At Caldera, we have developed a simple, safe heat storage technology which will allow companies to switch off fossil fuels. We take cheap, green, off peak or on-site electricity and store this as heat in the solid core of our vacuum insulated heat cells, ready to be used when required.

We are based in England and are commercialising a range of products for global impact.

Our industrial product has not yet been launched, and we are exploring both up-front payment and Heat as a Service models.

Caldera has a number of patent and patent-pending innovation on our thermal storage material and insulation system.

Caldera's Storage Boiler will use renewable electricity whenever it is available to provide heat on demand. It can replace fossil fuel boilers in industrial applications to provide hot water, steam, thermal oil or hot air.

The target temperature range is 80-200 celsius.

To be cost-competitive with fossil fuels it is key to have access to cheaper, greener electricity. This can be from on-site solar or wind power, or from the grid with a suitable tariff.
