Nuvora Energy has completed a pre-feasibility study for a 300 MWth prismatic high-temperature gas-cooled reactor integrated with a hydrogen production facility based on solid oxide electrolysis. The independent review, carried out by DBD International, assessed the project across three dimensions — technology, licensing pathway, and commercial viability — and was issued on May 20, 2026.
At the heart of the system is a prismatic HTGR (High Temperature Gas-Cooled Reactor) operating at significantly higher temperatures than conventional water-cooled reactors. This makes it suitable not only for electricity generation but also for supplying high-grade process heat to industrial applications. Coupling with a SOEC — Solid Oxide Electrolysis Cell — leverages both electricity and high-temperature steam to produce hydrogen at efficiencies well above conventional electrolysis. In this configuration, the high-temperature steam is not a byproduct: it is an integral part of the process.
The platform is designed with operational flexibility in mind. It can pivot toward electricity or hydrogen production depending on market conditions and customer needs. Nuvora describes this as a central pillar of its commercial strategy: keeping options open until the market signals the most advantageous direction. Potential co-products such as industrial heat and oxygen remain subject to further engineering and site selection work.
The pre-feasibility study, issued as revision R01 in May 2026 under the title 300 MWth High Temperature Gas Cooled Reactor for Integrated Power and Hydrogen Generation, was accompanied by DBD International’s parallel independent review, commissioned directly by Nuvora to provide a structured external assessment. This does not constitute construction approval: it marks the close of the exploratory phase and the opening of full feasibility work, which will bring in site selection, supply agreements, and specific regulatory requirements.
Nuclear hydrogen — often referred to as pink hydrogen — is attracting growing attention precisely because high-temperature reactors offer a production pathway that is not subject to the variability of renewables. An HTGR operates continuously, delivers stable heat output, and lends itself to integration with heavy chemical and industrial facilities. The demand for clean hydrogen to decarbonize steel, ammonia, and refining is real and quantifiable. Nuvora is targeting this market with a model that keeps power generation and hydrogen production structurally separate, activating the latter only when economically advantageous.
The next milestone is the full feasibility study. If the numbers hold up through that phase, the project can advance to concrete site selection and the start of regulatory engagement. The commercial HTGR segment has yet to produce a large-scale operating plant in the Western world, and whoever secures a license first will have established a position that will be very difficult to challenge.
