Toyota HIACE – Hydrogen Vehicle / Fuel Cell
Toyota, a global leader in sustainable mobility solutions, has introduced a groundbreaking prototype of its HiAce van featuring a hydrogen-fueled internal combustion engine. The company is set to initiate a customer pilot program in Australia later this month, marking a significant step in Toyota’s comprehensive approach to decarbonization.
The innovative powertrain technology incorporated in the HiAce prototype aims to deliver ultra-low CO2 tailpipe emissions, aligning with Toyota’s commitment to a multi-pathway strategy for reducing environmental impact. This strategy encompasses substantial investments in carbon-neutral fuels, as well as advancements in hybrid-electric, plug-in hybrid-electric, battery-electric, and fuel-cell electric vehicles.
The Hydrogen HiAce prototype will undergo real-world testing by Australian companies during the customer pilot program. This initiative allows these companies to assess the viability of fit-for-purpose commercial vehicles boasting ultra-low CO2 tailpipe emissions. Valuable feedback from participants will contribute to refining the technology and accelerating the path to full commercialization.
Matthew Callachor, President and CEO of Toyota Australia, expressed pride in being selected to operate this Australian-first pilot program. He highlighted the technology’s potential to produce commercial vehicles meeting practical requirements while making substantial reductions in CO2 emissions.
Toyota initiated the development of the hydrogen-fueled internal combustion engine technology in Japan in 2017. Following its debut in a Corolla Sport in 2021, which participated in the Super Taikyu series in Japan, the technology was further refined for compliance with emissions standards and adapted for use in the HiAce.
The choice of the HiAce for the pilot program is strategic, considering its packaging flexibility. The ability to install the hydrogen engine up front and the fuel tanks under the floor ensures minimal impact on internal space and payload. The HiAce, commonly used for short “back to base” commercial operations, is versatile and suitable for various applications.
The prototype Hydrogen HiAce utilizes a modified V6 turbo petrol engine from some overseas markets, driving the rear wheels through a ten-speed automatic transmission. Engine modifications enable it to run on compressed hydrogen gas, achieving Euro VI emission standards. The powertrain delivers a maximum power output of 120kW with a peak torque of 354Nm.
While the hydrogen powertrain results in nearly zero CO2 tailpipe emissions, the combustion process generates minor amounts of oxides of nitrogen (NOx). Compliance with Euro VI emission standards is ensured through the integration of a selective catalytic reduction system.
Toyota is committed to optimizing the powertrain further by enhancing hydrogen storage, improving combustion, and exploring the addition of hybrid technology. The pilot program aims to fast-track the development of this new powertrain, with participating companies utilizing the HiAce for commuter or delivery-type operations.
CPB Contractors, a prominent designer and builder of large-scale infrastructure, will be the first participant in the pilot program. The company plans to use the Commuter version of the Hydrogen HiAce to transport workers across a major infrastructure project in Melbourne. Discussions are ongoing with several other interested companies.
The Hydrogen HiAce pilot program builds on Toyota Australia’s significant contributions to the development of Australia’s hydrogen economy. Previous initiatives include a 2018 trial of the first-generation Mirai FCEV with Melbourne councils, the establishment of Victoria’s first hydrogen production, storage, and refueling facility in 2021, and collaborations with businesses for the deployment of second-generation Mirai sedans.
In a recent milestone, Toyota signed a Memorandum of Understanding with Hyundai Australia, Ampol, and Pacific Energy to collaborate on the development of hydrogen refueling infrastructure. Beyond transportation applications, Toyota is committed to assembling fuel-cell generators at its Altona facility for French energy supplier EODev, with distribution planned for Australia and New Zealand.
