The agreement secures a long-term supply of critical secondary-side equipment for Terra Innovatum’s First-of-a-Kind ("FOAK") SOLO™ reactor, targeted for deployment in Illinois by 2027, and supports subsequent Nth-of-a-Kind ("NOAK") global commercialization. Terra Innovatum has already selected its FOAK site at Rock City Admiral Parkway Development in Illinois and has entered into non-binding MOUs for up to 100 SOLO™ units worldwide.

As customer interest accelerates across AI infrastructure, industrial facilities and resilient distributed power applications, securing long-lead equipment and experienced manufacturing partners is becoming an increasingly important competitive differentiator. This agreement represents another step in Terra Innovatum's strategy of establishing the industrial supply chain needed to support commercial deployment at scale.

Through this collaboration, Terra Innovatum and Howden have adapted and optimized Howden’s proven steam turbine technology to meet the specific requirements of the SOLO™ reactor, which is designed as a one‑megawatt‑electric, helium‑cooled micro‑reactor powered by commercially available low‑enriched uranium fuel. The work aligns performance, efficiency, and modular integration to support standardized deployment across sites and leverages Terra Innovatum’s fabless supply chain model, which uses established nuclear manufacturers rather than new in‑house facilities, to accelerate industrialization. In parallel, the companies are defining commercial frameworks, production ramp‑up capacity, lead-time reduction strategies, and modular skid configurations to enable rapid, high-volume rollout of SOLO™ reactors and associated balance‑of‑plant equipment.

The partnership also supports flexible system architectures by integrating multiple SOLO™ units with a common Howden turbine platform to deliver scalable output in the ~3 to 15 MWe range, addressing applications from data centers and industrial facilities to remote mini‑grids. Together, these efforts are intended to shorten deployment timelines and lower lifecycle cost through repeatable, standardized production, supporting Terra Innovatum’s goal of FOAK deployment in 2027 and broader commercialization beginning in 2028.
