On August 26, 2025, Rock Tech Lithium and ENERTRAG SE signed a memorandum of understanding at the German-Canadian Critical Minerals Round Table in Berlin, outlining a long-term partnership to supply renewable energy for Rock Tech’s planned lithium hydroxide converter in Guben, Germany. The ceremony was attended by Canada’s Prime Minister, the Canadian Ministers of Energy and Innovation, and Germany’s Federal Minister for Economic Affairs and Energy.
Under the agreement, ENERTRAG will develop new wind and photovoltaic installations in the neighboring Polish municipality of Gubin and deliver at least 70 GWh of renewable electricity per year under a future power purchase agreement. This volume is expected to cover a minimum of 50 percent of the converter’s projected electricity demand from 2030, reducing its indirect CO₂ emissions (Scope 2) by approximately 50 percent. The arrangement also provides Rock Tech with greater planning security for operating costs.
The energy and sustainability model established for the Guben converter is intended to serve as a blueprint for Rock Tech’s second converter in Red Rock, Ontario, Canada, supporting the creation of a resilient, low-carbon supply chain for critical minerals across Europe and North America. The project has been designated a strategic initiative under the European Commission’s Critical Raw Materials Act.
“With the planned direct supply of our converter with renewable energy, we are setting an important milestone for the sustainable and competitive production of lithium hydroxide in Europe. The partnership with ENERTRAG is an important example of how industry and energy producers can work together in a practical way to decarbonize the value chain. This not only creates planning security for our project but also contributes to achieving European climate targets,” says Mirco Wojnarowicz, Chief Executive Officer (CEO) of Rock Tech Lithium.
The collaboration remains subject to positive investment decisions by both parties and underscores the close Canada-Germany bilateral cooperation in advancing clean-energy infrastructure and critical minerals strategies.
