Hydrogen opportunities: an overview

This data-file provides an overview of eleven different processes for commercial hydrogen production: including their energy-economics, costs and CO2 emissions; plus a qualitative description of their opportunities, challenges and technical readiness.

Covered technologies include steam methane reforming, fossil fuel gasification, pyrolysis, renewable electrolysis, fuel cell electrolysis, solar photoelectrocatalysis and solar photocatalysis.

Our conclusion is that natural gas remains the most viable fuel source on a weighted basis, considering both cost and carbon emissions, It may also be easier to de-carbonise natural gas directly than via the hydrogen route.
