Volvo introduces new LNG truck

New trucks from Volvo running on LNG offer the same performance as diesel, but with 20-100% lower CO₂ emissions

Volvo LNG TruckVolvo Trucks is now introducing Euro 6-compliant heavy duty trucks running on liquefied natural gas or biogas. The new trucks have the same performance, driveability and fuel consumption as Volvo’s diesel-powered models. Furthermore, the new trucks’ CO₂ emissions are 20–100 per cent lower compared with diesel, depending on choice of fuel. The new Volvo FH LNG and Volvo FM LNG are available with 420 or 460 hp for heavy regional and long-haul operations.

“With our new trucks running on liquefied natural gas or biogas, we can offer an alternative with low climate impact that also meets high demands on performance, fuel efficiency and operating range. This is a combination that our customers in regional and long haulage require,” says Lars Mårtensson, Director Environment and Innovation at Volvo Trucks.

Instead of an Otto cycle engine, which is the conventional solution for gas-powered vehicles, the Volvo FH LNG and Volvo FM LNG are powered by gas engines utilising Diesel cycle technology. This means that an operator who chooses gas can do so without compromising on driveability, fuel efficiency or reliability. Volvo’s 460 hp gas engine delivers maximum torque of 2300 Nm while the 420 hp version produces 2100 Nm. This is the same as Volvo’s corresponding diesel engines. What is more, fuel consumption is on a par with Volvo’s diesel engines, but 15 to 25 per cent lower than for conventional gas engines.

The fuel used is natural gas in the form of LNG (Liquefied Natural Gas) or biogas, known as bio-LNG. Both fuels consist of methane. If biogas is used, the climate footprint can shrink by as much as 100 per cent and if natural gas is used, the reduction is 20 per cent. This relates to emissions from the vehicle during usage, known as tank-to-wheel.

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 1000 km. 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_LNG_TruckVolvo 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 spring 2018.
