How the world can achieve climate goals with clean hydrogen production

February 23, 2024

Driving on hydrogen and using it to heat our homes could be a solution to the climate problem. At least, if we start producing it in the right, clean way. Leiden researchers mapped out the global environmental impact of hydrogen production and looked ahead to 2050. They published their work in Energy & Environmental Science.

With a car running on hydrogen, only water vapor comes out of the exhaust. With a relatively small adjustment, our gas pipelines can also transport hydrogen, so we could use it to heat our homes. The catch: When producing hydrogen, a lot of CO2 is usually released. On average, fourteen kilograms per kilogram of hydrogen.
