The limited sales penetration of zero-emission trucks in Western markets reflects a lack of available zero-emission trucks rather than a lack of demand, according to IDTechEx’s new report, “Electric and Fuel Cell Trucks 2023-2043.”

Major corporations are clamoring for low-emission trucks (and greater support from governments) to help them meet their corporate pledges to reduce their greenhouse gas emissions in line with the UNFCC Paris Agreement and national net zero-emission targets. In recognition of this demand, most major OEMs have launched or are about to launch a zero-emission truck into series production.

With vehicles now becoming available and production scaling up, IDTechEx expects the global market to grow rapidly at a CAGR of 37.1% over the next decade. Despite increasing interest in zero-emission trucks, and substantial recent progress, the global market share of zero-emission trucks in 2021 was only 0.4% of total sales, approximately 13,000 units, with the vast majority in China, says IDTechEx.

Whilst long-haul applications are not yet feasible, a large percentage of urban and regional routes are deliverable with battery electric trucks. Longer range duty cycles will become possible in the future with improving battery pack energy density, better brake energy recuperation, and charging strategy optimization during breaks in operation.

For BEV trucks to deliver longer-range applications, they will need a large battery capacity, but as such, will require considerable time to charge once depleted, this could hinder the flexibility vital to some freight operations, the report states. Fuel cell systems, which generate electricity from pressurized hydrogen stored on-board the truck, offer the possibility of zero-emission long-haul transportation without the need for unfeasibly large batteries and with the ability to refuel in a similar time window to diesel.

The lack of hydrogen refueling infrastructure is a hindrance to FCEV rollout, however, several countries including Japan, Korea, Germany, and China are supporting initiatives to build hydrogen refueling stations, which could see FCEV become increasingly operable, the company says. A major challenge will also be producing low-carbon hydrogen at a cost that enables it to be a commercially viable ‘green’ automotive fuel. Today hydrogen is primarily produced from natural gas and has a large carbon footprint.
