Horizon fuel cells power Rockcheck’s trucks

The new Rockcheck heavy truck platform is designed around the core principles of ‘high efficiency, economy, and reliability,’ featuring multiple innovations within the fuel cell stack and system, Type IV hydrogen storage tanks, electric drive axles, and optimised overall vehicle weight. The hydrogen propulsion system was co-developed by Horizon and Rockcheck. It relies on Horizon heavy duty fuel cells containing patented graphite-metal, hybrid bipolar and proprietary hydrogen circulation module, boasting electrical efficiency of 49 - 60%. Combined with a dual-motor rear axle direct drive achieving over 93% transmission efficiency and an intelligent telematics management system, it forms a high-power, energy-efficient powertrain core.

The vehicle also benefits from advanced cooling and waste heat recovery capabilities, achieving substantial energy savings and overcoming the technical challenge of rapid cold starts at temperatures as low as -35°C. A lightweight design features in the 35MPa-450L Type IV hydrogen storage system produced by Tianhai Hydrogen Energy. This system reduces weight by 500 kg compared to traditional systems. Paired with a 750 MPa high-strength steel frame, the overall vehicle weight is limited to less than 10 t, significantly improving payload utilisation efficiency.

Particularly noteworthy is the vehicle’s hydrogen consumption, potentially as low as 7 kg per 100km when fully loaded, delivering significant economic advantages in long-haul logistics operations. The recently developed fuel cell system from Horizon is not only suitable for on-highway heavy-duty trucks, but can decarbonise diverse applications, such as large mining trucks and locomotives, and a wide range of diesel-burning equipment. It will further accelerate the transition to hydrogen in achieving vital emission reductions.
