Liebherr is urgent forward with its efforts to section out fossil fuels on its job websites, however they don’t suppose battery-electric is the very best answer for the heaviest heavy gear – and the corporate’s newest hydrogen-powered wheel loader looks like it’s struggling to show that time.
Regardless of the corporate’s efforts to convert among the largest development and mining machines on Earth to battery-electric energy (efforts which have seen greater than 1,000,000 tons of fabric muscled apart), the corporate says it’s struggling to make a 40+ ton electrical wheel loader make industrial sense.
At first blush, these look like contradictory statements – however grasp on. Mining gear like large excavators and 100+ ton haul vehicles spend a ton of time in a single place, and have a tendency to function in environments which have constant entry to grid energy. That’s why it is sensible for Liebherr to affect its 300 ton cellular container crane, however why it might not make sense to affect something a lot greater than their L 507 E compact loader.
Liebherr believes batteries don’t is sensible for gear like this 40 ton wheel loader that may very well be requested to function in areas the place electrical energy could be arduous to return by. And, whereas Volvo is engaged on methods to carry energy to the job web site and Moog is engaged on modular batteries to do the identical factor, Liebherr is pushing hydrogen combustion as an answer for job websites that require lots of of kW of labor to be accomplished on a single shift.
And, as an off-road answer, it’s price noting that MW-scale batteries can be so heavy, utilizing present expertise, that they’re simply as more likely to sink into the mud and earth as they’re to successfully transfer it.
Liebherr L 566 H wheel loader
Although Liebherr didn’t launch any specs on its L 566 H, the diesel-powered L 566 Liebherr wheel loader has an working weight vary of as much as 58,310 kilos, and is able to carrying buckets as much as 15.7 cubic yards (for context, a full-sized pickup mattress has a 2-3 yard capability and may haul about one yard of sand and gravel).
The L566 H is predicted to carry out at the very least in addition to its diesel-fueled counterpart, however with a fraction of the tailpipe emissions.
That mentioned, getting the hydrogen to the tractor stays as large an issue as getting electrical energy to it. “To make progress in hydrogen analysis, we have to have entry to hydrogen,” says Dr. Ing. Herbert Pfab, Chief Technical Officer of Liebherr Bischofshofen. “We constructed this filling station (on the Liebherr plant in Bischofshofen) to additional advance our objectives for decarbonizing development equipment.”
Electrek’s Take
Look, Liebherr can discuss up its new hydrogen gear all it wats, however the actuality of this cynical money seize could be seen within the first press photograph (at high). In case you can’t see it: it’s the MAN truck. Considered one of 200 examples of a hydrogen combustion semi constructed to show that the tech isn’t prepared.
MAN Truck’s notoriously hydrogen-skeptical CEO, Alexander Vlaskamp, advised reporters that it was, “inconceivable for hydrogen to successfully compete with battery electrical vehicles,” again in January. “In the present day you can not purchase hydrogen for lower than 13 or 14 euros … and it isn’t inexperienced.”
Frankly, not a lot has modified since then – and it’s arduous to take a look at these hydrogen initiatives as something, apart from a method to funnel some hydrogen incentive cash into the company coffers.
That’s my take. In case you can consider one other one, tell us about it within the feedback.
