Cellcius thermal battery

We make sustainable heat available and affordable for everyone, thanks to two everyday ingredients:

salt and water

In the Netherlands, we are rapidly exchanging the traditional high-efficiency boiler for the heat pump. And so we are switching from gas to electricity as the source of central heating and hot water.

Good for sustainability. But also challenging, because our power grid can barely handle the rising demand for electricity.

The solution? Cellcius' heat battery, which transforms a regular heat pump into a veritable thermal power plant. With it, heat can be stored at times when consumption is low and power costs are low. So that heat is available when the heat demand reaches its peak. This saves a lot of money and also 20% of_CO2 emissions.

Secure, compact and scalable.

Supply and demand in balance

Cellcius allows heat to be stored and used days or weeks later. Heat generated by a heat pump earlier when the demand for it was low and the availability of electricity was sufficient. In this way, we create a smart system that balances supply and demand without placing an additional burden on the power grid.

Safe and non-toxic

Cellcius' heat battery takes advantage of salt's unique ability to retain heat. Specially prepared salt is moistened and then dried with hot air. The energy thus stored can be made available again without any loss, even after a long time, by re-humidifying it. Ready for use in existing home and business systems.

Made in Holland

Cellcius' heat plant can be used in conjunction with its own solar panels, making feed-in costs a thing of the past. Or by using energy from the grid at times when the price is favorable. Smart, sustainable and "made in Holland. So every household and property owner can choose a sustainable heating solution with peace of mind.

Scalable solution

Cellcius' technology, after a series of successful test runs, is now ready for real-world applications.

The first product is a 2kW home battery, which can be used in combination with a regular heat pump in moderately insulated (semi-)detached houses with 120 to 160^m2 of living space.

Launching customers will be connected in 2025; market introduction will take place in 2026. From this base, scale up to application in residential complexes, schools and offices based on a 20kW variant of the battery, and eventually to application in larger heat networks.
