Germany's largest utility, RWE, has entered a substantial 15-year agreement with France's TotalEnergies to supply green hydrogen starting in 2030. RWE will provide around 30,000 metric tons of green hydrogen annually to TotalEnergies' Leuna refinery in Germany to aid in reducing the plant's carbon emissions. This deal marks a significant milestone as the largest quantity of climate-neutral hydrogen ever contracted from an electrolyzer in Germany. The green hydrogen will be produced at RWE's 300-megawatt electrolysis plant in Lingen, western Germany, with TotalEnergies' Leuna refinery becoming a key customer. Additionally, TotalEnergies and Air Liquide are investing over $1 billion in two large electrolyzer projects in the Netherlands to further green hydrogen production. These initiatives align with TotalEnergies' ambition to mitigate emissions from its refineries in Europe. Despite challenges, such as cost competitiveness with gray hydrogen, the commitment to green hydrogen underscores the partners' focus on sustainability and climate objectives.
