SEEKING A UKRAINIAN HOST PARTNER
Turn fleeting sunshine to durable heat.
Help co-ordinate the effort to build a pilot thermal storage plant. Dirt-cheap, resilient to attack, and able to recharge off-grid.
Help identify a host ↗Target: winter 2026–27 · We need your help!
How it works
Electricity is gathered from the grid or from the on-site solar panels 
Intermittent power is used to pump heated air into an earthen core. Storage can accumulate seasonally 
When needed, heated air is cycled into an existing central heating facility, generating thermal stability.
01 / START SMALL
Demonstration of concept.
The ideal site for Blue Khata:
- An undeveloped site of approx. 0.5 acres near urban dwellings with central heating.
- Desire to supplement grid-supplied heat.
- An opportunity to prove the concept for wider deployment.
Solar array
Earthen Storage
2,000–4,000 m² near the heat user
Build for the future
The potential for uninterrupted heat.
While the pilot site cannot replace existing grid supply, a working demonstration would pave the way for a future of uninterrupted heat. Earthen thermal storage powered by intermittent solar is cheap to install, maintain, and resilient to attacks to itself and the wider grid.
Help secure a future of winter independence in Ukraine.
What would a whole winter require?
Illustration: 200 m² × 170–250 kWh/m² per heating season = 34–50 MWh of space heat, before network losses. This is a broad building-stock benchmark, not a warming-centre design.
Seasonal operation needs a larger store, a local solar-production model, verified months-long heat retention, and sufficient heat output on the coldest days. Charging must begin before winter. Final capacity and land area remain open.
THE NEXT STEP
Know a community
that could host this?
We are looking for an interested local point-of-contact in Ukraine to discuss implementing this novel solution.
