In a step forward in decarbonising the constructure sector, HS2 has installed four 30-metre deep piles on a London site using a hydrogen dual-fuel piling rig. World first as HS2 trials dual-fuel piling rig on London site: World first as HS2 trials dual-fuel piling rig on London site

The trial took place as part of work done in partnership by ULEMCo and Cementation Skanska, working with the world-leading Business Research Establishment (BRE), funded through the BEIS Phase 1 Red Diesel Replacement competition.

ULEMCo and Cementation Skanska successfully modified a medium sized CFA piling rig, converting it so that the machine component operated using energy from on-board hydrogen tanks. Using the dual-fuel system, both diesel and biofuels (HVO) can be mixed with hydrogen, displacing the fuel with hydrogen, resulting in a reduction in fuel use and lower CO2 emissions.

The trial is one of several initiatives being undertaken by HS2 in its commitment to decarbonising construction sites and achieving completely diesel-free sites by 2029.


Andrea Davidson, Head of Environmental Sciences for HS2 Ltd, said:

“HS2 is continuing to drive a positive change in the construction sector and is providing an important environment to develop the real-world use of hydrogen energy technology. The development of dual-fuel systems that can be used to adapt existing equipment so it can run off cleaner, low carbon energy sources, could be a game changer across the construction sector.”

Terry Muckian, Managing Director, Cementation Skanska, said:

“Using this rig in a real-world environment to install piles on a commercial site is an exciting milestone. It follows the success of the simulated trials last year and is the next step towards rolling the technology out more widely."

Amanda Lyne, Managing Director, ULEMCo, said:

“The machines used in construction are owned and used for many years, so demonstrating a decarbonisation solution that utilises these existing assets is not only cost-effective but also important for sustainability.”
