Several pilot projects involving hydrogen fuel cells in port operations are currently underway in Japan and Canada, aiming to advance decarbonisation efforts and reduce CO2 emissions. In Japan, initiatives such as the Mitsui PACECO H2-ZE hydrogen fuel cell RTG at the Port of Los Angeles and the hydrogen-fuelled RTG crane at Tokyo's Oi Container Terminal signify a shift towards sustainable practices. The conversion of cargo handling equipment to hydrogen in the Port of Tokyo reflects a broader decarbonisation strategy in the region. In Vancouver, Canada, DP World has successfully completed initial testing of a hydrogen fuel cell-powered RTG crane at the Port of Vancouver as part of the BCH2 Ports Project. The project involves retrofitting diesel-powered RTG cranes with integrated hydrogen-electric solutions to monitor performance indicators like hydrogen consumption and energy generation rates. DP World plans to convert its diesel RTG cranes to hydrogen-electric power, aligning with its zero-emission objectives. Hydrogen fuel cell technology is emerging as a promising solution for reducing carbon footprint in port operations. Concerns such as operational duty cycles for RTGs and technology reliability are being addressed through field trials and data collection. The successful deployment of hydrogen fuel cells in terminal tractors at the Port of Los Angeles demonstrates the feasibility of this clean energy source. Despite being an emerging technology, hydrogen fuel cells show great potential in revolutionizing the sustainability of port operations.
