Vehicles running on cooking oil deliver big carbon savings

A study has shown that low-carbon trucks running on used cooking oil (UCO) can achieve 97% carbon savings in comparison with dual diesel/gas engines.

The two-year trial was commissioned by Convert2Green (C2G), an energy-from-waste group funded by the Government’s Office for Low Emission Vehicles and Innovate UK.

The ‘ultra biofuel’ is made by processing UCO and animal fats which can then be used in any diesel engine.

The trial and subsequent report also made a lifecycle assessment of the fuel, which assesses environmental effects associated with all the stages of a product’s life.

The reported efficiency ratings showed:

  • tank to wheel was 86%
  • well to wheel 84%
  • a substitution rate of 85%, with no efficiency loss

In all 12 low-carbon systems were tested, with all but the UCO-powered vehicles based on gas. The trial found that UCO was also 14% more carbon-efficient than biodiesel.

Richard O’Keefe, managing director of C2G, said: “The UK alone produces 250 million litres of UCO each year, let alone animal fats, so the potential to use this system to convert that waste into a fuel of this calibre is incredibly exciting.”
