Underground Thermal Energy Storage (UTES)

---

• Complete UTES Systems: Feasibility, design, drilling, simulation, and commissioning
• Integration with GSHPs, ORC, ASHP, Solar, CHP, and 5th Generation Heat Networks
• Advanced modelling tools (e.g., TRNSYS, FEFLOW, and GLHEPro) to optimise performance
• Modular BTES fields up to 1 GWh seasonal storage capacity
• Dynamic control systems with real-time weather and demand forecasting
• Low-carbon CAPEX pathway with ESCO delivery models (Design–Build–Operate–Own)
   

• District Energy Systems: Store summer heat from PV or cooling recovery for winter heating
• Data Centres & Supermarkets: Store waste heat to offset heating demand in nearby buildings
• Campus & Mixed-Use Developments: Shared infrastructure, peak shaving, carbon savings
• Industrial Sites: Efficient thermal recovery from waste processes
• Agricultural Applications: Frost protection and off-grid year-round greenhouse climate control
   

• Energy losses <10% over seasonal cycles
• Reversible operation: one field, both heating and cooling
• No aboveground storage tanks required
• Easy integration with smart thermal grids and low-carbon retrofits

• UK Housing Project (2024): 20 BTES boreholes storing 480 MWh of thermal energy, reducing winter heat pump peak loads by 32%.

Grid decarbonisation requires not just clean generation, but also intelligent thermal storage. UTES delivers:

• Load balancing across seasons
• Heat demand shifting
• Enhanced COP for all connected heat pumps
• Decentralised, non-electric load shifting — no need to wait for hydrogen
