I can explain. You're thinking like a scientist, not a capitalist. Money will go into this tech because it forces you to be dependent on that charging system. They want that. It's better margins than electricity creation.

The only place I see liquid fuel being used is in commercial transportation, particularly in shipping and rail. Anhydrous ammonia would be perfect for shipping, and a nightmare anywhere else. That shit will fucking kill you in an instant, and those who survive just wish they were dead.

So it should only be used in highly regulated professional settings.

That said, it's still a wonderful fuel option for those settings.

This electrolyte swaps shit? I see it as an attempt to reuse all that gas station infrastructure all over the place.

EV chargers are all over as well these days, but they're still not anything near as ubiquitous and gas stations.

It's because people have this mindset that they might need to travel 600+kms twice a year, therefore they need a 700km range BEV because Despite 99% of their car usage is sub 200km ( and 90% is sub 100) it is somehow prudent to carry all that extra battery material and weight around unused

I think hydrogen makes sense in a few applications namely trucking and long range cars for the few who need it, though I would say it's probably better to invest heavily in trains and handle most shipping with trains then put the stuff on trucks for the last 50kms and stuff

Then what about trucking? Lithium is not nearly as energy dense, weighs a lot, and does take a significant longer time to charge than a diesel to refuel. If you don't believe me, look up the eCascadia by Frightliner. They are probably the current best option if you wanted a heavy electric truck, but they only get to around 200 miles with a load (for reference, a standard turbo diesel one would go around 600-800 miles and only take 30 min to refuel).

Currently in trucking, I've found that everyone kinda laughs at the idea of electrification (except on medium duty, that wouldn't be too hard, just overly expensive). Current electric motors are fine, it's just that the energy storage is nowhere near what is needed for actual use.

Yes, for most basic ev consumers current lithium is fine from a usability perspective, but from a cost one this might provide a much more useful alternative (assuming the cost isn't insane).

I just want a half decent second hand EV that will do 120 miles, for a reasonable price.

I can buy an acceptable ICE car for £5k, and it'll do that.
But at that price range, the only BEVs can get are shagged leafs that will do 50 miles on a good day.

The really annoying thing, is that 95% of my journeys are sub 50 miles. But I'm not willing to spend more than half the journey time charging midway through.

The idea of shipping liquid fuel in trucks and dispensing it out of hoses at special fuel stores is just silly.

I don't necessarily disagree with that but I hope you see that this type of infrastructure is exactly what we currently have and have proven to work.

It wouldn't be that stupid to reuse an existing infrastructure that is already built. The issue with our current fuel infrastructure is that it is moving fossil fuel.

Putting a charger on every street parking location will become disproportionately expensive.

Apparently, no one read the article. The primary application of this was for the military. The article is based on research done by DARPA. For military use, lithium ion batteries have way too short of a lifespan and the charge times are too long. Also, they can catch fire and burn for a long time, probably a real problem in a military context.

Flow batteries can mitigate all these issues and they’re cheaper and lighter. They can be made from inexpensive materials that are more readily available than lithium.

Given these benefits, it seems obvious that consumer applications will take off. The original researchers see an opportunity here and that’s why they formed a company.

Your cited lithium ion “20 min” charge time is for super chargers only, and in many cases is actually more like 40-45 minutes. Also, super charging is bad for the battery. In all other cases, you’ll be using an L1 or L2 charger which will take anywhere from 8 hours to 72 hours to charge a vehicle.

And, eventually, the lithium ion battery will lose its range as the battery degrades, making the whole car as disposable as that 3-4 year old smartphone you had to toss because the battery can’t hold a charge anymore. Flow batteries will keep refuel times to the same as they are today, and the material can be recharged up to 10,000 times, a huge improvement over lithium ion. And, the lifespan of your car won’t be literally glued and bolted to the lifespan of your battery.

It seems to me that we'll be living in a world with multiple solutions to the "fuel problem". In a city environment, maybe the lithium solution will be the best way to go, but we can't ignore that it isn't scalable for other uses. It's interesting to see how fossil fuels are powerful by the way they solve many problems at once; of course, after we built the insane infrastructure to support it.

We need every thing we got to beat climate change.

It has many benefits. Many. At least if article is correct. Doesn't burn. It allows for energy storage which is huge when you take into the account renewable energy generation. It might even allow you to store surplus at home. It's less weight which results in less consumption.
Also what makes you say that hydrogen failed. AFAIK perhaps for cars is not viable right now, but for bigger vehicles it might be very convenient.
Edit: also doesn't require huge improvements of energy infrastructure.

Nano desu

What makes a lithium iron phosphate battery an ecological nightmare?

That'd be cool.
