HoCoSto offers solution to connection problems in relation to grid congestion

Do you want to heat or cool your building without gas but your connection is too small and reinforcement is not possible? Or are you not getting a new (major) connection for your new construction plans?

Thermal energy storage

HoCoSto develops, produces and realizes underground heat and cold storage for large consumers of energy. We provide standard configurable solutions including smart power management as well as storage-only for third-party systems. By storing energy from renewable sources underground, we make sustainable heating and cooling possible.

Flexible energy system

Using a HoCoSto storage creates flexibility in the energy system. The moment when heat is needed and used (demand) is decoupled from the moment when renewable heat is available (supply).

The HoCoSto storage has a unique support structure that eliminates the need for walls and makes the topsoil usable again as a parking lot or sports and playing field. Storage varies between 500 m3 and 3000 m3.
