GSE Solutions has developed a hydrogen fuel cell generation and storage plant simulation model to support NuScale Power’s hydrogen simulator project.

The initiative is part of the broader research into clean water delivery and efficient hydrogen production technologies.

In partnership with GSE Solutions, NuScale's operations team has redesigned critical components for its reversible solid oxide fuel cell (RSOFC) system.

Utilising GSE’s JTopmeret and JLogic modelling technology from its JADE suite, they have enhanced the steam supply, hydrogen compression and heat recovery system control logic.

The collaboration has resulted in a sophisticated simulation model that supports both generation and storage at NuScale’s headquarters in Corvallis, Oregon. The updated simulator allows for dynamic evaluation and optimisation of configurations tailored for industrial applications demanding more than 200 metric tonnes of hydrogen per day.

NuScale's small modular reactor (SMR) nuclear technology now includes an integrated energy system simulator focusing on high-temperature steam electrolysis mode alongside the newly developed capabilities. This integration makes NuScale the first SMR company to incorporate hydrogen production into its control room simulator.

GSE Solutions president and CEO Ravi Khanna stated: “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.”

A single NuScale power module (NPM) coupled to a reverse osmosis desalination system is expected to yield 150 million gallons of clean water per day without generating carbon dioxide.

12 NPMs provide desalinated water for a city of 2.3 million residents and electricity for 400,000 homes.

In May 2025, NuScale Power received SMR design approval from the US Nuclear Regulatory Commission for its uprated 250 megawatts thermal (77 megawatts electrical) power modules.
