Heavy commercial vehicles manufacturer Volvo Trucks Southern Africa maker begins LNG testing

Heavy commercial vehicles manufacturer Volvo Trucks Southern Africa has brought in two liquefied natural gas (LNG) trucks to be used for local testing. These gas-powered trucks have specifically been developed for heavy regional and long-haul operations.

“Many of our customers already work hard to reduce their environmental footprint. Therefore, we see a clear potential for LNG units as a vital part of the solution,” says Volvo Group Southern Africa VP Marcus Hörberg.

He adds that the company’s vision is that trucks from Volvo will eventually have zero emissions, although the way of achieving that is not by one single solution but rather through several solutions in parallel.

LNG has promising potential as a substitute for diesel in trucks, with a good supply globally, and increasing availability locally. When cooled down to low temperatures, the gas liquefies and reduces in volume, which means increased capacity to carry more fuel.

Additionally, through fuel-efficient drivelines and chassis configurations, Volvo Trucks’ LNG range makes significant fuel and carbon dioxide savings possible. LNG is obviously a fossil fuel, but it can produce 20% lower carbon dioxide emissions than diesel.

The new gas-powered Volvo FH LNG drives and performs just like the Volvo FH you know, says Volvo Trucks Southern Africa product manager Eric Parry.

“The powertrain in the new gas-powered trucks is based on our renowned diesel engine technology. Also, by using LNG rather than compressed natural gas (CNG), it is possible to carry larger quantities of fuel and thus ensure the necessary operating range for long-haul assignments.”

Further, Volvo’s new gas-powered trucks offer the same fuel efficiency as diesel- powered equivalents and can operate at the same speed. However, since LNG is often cheaper, this offers a good opportunity to reduce fuel costs, the company says.

With the 205 kg LNG tank, European operators are seeing usable range of up to 1 000 km, depending on the terrain and payload carried.

“The engine is the heart of any truck,” explains Parry, who adds that the gas-powered G13C engine’s efficiency is on par with diesel. Operators can expect the same service intervals, reliability and performance.

As such, just like Volvo’s other Euro 6 trucks, the Volvo FH LNG makes use of selective catalytic reduction technology with Adblue and a particulate filter for exhaust after-treatment.

When it comes to the provision of LNG to fleets, new local developments and partnerships in the segment have resulted in the establishment of a limited infrastructure, specifically on the N3 highway between Durban and Johannesburg.

Filling LNG involves a different procedure and some safety precautions owing to the low temperatures of the liquid fuel, but it is neither complicated nor time consuming in comparison to a commercial filling station.

Parry highlights that as the LNG coverage expands, the viability of running vehicles on this efficient fuel alternative will certainly increase.

“We will soon start with local testing to establish how viable this is for our market and customers. Although LNG certainly does hold potential we should also note that diesel power trucks will be with us for the foreseeable future.”

Moreover, Volvo Trucks will also assist with driver training to assist fleet owners.

“Reducing climate-impacting emissions from heavy commercial traffic is a challenge that engages politicians and transport purchasers, haulage companies and vehicle manufacturers. As Volvo Trucks, we are determined to play a leading role in bringing innovative and environmentally friendly transport solutions, that will be good for the industry and the planet,” Hörberg concludes.
