GeoHex Project Nearing Completion

Tue, 21 March, 2023

Following over three years of work, the Horizon2020-funded GeoHex project is now nearing cvompletion with the consortium now working on the final results and tests.

The project consortium, which consists of 13 partners from across Europe and the Philippines, have been drawing on their technology transfer expertise since 2019 to optimise heat exchangers for geothermal energy production.

Optimising geothermal heat exchangers will reduce both the initial and ongoing operating costs and also improve the overall efficiency of geothermal plants.

The harsh environments associated with geothermal energy mean that components constantly under threat of corrosion and scaling, which results in high capital, operational and maintenance costs.

Because heat exchangers, whether direct or organic rankine cycle, bear the brunt of these harsh conditions, the GeoHex project has been working to deliver improved anti-scaling and anti-corrosion properties as well as improved heat transfer performance. This will, in turn, lead to more efficient and cost-effective systems and encourage the increased use of geothermal power as a means of stabilising grid fluctuations and delivering a reliable, renewable energy resource.


The GEOHEX project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 851917
