EIB providing €45M loan for Eavor’s innovative geothermal technology in Bavaria

The first commercial-scale Eavor-LoopTM is being built with the additional support of a €91.6 million grant from the EU Innovation Fund.

The European Investment Bank (EIB) is providing a loan of close to €45 million for an innovative geothermal heating project Eavor-LoopTM in the German state of Bavaria.  Canada-based Eavor will implement its closed loop geothermal technology for the first time at commercial scale in the Bavarian town of Geretsried. In contrast to conventional geothermal heating, the Eavor-LoopTM technology does not capture heat from subsurface water or steam reservoirs. Instead, the company drills deeply into the earth and harvests the heat directly from underground rocks.

The first commercial-scale Eavor-LoopTM is being built with the additional support of a €91.6 million grant from the EU Innovation Fund. The EIB loan comes with a guarantee by the European InvestEU-programme. The project is co-financed by Japan Bank for International Cooperation (JBIC), ING Bank N.V. (ING) and Mizuho Bank, Ltd. (Mizuho) and is insured by Japan's Export Credit Agency, Nippon Export and Investment Insurance (NEXI). It qualifies as a green loan in accordance with the Loan Market Association’s Green Loan Principles. The combined support from the EIB, JBIC, ING and Mizuho amounts to €130 million. Green Giraffe Advisory acted as the sole financial advisor to the Borrower to structure the debt financing package.

The Eavor-LoopTM system resembles a giant underground radiator. Two vertical wells are drilled to a depth of 4 500 to 5 000 metres. Then 12 pairs of horizontal laterals, 3 000 to 3 500 metres long, are drilled from the bases of each of the two wells, for a total of about 90 kilometres of drilling (about 320 to 360 kilometres for four loops). The giant radiator is then filled with fluid.

The system operates naturally on a thermosiphon. The water in the bottom part of the system is heated by the underground rock and naturally rises to the surface where it can be used directly for district heating or to generate power.

The system emits fewer greenhouse gases than conventional geothermal systems because there is no need to reinject new fluids and it does not require the extensive use of pumps. To operate this system, a specific kind of subsurface rock is needed to use the thermal conductivity.

Before starting the commercial Eavor-LoopTM in Germany, Eavor built a pilot, the Eavor-Lite, in Alberta, Canada, in 2019. The pilot has been in operation for the past five years.

Eavor’s total investment is expected to reach €350 million. The Eavor-LoopTM will provide heating to households and businesses. In addition, a power station on site will convert the geothermal heat to electricity. Eavor has already signed an offtake contract with the local heat-provider and intends to start heat delivery in 2026, increasing the supply stepwise. Eavor-LoopTM has started developing a second project in Germany to supply 15-20% of the demand for district heating in Hanover in the German state of Lower Saxony.

Nicola Beer, EIB Vice-President with oversight of financing in Germany, said, “In addition to wind- and solar-energy, geothermal heat provides a natural, steady and reliable source of clean renewable energy. The Eavor-LoopTM therefore supports the transition to a carbon-neutral energy system in Germany and helps the country to get independent from fossil fuels, while adding to energy security for the people and businesses.”  

Commissioner for Climate Action, Wopke Hoekstra, said, “Once again, we see how valuable the work of the Innovation Fund is through the funding it provides for cutting edge projects that lower emissions. Today, thanks to €45 million investment by the European Investment Bank and €91.6 million from the Innovation Fund, we are supporting the innovative geothermal technology Eavor-LoopTM in Bavaria, Germany. This project will provide low-carbon heating to thousands of households and businesses. It is an example of the role the geothermal industry will play on the road to net-zero. Switching from fossil fuels to geothermal energy can help decarbonise the EU population’s energy needs and reduce our energy bills.”

Daniel Mölk, Executive Vice President Europe Operations, emphasised, “We are impressed and honoured that, after the EU Innovation Fund, the European Investment Bank is now also co-financing our project in Geretsried. Europe has recognised that the Eavor-LoopTM is a scalable key technology for achieving climate neutrality and significantly more energy security on this continent."
