RWE signed an agreement to supply an annual volume of 30,000 metric tons of renewable hydrogen for 15 years to help decarbonize TotalEnergies's Leuna refinery in the German state of Saxony-Anhalt.

Germany's top utility, RWE, said on Wednesday it has agreed to supply French oil major TotalEnergies with about 30,000 tonnes of green hydrogen a year from 2030, in one of the sector's biggest deals.

In a groundbreaking step for the hydrogen market, TotalEnergies and RWE have for the first time agreed on conditions for the purchase of green hydrogen over a period of 15 years. The agreement stipulates that TotalEnergies will purchase around 30,

The agreement is a signal for the German market because fuel suppliers such as refineries are encouraged to gradually reduce their greenhouse gas emissions over time. Using 30,000 metric tons of green hydrogen in a refinery saves 300,000 metric tons of CO 2 per year. That’s how much 140,000 cars emit on average per year.
