US-based First Ammonia has announced a new reservation deal with Topsoe for delivery of solid-oxide electrolysers. Initially, First Ammonia will purchase 500 MW of SOECs from Topsoe’s new manufacturing plant in Herning, Denmark, with the option to expand to 5 GW over the lifetime of the agreement. That initial 500 MW will be deployed over two First Ammonia production projects, both targeting commercial operations in 2025: one in northern Germany, and one in southwest USA.
