Hyundai’s hydrogen fuel-cell prototype is now market-ready and can be totally demonstrated at Bauma Munich, setting it as much as grow to be a standard-bearer for a development proper throughout the development automobile trade in direction of this zero-carbon gas
Hyundai Development Gear is to showcase its second-generation HW155H – a hydrogen gas cell-powered wheeled excavator prototype – at Bauma Munich. The primary model of the machine was displayed as a static exhibit at Bauma 2022, however it is going to now be totally operational within the demonstration space all through the occasion, exhibiting how hydrogen expertise can contribute to emission-free building operations.
The HW155H has developed since its preliminary presentation. “We aren’t speaking a couple of idea anymore, however we’re prepared for mass manufacturing,” explains Peter Sebold, product supervisor at Hyundai. “Nevertheless, we’re not launching the machine totally as a result of the market isn’t prepared for us or for hydrogen, when it comes to infrastructure and so forth.”
The automobile is powered by gas cells developed in partnership with Hyundai Motor Firm – a 30kW and a 50kW unit. The HW155H combines these to supply 70–100kW of energy, akin to a traditional diesel-powered excavator of this dimension. This energy is used to drive electrical motors or electrically-driven hydraulic pumps.
Stable-state of thoughts
Maybe essentially the most fascinating growth within the newest iteration is the hydrogen storage system. “The largest change is the tank system that now we have. It’s now a solid-state tank storage system, which is predicated on a expertise referred to as steel hydride,” says Sebold. “This expertise has by no means been utilized in building equipment, so it’s a first-time growth.”
The system works by having a strong construction as a substitute of getting a hole tank. “It’s a must to think about it like a sponge that’s absorbing the molecules of the hydrogen in fuel kind which allows extraordinarily excessive density,” says Sebold.
The solid-state storage resolution operates at a considerably decrease strain than typical techniques – round 300 bar in comparison with 750 bar – whereas reaching a larger storage density. “You truly compress the hydrogen, so that you improve the amount of the tank, which has as a optimistic consequence that the machine has extra fill, this implies it has longer autonomy,” says Sebold.
This improved storage capability permits for roughly 12 hours of runtime, with refueling taking simply 10 minutes. “There’s no charging, no batteries. You refill the machine in 10 minutes, like for those who had been filling up your automotive on the fuel station,” says Sebold.
Actually zero-emissions
Whereas hydrogen combustion engines are being developed by some OEMs and have clear benefits when it comes to counting on established ICE expertise and structure, fuel-cells have a bonus when it comes to emissions.
“Another firms are working and creating combustion engines,” says Sebold. “The distinction is, with a combustion engine, it’s not totally zero emission. You haven’t any extra CO2, – that’s eradicated – however you continue to have NOx, so there are nonetheless some emissions. The good factor about utilizing the gas cells is that it’s hydrolysis in reverse, mainly, and so the one emission that you’ve popping out is pure distilled water.”
Future pondering
The second-generation HW155H fuel-cell excavator has gained the eye of Bauma’s organisers, as confirmed by its nomination for Bauma 2025’s Innovation Awards within the Local weather Safety class. Because the honest in Munich will get underway Sebold anticipates vital curiosity from trade professionals: “It’s going to be fascinating and thrilling to see the reactions from the general public, prospects, contractors. I’m certain we are going to get requests to get the machine for testing functions in some job websites.”
As building firms face growing strain to scale back their environmental impression, hydrogen energy might signify a viable resolution for reaching sustainable operations whereas sustaining the efficiency ranges required in demanding building environments.
