  • Deep geothermal energy has great potential in Baselland

    Deep geothermal energy has great potential in Baselland

    Deep geothermal energy could potentially supply between 200 and 1800 gigawatt hours of usable heat potential per year in the canton of Basel-Landschaft. This corresponds to between 10 and 100 per cent of future energy requirements for space heating and hot water. This is the conclusion of the study Report on the potential of deep geothermal energy in the canton of Basel-Landschaft. It was commissioned by the Office for Environmental Protection and Energy and is based on Rolf Blatter’s postulate 2022/346.

    According to a press release from the canton, the actual potential depends on various technical and economic conditions and can therefore only be quantified more precisely with further exploration. Because Baselland is one of the most geologically diverse cantons, the number of situations that are suitable for geothermal utilisation is correspondingly large.

    No estimates of the potential of deep geothermal energy in the canton have been available to date. According to the information, the widespread use of near-surface geothermal energy with geothermal probes contributes around 100 gigawatt hours to the environmental heat utilised. With the new CO2 Act, the federal government will promote hydrothermal geothermal energy for heat supply from 1 January 2025.

  • AEW builds heating network in Villmergen industrial estate

    AEW builds heating network in Villmergen industrial estate

    AEW Energie AG has announced its intention to become more efficient in the expansion of renewable thermal energy and is establishing a heating network in the Villmerger industrial area at a cost of CHF 12 million. According to a press release, the municipality granted permission for the building application submitted in April. Construction work is to start in the 4th quarter of the current year. The date for the first delivery of renewable district heating to about 550 single-family homes is set for the 2024/2025 heating period.

    David Gautschi, Head of Production at AEW, has announced that the total heat will save 710,000 cubic metres of natural gas annually, which would cause 1500 tonnes of CO2 emissions.

    According to the information, the heat network uses waste wood as fuel, wood from the region as needed according to ecological cascade use, and solar energy with the help of a photovoltaic system with a peak output of 200 kilowatts.

    The supply unit is to be built between the Bünztalstrasse in the south-west, the municipal boundary in the south-east, the railway line in the north-east and the agricultural zone in the north-west. The heating centre will be built on the Cellpack AG site on Durisolstrasse. The fuels will be supplied via Anglikerstrasse and the Cellpack AG site.

    With this project, the Aargau electricity supplier wants to make a contribution to the Energy Strategy 2050.

  • Comprehensive energy systems by EKZ

    Comprehensive energy systems by EKZ

    The pressure on holistic ecosystems around real estate and their energy solutions is growing. EKZ simplifies this task with clever solutions.

    The combination and central management of electricity generation and storage, heat and cooling generation and electromobility in an integrated energy system leads to the simplification of property management, maximum living and working comfort and optimal energy efficiency in production. In addition, ecological sustainability is ensured.

    The goals of the Energy Strategy 2050 are being built here. Most of the Verdeblu development has been completed and inhabited since autumn 2019. It is noteworthy that this development covers a large proportion of its energy needs itself, and that exclusively from renewable sources.

    "The specifications of the Energy Strategy 2050 are also an opportunity for the real estate industry," explains Dieter Stutz from Atlantis AG, which is active in the areas of environmental consulting, settlement planning and architecture and who developed the project. The heat supply via groundwater was the best and most convincing solution for the area. Atlantis planned and implemented this complex construction project together with EKZ.

    On-site energy production
    The “Grand Chemin” development was built in Epalinges in western Switzerland, with some of the electricity required being produced on site by a photovoltaic system (PV). A new multi-family house is being built in Emmen (LU), which will be characterized by four heat pump systems with groundwater as an energy source and a photovoltaic system with ZEV. Seen in this way, the future of energy has long since begun in this country as well.

  • Riehen receives the green light for geothermal expansion

    Riehen receives the green light for geothermal expansion

    Riehen can continue with its planning for the expansion of another geothermal system. It would increase the number of residents supplied with climate-friendly thermal energy from the current 8,500 to 12,500. The referendum period expired at the end of October. The positive decision from the residents' council is now legally binding. This is now announced by Wärmeverbund Riehen AG ( WVR ).

    In the next step, seismic surveys to explore the subsurface for the geo2riehen project are due in summer 2021. A suitable location for the boreholes is thus sought. If the feasibility of the plant is confirmed, drilling could begin in 2023. They should open up more naturally occurring thermal water for heat utilization.

    An already existing feasibility study confirms that the project has “good prospects for success”. The drilling to promote the thermal water and the construction of the facility will cost around 20 million francs. The costs are shared between the two shareholders, the municipality of Riehen and the Basel energy supplier IWB . The Swiss Federal Office of Energy has promised a grant of 1.2 million francs and has announced a further 5.1 million francs.

    IWB's stake has risen from initially 27 to 50 percent. According to the WVR, this not only makes financing easier. The operation of the systems and the growing supply network can also be better coordinated with IWB: "The gradual and partial shutdown of the gas supply is thus optimally coordinated with the growth of the Riehen heating network."
