Hydrogen Combustion Engines: A Quick Fix for Truckmakers
Key Ideas
  • Truck manufacturers like Volvo and MAN are exploring hydrogen combustion engines as a quicker, low-cost solution to achieve zero emissions in the industry.
  • Despite challenges like harmful emissions and fueling infrastructure, companies are adapting existing manufacturing lines to accommodate hydrogen combustion engines.
  • The transition to hydrogen combustion engines provides a bridge to green hydrogen technology and allows for a gradual reduction in carbon emissions in the trucking industry.
  • Major players in the industry, including Bosch and Cummins, are optimistic about the role of hydrogen combustion engines in the energy transition for heavy-duty vehicles.
The global truck making industry is facing the challenge of transitioning to zero emissions, with electric batteries being unsuitable for long-haul freight operations due to weight and charging constraints. To address this, truck manufacturers like Volvo and MAN are turning to hydrogen combustion engines as a more feasible and economical alternative. Although hydrogen fuel cells are also being developed, the immediate focus is on adapting existing combustion engines to run on low-emission hydrogen. Despite concerns over harmful emissions and the need for larger pressurized tanks, companies are investing in developing this technology. The scarcity of green hydrogen remains a significant hurdle, but initiatives from the EU and the US, along with industry partnerships, aim to address this challenge. While the rollout of green hydrogen infrastructure may take time, truckmakers are making strategic moves to bridge the gap by offering combustion engine models that can run on natural gas or biogas as an interim solution. This transition strategy allows for a gradual reduction in carbon emissions and provides a familiar technology for fleet customers. Overall, the sentiment towards hydrogen combustion engines in the trucking industry is positive, with stakeholders seeing it as a key step towards achieving sustainability goals.
