TransNamib’s board has approved a six-month trial of a dual-fuel locomotive powered by hydrogen and diesel, as the rail operator tests lower-emission alternatives to its diesel fleet.
The pilot, to be conducted in partnership with CMB.TECH, will run for around 50 return trips along the Walvis Bay–Windhoek corridor, a key route for Namibia’s freight movement.
Chief Executive Officer Desmond van Jaarsveld said the trial will determine whether hydrogen technology can operate effectively under local conditions.
The locomotive will be assessed on fuel consumption, reliability, operational efficiency, maintenance requirements and overall cost-effectiveness, with a decision on potential expansion to follow after the trial period.
During the test phase, TransNamib will also evaluate safety procedures, staff training and operational readiness related to hydrogen storage, handling and refuelling. CMB.TECH will manage the hydrogen infrastructure and technical systems, while TransNamib focuses on operations and regulatory compliance.
The company’s fleet remains largely diesel-based, but a successful trial could pave the way for a gradual shift to dual-fuel technology.
Van Jaarsveld said the long-term viability of hydrogen-powered rail will depend on fuel costs, availability and performance in Namibia’s operating environment.
The trial forms part of TransNamib’s broader efforts to modernise its fleet and improve efficiency, while aligning with Namibia’s ambitions to develop a green hydrogen economy.
As the national rail operator, TransNamib plays a central role in freight logistics, with the Walvis Bay–Windhoek corridor serving as a vital trade route.
