Bloom Energy is partnering with Shell to study decarbonization solutions, utilizing Bloom’s proprietary hydrogen electrolyzer technology, according to a March 6 press release.

The companies will collaborate with the goal of developing large-scale, solid oxide electrolyzer (SOEC) systems that would produce clean hydrogen for potential use at Shell’s assets.

Bloom’s SOEC technology can augment or replace existing fossil fuel-powered grey hydrogen supplies.

Grey hydrogen is produced at refineries by high CO2-emitting steam methane reformation—a process where high-temperature steam is used to produce hydrogen from a methane source. Clean or green hydrogen is produced from water electrolysis, using renewable energy, the release said.

“This technology could represent a potentially transformative moment for opportunities to decarbonize several hard to abate industry sectors,” said KR Sridhar, founder, chairman and CEO of Bloom Energy.

Bloom has also staged its 4-MW solid oxide electrolyzer, where it produced 2.4 metric tons of hydrogen per day at the NASA Ames research facility in Mountain View, California. The project is expected to commence in May.
