German SOFC start-up eyes 250MW factory after $175m capital raise

German start-up Reverion is aiming to build a 250MW factory for its hydrogen-capable reversible solid oxide power plants following a $175m fundraising round.

The firm claims the Series B financing could fund a ten-fold increase in manufacturing capacity for the reversible systems which combine hydrogen production and storage with power generation.

Reverion claims the unit can switch from hydrogen production to energy generation in under a minute, positioning it as a solution for renewable energy storage, industrial sites, and utilities.

With seven operational plants, it also claims a commercial project pipeline exceeding $2bn in revenue potential, while billing demand for the systems as “rapidly expanding.”

In August, Reverion entered a KRW 108.7bn ($76.7m) with Doosan for receipt of an unspecified number of its reversible solid oxide fuel cells (SOFC), which will be supplied in phases through the second half of 2027 and integrated into the power plants.

Doosan’s stacks, based on technology under a 2025 agreement, have been used since last year and, according to Reverion, have consistently achieved electrical efficiency over 74%.

SOFCs are gaining attention in stationary power markets as demand for behind-the-meter generation increases, due to their ability to run on natural gas, biogas, or hydrogen.

Solid oxide electrolysis, however, has faced setbacks, with major electrolyser companies halting plans to commercialise the technology amid low market demand.
