But one can bring hydrogen with an electric truck…

Retric 2y ago
Hydrogen work vehicles require hydrogen storage and delivery. PEV work vehicles can also use hydrogen powered generators on site but they can also use anything from an on-site solar to a standard grid connection. As long as 98% of our hydrogen is coming from fossil fuels it’s only a net negative here.

  Whatever, good luck hauling electricity on a truck. We’re talking in the context of „you’re building a new highway, good luck getting enough electricity to charge those machines in that place”. What, you gonna haul your solar farm as the construction moves on for dozens of miles?

    Is it time to bring up swappable batteries again? You could truck in a trailer just like diesel.
    - rad_gruchalski 2y ago
      do that

    Why exactly would you want to haul electricity using a truck a rather than wires exactly? PEV’s are often more convenient and cheaper to use on a work site than diesel and are actually being adopted for that reason, it’s hydrogen that’s lacking distribution infrastructure.

        Look at the caterpillar line of EV vehicles they are becoming quite popular. Ex: 798 AC a 372 metric ton payload truck https://www.cat.com/en_US/products/new/equipment/off-highway-trucks/mining-trucks/15970073.html https://www.cat.com/en_US/products/new/equipment/off-highway... At the other end mini EV excavators are also becoming quite popular ex: Volvo ECR25, Bobcat E19e, etc

        Are you seriously showing me a mining truck and some micro machines you can use to dig a trench in your garden as an example of EV machines being „adopted”? Do you even know what makes those mining trucks functional for this use case? The deeper the mine, the more effective they are!

        Yes, people buying EV work vehicles are examples of EV work vehicles being adopted, which is pushing manufacturers to make ever more diversified product lines. A work crew putting in a trench really benefits from the equipment being quit. What you think of as “digging in your garden” is just one of plentiful examples of home construction scale equipment. There’s a lot of equipment that fits such purposes like rollers for people’s driveways etc. Here’s a preproduction equivalent to the hydrogen prototype mentioned in the article: 320 Electric Medium Excavator Operating weight: 22–24 metric tons | 48,501–52,911 lb Bucket capacity: 1.3 m³ | 1.7 yd³ https://www.cat.com/en_US/by-industry/construction/electric-products.html https://www.cat.com/en_US/by-industry/construction/electric-...

        What’s „long single charge run” an equivalent of?
