Cellcius Thermal Battery

The flexible
and sustainable
heat of tomorrow

Heat is a basic need. For heating houses and hot tap water. Heat that we currently obtain largely from gas. That can be done differently.

This heat is already available in the form of industrial residual heat from industry, data centres and horticulture. Heat that could be used to heat more than 3 million homes, without CO2 emissions, without extra windmills or solar fields.

Cellcius Heat Battery Technology makes the utilisation of this waste heat possible. Fast, CO2-neutral and affordable.

Heating without gas

The heat battery technology from Cellcius makes it possible to heat houses, neighbourhoods and offices without the need for a gas connection. This is possible by storing residual heat and using it to heat air and tap water in houses.

Based on salt and water

No explosion or fire hazard, no toxic or unsafe substances. The Cellcius Heat Battery technology works with two simple and safe ingredients: salt and water, or better: a salt hydrate and water vapour. Add these together, a new salt is created and heat is released that can be utilised. In an endlessly repeatable cycle.

Disruptive CO2 reduction

The heat battery itself has no emissions and makes heat that would otherwise be lost valuable. By using residual heat in places where there is heat "left over", houses can be heated without gas. This means an enormous reduction in CO2 emissions, since no extra gas needs to be burned for the heat used.


Because the heat battery makes use of the most common raw materials on earth (water and salt) and uses heat that is already available, the cost per kWh/th is extremely low. 

No heat network required

Because Cellcius Heat Battery Technology does not require an extensive heat network, the technology can be deployed quickly.

Cooling as well as heating

The thermal battery can store heat. This means that, as heat disappears from the air, the battery can also cool air.

Widely deployable

From homes, offices or even entire neighbourhoods. Cellcius Heat Battery is a flexible and future-proof solution for collective heating, which removes the risks and obstacles associated with, for example, heat networks.
The heat battery stores energy in the form of heat in order to make it available again later. In this way, residual heat from industry, for example, becomes easily available for homes and offices.
Cellcius decouples supply and demand of heat and replaces the fixed (underground) infrastructure for heat transport with lossless transport of heat by road, rail or water.
This also means that smaller, remote sources of low-temperature heat can be exploited. This means that even less densely populated areas can be supplied with heat. And thanks to the absence of the need for an extensive heat network, Cellcius Heat Battery technology can be implemented quickly.

Making waste heat valuable

Residual heat is heat that would otherwise go up in the air and thus be worthless. Thanks to Cellcius' Heat Battery Technology, this heat, waste heat, can be made valuable. By using the enormous amount of low temperature heat (waste and renewable heat) for space heating and cooling, large quantities of houses can be heated.

By using this heat, it is possible to reduce CO2 emissions from heating individual houses by 55-100%.

Cellcius Thermal Battery Technology in the news

Heat batteries full of salt could 'take millions of homes off gas'

Tapping residual heat in industry to heat offices and homes later. Dutch scientists have been successful with a so-called heat battery. Crucial ingredient of that battery? Ordinary salt.

With the heat battery technology, we can cool, heat and, of course, store heat. For the industrial and residential environment. The result: we can use energy much more intelligently and reduce peak loads in supply and demand. This is how we change the energy world and accelerate the transition to a more sustainable one.


Storing heat and using it again later:
Let's start an energy revolution!
