Hydrogen debate must move beyond colours - WEC

A lack of clarity around the issue could prematurely exclude some technologies, council says in new report

The taxonomy of hydrogen production should move beyond the colours widely used to focus on carbon equivalence, according to a report from the World Energy Council (WEC). The report notes that there seems to be no agreed colour for hydrogen produced from nuclear, and differing shades of blue for hydrogen supplied from various fossil fuels with carbon capture and storage (CCS). A lack of clarity around the issue could prematurely exclude some technological routes that could be more cost- and carbon-effective, according to the report, titled Hydrogen on the Horizon: Ready, Almost Set, Go?. “The focus should be on the carbon intensity of hydrogen and not on the nature of the feedstock” Esp
