CMB.TECH is a Belgian technology company focused on decarbonizing shipping and heavy-duty transport through hydrogen- and ammonia-based solutions. A subsidiary of Compagnie Maritime Belge (CMB), it develops and integrates dual-fuel and zero-emission propulsion systems, working with engine OEMs to adapt hydrogen and ammonia for marine and industrial use. The company designs and operates vessels and equipment powered by these fuels, including tugs, crew transfer vessels, auxiliary power units, trucks, and off-road machinery.
Beyond propulsion, CMB.TECH builds parts of the supporting value chain, such as on-site hydrogen production, refuelling and bunkering infrastructure, and fuel handling and safety systems for ammonia. It collaborates with shipowners, ports, and energy companies to accelerate practical deployment across commercial operations. Headquartered in Antwerp, CMB.TECH runs projects and partnerships in multiple regions, reflecting its role at the interface of maritime operations, energy technology, and emerging low-carbon fuels relevant to the chemical and logistics sectors.
