BASTET – Czech technology that is changing the way energy is stored
Innovative storage system for preserving thermal energy.
A safer, more accessible, and more sustainable alternative to battery storage.
Energy is not lost. We just don’t know how to store it efficiently.
Growing demand for electricity, price fluctuations, and grid congestion—these are challenges that every energy company and household faces today.
Current solutions, such as battery storage, are expensive, limited in capacity, and often pose a safety risk.
We offer an alternative:
→ We store energy in heat, not chemicals.
→ We use safe and inexpensive materials.
→ We help stabilize the grid and save households money.
BASTET – energy storage for heating and DHW heating
- Up to 270 kWh of thermal energy at 400 °C – high storage capacity for several days of operation without production.
- Patented heat transfer control – precise and immediate power regulation thanks to a separate storage section and exchanger.
- Smart charging – use the cheapest spot electricity or surplus from photovoltaic systems without compromising on comfort.
- Savings of up to 85% compared to electricity – and up to 60% compared to gas for heating and DHW.
- High safety – no risk of fire or degradation, the storage material is stable and durable.
- Easy installation – suitable for standard utility rooms, no special operating requirements.
- Environmentally friendly operation – reduces emissions, increases energy self-sufficiency, and relieves the electrical grid.
