Insight 23: Electrifying Freight: Battery-Powered Heavy Goods Vehicles
Summary
Battery-powered and hydrogen fuel cell technologies are driving the energy transition in the UK’s heavy goods vehicle market. By 2050, electric HGVs are expected to dominate road freight, with hydrogen playing niche roles in long-haul and heavy-duty segments. UK research in high-energy-density batteries, particularly solid-state and lithium-sulfur, will be crucial for global leadership in the electrification of freight.
Focus of the Insight
The Insight:
- Explores the role of the HGV sector as a significant part of the UK’s economy and the challenges of decarbonising the sector.
- Assesses the size of the battery-powered HGV market at the UK and Global level.
- Outlines the performance characteristics of battery technology for different applications across the HGV sector.
- Analyses UK depot-based charging and public charging infrastructure.
- Proposes actions to develop and support the UK HGV industry.
Conclusion
The transition to low- or zero-carbon HGVs is advancing rapidly, albeit from a low current uptake, with battery electric and hydrogen fuel cell drivetrains emerging as the most viable options for mass market adoption. HGVs will be subject to a UK government mandate to phase out the sale of petrol and diesel HGVs by 2040, with different timelines by vehicle class. Along with the requirements imposed by regulations, consumers and freight operators will also influence the choice of technologies.
The adoption of BEVs is driven by cost reductions and efficiency improvements. The sharp decline in battery costs has already positioned BEVs as the most cost-effective alternative option to diesel in many applications when considering the total cost of ownership, particularly in urban and short-haul duty cycles. By 2040, BEVs are expected to comprise 45% of the UK commercial vehicle stock, increasing to 80% of the stock by 2050. Hydrogen FCEVs, however, are likely to remain a niche solution, particularly suited to high-payload and long-range applications.
To support the transition to battery electric HGVs and address the operational demands of the freight industry, the following strategic actions are recommended:
- Invest in next-generation technologies, such as solid-state batteries and silicon anodes, to accelerate advancements in battery energy density and reduce ultra-fast charging times, supporting long-haul applications and heavy payloads.
- Promote the UK production of HGV-specific battery systems, particularly high-capacity packs for long-haul vehicles and advancements in thermal management, cycle life and weight optimisation.
- Upgrade and expand the HGV-specific UK charging infrastructure, particularly strategically located public ultra-fast charging points on the SRN as well as depot-based solutions.
- Invest in grid capacity upgrades and power supply resilience to ensure the charging network meets the energy demands of an increased electric HGV fleet, with investment focused on high-demand freight corridors and urban logistical hubs.
- Integrate renewable energy sources, such as solar and wind, into charging infrastructure to reduce reliance on conventional power grids, and lower energy costs.
- Strengthen collaboration among energy providers, policymakers and industry stakeholders (Road Haulage Association, Logistics UK etc.) to address technical and logistical challenges, particularly in coordinating depot and public charging networks.
Achieving a zero-emission heavy-duty vehicle fleet by 2050 is feasible but will necessitate extensive planning, coordination and investment in infrastructure, alongside robust government policy support. With targeted efforts across industry and government, the transition to zero-emission HGVs has the potential to reduce dependency on imported fuels, create new jobs and position the UK as a leader in the electrification of freight.
