In order to maximise the driving range, the tanks are filled with LNG, which is stored at 4-10 bar pressure at a temperature of -140 to -125°C. The biggest fuel tank variant contains enough LNG for a range of up to 1000km. Refuelling takes about the same time as filling up with diesel. When driving, the fuel is warmed up, pressurised and converted into a gas before it is injected into the engine. In order to ignite the gas, a tiny quantity of diesel is added at the moment of injection. A 100 per cent reduction of CO2 emissions requires that fossil diesel is replaced with HVO (Hydrogenated Vegetable Oils) and combined with bio-LNG.
Volvo Trucks is now working together with gas suppliers and customers to develop the expansion of LNG infrastructure in Europe. This development is also being supported politically in many countries and by the EU. A strategy for expanding LNG infrastructure is also included in the European Commission and member states' action packages for securing Europe's long-term energy supply.
"Natural gas offers clear climate upsides, it is competitively priced in many countries, and there are sufficient reserves to justify large-scale use. Our focus on LNG vehicles is creating new prerequisites for our customers to run fuel- and cost-efficient operations. At the same time, we're making it possible for heavy truck operations to considerably reduce their climate impact," says Lars Mårtensson.
Sales of Volvo FM LNG and Volvo FH LNG will start during the European spring of 2018.
