Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) signed a memorandum of understanding with ENERTRAG SE for renewable energy supply to its planned lithium hydroxide converter in Guben, Germany. The agreement was signed during the German-Canadian Critical Minerals Round Table in Berlin.



Under the partnership, ENERTRAG will provide at least 70 GWh of renewable electricity annually from new wind and photovoltaic plants, covering at least 50 percent of the converter's electricity demand starting in 2030. The renewable energy supply is expected to reduce the converter's indirect CO2 emissions by approximately 50 percent.



The electricity will come from new wind and solar installations in the neighboring Polish municipality of Gubin. Rock Tech states the arrangement will provide planning security for the converter's operating costs and serve as a blueprint for its planned converter in Red Rock, Ontario, Canada.



Canadian officials present at the signing included Prime Minister Mark Carney, Energy and Natural Resources Minister Tim Hodgson, and Innovation, Science and Industry Minister Mélanie Joly. Germany's Federal Minister for Economic Affairs and Energy Katharina Reiche also attended.



"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," said Mirco Wojnarowicz, Rock Tech's chief executive officer.



The Guben converter project has been recognized as a strategic initiative under the European Commission's Critical Raw Materials Act. Rock Tech's planned facility will have an annual capacity of 24,000 tonnes of lithium hydroxide monohydrate.



The cooperation remains subject to positive investment decisions by both companies, according to the press release statement.
