Problem
Urban district heating systems rely heavily on fossil fuels or biomass, resulting in high carbon emissions, volatile fuel costs, and large physical footprints that strain city space and infrastructure.
Solution
Steady Energy designs, builds, and operates compact low‑temperature, low‑pressure nuclear reactors (the LDR‑50) that generate up to 50 MW of zero‑carbon thermal power per module. The reactors are modular, can be installed underground, and connect directly to existing district‑heating networks, delivering nearly 100 % of the produced heat without turbines or generators. By operating at pressures comparable to household appliances, the system simplifies safety management and reduces construction costs. Multiple modules can be paralleled to meet the heating demand of a medium‑sized city, while also providing process heat for industry, desalination, or other low‑temperature applications.
Target Audience
Primary customers are municipal utilities and city planners seeking carbon‑free district heating, as well as industrial operators that require reliable low‑temperature heat for processes such as food production, brewing, textiles, or desalination.
Features
- 50 MW thermal output per LDR‑50 module with refueling cycles of 2–3 years
- Low‑temperature, low‑pressure reactor design enabling underground, footprint‑free installation
- Direct heat delivery to district‑heating grids with ~100 % thermal efficiency (no turbine losses)
- Modular architecture allowing parallel configuration to scale capacity to city‑wide needs
- Physically separated water circuits and sealed reactor pool to contain any leaks within the module
- Capability to supply process steam for industrial users and waste heat for desalination plants
