> it could release highly toxic hydrogen sulfide gas. How bad is it in real world conditions? Because from what I'm reading it's not the "it makes you sick" kind of toxic, but rather the "it kills you in seconds" kind of toxic.

Out of curiosity, What is the wh/kg for petrol?
Wikipedia says 13000 Wh/kg, but you have to keep in mind that due to physics, wear considerations, and emissions regulation, most cars are only 20-40% efficient. At a 20% efficiency, that's 2600 Wh/kg. This is further constrained by gear ratios, meaning not all power is available at all times.

Now if they scale it up. but at any scale that makes sense economically you can get suffocated by just about any gas you can think of. Like helium or hydrogen.

If it could only reduce the weight of current EVs that would be a win. Most electric vehicles weight 1000 lbs or more than their ICE counterparts, and in the extreme case of the Hummer, the total weight is over 9000 lbs. Vehicles seem to be continuously ballooning in size, so whether that continues or eventual legislation forces more reasonable sizes, higher energy density would be very welcome.
When will this meme die? A Model 3 is very comparable in weight to an Audi S3. The Hyundai Ionic 5 is comparable weight and interior volume to a Toyota Rav 4. The Hummer is a monster either way and is not a good sample.

This will be neat if it works but really there isn't going to be a huge market for 500+ mile cars vs the cost savings of getting a 300-400 mile car. The exception might be road-trippers and people who do a lot of towing but I suspect that is a much smaller population than people tend to think.
Americans don't buy cars anymore, though; not really. They buy ludicrous gigantic heavy pickups and SUVs. So what we're really talking about is getting decent range into oversized pickups that their owners want to accelerate like sports cars and still have a nice air-conditioned interior even when it's 150 degrees on the pavement due to climate change.
Unfortunately the way this is calculated is absolutely fucking retarded. Basically, the larger the wheelbase of vehicle, the lower fuel efficiency the vehicle can get away with.
This is why these fucking things keep ballooning in size, have a dogshit turning radius, and are causing an epidemic of frontovers and backover accidents killing or injuring thousands of children every year because there’s no up close visibility.

Old small trucks can actually command a premium because of this bullshit. Very few people actually like these huge stupid boats, but there’s just nothing else to buy when you need an actual work vehicle.
Please consider contacting your legislators and putting this on their radar, and keeping it there.

The Model 3 is 14% heavier than the Audi: https://www.edmunds.com/car-comparisons/?veh1=401999985&veh2...
And the Ioniq5 is 35% heavier than the RAV4: https://www.edmunds.com/car-comparisons/?veh1=401958795&veh2...

Think of the whole spectrum of EVs, lighter weight e-bikes, scooters, skateboards, or long range e-bikes. Electric aircraft start to become feasible.
Much more flight time out of your toy drone, multi-day battery life for your phone or laptop.
Energy storage in off grid setups becomes simpler, or more capacity in the same space.
Etc. etc.
All that provided this new design could function as a more or less slot in replacement, or better, for current lithium batteries in terms of manufacturing, cost, and what not.
