Scientists have developed a new way to create hydrogen that eliminates the production of CO₂ emissions entirely. The international team made up of researchers from China and Wales in the United ...

Production of hydrogen varies by method—natural gas reforming/gasification, electrolysis, renewable liquid reforming, fermentation (via biomass)—and these are differentiated by color designation.

Large reserves of white hydrogen may exist within mountain ranges, according to a new study, raising hopes this clean-burning gas can be extracted and supercharge efforts to tackle the climate crisis.
