Switch from HVO to LPG for Entire Site Compound

On this project there are two site compounds which were initially run using diesel generators. The diesel was switched to hydrotreated vegetable oil (HVO) as it was more sustainable and produced less emissions.

However, the cost of HVO has increased and the emissions are comparable to white diesel when comparing well to wheel. The diesel powered generators were not running efficiently as they were underloaded. HVO also has queries around the sustainability during production. The contractor were approached by a supplier who were offering an alternative way to power the site compound by using Liquid Petroleum Gas (LPG) tanks.

Since they can’t use the mains electricity to run the site offices and cabins, this is the best alternative for both health and safety and environmental factors. The predicted saving of this change is approximately £708,669.52 throughout the project.

By using LPG to power the site compound, emissions would be reduced compared to using HVO. The LPG tanks were resized to suit the compound and sited with suitably sized generators. This offers a reduced noise output and eliminate spillages and ground contamination whilst refueling the tanks.
