Low-GHG Gaseous Fuels Production—H₂, CH₄

Back to Transportation

Most of our transportation is powered by combustion engines and liquid fuels, but it’s also possible to use gases such as hydrogen and methane to power our vehicles. If we can develop new cost effective ways to produce large quantities of low greenhouse gas footprint gaseous fuels at scale, like hydrogen and methane, this would present an opportunity for significant reductions in CO2 emissions from the transportation sector. There are a number of promising technology pathways in this area, with the production of gaseous fuels generally being simpler than the production of liquid fuels. However, significant improvements in the cost and energy-density beyond today’s on-board gas storage technologies will also be required for wide-spread deployment of these fuels across the transportation sector.
