NewHydrogen has unveiled its plan to integrate ThermoLoop technology with small modular reactors (SMRs), targeting industrial-scale clean hydrogen production of at least 1 Gigawatt. The announcement, dated July 29, 2026, marks a significant shift in ambition for the California-based company: moving beyond the laboratory phase toward a commercial offering capable of competing in global energy markets.
The principle behind ThermoLoop is straightforward, yet fundamentally different from the prevailing approach. Rather than using electricity to split water — as conventional electrolyzers do — the system harnesses high-temperature heat to drive thermochemical water splitting into hydrogen and oxygen. SMRs produce exactly that kind of heat, continuously and without greenhouse gas emissions during operation. Coupling ThermoLoop to nuclear heat means bypassing grid constraints and the costs associated with large-scale electrolysis plants. According to the company, no existing solution currently delivers the same level of efficiency.
The numbers illustrate the scale of the project. A 50-megawatt SMR paired with ThermoLoop — assuming an energy efficiency of 50% — could produce up to 54 metric tonnes of hydrogen per day. That is enough to supply 54 standard one-tonne distribution stations, supporting 10,000 hydrogen vehicle refueling events every twenty-four hours. SMRs are factory-built, can operate as a single module or in multiple configurations, and individual units can be added or taken offline for maintenance without interrupting overall production. This structural flexibility makes them well suited for distributed industrial installations, without requiring extensive grid infrastructure.
The market context lends further weight to the plan’s ambitions. According to the International Energy Agency’s World Energy Investment 2025 report, global annual investment in energy and infrastructure has already surpassed $3 trillion. The IEA estimates this figure could approach $5 trillion by 2030 under accelerated decarbonization scenarios. NewHydrogen explicitly positions ThermoLoop as a direct response to that demand. CEO Steve Hill stated that achieving true industrial scale for clean hydrogen required looking beyond dependence on the electricity grid, and that SMRs deliver continuous, ultra-high-temperature heat — precisely what the process demands — while eliminating the efficiency losses inherent in electrical conversion.
The path to commercialization follows a defined set of milestones. In May 2026, NewHydrogen announced technical validation of the system and a strategic partnership with NuCube Energy, marking the transition to the engineering phase. By July, automation of the test unit had shifted the focus from manual operation to data analysis, with the goal of accelerating the timeline toward a first commercial pilot plant. If integration with SMRs delivers the expected performance, the model could pave the way for a new category of multi-output energy plants capable of generating electricity and hydrogen in parallel, continuously and without emissions.
