CHRS Energy's clay heat recovery system uses subsurface clay formations to capture and store thermal energy using closed-loop ground arrays and proprietary thermal transfer fluid.
About
CHRS Energy's clay heat recovery system is a breakthrough in renewable thermal energy, harnessing the untapped potential of clay-rich strata as an energy store. By combining advanced ground engineering, precision borehole arrays, and a proprietary thermal transfer fluid, CHRS captures, stores, and delivers stable low-carbon heat year-round.This approach transforms clay-rich geology from an overlooked asset into a scalable, high-efficiency energy infrastructure. The system's modular design makes it adaptable to urban districts, airports, Medical estates, manufacturing facilities, and national-scale infrastructure projects.
Key Benefits
CHRS delivers a stable, all-season thermal output that avoids intermittency issues of wind and solar. Its operating principle is based on consistent underground clay temperatures, which ensures predictable performance and efficiency year-round. The proprietary thermal transfer fluid maximises heat exchange while remaining non-toxic and environmentally safe. Installation is trenchless, enabling deployment in dense urban areas and integration into existing infrastructure. CHRS significantly reduces energy costs, carbon emissions, and dependency on fossil fuels while providing long-term, dependable energy security. CHRS can also cool, or remove the heat from the clay-rich substructure in heatwaves, i.e. underground tunnels, subways.
Applications
CHRS is suitable for district heating schemes, hospitals, universities, manufacturing plants, airports, data centres, and residential developments. It operates continuously, providing base-load heating or cooling. Its year-round stability makes it ideal for large-scale infrastructure, industrial operations, and municipal networks seeking to decarbonise heat supply.
