I don’t get it. For the average consumer, EVs as they exist right now are fine. Charging is generally 20 mins every 2-3 hours and only on road trips. Charging an EV at home is a trivial technical challenge. I understand that there aren’t chargers on street corners, but vehicles are rarely parked more than 20 feet from some kind of electrical service.
The idea of shipping liquid fuel in trucks and dispensing it out of hoses at special fuel stores is just silly. Rolling out that kind of infrastructure is unnecessary, and hydrogen has already showed that it doesn’t work. We only did it with gasoline because there was no other way.
I can see liquid fuel being useful in certain applications, but for the typical consumer, BEVs are the way to go.
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.
You are not completely incorrect here, but the capitalist side of this entire industry shifted to obtaining the rights to the raw resources a long time ago. There’s a reason Tesla and Toyota have been snatching up mineral rights via acquisitions for years now. They want the entire supply chain, not just the proprietary means to deliver the product.
But that’s the supply chain for the vehicles, not for the fuel. One of the best parts about BEVs is that if a new better technology is invented tomorrow, as long as it continues to use electrons being pushed around, all the infrastructure will continue to work. I don’t care what companies or governments try to do, I can still plug my car into the wall.
There’s money in hoarding the lithium, but not the kind of printer ink/razor blade money that you have with fuel sales.
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
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.
I test drove a Leaf and honestly it felt bad brand new. I got range anxiety just taking it on the highway and back to the dealer.
So far, I think Tesla has a monopoly on practical EVs. Say what you will about the cars (or their leadership) but the charger network they built out and having ~150 miles of actual range is hard to beat in an existing product.
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.
What I don’t get is how gasoline even has an infrastructure. It’s delivered by trucks. If you replace the manufacture and dispensing with new equpement, what infrastructure are you left with? Trucks?
Fossil fuel is so energy dense you can get away with pretty much any way to distribute/dispense.
what infrastructure are you left with? Trucks?
Trucks and most importantly thousands of strategically located gas stations. Even if you distribute a different kind and less dense energy I would argue it still makes sense to have spread out stations all over the place.
If we want to keep using our existing roads and highways we will need those stations even if they distribute something entirely different.
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.
Why do people get hung up on the supercharging stop they would need to make 2-3 times a year and ignore the 40x a year they currently go out of their way to wait in line for cheap gas at Costco?
Also, there are Teslas with 250k miles and 90% range. The batteries can already outlast their vehicles, and finally, recycling batteries is possible and a lucrative business.
I have a minimum of eight ~500 mile drives I have to make in a year. I drive a plated and insured golf cart for most of my trips but theirs no way I’m tethering myself to a power cord when I can, with great confidence, pull over and fill my minivan in ~5 minutes wherever I’m at once I get to a quarter tank of fuel. I also end up with several trips a month where having a minivan is convenient as hell. I’d love to be able to reasonably jettison fossil fuels at some point so I don’t understand the criticism towards discovery, engineering, and evaluation of a broad spectrum of solutions and applications.
Most vehicles stay parked for at least 12 hours a day. The average American vehicle is driven 35 miles a day. A standard 15A 120V outlet would do fine. They can also be set to only draw power during off peak hours when electricity is cheap and plentiful.
I think running a few dozen feet of wire is easier than inventing a new kind of fuel.
Most people don’t live in the US, also a lot of people don’t live in single family homes and park on the street. No garage means you need to install lots of on street chargers.
Which amount to basically extension cords with relays. All the tech for charging is already built into the vehicles. Most people could live happily with just 20A at 240V.
I don’t see how inventing and rolling out the infrastructure for an entirely new kind of fuel/energy storage tech is easier than just running some more wiring. If they charge at night when the office building/apartment/transit energy use is minimized, it won’t even put that much strain on the grid.
And you get to keep all the existing benefits for single family home people. Sprinkle in some vehicle to grid, and it gets even better.
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.
Technically, yes. Most of the time. Beyond that, no. It isn’t good enough for a great deal of people. Lithium batteries are hard to recycle, hard and expensive as hell to replace, give constantly diminishing returns as range goes down every year it’s owned, people in apartments can’t charge them without going to charge stations that are more expensive than gasoline, and range anxiety is very much a thing that prevents anyone from exclusively owning electric vehicles.
Transportable fluid that holds more density than lithium (which means vehicles won’t be so heavy which saves on a lot of issues) and doesn’t require a nationwide restructuring of the electrical grid system seems like a way better idea than adding an extra 1200 pounds of battery that will cost $12,000 to replace when it goes bad.
I only wonder if the liquid can be safely disposed of or recycled/sustained. Regardless, setting up a system to use this would take two decades to really implement and we should have solid state batteries before then that should get rid of quite a few of the several shortcomings of lithium batteries.

Hydrogen is also important in construction when utilities aren’t typically present.

EVs are fairly new while ICE vehicles have been produced for 100 years. This is why you can get an ICE for $5k but currently not an EV.

It all relates to the density of energy in fuel.

Putting a charger on every street parking location will become disproportionately expensive.
Most vehicles stay parked for at least 12 hours a day. The average American vehicle is driven 35 miles a day. A standard 15A 120V outlet would do fine. They can also be set to only draw power during off peak hours when electricity is cheap and plentiful.
