Thread: Saving the World with hydrogen just took a step closer

BMW iX5 Hydrogen model nears production for 2022 - Automotive Daily


6kg of hydrogen. Refuel in seconds (IF AVAILABLE ) 500km range is a bit low given that bit?

Towing but only a light duty off road car that cost to much for me anyway

2022 short production run by BMW is a starting point. As bits are from Toyota a Hydrogen Landcruiser might beat Landrover to the line?

LR have said EV doesn’t suit most of their range of vehicles,so it will be interesting to see what they do.

Toyota have been in bed with Yamaha for quite a while now developing hydrogen engines.

I thought this looked wrong so did a google and this came up.

1 kg of hydrogen is equal to 1 gallon of gasoline in btu equivalent. MRE electrolyzers require 48 kilowatt hours (KWH) of electricity to produce 1 kg of hydrogen.

So it will go 500Km on 6 gallons . That IS impressive.
More like 60Kg of Hydrogen methinks. And that would take BIG tanks.

The Mirai is a fuel cell vehicle. Hydrogen theoretically holds ~33.6KW/h/kg, so that's 201kw/h theoretical. Current best case fuel cell efficiency is about 45% leaving 90kwh.
A Tesla model 3 is rated at 5.1 miles / kw/h by the US EPA, so that'd give you 459 miles or 734km. So not out of the realms of possibility at all.

Now the energy required to *make*, store and transport that 6KG is something else again.

That’s the fun of the colour system..

Blue vs Green

Then there’s the first Hindenburg moment and the tech will disappear.

AFAIK the Hindenburg burnt rather than exploded.

The memorable LNG and LPG incidents were explosions but didn't bring the about the end of either.

There was the LNG ship that blew up in the Atlantic off Africa many years ago and the flash was satellite detected. No one walked (or swam) away from that one.

Was being reported for a week as Sud Efrica testing a nuclear weapon, with appropriate alarm bells.


And years ago there was the LPG semi tanker that blew up one night on the Hume after the driver had got out and stopped traffic beforehand. Was near Killmore, but no one was hurt.

By chance I actually saw the flash of that in the sky from the Bellarine and heard the boom a long time after, and have a newspaper clip with a pic of the tank that is spread nearly flat with wobbly baffle plates pointing skywards.

In any case it seems that a certain amount of premature death is quite acceptable to keep things 'moving along' these days.

cheers, DL

"The Mirai is equipped with a set of three light and strong hydrogen tanks made from high quality laminated carbon fibre reinforced plastic. " its compressed at about 280 bar I think. "

"

• new Toyota Mirai has increased the world record distance to over 1000 km
• After breaking the record, Mirai was refuelled, ready to go again in only 5 minutes link

the average fuel consumption was 0.55 kg/100km, with Mirai being able to store 5.6 kg of hydrogen.""
Not that Australia has a lot of hydrogen refilling stations yet

The new tanks are soo much better than my steel diving tanks. I wonder if I could? I bet I cannot get one for Air yet sadly. Ligher, stonger and much more AIR capacity- DOH

I think more tellingly are the tales of oil slicks from tankers and processing plants that barely raised a blip on the tech radar of the petroleum system.
As far as I can tell the oil industry still thrives. This only shows that the level of care that the general population has for disastrous incidents is quite low .. if it exist at all.

Only things that seems to matter is /price/speed of/convenience factor. If they all coalesce into a usable system .. even if it blows half the world to smithereens and causes total global war .. people want it.

Wasn't there a total failure of the gas system here in Vic about 25 years ago, and you didn't have piped gas to your house, let alone LPG for vehicles(at a time when Ford were selling LPG only options for the Falcon too).
At the time I recall people making all sorts of noises on the issue .. Now, ask anyone if they remember that saga ... answer will be 'Oh, yeah, jeez I forgot about that one'.

it seems that 99.9% of the population has very short attention spans, and it seems that the percentage is growing and the span of the attention is getting shorter.

Any mention of a future full scale nuclear meltdown of any systemic hydrogen process is almost certain to be via TikTok, or Instagram or whatever other future 10 second news outlet app that is surely to be the one to have .. and will be forgotten a second later when the next news feed is pushed through.
