particular attention should be paid to the fact that methane is a potent greenhouse gas about 30 times stronger than CO2 and H2 is also a Short-Lived Climate Forcer about 12 times stronger that CO2 (100-year Global Warming Potential, GWP100-basis). While methane is generally regarded as a transition fuel – lower-carbon than coal or oil at the point of combustion, and able to draw on existing transport and storage infrastructure – the role hydrogen might play over the coming decades remains the subject ...
