Volvo LNG trucks match diesel performance

Volvo Trucks is introducing Euro VI-compliant heavy duty trucks running on liquefied natural gas (LNG) 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 to 100% lower compared with diesel, depending on choice of fuel. The new Volvo FH LNG and Volvo FM Liquefied Natural Gas (LNG) are available with 420 or 460 hp for heavy regional and long-haul operations.

Lars Mårtensson, Director Environment and Innovation at Volvo Trucks, says, “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.”

Joe Pretorius, Brand Manager Volvo Trucks South Africa, says, “While these trucks will not be available to the South African market in the foreseeable future, Volvo Trucks has reduced the emission of air pollutants from new Volvo Trucks currently on sale in our market considerably and decreased fuel consumption as well as the overall impact to climate. With the development of these products, Volvo Trucks reiterates its commitment to become the most preferred sustainable transport provider.”

Instead of an Otto cycle engine, which is the conventional solution for gas-powered vehicles, the Volvo FH and 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 2 300 Nm while the 420 hp version produces 2 100 Nm. This is the same as Volvo’s corresponding diesel engines. Fuel consumption is on par with Volvo’s diesel engines, but 15 to 25% lower than for conventional gas engines.

Fuel is natural gas in the form of LNG 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% and if natural gas is used, the reduction is 20%. This relates to emissions from the vehicle during usage, known as tank-to-wheel.

To maximise driving range, tanks are filled with LNG, which is stored at 4 to 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 1 000 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. To ignite the gas, a tiny quantity of diesel is added at the moment of injection. A 100% reduction of CO2 emissions requires that fossil diesel is replaced with HVO – hydrogenated vegetable oils – and combined with bio-LNG.

Volvo Trucks is working 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.

Mårtensson says, “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.”

Sales in Europe of the Volvo FM LNG and Volvo FH LNG will start during spring 2018.
