What is Seasonal Thermal Energy Storage?

With seasonal thermal energy storage, heat is captured in solar thermal collectors and transferred to be stored in specialised boreholes in the earth. This charges the earth with heat in the same way you would charge a battery. The summer heat is stored in the earth until winter, when it can be utilised to heat buildings thus recycling the heat. You don’t need to burn oil or gas for heat, therefore, seasonal thermal energy storage dramatically reduces your CO2 emissions.

Heliostorage in Numbers

We have joined the global fight against climate change by developing our seasonal thermal energy storage solution to meet heating demands without polluting the atmosphere. Our installations, from the smallest 80 MWh to the largest 1 GWh, utilise thermal energy in the most efficient way with zero CO2 emissions.

Sustainable Heating and Cooling

In 2020, Europe’s heat production amounted to 599 TWh with 62.1% of that heat coming from fossil fuels, such as oil & gas. Not only is this an issue for our climate, it also contributes to Europe’s energy crisis. Instability and conflict in the region is currently limiting supply of fossil fuels and driving up costs.

Heat pumps are a reasonable alternative to oil and gas as they produce 3 kWh of thermal energy for every 1 kWh of electricity used, however, they are less efficient when it’s cold outside. This is where Heliostorage comes in.

We reduce the amount of time that the heat pump is needed, utilizing the free heat from the sun when suitable. During the colder months, we boost the efficiency of the heat pump by feeding it warm water, allowing the maximum efficiency which can be up to 8 kWh for 1 kWh electricity, resulting in a much lower cost of heating.
