A piling-rig that runs on a dual-fuel hydrogen and diesel system has been tested at a construction site in London, UK, for the HS2 high speed rail project.

As part of the trial, four 30-metre deep piles were installed using the rig, which the companies believe is the first time that hydrogen fuel has been used in a real world application on a construction site, with hopes that it could pave the way for the decarbonisation of the industry.
