Copenhagen heat storage and energy storage production company

What is Danish Center for energy storage?

Danish Center for Energy Storage, DaCES, is a partnership that covers the entire value chain from research and innovation to industry and export in the field of energy storage and conversion. The ambition of DaCES is to strengthen cooperation, sharing of knowledge and establishment of new partnerships between companies and universities.

How did Copenhagen make a profit?

The income came from 1) a better optimisation of produc-tion in relation to the electricity market, 2) increased production at cheaper units (CHP plants and heat pumps) in the overall heat production system in Copenhagen and 3) increased production at waste incineration plants in the summer.

What is thermal energy storage?

Thermal energy storage comes from storing energy from renewable energies in the form of heat, which in then can be used in district heating systems or be re-converted to electricity through a turbine. The heat can be stored in rocks, water, molten salts, or other phase-changing materials.

How did VEKS pay for pit heat storage?

The pit heat storage was to be charged from VEKS' transmission system and discharged to HTF's distri-bution system. DKK 47.1 million of the total budget came from expenses for pipes, heat exchangers, etc. for connection to the transmission and distribution systems.

When did pit heat storage start?

Construction of the pit heat storage began in spring 2020. Excavation, construction of the inlet and outlet arrangement, installation of the leakage detection system, PP liner and a thin PE liner to protect against dirt, and UV light during water filling proceeded as planned.

Does Arcon Sunmark have a lid solution for pit thermal energy storage?

At the same time, Arcon Sunmark had developed their own lid solution for pit thermal energy storages. The solution differed from the concept proposed in Høje Taastrup in several ways: The lid is modular, built on the same type of liner as proposed in Høje Taastrup. Instead of weight pipes, stones are used to weigh down the center of the modules.
