Piling contractor Cementation Skanska is switching all its plant fleet, including piling rigs, to hydrotreated vegetable oil (HVO) in the New Year.
The decision follows a successful trial using the green bio-fuel on a Liebherr LB36 piling rig with an 390kW engine, the largest engine to ever trial the use of HVO.
The trial, carried out in collaboration with HS2 and the Skanska Costain Strabag JV, collected data measurements with the engine running on diesel and then the engine running on HVO fuel alone.
The data, verified by Brighton University, revealed that CO was reduced by 57%, NOx was reduced by 38% and PM reduced by 36% during the normal operations.
Terry Muckian, Cementation Skanska Managing Director, said: “The use of HVO on a piling rig of this size had not been tried in the UK before due to concerns over potential damage to the engine.
“Following this successful trial, we can confidently take this next step forward and demonstrate our credentials in green leadership to significantly reduce emissions associated with our plant.
“This move comes after Skanska mandated the use of HVO fuel to power all site plant and equipment and to act on our pledge to become Net-Zero Carbon by 2045.”
Use of Green D+ will lead to significant carbon savings compared to red diesel. Supplied by Green Biofuels, it is certified under the International Sustainability and Carbon Certification Scheme and exclusively generated from waste or secondary renewable sources.
