A medium-sized piling rig used for installing deep foundation piles. In this trial, the CFA rig was converted to operate on dual-fuel hydrogen technology.

A conversion system that allows construction equipment to operate using a combination of hydrogen, diesel, and biofuels (HVO). The hydrogen displaces traditional fuel, reducing overall fuel consumption and CO2 emissions.

HS2's broader initiative to decarbonize its construction operations, including the dual-fuel hydrogen piling rig trial and other measures to eliminate diesel from construction sites.

A trial of a dual-fuel hydrogen piling rig on the HS2 London construction site, where a continuous flight auger (CFA) piling rig was converted to operate using hydrogen tanks alongside diesel and biofuels (HVO). The trial successfully installed four 30-meter-deep piles.

A medium-sized continuous flight auger (CFA) piling rig that has been converted to operate using a dual-fuel system combining hydrogen, diesel, and biofuels (HVO). The conversion allows the rig's machine component to be powered by on-board hydrogen tanks, reducing fuel consumption and CO2 emissions.
