Glad you enjoyed it.

Great video as always, but with minor correction; at 8:06 you say 6kg each. It's 6kg for both tanks together. As it is, the efficiency isn't anything to write home about with 500km/6kg, but not bad for a pretty large SUV. The average current price of H2 is about $25/kg in the US. It will certainly fit the needs of some.

Very clean water comes out of the exhaust pipe and turns into beautiful black ice on cold winter days, even when it is dry and sunny... Sounds amazing to me. More power to them.

Impressive! I remember doing a final work at school about hydrogen fuel cells back in 2006. If we can manage the production/transportation of H2 in a green way, this will become interesting

Yes, the tech is very interesting

Nice video, thanks. There are 2 advantages that were not specifically mentioned: (1) the hydrogen car is relatively light compared to a BEV as no large capacity battery is required (this can easily save 400kg of weight). (2) The energy density of H2 is very high, which results in a decent range (500km for this car) for just 6kg of H2. Only recently, some BEVs can do 500km. Of course there are downsides too. At this moment there are hardly any H2 filling stations, hopefully this will improve over time.

It's not that much lighter than a BEV car. It's the same weight as a PHEV X5 so close to 2.5tons. And range is also over 100km down on the iX.

if I look at a hydrogen charge map of the UK I see two: one by Heathrow Airport-where rapid fuelling of airport vehicles running 7x24 makes sense, And a bus depot in Wales. Again somewhere where a fast turnaround is justified. but every day commuting, the fact that the vehicles are idle, most of the time means that low speed charging at home and work is perfectly suitable. As an example, my employer's California office has covered parking for EVs only where every parking bay has a charging point-probably about space for 60 vehicles. If you own one, you can drive to work down the carpool lane, park it in the shade, have it charged during the day - and then as the time to go home approaches, turn the air-conditioning on while still unplugged so it is nice and cool when you head out for the evening traffic jams. You can criticise BEVs for range and time to charge, but manufacturers can improve it, and for most commuters, those long journeys are an outlier

They say it was about the same as the PHEV but less than the iX. If it was less than the PHEV, they'd say it. So let's take the upper trim of the PHEV at 2552 kg and the iX weighs 2566kg or 14 kg more. Of all the examples that exist (Mirai, Nexo), they are about the same as a full BEV in weight. Some are hard to compare; for example, the Mirai weighs more than a long-range model 3 but the model 3 has much more interior space because the energy density of H2 may be high, everything needed to make it back into electricity to drive the motor isn't. Basically, they weigh the same because they both have the same drive train/electric motor and you're substituting the 400kg battery module in a BEV (which usually includes structural members); for the tanks (~135kg), the fuel cell, (~70kg), the hybrid battery (~70kg), plus all the auxiliary systems including air pumps, condensation pumps, filters, etc (another 45 kg), plus extra body reinforcing above the hydrogen tanks (~25kg). So about 345kg. Because the iX5 accelerates so fast, I suspect it has a much larger hybrid battery than a Mirai's 70kg hybrid battery, maybe about 120kg.

as an engineer, I find this fascinating. However, I would question the value of BMW investing lots of money in this given that there are so many problems in pure BEV models, battery manufacturing, at scale, integration with charging infrastructure, etc. Those are all things where Tesla are ahead -something they have managed to do by neglecting foundational issues like manufacturing quality. The Japanese car manufacturers put a lot of money into fuel cells and now they are way behind on BEVs and having to struggle to catch up... The more people who install household charging points, the more-high power public charging points get installed, the less compelling the arguments in favour of fuel cells as a mass market product becomes. I can see the motivation from the ICE manufacturing supply chain, and from the fossil fuel industry as the "blue hydrogen" story keeps them drilling up carbon from the north sea a bit longer -but charging a car battery solar panels is, once you got those manufacturing costs out the way, a better long-term story

Hallo Sir, bmw had lounched this system at 2000 with 750 il 12 cylinder. They build 20 cars to show very simple system and rjns. Only the German government block this big advantage to arise the new standard in the market. And Germany has the most experience in hydrogen in market. You now Hindenburg aircraft 100 years ago. They drive two Years with own line between Germany and south America.. Every week. No accidents in hundreds of flights.

dont rely on TrueZero to provide hydrogen . last couple months all stations were unavailable here in the valley, and currently $36 a kilo

To give a numerical answer, they say it weighs about the same as the PHEV which is between 5512 lbs and 5627 lbs vs the iX which is 5659 lbs or 2.6%-0.5% less.

I see they still are not generating the h20 which is possible. I'd imagine the government wouldn't allow it as it would run on water and they wouldn't be able to tax it.

Where does the hydrogen come from? How far do you have to drive to get to a H2 fueling station (in order to spend 3-5 minutes refueling)? How much does the hydrogen cost, versus gasoline?

@bmwblog

A very complex question because hydrogen can be produced in multiple ways. It can also be difficult to refill. In Antwerp, it's fairly easy. In other places, not yet. Hydrogen cost is high today in Europe due to the energy crisis.
