NuScale Power along with Shell Global Solutions (Shell) and industry participants will develop and assess a concept for an economically optimized Integrated Energy System for H₂ production using electricity and process heat from a NuScale VOYGR small modular reactor (SMR) power plant. The project entitled, “Development and Demonstration of a Concept for an Economically Optimized IES,” will be completed in two phases. Additional research participants include Idaho National Laboratory, Utah Associated Municipal Power Systems (UAMPS), Fuel Cell Energy, FPoliSolutions and GSE Solutions.

NuScale’s flexible SMR technology holds the potential to balance and stabilize power grids dominated by renewable energies through H₂ production. Energy markets present reliability concerns at times when energy demand is high and renewable energy production is low. In these markets, H₂ would be used as an end-product or as a stored energy source to be processed through a reversible solid oxide fuel cell for electricity generation.

“Hydrogen has been identified as a pathway for global decarbonization and NuScale’s SMR technology complements this goal through low carbon hydrogen production,” said John Hopkins, NuScale Power President and Chief Executive Officer.

A NuScale control room simulator will be modified to evaluate the dynamics of the IES and will include models for the solid oxide electrolysis cell (SOEC) system for H₂ production, in addition to a RSOFC for electricity production. The research will consider the number of NuScale Power Modules needed for use in SOEC H₂ production and the quantity of H₂ stored for subsequent electricity production. Further, local economic factors from the UAMPS Carbon Free Power Project will be assessed, such as the impact in the Western Energy Imbalance Market, resource adequacy programs, and other local market factors to be defined.

“We are pleased to join this collaboration, which is in line with our efforts to explore technologies that have the potential to enable decarbonization and support the energy transition,” said Dirk Smit, Vice President of Research Strategy at Shell.
