Biodiesel blend of 5% was tested in 2007 with the assistance of LTA and the bus companies. The tests included fuel consumption and opacity testing. At the end of the testing period mixed results were obtained for the buses and vehicles. To improve its facility for fuel testing, the Department of Energy installed a B100 testing facility at the Central Plant pool Walubay in 2015. The facility is compatible with and can test B100 and E100 fuel blends.
Furthermore, the Department has also been working with USP to establish an accredited biofuel laboratory at USP. This is the first of its kind in Fiji and the region and the facility will be able to test biodiesel and ethanol fuels.
