The Advanced Propulsion Centre UK has introduced a new report focusing on the benefits and applicability of hydrogen internal combustion engines (ICE) in decarbonizing heavy-duty vehicles (HDVs) and off-highway machinery. Despite the ongoing energy transition, the exact role of hydrogen in decarbonization remains uncertain, although it's recognized as a viable solution for hard-to-decarbonize sectors. The report delves into the potential of both hydrogen ICE and fuel cells in the 'hydrogen landscape for automotive insight report.' Philippa Oldham, the Stakeholder Engagement Director at APC, emphasizes the UK's heritage in ICE design and manufacturing, suggesting that this expertise can be leveraged for hydrogen ICE. She highlights the advantages of hydrogen ICE in terms of fast refueling, range, performance, and retrofit solutions, catering to applications where battery electric vehicles face challenges. The report underlines the significance of hydrogen ICE in managing transitional costs while positioning the UK as a global leader in hydrogen ICE innovation and production, particularly for industrial transport. Dr. Hadi Moztarzadeh, the Head of Technology Trends at APC, stresses the importance of policy and regulation development to support hydrogen ICE adoption. The report demonstrates that hydrogen ICE, with suitable after-treatments, could drastically reduce CO2 emissions and global warming potential compared to current diesel engines. This aligns with the UK's goal to achieve a 90% reduction in carbon emissions by 2040 and a complete ban on internal combustion engines by 2035. The APC urges the automotive sector to engage in discussions regarding future pathways and innovation for hydrogen ICE and fuel cell technologies, aiming to accelerate the transition to zero-emission transport solutions. Overall, the report presents a positive outlook on the potential of hydrogen ICE as a promising solution for challenging sectors in achieving decarbonization goals.
