A recent study by University of Michigan researchers indicates that small modular reactors achieve better economic viability in industrial applications than in the wholesale electricity market. The analysis evaluated deployment pathways across electricity, process heat, and hydrogen production.

Federal incentives like the Hydrogen Production Tax Credit play a major role in projected profitability for ammonia, steel, and refining sectors. Targeting these heavy industries could drive early manufacturing scale and provide a commercial proof of concept before trying to compete directly with grid power.

A technoeconomic assessment of small modular reactor (SMR) development across the United States suggests stakeholders should shift focus from the power sector to industry, according to a University of Michigan Engineering and School of Environment and Sustainability study published in Nature Communications.

SMRs are compact nuclear reactors built off-site in factories and assembled onsite, providing flexible energy and hydrogen generation with lower capital investment. Dozens of reactor designs are in progress, but none have been built for commercial use, and pathways for early scale-up remain uncertain.

The research team explored potential pathways and formulated a roadmap for commercially viable SMR deployment in the U.S. across electricity, industrial heat and hydrogen applications using site-specific needs. The roadmap evaluates economic performance, decarbonization potential and sensitivity to ballooning capital costs.
