The initiative is part of broader research into clean water delivery and efficient hydrogen production technologies.
NuScale, in collaboration with GSE Solutions, has redesigned key elements of its reversible solid oxide fuel cell (RSOFC) system. The partnership utilized GSE’s JTopmeret and JLogic modeling tools from the JADE suite to improve control logic for the steam supply, hydrogen compression, and heat recovery systems.
The resulting simulation model supports both hydrogen generation and storage functions at NuScale’s headquarters in Corvallis, Oregon. The updated simulator is capable of dynamically evaluating and optimizing system configurations to meet industrial-scale hydrogen demands of more than 200 metric tonnes per day.
NuScale has now integrated this advanced hydrogen production capability into its small modular reactor (SMR) energy system. The control room simulator includes features for high-temperature steam electrolysis and hydrogen storage, making NuScale the first SMR company to incorporate hydrogen production into such a simulator.
GSE Solutions President and CEO Ravi Khanna said: “We are proud to be part of an industry first. NuScale can now use the integrated SMR/RSOFC model to test control strategies and determine how best to use them for hydrogen storage in meeting decarbonisation goals.”
The integration of a NuScale Power Module (NPM) with a reverse osmosis desalination system is projected to produce 150 million gallons of clean water per day, without emitting carbon dioxide. When deployed as a 12-module plant, the system can supply enough desalinated water for a city of 2.3 million people and generate electricity for approximately 400,000 homes.
In May 2025, NuScale received design approval for its uprated 250 megawatts thermal (77 megawatts electrical) SMR modules from the U.S. Nuclear Regulatory Commission. This approval supports the company’s ongoing efforts to deliver flexible, clean energy solutions through modular nuclear technology combined with hydrogen and water systems.
The joint project highlights the potential of combining advanced simulation technologies with nuclear and hydrogen innovation to address global energy and water needs in a sustainable and efficient manner.
