AdvancedHigh-TemperatureGasReactors(HTGRs)

Why It Matters

Decarbonizing heavy industry, which accounts for approximately 30% of global CO2 emissions, requires high-temperature heat sources beyond just electricity. HTGRs can provide this, enabling steel, cement, and chemical plants to operate with zero emissions, and produce green hydrogen at scale, fundamentally altering industrial landscapes. Heavy industry and green hydrogen producers are major winners, while traditional industrial boiler manufacturers and fossil fuel suppliers face disruption. Technical barriers include developing materials capable of withstanding extreme temperatures and neutron fluxes for reactor components, as well as navigating complex licensing processes for novel reactor designs. Commercial deployments are anticipated in the early 2030s, with China, the US, and Japan leading the development race. A significant second-order effect will be the re-industrialization of certain regions, attracting energy-intensive manufacturing back to areas with abundant, cheap, clean process heat.
