Thermal Energy Storage | Local collective heat storage system
Fossil Free & CO2 neutral sustainable and affordable heating and cooling
A HoCoSto thermal energy storage system provides building owners and customers of small-scale collective heat networks with sustainable and affordable heating. The heat is generated by a sustainable energy source: by the sun, wind or residual heat. The excess heat is stored in an underground water buffer, to be used at times when there is no sun, wind or residual heat available.
HoCoSto thermal storage in combination with a local heat network and HoCoSto energy management provides an affordable solution for communities of 40 up to 400 end-users. Consumers pay a monthly fee (fixed cost and the cost of effectively consuming heat) fixed for 20+ years. After all, consumers only pay for the system installation and its maintenance, that harvests free energy.
The storage consists of a simple and patented constructional spaceframe, creating an underground scalable volume filled with water. We store thermal energy in water, subsoil, without functional loss of the surface. The storage can be positioned under sport fields, parking lots, play gardens, etc. (multifunctional use).
Fossil-free and Zero CO2 emission
By using PV or green electricity as auxiliary energy. Balances the electricity grid rather than stressing it (as most fossil free solutions do)
No concrete used
Easy to remove end of lifetime. Fully recyclable, no hybrid materials used
Low carbon footprint in scope 1-2-3
Patented with two European patents, two more in filing process
