GCK Mobility, a leading French company specializing in retrofitting heavy vehicles, has been selected by SUEZ, a global leader in circular solutions, for a significant project. The collaboration involves transforming two thermal household waste bins into vehicles powered by hydrogen fuel cells. This initiative is part of the collection services contract with the Grand Paris Sud Est Avenir Territory, aiming to convert 26-tonne Renault D-Wide waste collection vehicles into zero-emission ones. The vehicles will be equipped with a hydrogen fuel cell system developed by GCK Battery, providing a hydrogen storage capacity of 17 kg for efficient daily collection operations. This innovative solution offers the benefits of electric vehicles, such as zero emissions and reduced noise pollution, while leveraging the flexibility of hydrogen. The integration of hydrogen fuel cells ensures optimal autonomy, addressing the challenges of decarbonization. The project aligns with the Territorial Climate Air Energy Plan (PCAET) of the territory, focusing on energy transition and climate change mitigation. The partnership between GCK Mobility and SUEZ signifies a significant milestone in the decarbonization of urban heavy-duty vehicles. The electric-hydrogen retrofit solution not only accelerates fleet decarbonization but also preserves material capital for local authorities and major organizations like SUEZ. This demonstrates the effectiveness of technological innovation in supporting environmental public policies. GCK Mobility's expertise in retrofitting vehicles is evident from previous projects with other local authorities. The company's role as an enabler of innovative public policies in decarbonization is solidified through partnerships with various communities. The delivery of the transformed vehicles is scheduled for autumn 2025, following necessary approvals. This initiative showcases the potential of hydrogen-powered vehicles in enhancing sustainability and driving environmental initiatives in the transportation sector.
