  • Alternative location for energy centre in Zurich

    Alternative location for energy centre in Zurich

    The feasibility study conducted by the Swiss Center of Applied Underground Technologies in collaboration with Amberg Engineering AG, Rapp AG and experts from ETH Zurich and Lucerne University of Applied Sciences and Arts has confirmed that there are underground locations in Zurich that are suitable for an energy centre. The focus is particularly on the construction of a cavern beneath the ETH machine laboratory. The disused Latentunnel could be used as an access shaft to ensure access without serious emissions.

    It would also be possible to use the Latvian tunnel as a location for a heat storage facility. According to the HSLU experts, all of CoolCity’s CO2 emissions could be avoided in this way. This would enable the city to achieve its climate targets more effectively than with the Selnau site, where the combustion of gas is planned to compensate for peak loads and excess heat would have to be discharged into the Limmat.

    An underground site also has advantages in terms of rapid realisation and costs. In contrast to the Selnau site, the location under the ETH does not require any permits from the monument protection authorities and minimises the impact on the groundwater. The SCAUT engineers estimate the additional costs for the construction of an energy centre at CHF 15 to 30 million compared to the Selnau substation, plus around CHF 20 million for a heat storage facility. However, this is offset by the advantages of a large above-ground building that can be used for decades, as well as the climatic and environmental benefits of an underground structure.

  • Stäfa receives renewable heating and cooling

    Stäfa receives renewable heating and cooling

    The municipality of Stäfa’s heating and cooling supply is to be modernised with a sustainable energy project. According to a press release, local industry and 500 properties in Stäfa will be supplied with renewable heat from Lake Zurich from 2026. The industrial companies will also receive renewable cooling for their cooling processes from the lake. The project is being realised by Energie 360°. The project aims to save 7,000 tonnes of carbon dioxide in future by replacing gas and oil heating systems. According to the press release, this reduction in emissions corresponds to the consumption of 2.6 million litres of fossil heating oil. Heat is to be generated using heat exchangers in an underground system. Construction of the lake water intake and the underground energy centre will begin in summer 2024. The first pipes for the heating and cooling network will be laid in 2025, and the industrial companies and the first properties will then be connected to the new heating and cooling supply from 2026.

    “Energie 360° has set itself the goal of supplying its customers exclusively with renewable energy by 2040,” Romeo Deplazes, Head of Solutions at Energie 360°, is quoted as saying in the press release. “The Stäfa energy network is a further step in Switzerland’s transformation from fossil to renewable energy.”
