Hydro Tasmania has been monitoring the development of biodiesel for sometime; it has the potential to be a substitute on King Island for ‘regular’ diesel – known as mineral diesel.
By implementing biodiesel, Green House Gas emissions can be substantially reduced. There are, however, differences in the properties between biodiesel and mineral diesel. This means that it isn’t as simple as just switching fuels. The best approach is to test the performance of biodiesel in controlled conditions prior to any potential implementation.
A number of trials were undertaken at the King Island Advanced Hybrid Power Station in order to prove operation of biodiesel in one of the existing diesel engines. Blending plant, filters and insulation was installed allowing the operation of biofuel in any blend from 5-100 per cent. The King Island Advanced Hybrid Power Station operated solely on B100 (100% biodiesel) on 22nd Feburary 2014, with B20 (20% biodiesel) being run station wide from April 2014.
This gave Hydro Tasmania the opportunity to test not only operational characteristics of the engines but also the fuel supply logistics, suitability of existing fuel infrastructure and trial the reliability of biodiesel suppliers. Blends of bio diesel and mineral diesel, as well as 100% bio diesel trials took placing using different types of bio diesel.
At the successful completion of the trial, the station diesel supply infrastructure such as tanks, blending pumps and fuel lines were modified to allow the use of biodiesel that can be blended on site.
