Alleima receives an order for mass production of pre-coated materials for SOFC interconnects from Doosan Fuel Cell

Korea-based Doosan Fuel Cell is targeting both maritime and stationary applications for its fuel cells. Mass production of SOFC will start in 2025 at a new production plant in Korea. Sweden-based Alleima, a global manufacturer of high value-added products in advanced stainless steels and special alloys as well as solutions for industrial heating, will supply Sanergy HT pre-coated material for the interconnects, a key component in the stationary fuel cell.

Interconnects are responsible for connecting individual cells in a fuel cell stack and ensuring that the stack functions as a cohesive unit. Primary roles and functions of interconnects in SOFCs include electrical conduction; separation of gases; structural support; thermal management; and minimization of leakage. Interconnects are exposed to high temperatures and reactive environments. They must resist oxidation, corrosion, and other forms of degradation while maintaining performance over time.

A Solid Oxide Fuel Cell (SOFC) operates at high temperatures, ranging from 500-700 °C and, due to its high efficiency, is gaining increasing interest as an important enabler for the shift to a sustainable energy system due to its high efficiency. Examples of use include providing primary and backup electrical power for data centers and buildings, as well as serving as an auxiliary power supply on ships to support maritime transport’s efforts to reduce CO2 emissions.

The Alleima order spans over two years and the deliveries will start in the first quarter of 2025. The total value of the order value amounts to SEK 160 million (US$14.6 million).

Separately, Alleima received an order for steam generator tubes for NuScale small modular reactors. The order, placed by the Korean nuclear fabricator Doosan Enerbility, one of the major suppliers of nuclear-power-related facilities in the world, is for approximately 200 kilometers of steam generator tubes. The end-user of the steam generator tubes is NuScale Power. It was booked in the first quarter of 2025 and reported in the Tube division.

NuScale’s SMR is based on proven pressurized water-cooled reactor technology where Alleima’s current steam generator tubing alloys are used.
