    Research project focuses on seasonal energy storage

    According to a LinkedIn post, the University of Applied Sciences and Arts of Western Switzerland (HEIG-VD) and the engineering firmPlanairhave launched the BIG4HEAT project. BIG4HEAT will run for two years and is supported by the Swiss Federal Office of Energy (SFOE). Services Industriels de Genève (SIG), Groupe EausGranges-Paccot FR and Cadcime, based in Eclépens VD, are also industrial partners in the project.

    The main objective of the project is to develop an underground seasonal heat storage facility (Chemical Thermal Energy Storage, CTES). The heat energy is to be stored in summer and then used in winter. HEIG-VD and Planair want to use old cisterns for this purpose, which will be converted into heat storage facilities in line with the principles of the circular economy and retrofitting, i.e. the conversion of older facilities. According to HEIG-VD, “seasonal storage could reduce the electricity deficit in winter by almost 20 per cent”. With this project, HEIG-VD and Planair aim to reduce CO2 emissions and create space in urban areas from 2030 onwards by using underground storage facilities.

    Founded in 1956 and based in Yverdon, HEIG-VD conducts research in collaboration with companies, local authorities and national and international partners in various fields such as energy and sustainable development. Planair, based in La Sagne NE, is active in the fields of energy transition and renewable energies.

  • Compact energy storage for sustainable building technology

    Compact energy storage for sustainable building technology

    Cowa Thermal Solutions AG, based in the Technopark Lucerne in Root, has entered into a wholesale partnership with the distribution company Meier Tobler from Schwerzenbach ZH. According to a press release, Cowa intends to use this partnership to significantly expand its market segment in Switzerland. Meier Tobler, a provider of building technology products in the areas of heating, ventilation, air conditioning and sanitation, will distribute Cowa heat storage units for use in single-family homes, apartment blocks and for integration into heat pump and photovoltaic systems. This will make access easier for tradesmen in particular.

    “With Meier Tobler, we have gained Switzerland’s strongest sales partner, who also shares our vision of compact and sustainable heat storage,” said André Waller, CRO of Cowa Thermal Solutions AG, in the press release. “This partnership is a milestone for us. It makes access to future-oriented heat storage easier than ever before, directly where installers order anyway.”

    Cowa plans to launch a new latent heat storage system on the market by the end of 2025. The product for domestic hot water will have a phase change material (PCM) melting point of 48 degrees Celsius and therefore have a high energy efficiency. According to Cowa, the melting point of this “technological world first” would be 10 degrees lower than that of previous systems. Thanks to the low melting point, almost all standard heat pumps can be used for the storage tank.
