September 18, 2021. Scania adds the all-new 13-litre gas engine that can run on natural gas and on biogas – regardless if the gas is in compressed or liquefied form – as well as new tank options.
“Our 13-litre gas engine and new tank options facilitate travel operators to switch to biogas without issues with range and while still providing the power needed for any operation. Another upside is that it doesn’t take a huge investment,” says Jonas Strömberg, Sustainability Director, Scania Buses & Coaches.
Currently, biogas is used in compressed form mainly by city and suburban buses, cars and light transport vehicles, but has been less competitive for heavy long-distance vehicles. In recent years, technology that enables to cool the biogas, turning it into liquid and more energy-dense is available. This enables using the gas for heavy transport. The new engine and tank options make that a reality for Scania coaches. “Biogas will be one of the key tools for decarbonization of heavy duty transport – especially for intercity and long-distance operations. Half of Europe’s heavy duty gas fleet could be powered by biogas in 2025,” says Strömberg.
Running on both liquefied gas (LBG/LNG) and compressed gas (CBG/CNG), the benefits with the new engine are many: it can use fossil-free fuel, renewable, locally produced that reduces emissions. “Biogas is not only one of the fuels with the lowest CO2 emissions – it also solves local waste problems, creates local jobs and brings carbon and nutrients back to the soil. It is circular economy in practise,” Strömberg adds.
By switching to locally produced liquid biogas as fuel, operators can reduce both their own and their customers’ climate impact by up to 90%. Air quality in general is positively affected by reduced emissions, and the quieter vehicles benefit drivers, passengers and crew.
With the possibility to use liquified gas and with the new tank options, the range achieved will be enough for any travel operation. The powertrain combination also makes it possible to build coaches in the same way as has previously been done with diesel engines.
Moreover, the 13-litre engine offers the power and torque of equivalent diesel engines, meaning it can handle even the toughest challenges. This makes it the most sustainable, yet viable powertrain option on the market for long-distance operators.
Furthermore, Scania gas engines require no additives to use the fuel, eliminating dependence on the additive’s availability, all while reducing operating costs.
