- Q: Is this proven?
- A: Yes, it combines standard HDD and heat pump technology, using clay’s natural thermal properties.
- Q: How deep and long are installations?
- A: 5 – 26m depth, 200 – 800m per stack, scalable based on demand.
- Q: Would a warmer underground clay condition increase the Heat Pump Coefficient of Performance (COP)?
- A: Yes it would, typical clay temperatures from 10-18°C can have COP of ~3.5. Clay temperatures from 20-25°C can have COP~4, and above 25°C can have a COP of 4.5 and above.
- Q: How does CHRS compare to GSHP or Solar Farms?
- A: Higher reliability, no weather dependency, land usage minimal, advanced heat cycling technology, and lower OPEX with longer lifespan.
- Q: How much energy can it generate?
- A: 0.7 – 4 GWh/yr per stack depending on length and stacks.
- Q: How can you be sure this system works – is it proven?
- A: CHRS combines two proven ideas, first, the heat network system, closed-loop district heating, has been used successfully across Scandinavia and Europe for over fifty years, supplying reliable heat and hot water every day. Secondly, CHRS uses the thermal energy stored in clay underground, whose temperature stays stable all year round. So while our energy source is new, everything else about the system is completely proven technology used worldwide. We just changed the input.
“CHRS isn’t just another renewable, it’s an invisible energy infrastructure that could quietly support communities for the next century, all while it can reduce reliance on gas, outperform air source heat pumps, and power heating networks without consuming land or creating eyesores.”
