Electricity is continuing to gain traction in previously thought to be hard-to-electrify sectors including heavy trucking and aviation. Electricity’s share in transport will grow from 1% today to 23% in 2050, according to DNV’s latest Transport in Transition report.
DNV’s Transport in Transition report is a deep dive into the energy transition of transport – the most dynamic of the energy demand sectors through to 2050. The report draws on DNV’s system dynamics-based Energy Transition Outlook model and explores the vast changes in fuels, electricity and infrastructure needed to transport ever-larger numbers of people and volumes of freight while at the same time decarbonizing the sector.
Road transport leads the way in reducing reliance of fossil fuels, falling from 38 million barrels per day (bpd) today, to 19 million bpd in 2050, reducing share from 91% to 57%. Conversely, the consumption of oil within aviation will be virtually flat to 2050, with hydrocarbons set to have a 60% share in the sector in the same year.
Driven by the decarbonization push, the fuel mix in the maritime sector will also change significantly over the coming decades. By 2050, it will likely transition from being almost entirely oil-based to an energy mix comprising of 50% low- and zero-carbon fuels, 19% natural gas and 18% biomass. Electricity will obtain only a 4% share, from short sea shipping and port stays for larger vessels.
Regions such as Europe, North America and Greater China are frontrunners in the uptake of battery electric vehicles (BEVs). In parallel, those regions are investing in hydrogen and hydrogen-based fuels as the most promising option for moving heavy goods over long distances. At the other end of the spectrum, regions including Sub Saharan Africa and North East Eurasia remain far away from establishing the infrastructure and producing the quantities of renewable electricity required to decarbonize road transport.
Remi Eriksen, Group President and CEO at DNV said: “Our Transport in Transition report highlights the challenges facing the industry and where further policies and investments are urgently needed to fast-track decarbonization of the transport sector. There is a pressing need for reliable non-fossil fuels to support emission reductions, particularly in the maritime and aviation sectors. It is essential that policy makers accelerate efforts to incentivize research and development, pilot projects and commercial uptake of carbon-neutral and zero-carbon fuels across the transport sector to support mid-century net zero goals.”
The report also underlines the clear challenge in deriving a single solution for the decarbonization of transport with a number of constraints associated to the adoption of biofuels, renewable electricity and CO2. There is no ‘one size fits all’ with a variety of energy sources needed to tackle the challenge in each sector, such as BEVs for passenger vehicles and trucks, fuel cell electric vehicles for the heaviest long-distance trucks, and bio- or hydrogen-based synthetic low or zero-carbon fuels for maritime and aviation.
Encouragingly, as the aviation sector strives to support decarbonization efforts, the results highlight that biofuels are set to supply a quarter of aviation demand by 2050. However, the report emphasises the importance of governmental and industry back-up to manage the rise in advanced biofuels for aviation and maritime, with the sustainable fuel expected to be more expensive than fossil fuel counterparts. On the other hand, for sectors that can use direct electrification, future users will gain from superb efficiency in electric drivetrains and experience cheaper transport.
