A leader in rolling stock engineering, DB ESG is collaborating with cleantech specialist Advanced Hydrogen Technologies (AHT) to test an innovative hydrogen injection and carbon capture system on a Class 66 locomotive. The primary objective is to assess whether this technology can deliver whole-life cost benefits for the rail sector while contributing to the UK's Net Zero targets.
With over 5,000 diesel locomotives still in operation across the UK, the rail industry is under mounting pressure to cut carbon emissions. This project explores how hydrogen-enhanced combustion and carbon capture technology can significantly reduce exhaust emissions without requiring immediate full electrification.
“We hope this investigation will bring both economic and environmental benefits,” said James Hornsby, Projects Director at DB ESG. “Decarbonizing the rail sector is essential for meeting carbon reduction targets, and this trial could provide a cost-effective solution for lowering rail emissions.”
AHT’s hydrogen injection and carbon capture system has already demonstrated success in road transport. Now, this project aims to evaluate its scalability for the rail industry.
“This system has been proven to reduce emissions and fuel costs in other sectors," said Ben Kattenhorn, CEO of AHT. "We’re eager to showcase its potential in rail applications as the industry moves towards Net Zero emissions.”
The trial will begin with controlled testing to measure fuel consumption and emissions output under various operating conditions. Key areas of assessment include:
If successful, this initiative could provide a scalable, cost-efficient alternative to full electrification or complete engine replacement, offering a practical pathway to rail decarbonization.
