Big truck manufacturers are beginning to pivot towards hydrogen as a cleaner energy alternative in the freight industry, aiming to combat the sector's significant carbon emissions. While electric batteries have limitations for long-haul trucking, hydrogen fuel cells present a more feasible solution, albeit with challenges like high production costs for green hydrogen. The industry is focusing on developing hydrogen combustion engines as an interim solution, prioritizing speed and cost-effectiveness. The global efforts towards green hydrogen production using renewable sources like wind and solar power are gaining momentum, with projects underway in various regions. The potential of hydrogen lies in its ability to reduce carbon pollution, as burning hydrogen only emits water vapor, offering a promising pathway to a sustainable future.
