The European Geothermal Council has announced EnBW Energie Baden-Württemberg as the winner of the Ruggero Bertani European Geothermal Innovation Award 2025.
The objective of the EGIA award is to recognise companies that have made outstanding contributions towards the development of the geothermal field in Europe. EnBW Energie was recognised for its pioneering CASCADE project, an innovative approach to lithium extraction from geothermal brines. The project stood out for its innovation, sustainability, and potential to revolutionise the future of lithium production. It represents a breakthrough in sustainable lithium extraction made in Europe, a critical element for the energy transition and the growing electric vehicle market in Europe and the world.
While Al-based adsorbents in single reactors are currently being used in the process schemes. a significant level of impurities are still contained within the resulting preliminary product. The technology, tested at the Bruchsal geothermal plant (Germany), offers a scalable and environmentally friendly solution for lithium production, strengthening Europe’s position in the global battery supply chain.
“It was a severe competition, and all the other nominated companies had excellent projects. We are very happy to have received this award,” said Thomas Koelbel, representing EnBW, while expressing gratitude for the recognition. Laura Herrmann, who was also representing EnBW, added that they “really want to continue with this project to bring it to the next level.”
President of EGEC, Miklos Antics praised the project, stating: “The CASCADE technology is a game-changer for the geothermal and battery industries. EnBW’s innovation demonstrates how geothermal resources can go beyond energy production to support critical raw material supply in a sustainable manner. This award highlights the role of geothermal energy in enabling Europe’s energy independence and climate goals.”
