Thyssenkrupp Marine Systems (TKMS) and Canada’s E3 Lithium have signed an agreement to explore integrating Canadian lithium into the supply chain for the Canadian Patrol Submarine Project (CPSP).
Beyond the submarine program, the collaboration will also assess leveraging Canada’s lithium production for potential international opportunities.
Lithium-ion batteries store significantly more energy than traditional lead-acid batteries, allowing submarines to remain submerged for longer periods.
Partnering with E3 would enable TKMS to source a critical component domestically, strengthening its bid for the more than $30-billion project.
TKMS is one of two finalists for the program, alongside South Korea’s Hanwha Ocean, to deliver 12 conventionally powered submarines for the Royal Canadian Navy.
“The CPSP represents a cornerstone of Canada’s naval capability, and critical minerals are essential to the technology that powers tomorrow’s submarines,” Chief Sales Officer at TKMS Thomas Keupp said.
“Through this agreement with E3 Lithium, we are not only securing access to a sustainable supply of lithium but also strengthening the industrial partnership between Germany and Canada. This cooperation reflects our shared commitment to innovation, sustainability, and long-term capability development.”
Leader in Canada’s Lithium Sector
E3 holds one of Canada’s largest lithium resource bases and, through its Clearwater Project, is expected to produce up to 36,000 tonnes of battery-grade lithium annually at full capacity.
Under the partnership, the company will provide expertise in lithium development, extraction, and processing to support the creation of a robust supply chain for the Canadian submarine program and potential international opportunities.
In addition to investment initiatives, the firms will collaborate on research and technology transfer.
“Partnering with TKMS allows us to connect Canada’s critical minerals industry with strategic global markets while supporting a transformative national defense program,” E3 Lithium CEO Chris Doornbos explained.
“This agreement is a strong step toward leveraging Canada’s lithium resources to create sustainable economic value, advance technology transfer, and strengthen industrial ties with Germany and allied nations.”
