The Dual Energy Storage Converter (DESC) is a combined storage of electricity heat and cold which can function as a bulk electricity storage, or as a combined solution for industrial, as well as district heating/cooling applications. During periods of excess electricity generation or low-price electricity availability, a heat pump is operated to charge a hot and a cold storage. In periods of low electricity production or high power prices, DESC can be operated as a heat engine, using the stored temperature difference to generate electricity which can be consumed locally or fed to the grid. Furthermore, DESC can be operated in a thermally open fashion, meaning that heat and cold can be directly extracted from the storages, to cover process heat and cold demand for industries (e.g. pasteurization, product cooling), as well as the space heating and cooling demand in building blocks. HSLU is investigating the DESC technology and applications in the framework of SCCER Storage of Electricity and Heat with the scope of installing a pilot plant in an industrial site in Switzerland by the end of 2020.
