Several original equipment manufacturers (OEMs) are shifting their focus towards hydrogen-fuelled combustion engines for mid-size and heavy equipment, considering them as a promising alternative for machines with higher power demands. While battery technology has made strides as an alternative power source for compact vehicles, the industry is showing a strong inclination towards hydrogen-fuelled adaptations for heavier machinery. Despite the showcasing of prototypes at trade exhibitions, full market availability and widespread adoption of this technology still seem distant. JCB, a prominent player in this transition, has transitioned from hydrogen fuel cell technology to hydrogen-fuelled internal combustion engines. The company has developed a specific oil and additive pack and high-efficiency turbocharger to enhance hydrogen combustion efficiency. JCB has also introduced a mobile hydrogen refueller designed to transfer fuel between storage and hydrogen-powered machines efficiently. Similarly, Manitou Group is actively involved in developing hydrogen-powered prototypes, aiming for 43% of its product line to be low-emission by 2030, showcasing a strong commitment to integrating hydrogen technology. Liebherr is also making strides in this field, working on hydrogen engines expected to enter series production by 2025. The industry's shift towards hydrogen technology signals a significant push towards sustainability and innovation. With companies investing in both vehicle development and infrastructure, the future of hydrogen-fuelled farm and construction equipment appears promising.
