Canada's planned submarine fleet could eventually be connected to technology that converts discarded aluminum into hydrogen. GH Power, a Canadian company, is discussing with Germany's TKMS how its modular chemical reactor could fit into the industrial base being developed around Canada's future submarine fleet, as per a report.
The technology uses scrap or recycled metal, mostly aluminum, together with water to produce hydrogen, high-purity alumina and heat, as per an Autonocion report. The potential connection is relevant because the Type 212CD submarines selected by Canada use hydrogen fuel cells as part of their air-independent propulsion system.
