DB ESG, receiving funding from Innovate UK, is exploring the impact of hydrogen injection and carbon capture technology on rail vehicle emissions as part of the UK government's initiative. Collaborating with AHT, they aim to extend the lifespan of engines and reduce emissions. With significant diesel-powered rail operations in the UK, the project seeks to cut carbon emissions using innovative technology. AHT's hydrogen injection and carbon capture system, successful in road transport, will be tested for scalability in the rail sector. The trial will focus on enhancing combustion efficiency and reducing harmful exhaust emissions through hydrogen injection and carbon capture. If successful, this project could offer a practical and scalable solution for decarbonizing rail, providing an alternative to full electrification. Overall, the initiative presents a positive step towards sustainable rail operations and meeting environmental targets.
