Scania and Holcim are Running Two Road Trains on Hydrogen Hybrid Fuel
BUILDING materials company Holcim has reduced fuel consumption by up to 15 per cent in two of its 100-tonne payload Scania trucks by retrofitting a hydrogen hybrid system.
The two prime movers each have a HYDI ‘Hydrogen on Demand’ HY2500 vertical unit that produces hydrogen on demand for controlled delivery to internal combustion engines.
Holcim said it has seen reductions in fuel consumption of up to 15 per cent.
But this is only part of the benefit of the hybrid system according to Adam Evans, the logistics manager at Holcim’s Aggregates Western Australia division.“On top of the fuel consumption figures, excitingly, we’re seeing the additional emission reductions of 17 per cent less carbon dioxide (CO2), 80 per cent lower diesel particulate matter (DPM), 22 per cent lower nitrogen oxides (NOX), and 25 per cent lower carbon monoxide (CO),” he said.
“Holcim has seen fuel performance savings estimated at 15 per cent when hauling payloads up to 100-tonnes in three-trailer combinations.”
Scania Australia general manager of Mining, Robert Taylor, said the Scania onboard management system confirmed the figures.
“The reductions in fuel burn and reductions in emissions, is entirely in line with our aim at Scania to reduce emissions during the entire working lives of our products,” he said.
Holcim, Scania and HYDI are partnering to decarbonise the logistics chain in Australia’s remote north-west.
The Pilbara is a vast region of endless red landscapes, twice the size of Great Britain, located in the north of Western Australia.
Holcim Australia uses road trains to transport quarry materials from the Turner River, Newman and Nickol Bay quarries in the Pilbara region to fixed and mobile concrete batch plants and other customers using Scania R620 V8 Euro-5 145-ton rated prime movers.
Each road train pulls a payload of up to 100 tons in triple (three-trailer) configurations, on haul distances from as little as 10km, up to 600km. Holcim is set to install HYDI systems in two additional prime movers as well as some of its contractor fleet throughout Western Australia.
“We are also exploring options to have HYDI units installed on other equipment including diesel generators and heavy mining equipment,” said Mr Evans.
The HYDI unit produces hydrogen from distilled water using electrolysis via a proton exchange membrane. The unit draws a low electrical input from the host engine while in operation.
Hydrogen supplements the diesel fuel to create a cleaner and more complete combustion process with the amount of hydrogen produced optimised for the capacity and application of the engine.
Developed in Australia over more than a decade, the leading-edge technology delivers improved machinery performance by increasing torque, a reduction in fuel consumption, cleaner burn that reduces engine soot and extends oil and filter service intervals, and lower harmful emissions – including DPM, CO2 and CO.
The system provides the capability to transition heavy, diesel-powered machinery into cleaner, more cost-efficient equipment at a fraction of the cost of replacement.
HYDI managing director John. Wilson said: “HYDI’s technology harnesses the benefits of hydrogen in an efficient, affordable and sophisticated way scaled to apply to multiple applications.”
Scania has been a committed and enthusiastic partner in the trial and are honouring the original repair and maintenance package provided with the vehicles.
Scania’s Adam Evans said: “Scania stepped up to the project, made sure we had all the vehicle and system information needed for a smooth installation of the HYDI units, and are eager to help us extend the project even further.”
The HYDI Hydrogen on Demand system can be simply, quickly and relatively inexpensively integrated into the existing diesel technology of Scania vehicles.
“In Australia we have to say that realistically the general availability of reliable, affordable hydrogen as a fuel for heavy haulage is still some way off, particularly regarding use in remote mining operations,” Mr Taylor said.
“As a result, the HYDI Hydrogen on Demand solution does appear to be providing a real-world and affordable solution for our customers who want or need to make an immediate reduction in fuel burn and their carbon footprint emissions across their transport functions.
“The investment and installation of this leading-edge transitional technology into our fleet further highlights Holcim’s commitment to reduce its Scope 3 emissions on our journey to reducing absolute Scope 3 Greenhouse Gas (GHG) emissions 90 per cent by 2050 from a 2020 base year.
