The road to decarbonisation for the commercial vehicle sector is proving to be a complex and challenging journey, with experts highlighting that a straightforward ‘combustion engine ban’ for lorries and other commercial vehicles is far more difficult to implement than for passenger cars.

Following the European Union’s strict CO2 fleet regulations for passenger vehicles, which effectively introduce a ban on combustion engines, stringent greenhouse gas limits are also being rolled out for commercial vehicles.

Experts at the International Vienna Motor Symposium stressed that the industry is racing to develop a wide array of solutions to match the huge diversity of vehicles on the road – from long-distance trucks and small delivery vans to construction and agricultural machinery.

Prof. Bernhard Geringer, Chairman of the International Vienna Motor Symposium, noted that the entire commercial vehicle industry is working on a wide range of solutions needed to match the diversity of vehicle types on the road in view of the developments expected in 2026.

The legislative pressure is intense. Tobias Stoll, a project manager at the Research Institute for Automotive Engineering and Vehicle Engines Stuttgart (FKFS), pointed out that EU legislation stipulates ‘a 45 percent reduction in CO2 emissions by 2030 compared to 2019,’ with manufacturers facing heavy financial penalties for non-compliance.

This has set the industry's course, with Frederik Zohm (pictured above), Chief Technology Officer at MAN Trucks & Bus, expecting ‘major transformations in the commercial vehicle sector by 2030.’

Egon Christ, Chief Strategist at transport and logistics service provider Mosolf, commented: ‘The course has been set.’

However, the existing transport model, especially for long-haul journeys, is heavily reliant on fossil fuels. A typical diesel lorry has a service life of 1.5 million kilometres, often covering up to 200,000 kilometres annually.

Ten years ago, EU forecasts anticipated a dominant role for hydrogen and a minor one for battery-electric trucks. The reality has turned out to be ‘exactly the opposite,’ according to Nils-Erik Meyer, a division manager at Akkodis Germany.

Today, there are only around 10 fuel-cell truck models in the EU, compared to over 40 battery-electric models.

While battery-electric vehicles are currently the most technologically advanced, their widespread use hinges on a massive overhaul of charging infrastructure.

Oliver Hrazdera, site manager at Akkodis Austria, calculated: “For trucks with an electric range of 500 kilometres, the EU needs 2,000 charging points with 650 or 1,000 kilowatts of charging power.”

Batteries, payload and hydrogen’s setbacks

Freight companies prioritise fast turnarounds, which necessitates rapid charging. Dorothea Liebig, a manager at Shell Global Solutions Germany, explained that the maximum charging capacity for trucks ‘is up to eight times higher than for cars.’ She also highlighted the alternative of battery swapping, particularly prevalent in China, where it is ‘fully automated and takes just seven minutes’ at the over 1,200 existing battery replacement stations for trucks.

For many journeys, electric trucks are already viable. Meyer from Akkodis calculated that with a mandatory driver break and recharging, a truck could cover ‘around 630 kilometres are possible in one shift. This covers 90 percent of all journeys.’

However, a key disadvantage of battery-electric lorries is the impact on payload, which is reduced by ‘three to six tonnes for the drive system, mainly due to the batteries,’ according to Meyer. By contrast, hydrogen fuel cells only reduce the payload by one tonne.

Despite this advantage, enthusiasm for fuel cells has cooled in Europe. Markus Heyn, Managing Director of Robert Bosch and Chairman of Bosch Mobility, reported that in Europe and the US, a major hurdle has been the substantial cooling requirements for fuel cells, which need ‘two to two and a half times more cooling surface area than diesel trucks,’.

According to Rolf Dobereiner, product line manager at AVL List. This increased requirement consumes up to 40 kilowatts, reducing driving performance and creating challenges for achieving the high-power outputs needed for heavy-duty haulage.

An unexpected dark horse has emerged: the hydrogen combustion engine. This technology offers compelling benefits, as it doesn't require the costly, high-purity hydrogen needed for fuel cells.

Christian Barba, Senior Manager at Daimler Truck, noted that it saves costs ‘as 80 percent of the parts of a diesel engine can be reused.’

Moreover, Anton Arnberger, Senior Product Manager at AVL List, reported that it ‘is the only zero-emission technology that does not require the use of rare earths.’

The hydrogen engine ‘could achieve the torque and power of a gas or diesel engine,’ said Lei Liu, a manager at Cummins in Beijing. Cummins is testing these vehicles in India, where they are seen as a main pillar for transport decarbonisation, given the lack of a comprehensive power grid required for electric trucks.

Developers are also looking at alternatives to gaseous hydrogen. The trend in Europe is moving towards liquid hydrogen, which allows for longer ranges and is cheaper to store.

Furthermore, Yuan Shen, Chief Developer at Zhejiang Geely Holding in China, proposed methanol as ‘the best carrier of hydrogen,’ as it is a liquid fuel that is easy and safer to store and transport.

Shipping, special vehicles and hybridisation

Decarbonisation is equally challenging on the high seas. Andreas Wimmer, a professor at Graz University of Technology, reported that engines for the 100,000 ocean-going vessels in service today have a life span of over 25 years and cost hundreds of millions of euros.

By 2050, these giants must also be CO2-free. While the combustion engine will remain, fossil heavy fuel oil must be replaced by ammonia (considered an ‘up-and-comer’), methanol or limited-quantity biofuel.

The special vehicle sector – such as construction and agricultural machinery – presents one of the toughest challenges. Stefan Loser, department head at MAN Truck & Bus, noted that a forage harvester would need ‘36 tonnes of batteries to run purely on electricity,’ which is impractical. For such machines, which are used intensively for short periods, hydrogen fuel cells or combustion engines running on synthetic fuels will be essential.

Finally, in the USA, where the decarbonisation of transport is ‘less aggressive than in Europe,’ according to Chris Bitsis, head of development at the Southwest Research Institute, hybridisation (the combination of combustion engines and electric drives) is seen as a key strategy to maintain everyday usability while significantly reducing consumption and emissions.

Summing up the current situation, Prof. Bernhard Geringer concluded that battery-electric drives in commercial vehicles are currently only realistic for distances of up to 500 km and with sufficient fast-charging options. He stressed that the special vehicle sector is particularly difficult, which is where ‘hydrogen fuel cell drives or combustion engines with synthetic fuels come into play.’

Honda R&D, a subsidiary of Honda Motor Co., has developed underlying technology for a magnetic coupling wireless power transfer road system in partnership with Taisei Corporation and Taisei Rotec Corporation.

The system enables wireless in-motion charging for electric vehicles, including passenger cars and heavy commercial fleets. The partners plan to initiate demonstration testing on public roads starting in FY2027.

The technology integrates high-power-density receiver and transmitter units from Honda with a high-response direct current power supply system from Taisei and road-embedding construction techniques from Taisei Rotec. By supplying power to electric vehicles while in motion, dynamic wireless power transfer reduces the need for stationary charging infrastructure. The initial commercial focus targets logistics and transport operations, where continuous operation offers economic benefits.

The ground assembly embedded in the roadway combines the inverter and coil into a single unit designed to connect via direct current distribution. This design reduces component counts, simplifies wiring and supports installation into existing road surfaces through standard milling methods. The road pavement structures are engineered to withstand continuous traffic loads from vehicles weighing up to 20 tonnes (20,000kg).

Testing conducted at Taisei Group’s T-FIELD facility in Satte verified system stability and structural durability. Starting in late 2026, the companies will build a test roadway at T-FIELD Tamura to evaluate long-term durability under one million wheel-load cycles, measure power transfer efficiency at outputs up to 150 kW and analyse electromagnetic shielding.

The partnership will also join the Tateyama Expressway demonstration project managed by East Nippon Expressway Company starting in 2027.

Czech automaker Skoda Auto has expanded its powertrain portfolio with the introduction of a full hybrid powertrain for the Octavia, marking the first time the marque has offered this technology. The new powertrain is available for both hatchback and estate body styles in the Selection and Sportline trim levels.

The new Octavia utilises a series-parallel hybrid setup that combines a 1.5 TSI evo2 petrol engine with two electric motors, a single-speed automatic transmission and an automatic clutch that connects the engine directly to the front axle.

The smaller electric motor functions as a generator and starter, whilst the larger motor drives the front wheels and recovers energy during deceleration. The system automatically selects between all-electric, series hybrid, and parallel hybrid operation depending on speed, driver demand and battery charge levels. Electric mode offers a driving range of approximately two kilometres.

The model is offered in two power outputs: a 100 kW variant using a 96 kW petrol engine and a 125 kW version paired with a 110 kW engine. Both variants share identical electric motors and have an electronically limited top speed of 180 kmph. Energy is stored in a 1.6 kWh battery positioned beneath the rear seats, paired with a 40-litre fuel tank. Boot capacity is rated at 460 litres for the hatchback and 485 litres for the estate. Standard features include a 13-inch infotainment display and a 10-inch digital instrument panel. Orders open in October, with customer deliveries scheduled to begin in December 2026.

Johannes Neft, Chief Development Officer, Skoda Auto, said, "The Octavia is the first Skoda model to feature a full hybrid powertrain. Its series-parallel hybrid system combines a combustion engine with the flexibility of electric driving. Operating fully automatically, the system selects the most efficient drive mode according to the current conditions. The traction battery is recharged while driving by the combustion engine or through energy recuperation. With two output levels available for both the hatchback and estate, the full hybrid adds another technically versatile option to our powertrain portfolio giving customers even greater choice to match their individual needs."
