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.

A breakdown of today’s c110MTpa global hydrogen market is also provided, looking industry-by-industry, including links to our work on each topic.

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.
