Oh God. BMW’s Chasin’ CARB Credits, Too! 🙁

I don’t think so. They can get all the credits they need from the i3, and have a whole slate of PHEVs coming.

As Carlos Ghosn has said “everybody has prototype vehicles.” But “where is the infrastructure?”

BMW is even further the odd man out, using large Dewar of liquid hydrogen. The inefficiency is staggering.

10,000 PSI tanks will give most people pause. But liquid hydrogen, on freeways? In a performance car?

And BMW would what, build their own liquid hydrogen dispensing infrastructure?

H2 i8 makes for a shiny toy the press can’t resist.

EVI said: “BMW is even further the odd man out, using large Dewar of liquid hydrogen.” BMW is NOT using liquid hydrogen; it is using cryo-compressed hydrogen (CCH2), which is compressed gaseous hydrogen at low temperature and 350 bar pressure. BMW is using lower temperature rather than higher 700 bar compression to store the same amount of gaseous hydrogen in a smaller volumetric space. Gaseous hydrogen at low temperature and 350 bar pressure (-210 to -230 degrees Celsius) takes up less space than gaseous hydrogen at 700 bar pressure (-40 degrees Celsius). The cryogenic pressure storage vessel can keep the low temperature hydrogen “in the tank for a long time, even several weeks after it has been refilled,” and offer up to 50% more hydrogen storage capacity than 700 bar tanks. You might have missed it, but this was all covered in the following rather contentious article on InsideEVs: EVI said: “And BMW would what, build their own liquid hydrogen dispensing infrastructure?” Actually, BMW partnered with Total to recently open a hydrogen station in Germany that dispenses both industry-standard 700 bar compressed gas hydrogen (CGH2), and cryo-compressed hydrogen (CCH2) which allows for lower pressure and smaller tanks. “Cryo-compressed hydrogen… Read more »

Revomit all the marketing hype you want, sven. This was all covered:

Not only have the markets spoken, but BMW itself has spoken: When their own logistics are on the line, they choose electric. Because there is no point in them vape-and-switching _themselves_.

I take it that you haven’t put down a deposit to purchase a Mirai for yourself.

I apologize for using shorthand, and I stand corrected. The i8 uses ““Cryo-compressed hydrogen” at -210 Celsius, 5,000 PSI.

The liquid hydrogen was used in the BMW 745h.

5,000 PSI H2 at -210C would be… Safer?

Mechanical release would be 0.6 kWh / kg. Pretty sure anything it came into contact with would get really cold, quick. Kind of like a rose in liquid nitrogen. Shatters, if I remember as far back as high school.

I’ve seen the valve broken off an acetylene tank. It was not something I’d like to see happen on the freeway. Or any street, ever.

No problem ECI.

I remember reading about an acetylene tank leak inside an FJ Cruiser that exploded with the owner inside, after he decided to drive it out of the garage. It exploded not when he started the car, but when he used the power windows to let in more fresh air. Surprisingly, the owner survived almost unscathed, while the damage to the FJ Cruiser was severe.

you elon musk fanboys need to give it a rest; the fact of the matter is that many auto makers (other than tesla) are investigating FCEV technology. the number of auto makers doing FCEV research suggests to me that FCEVs will almost certainly end up in the *EV mix of automotive product offerings. i used to think that the idea of a battery/FC hybrid EV didn’t make sense, but now i am reconsidering: you could replace the ICE in a PHEV with a fuel cell stack, for example. this gives you a car that can be charged and run emissions-free for most local daily driving combined with an alternative means of emissions-free driving that can support long range driving with quick fill capability without requiring the use of potentially dangerous megawatt EVSE. however, the drawback to this is that a battery/FC hybrid would be more expensive than an FCEV, but the advantage of the hybrid approach is that you probably wouldn’t need as much refilling infrastructure than you would need if you had FCEV alone. FCEVs also work in applications where people are routinely driving long distances, such as long distance trucking. in this regard, i could see hydrogen filling… Read more »

When it comes to long haul freight, I can kind of see the point of hydrogen, yes. Unfortunately, margins are already slim in the industry and introducing a vastly more expensive fuel than diesel is not going to go down well.

There is a lot of research going on in batteries. If batteries get double the capacity for half the price within the next 10 years then hydrogen fuel cells will have no chance even for long haul trucking.

They already have no chance for long haul trucking. Natural gas stations are being installed along freight routes, and “hydrogen cannot compete with hydrogen sources.” Natural gas fuel cells win, versus any conceivable hydrogen distribution and storage chain, due to the Second Law- direct natural gas conversion will ALWAYS be more efficient than another middleman. Meanwhile, long haul trucking can deal with startup times.

Perhaps that’s true on whatever planet it is you live on.

Meanwhile, on Planet Earth, the collapse of this boondoggle is already well underway, with many “fool cell” car drivers complaining that the one or possibly two H2 fueling stations they were depending on to fuel their cars, have been closed for weeks or even months. Others complain that due to the very limited availability of H2, they spend hours in line waiting for a pump, or are limited to getting no more than half a tank full instead of filling up.

the problems cited in this article are just early stage technology problems. specifically, they are infrastructure problems which are operated by third parties.

the hyundai FCEV looks like a regular SUV…

Clinging to “fool cell” fanboi delusions has moved past the point of merely ignoring science and economics. It’s reached the point that it’s downright pathetic.

The hyundai FCEV that ain’t sellin’???

It’s no use arguing here. This forum is full of EV partisans; Elon has blown in their ears and closed their minds.

Yeah, it’s really sad how close-minded we are. We don’t believe in perpetual motion, either… and for the same reason. 😀

Thermodynamics works the way it does whether you believe in science or not.

When people hold that long to a bad idea, it is becoming more a human psychology study than an energy storage study.

I might have missed something for sure M.nocomment, but I dont think BMW I8 is near a full hauling long distance rig.
I guess hydroguru are more obscur than battery fanboy!
Their dream could only work in an unlimited ressource context and plentifull richness to everyone.
Sorry, but I not on your cult, because I have to pay my bill.

And even with infinite funds, hydrogen will still be less profitable. It’s an energy middleman; the energy-industry conclusion that “hydrogen cannot compete with hydrogen sources” is true on thermodynamic AND business grounds.

This aphorism was reached before anyone outside of e-commerce ever heard of Elon Musk.

NC: Hydrogen is DOA.

It’s an energy carrier and not a form of energy in and of itself. It takes energy to create. It’s also not very energy dense, so it requires additional compression or cooling to create useable densities for vehicles. Each of these stages introduces losses and significant inefficiencies, over BEVs.

There is a WEALTH of information about the inherent problems of creating, storing, and exposing fuel stacks, hoses, valves, tanks, pipes, compressors, etc., to hydrogen contained on the internet. Go read it. Basically, using exotic materials to control exposure to hydrogen adds additional costs to said infrastructure / vehicles, and limits reliability and increases repair costs. I should not have to repeat these facts for every anti-hydrogen post on this blog…

If you can’t grasp physics / math, let me be blunt: Large Scale Economics will NOT negate all the inherent problems with the fundamental physics of Hydrogen itself. So why even bother with it? Ask the Fossil Fuel Industry…

You Hydrogen Fanbois need to give it a resst.

“BMW says its i8 hydrogen fuel cell prototype has recently been taken out of service…”

Seems to be a trend for “fool cell” cars these days. 😉

Nah, Schwarzenegger had his Humvee conversion fail on him years ago.

Regarding sales: call me back when all FCV’s combined sales in the U.S. reach what a single manufacturer, Tesla, sold last year.
