Geothermal project DEEEP: groundbreaking heat supply for Vienna

An important project has started in Vienna: The Geothermia project "Deepeep", a collaboration between Vienna Energie and OMV, is now in the implementation phase. This initiative should not only diversify the city's energy supply, but also make an important contribution to the use of renewable energy sources.

The drilling space is currently being prepared in the city as Aspern. In the coming weeks, an impressive 50 meter high drilling tower will be built with the aim of starting with the depth holes in winter. The planned holes will lead up to 3,400 meters into the ground and should be completed by mid -2025. According to the OMV expert Bernhard Novotny, the system will be able to provide district heating for around 20,000 households in Vienna from 2028.

planned holes and possible tests

The project initially provides for three holes. If it turns out that the holes are successful, formation water is pumped up from the deep layers. These water samples are examined, among other things, to understand the chemical composition of the collected water. After the first holes and tests, the team plans to start building the upper parage in 2026.

The planned system will achieve an impressive output of 20 megawatts and pump hot water over 100 degrees on the surface. After going through a heat exchanger to gain energy, the cooled water is led back to the geothermal reservoir via an injection bore, where it is warmed up again. The entire process runs in a closed circulatory system, which further increases the efficiency of the plus to energy.

expanded plans for the future

Wien Energie and OMV have ambitious plans that go beyond drilling. In the future, a total of several plants will be developed that could achieve a total capacity of around 200 megawatts. This could supply up to 200,000 households with environmentally friendly district heating. Up to seven deep geriatric facilities in Vienna are planned, which not only ensure environmentally friendly energy supply, but will also play an important role in the fight against climate change.

The financing of this project is not only carried out by private funds, but is also supported by public bodies, including the Ministry of Climate Protection and the climate and energy fund. It is a step in the right direction to promote sustainable energy sources and reduce the dependence on fossil fuels.
