Today the transport sector is largely powered by fossil fuels. A combination of engine and driveline development as well as transport system efficiency measures and renewable fuels can provide modern energy for all.
In the summer of 2018, the English city of Nottingham received their 53rd double-decker gas-powered Scania buss, becoming the largest such fleet in the world. The city aims to have 120 of these buses in service by 2020, as the local authority takes bold steps to tackle the twin challenges of congestion and pollution that affect the 1.5 million inhabitants in the wider urban area. With the 53 busses 3,500 tonnes less CO2 is emitted and 0.75 tonne less particulates is emitted each year. Nottingham City Transport, the local-authority-owned bus company, has been pioneering the use of alternative fuels in urban bus operations, the latest incarnation of which is dedicated gas power. With plans for further orders of biogas double deck buses and to convert 185 existing buses to the latest Euro 6 emission standards, Nottingham City Transport is on track to reduce emissions by 90 percent by 2020.
Scania Transport Laboratory, a Scania subsidiary that handles 10 percent of the company’s inbound transport, was established with the aim of gaining knowledge for Scania. Through measures including driver training, and a focus on fill rates and efficient vehicles, the laboratory was able to reduce its carbon dioxide emissions by 50 percent between 2008 and 2014, calculated per tonne of goods transported. The increased efficiency is a result of improved driver behaviour, smarter maintenance, and the use of alternative fuels as well as relatively simple aerodynamic adjustments. Since then the laboratory has kept on working with continuous improvements by routing, filling rate and driver training, and during 2018 the fossil content was phased out and substituted by HVO, GAS, ethanol and hybrids which means that the transport lab now is running 100% fossil free.
Furthermore, vehicle electrification is rapidly advancing and offers a favourable path towards more sustainable transport solutions. For heavy trucks and buses, the continued development of both charging infrastructure and battery cell technology is crucial for a widespread market breakthrough in commercially viable electrification. Scania and Northvolt will partner up to develop and commercialise battery cell technology for heavy commercial vehicles. Production of battery cells is energy intensive and Sweden offers a solid supply of cost-effective green energy. The country is therefore well suited for large-scale sustainable battery production.
