Turn Summer Solar Peaks Into Clean Winter Heat
Solarity Living® stores excess daytime solar in bedrock and delivers efficient winter heating—cutting costs, CO₂, and grid dependence for commercial buildings.
- Cost−30%
- CO₂up to −90%
- Asset value+20%
- Project IRR15%
Why this matters
On-Site Clean Energy, All Year
Commercial buildings in Europe emit over 250 Mt CO₂ annually from heating. Solar peaks in summer when heat demand is low, but it’s scarce in winter when demand is highest.
The solution
Solarity Living®
Seasonal Thermal Storage
Stores summer solar peaks and delivers high winter efficiency—outperforming conventional seasonal storage by 3-4x.
Captures excess (even negative-price) electricity in summer and stores it as heat in bedrock for winter.
- ✓Fixed energy prices and predictable costs
- ✓Turn negative-price electricity into profit
- ✓Up to 90% reduction in CO₂ emissions
- ✓Target project IRR of 15%

How it works
From Solar Peak to Seasonal Heat
A fully optimized energy loop for year-round on-site heating and cooling.
Collect
Capture midday solar peaks when grid prices are lowest.
Store
Store thermal energy in bedrock at optimal temperature.
Generate
Deliver heat and cooling when needed, year-round.
Maximize
Optimize revenue and energy security.
Underground Thermal Storage
Optimized borehole storage preserves thermal energy for months with minimal loss, creating a natural buffer between seasonal production and demand.
