Steady Energy

Steady Energy designs, constructs, and operates compact advanced nuclear heating plants that provide zero-carbon district heating for cities. The company's core technology is the LDR-50 nuclear reactor, which operates at low temperatures and pressures compared to traditional nuclear reactors, ensuring safe and emission-free heat production that can be located near urban areas. The simplified light water nuclear technology focuses solely on heating, offering municipalities an alternative to fossil fuels and biomass without compromising climate targets. Steady Energy's lifecycle emissions are comparable to offshore wind, and the solution complements renewables by decoupling energy-intensive heating demands from the electricity grid during winter months. Roughly 80 million Europeans rely on district heating, with 56% of the EU mix remaining fossil-based. Spun off from VTT in 2024, the company targets commercial plant operation in the 2030s. Founded in 2023 and headquartered in Espoo, Finland, Steady Energy has raised $73.8M in Series C funding from investors including Lifeline Ventures, Yes VC, VTT, 92ventures, LahiTapiola, Tesi, and Move Energy.
