Wow!
picking a nit: the legislation is for low/no emission vehicles. It looks like hydrogen is a big part of that pie.
Calling Grant73 …… I thought that with electric motors that it's hard to generate the torque that you can with gas engines? And, with diesel you can generate more torque than with gas - that's why the big rigs are diesel? (please don't laugh at my ignorance). From what I saw in the article, there was no mention of all-electric big rigs - the big rigs mentioned are hydrogen powered.
Still, the article talks about electric medium duty pick-ups. Those would have to be huge electric motors, right?
This is super interesting …. the next step would be to try to push international shipping into lower emission power sources.
Where does hydrogen come from? If I had money to throw around, I'd be looking to invest some of it in hydrogen extraction companies (whatever that is). But, probably this development is already priced in. Hell, they'll probably drop on this news.
Right now, we're a one car, no car payment (yay!) family. It's been working great. And, we're hearing that school will be heavy on the distance learning, so mayyyyyyyybe we can hold out for a while. I feel like we're on the cusp of so many developments in transportation, it would be crazy to plunk down a bunch of cash for a car right now.
I'm sure I will lose this battle, but I really really want our next car to be an old autobody retrofitted with an electric motor.
Lastly, I must be misunderstanding this statement: "Nikola Motors hopes to gain traction thanks to the CARB ruling on zero-emissions trucks. The Phoenix-based start-up — which recently went public and now has a larger market capitalization than Ford"

The market cap is part of stock market silly season. Ford is a profitable company (normally) with vastly larger assets.

Back in my "play the market" days, I felt like the worst thing a company could do was become profitable. Once you are profitable, there are metrics and expectations. Before ….. it's all pie in the sky. |

OK, so here is the actual operative language. I think this actually helps manufacturers. It gives them a reason to keep developing their technology. Tesla and Nikola have been working on this for a few years already. Daimler and Volkswagen are also hard at work in this area. Ford just signed a joint development pact with Volkswagen, so they'll be in on this too. All you have to do is look out you window and see all the FedEx and UPS and other delivery trucks driving up and down your street every day to realize this is something that's really needed. Two things: - Electric motors generate more torque internal combustion engines. That's why Tesla's kill just about any other car off the line in a drag race.
- I don't see Hydrogen as a big player as an alternative fuel for quite some time. Certainly not for long haul trucking. There just isn't the infrastructure of Hydrogen fuel stations. I don't know for sure how easy it would be to build a bunch of them, but I don't think it would be as easy as building electric charging stations.

Ya, torque isn't the right word. What is the dynamic that causes big rigs to use diesel vs. gasoline? The article made no mention of electric big rigs. |

Diesel engines by design (longer stroke, more compression, inherent power in diesel fuel) produce more torque than gasoline engines; but generally much less horsepower.

Got to this thread late. As others responded, torque is better with electrics. Your locomotives are all electric, it is just simplest to diesel-POWER the generators which juice the on-axle electric motors. It's the electric motors that really propel the trains, and they would not "know or care" whether their power comes from batteries (which of course would be too heavy for the medium), from engines (those diesel generators) or pantographs (which is much more common for freight in Europe).
As to the big rig diesel versus gas, the longevity is why diesel won. Under the stress of heavy loads, a diesel can go 750,000 miles before a re-build, gas less than half that. And they do re-build, in the less legislative past, as many as two re-builds.
