    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.

    Innovative energy technology combines summer surplus with winter warmth

    According to a press release, Matica AG from Wagenhausen and Lucerne University of Applied Sciences and Arts have founded SeasON Energy AG. The aim is to industrialise and commercialise the SeasON sorption heat pump technology, which was jointly developed by the two partners over the past three years. It stores surplus renewable energy in summer using a thermochemical process and provides heating energy in winter with almost no additional electricity.

    “The founding of the spin-off SeasON Energy AG marks another important step in the further development of this pioneering technology and its market launch,” said Matica CEO Marc Lüthi. He will take over the operational management of the Zurich-based green tech start-up.

    “The first pilot plant, which has been in operation for a year at the animal carcass collection point in Frauenfeld, has proven that the technology works,” explains Benjamin Fumey, member of the board of directors of SeasON Energy and head of the CC Thermal Energy Systems and Process Engineering research group at the Institute of Mechanical and Energy Engineering at the Lucerne University of Applied Sciences and Arts – Technology & Architecture.

    A second pilot plant is located at the postal delivery point in Kaltenbach TG and a third in a residential building in the German state of North Rhine-Westphalia. SeasON Energy plans to implement around a dozen further pilot projects over the next 12 to 18 months. The aim is to demonstrate the performance and economic efficiency of the technology.

    In 2025, the SeasON project was awarded the Prix Watt d’OR and the Greenovation Award. SeasON was also one of the three finalists in the Industry Innovation category ofthe Swiss Technology Award.
