For example, the company selected Cummins (CMI -1.72%) to supply a 100-megawatt proton exchange membrane electrolyzer for its largest project (Lingen) in Germany. It could produce as much as 11,000 tons of green hydrogen annually once commissioned in 2027.
The company plans to build H2Teesside, which would be one of the largest blue hydrogen facilities in the U.K. However, it canceled its HyGreen Teesside project, which was the first planned green hydrogen project in the U.K. In Australia, it exited a planned green hydrogen production facility in July 2025. These project cancellations show that while hydrogen has a lot of promise, it faces many obstacles in becoming a commercially viable fuel.
