Geothermal heat storage utilizes the ground's natural heat capacity, build by using directional drilling is by far the cheapest way to seasonally store heat. Storage is more relevant than ever. It is likely that massive investment in solar, wind and production heat is causing a great need for heat storage.

Heatstorage.dk has developed a unique concept for heat storage. The ground's natural heat capacity is used to store the heat.

The heat storage is established by directional drilling, resulting in less surface damage during construction. It is possible to establish a heat storage under already used perimeters. The surface area can be used freely and the heat storage can even be established underneath buildings or paved areas.

The most significant advantage of the concept is the initial expenditure which amounts to merely 20% of the second cheapest heat storage system currently on the market.

Geothermal heat storage established by directional drilling is the cheapest construction method for seasonal heat storage. Initial expenditure for geothermal storage is from EUR 0.15/ kWh.

Advantages using directional drilling:

•  Causes minimal terrain surface damage

•  The hoses can be placed in the depth ideal to the geological conditions and groundwater

•  Provides best storage surfacearea/ storage volume ratio

•  Can be established underneath constructions and established areas

•  Requires less grout

•  No costs for lids or insulation

•  Boreholes length up to 300 m

•  Flexible design

•  By far the cheapest capital cost
