The Volvo Group has produced seven demonstration trucks that the company says can all be driven without emitting any carbon dioxide. The trucks, displayed in Sweden, were equipped with 9-litre diesel engines modified to operate on seven different types of renewable liquid and gaseous fuels; biodiesel, biogas combined with biodiesel, ethanol/methanol, DME, synthetic diesel and hydrogen gas combined with biogas.
However, Volvo says that it recognizes that the supply of different renewable fuels is significantly limited and there is no large-scale production or distribution for the majority of the alternatives that could be utilised in CO2-free haulage.
