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...

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.

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...

I think yogurt is disgusting, but warm yogurt just sounds completely and utterly repulsive.

Still less dangerous than gas or diesel.

Actually, modern composite hydrogen tanks in fuel cell vehicles is the safest form of energy storage. Safer than gasoline, diesel, propane, and yes, even BEV's. That will change when solid state batteries become available, but today hydrogen is by far the safest. The tanks are so tough that...

Their cost would come out to at least 22¢ per mile before they even make a profit. Right now, the average diesel is 37¢ per mile. That means they need to be above 22¢ enough to make a profit, and below 37¢ to make it competitive with current diesel trucks. Of course, diesel truck manufacturers...

When I suggested he buy a used plane for less than 1/3rd the price, he balked at that and said he wanted new. He is very impulsive and doesn't listen. I think that is the problem. He says he surrounds himself with smart people, but the problem is that he isn't smart enough to listen to them...

The real irony is that a battery with twice the energy density of Tesla's current batteries would make hydrogen completely obsolete. If you could have 800 miles of range with electric, and 800 miles of range with hydrogen, why would you chose hydrogen? You are going to pay 5 times the cost for...

What is ironic is that I am an Aspie, and I generally do not read people well at all. But I could read him like a book. He came across as a BS artist and terribly narcissistic. And he spent money like it was going out of style. I think if I started a company that hadn't actually produced...

We are going to make hydrogen cheaper by having all of our 700 vaporware hydrogen facilities standardized. And we have a battery with double the energy density of what Tesla uses. But you can't see the technology demonstrated. Nor can any independent labs verify the claims. And we won't...
