An analysis of the LDR-50 low-temperature nuclear district heating reactor, developed by Steady Energy, indicates that “significant reductions in CO₂ emissions can be achieved by replacing fossil heating fuels with nuclear energy [district heating].” The study, conducted by researchers from the VTT Technical Research Centre of Finland and published in the journal Energies, describes carbon footprint reductions and other environmental benefits derived from the LDR-50, which Steady Energy hopes to introduce in Finnish and other European district heating markets by the 2030s.
