NuScale Power (NYSE: SMR) has partnered with GSE Solutions to develop a hydrogen fuel cell generation and storage plant simulation model using GSE's JTopmeret modeling technology. The simulation supports NuScale's research initiatives for integrated energy systems focused on clean water and hydrogen production.

The collaboration resulted in redesigning steam supply, hydrogen compression, and heat recovery system control logic for NuScale's reversible solid oxide fuel cell (RSOFC), which interfaces with their existing SMR control room simulator in Corvallis, Oregon. The enhanced simulator can evaluate configurations for industrial applications requiring over 200 metric tons of hydrogen per day. Notably, NuScale becomes the first SMR company to integrate hydrogen production into its control room simulator.

Insights

NuScale becomes first SMR company to integrate hydrogen production simulation, advancing nuclear-hydrogen capabilities with GSE's modeling technology.

This collaboration between GSE Solutions and NuScale Power marks a technological milestone in the nuclear-hydrogen integration landscape. NuScale has become the first SMR company to integrate hydrogen production into its control room simulator, a significant step in evaluating how small modular reactors can support hydrogen economies.

The simulation platform, developed using GSE's JTopmeret® and JLogic modeling technology, enables NuScale to test and optimize their reversible solid oxide fuel cell (RSOFC) system that interfaces with their existing SMR simulator. This capability allows for dynamic evaluation of configurations capable of producing over 200 metric tons of hydrogen daily - substantial capacity aimed at commercial-scale industrial applications.

From a technical perspective, this simulation environment creates a valuable testbed for control strategies without the costs and risks of physical implementation. High-Temperature Steam Electrolysis, the method being simulated, offers efficiency advantages over conventional hydrogen production techniques. The integration with hydrogen storage systems further enhances the potential flexibility of NuScale's technology, potentially allowing their SMRs to operate in varying modes depending on energy demands.

This development demonstrates NuScale's forward-thinking approach to expanding SMR applications beyond traditional electricity generation into the growing hydrogen production sector. By creating this simulation capability, NuScale positions itself at the forefront of companies exploring how nuclear energy can support decarbonization through clean hydrogen production.

COLUMBIA, Md., June 30, 2025 /PRNewswire/ -- GSE Solutions, a leader in advanced engineering solutions supporting clean energy production and decarbonization initiatives in the power industry, today announced it has developed a hydrogen fuel cell generation and storage plant simulation model using its JTopmeret modeling to support a NuScale Power (NuScale) (NYSE: SMR) hydrogen simulator project.

NuScale, the industry-leading provider of proprietary and innovative advanced small modular reactor (SMR) nuclear technology, recently launched new research initiatives aimed at advancing integrated energy systems that can deliver both clean water and energy-efficient hydrogen production. Included was the development of an Integrated Energy System simulator for hydrogen production (High-Temperature Steam Electrolysis Mode), hydrogen fuel cell generation and hydrogen storage.

GSE Solutions, in collaboration with NuScale's operations team, helped redesign the steam supply, hydrogen compression, and heat recovery system control logic, utilizing GSE's JTopmeret® and JLogic modeling technology, components of GSE's JADE® high-fidelity simulation suite, for their reversible solid oxide fuel cell (RSOFC). The RSOFC interfaces with the existing SMR control room simulator at NuScale headquarters in Corvallis, Oregon. The updated simulator enables NuScale to dynamically evaluate and optimize various configurations for a wide range of commercial-scale industrial applications that require more than 200 metric tons of hydrogen per day. NuScale is the first SMR company to integrate hydrogen production into its control room simulator.

"We are proud to be part of an industry first," said Ravi Khanna, President and CEO, GSE Solutions, "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 decarbonization goals."
