Swiss battery storage

Swiss Clean Battery focuses on the stationary fields of application of “home storage” and “industrial buffer”, because the demand and contribution to solving problems in the energy transition is equally great here. An uninterrupted power supply, i.e. the balance between supply and demand, is essential for the power grid as a whole and for industry.

In Kappel, in the canton of Solothurn, we will install one of the largest battery storage systems in Switzerland with a total capacity of 65 megawatt hours. Primeo Energie will use the stand-alone storage system to make energy more flexible and store electricity temporarily and withdraw it again when it is needed.

The Swiss Battery Technology has the potential to mass produce rechargeable batteries using a renewable organic cathode and in the near future. The extensive adoption of Li-ion batteries employed in electric cars and consumer electronics will need order of magnitude more natural resources to a large extent for the automotive industry.

Swiss batteries material are manufactured using low-temperature processes, which saves most of the large amounts of energy used by conventional battery manufacturing. In this way, we are reducing large amounts of the CO2 emission during battery manufacturing.

In this way, the system will help to stabilise the Swiss power grid. With this large-scale storage system, we are making a decisive contribution to the implementation of Switzerland's Energy Strategy 2050, which aims to convert 100 per cent of its energy supply to renewable energies by 2050.

Axpo commissioned its BESS in February this year while utility Thurplus commissioned a 3MW system in September last year. But Switzerland was the location for one of the largest energy storage projects commissioned in recent years, a 20GWh pumped hydro energy storage (PHES) unit which started operations in June 2022 in the Canton of Valais.
