Even if ignited, it is far less dangerous than gasoline, diesel, propane, or a battery. It would burn off in seconds and be done.

No, it isn't. Low pressure hydrogen has a very low volumetric density. High pressure hydrogen has a low gravimetric density. You either lose physical space or weight capacity.

I don't know how much they cost, but I know they weigh about 25-30kg for every 1kg of hydrogen stored. Nikola holds 80kg. The effective energy density of compressed hydrogen is only around 1,400Wh/kg not counting the weight of the HFC. The tanks are actually the safest form of energy storage...

You had an uninteresting rhetorical question. And interestingly you also lack an answer to your own rhetorical question.

How much does it weigh?

So, how do you explain the Tesla semi? Are they just lying to everyone?

I see that Gm has dropped the idea of FCV's for their own passenger vehicles. This is how I imagine a meeting going at GM. "We are going to halt our development of fuel cells in passengers cars and trucks." "Well, we spent billions on development, how can we recoup that?" "Hmmm, maybe we...

Interesting that Nikola is going to use GM batteries and HFC system meaning they essentially have nothing to offer. What innovation is coming from Nikola?

Most other companies have billions of dollars to invest in BEV technology.

Rivian has a built in flashlight that charges from the vehicles battery. I'd like to see that but with more options such as lanterns, portable air compressor, electric lighter, head lamp, etc.

Won't be an issue. The semi is coming out before the CT and it will necessitate the need for thousands of pull through chargers.

I would really like the whole rear to open. It would be great to be able to fold it down and have a mattress that is partially in the rear and comes into the rear seat area. Then your head would be in the cab area and you could still load gear in the rear without messing with your sleeping...

If they admit they were wrong about hydrogen and go all battery, then investors will drop them and they won't be able to do either. HFC's are their ONLY selling point. Otherwise, every single semi manufacturer and of course Tesla, are already way ahead of them. Tesla has all the autopilot...

Problem is, we weren't having an intelligent conversation. I have absolutely no idea what your point is or for that which you are arguing. The topic of the post was about Gates saying it wasn't feasible. I was listing all the ways in which it is feasible. And a few people chime in about how...

Yeah, you are right. They should just call it quits because BEV's might only cover 90% of the market. They should wait until it covers 100% or not to it at all.

The 300 mile range version will likely be about the same weight as a comparable diesel truck. That would cover 80% of all routes. The 500 mile range version will be about 4,000 pounds heavier than a comparable semi. That would cover the other 20% of routes which are long haul routes on...

You are talking about a fraction of a percent of the trucks on the roads.

Yes, that is exactly how cargo capacity works. If you are below 73,000 pounds in a diesel semi, and a Tesla semi weighs 7,000 pounds more, then you will still be legal with your normal full load. And truck drivers have a 14 hour duty period and can drive for as many as 11 hours in those 14...

90% of Semis on the road are under 73,000 pounds. So, that means a 9,000 pound battery won't impact cargo capacity very much at all. The average distance a semi travels is around 300 miles a day. So, range and recharging isn't going to impact revenues. Anyway, if they have a 500 mile pack...

Do you know that animal agriculture is the single largest contributor to climate change, water pollution, soil erosion, ocean dead zones, and deforestation?
