Electric Vehicles

Seems like I've heard about H fuel cells for a long time. If superior, what is the delay to market?

This is what a quick search came up with. Seems mainly cost.

"Hydrogen fuel cell vehicles (FCEVs) are delayed primarily by a severe lack of refueling infrastructure, extremely high fuel costs, and low energy efficiency compared to battery electric vehicles (BEVs). The limited network of stations, which often experience maintenance issues or shortages, makes daily use difficult, while high production and transport costs for hydrogen make them less economical for consumers."

Hydrogen distribution and a cost/energy effective electrolysis method. Hydrogen powered cars are available today in select markers however fuel distribution is the hold back. I posted a link in this thread a couple of years ago that a sea water electrolysis method had solved the hydrogen generation issue but you still have distribution issues like every new energy doubt that isn’t a Mr Fusion small form factor nuclear reactor.

Be easier to bring back the overhead power lines and directly power the electric public transportation like America used to have and other countries still continue to use.

Ok so hydrogen has 100x higher energy density than the readily available lithium ion battery technology and as I stated above there are sea water electrolysis methods maturing now to address fuel generation capacity and costs. Infrastructure will be the driver.

 
You've been wrong before, right?
I thought I was wrong once but I was mistaken.

I’d submit you’re wrongly equating ease of use of existing technology over new technology development. If the new technology has merit and is cost effective it will displace current technology during a period of overlap. That’s all there is to it.

“Why do we need this fancy nuclear power for ships wind power has worked just fine for hundreds of years!” - mcdiddy probably 😎

on what scale/end goal?

because your assumption drops a lot of the functionality that a new/bigger Hydrogen system has.

the Hydrogen system would be a "1 for 1" replacement of the current petroleum based fueling. instead of going to get gas you are buying hydrogen. that would allow drivers to go wherever.

your proposal on the old system of power delivery limits use wherever those lines are in place. I don't know for sure but I can't imagine one can simply just tap into the existing overhead lines to power vehicles on the move. I am willing to bet that is a separate, parallel, system to the overhead lines. even assuming we have the capacity in our electrical system to do that.

LOL.

I probably am wrongly equating things.

Your statement starts, "if the new tech has merit and is cost effective"... Seems to me both you and KptVFL identified cost effectiveness as the limitation. With cost effectiveness being a limitation, it makes the "then" part of your statement invalid because the "if" part of the if/then isn't valid.

What say you?

I say what I’ve said already it’s still a work in progress. I fully expect it to get solved and a BUNCH of money is getting thrown at it because the upside is simply enormous. As a raw material fuel generation source look at a globe and see how much of the earth’s surface is covered by water.

BEV’s are an intermediate point. They have a place they are not the be all end all. Personally I’m not a fan of them as a BEV alone vehicle. But BEVs with a considerably smaller battery are the design starting point to add in a hydrogen fuel cell and hydrogen source. And… these cars do exist today they are just not widely available. In fact they’ve been around over a decade. It isn’t prime time yet.

Ok. Here's where I see the convo so far.
1. post discussing the poor performance of a battery powered bus
2. straight piping the electricity to the vehicle was done and is still done other places. That's better.
3. H fuel cell is even better.
4. H fuel cell is held up by cost, infrastructure, etc.
5. Let's go old school since those holds exist.
6. If/then
7. if isn't here so then isn't either.
8. H fuel cell is work in progress.

I am not anti fuel cell or anti battery. I am pro what works and works today and accepting the condition that we are moving away from ICE (motor not thugs). As far as I am concerned, internal engine is unmatched right now.
 
downtown-ish bus routes.
even on that scale its tough to pull off.

This article doesn't take an objective opinion of the Atlanta street car, but it does present the facts.


Atlantas street car came in about 30% over budget, 98 million vs 74. costs about 50% more to operate, and generates less income than they thought.

it was/is a huge disruption to downtown, and suffered from poor planning. The only other public transit lines it really connects to run roughly parallel routes to the street car. they had to go and create a separate bus line to connect it to the nearby train stations because the ease of access wasn't great.

I think if you are wanting a new technology to succeed you want something that will be more accessible to the masses to really prove out the tech. I don't think relying on government programs is going to be enough to really establish any new tech.

But I am not talking about new tech, and income generation estimates. I am talking about existing bus lines, known routes, known revenue. Surely there are overseas companies that are producing electric buses for other cities. The infrastructure is all in the electric lines.

I don't think it is apples to apples, Louder.

Then just go with dual fuel NG/gasoline until the new stuff is ready for prime time and call it a day as that is the best old school available!

The technical article I linked for hydrogen sea water generation put it at TRL 3/4 which gauges the technology as deeply into the development phase and lab validated and almost ready for a viable technology demonstrator. The vehicle itself is clearly TRL 10 you can go buy one today.

You're a real piece of work. You know that? Idjit!

Funny story about NG ICE. I renovated a property a couple years ago. Last thing was to get the gas service restored. Dude came out in his F250 company truck. It's idling 10 feet away from us as he goes through his process to get the meter turned on and check for leaks. I say to him, it's kinda of funny the NG company uses diesel trucks and not NG. He says it costs too much to run NG trucks so they just stick with diesel.

Eh I’m not so sure I agree with his statement but it probably requires an up front capital investment they likely didn’t feel they needed to spend. Which I think is reasonable. I’d guess the recurring vehicle and fuel costs would be largely a wash but admittedly that’s just a guess. Both ICE types are quite mature.

Yeah, he referenced the conversion of existing fleet and the cost of an NG truck compared to diesel.

Was only 3 years ago. Cant be that much different than now. Have you priced NG F 250?

I have zero interest to even consider it since I can drive in nearly any direction and find a diesel and gasoline fuel station within 5 minutes. I think most all of this stuff for residential use is rather silly and just statement driven since most of us don’t have a fleet which gives us economies of scale for common maintenance and self fueling stations.

Ive always though NG made a lot of sense for farm equipment on big farms assuming they could generate enough HP.

I’d guess for farm the off-road diesel still rules the roost unless the bastards have mandated low sulfur and DEF regen engines on those vehicles too. Then everyone needs to just be fired.

Lol. Get off my lawn.

And not directly related to the conversation but since we're talking about farming and farm equipment, I also thought making farm equipment autonomous would be much easier and safer than making Passenger cars autonomous

the atlanta streetcar is exactly that. it relies on overhead lines. it still requires completely new infrastructure.

ND40 may understand more of the actual electrical side of things but the power in the transmission lines is probably not directly usable by the streetcars. you would need a series of transformers to convert it to a usable system, at that point you can't put it back into the existing lines. you will need a second power line to run the streetcar.

I think you lose a lot of flexibility when you tie a system down to the powerlines. just today in Atlanta I saw a MARTA bus pass some vehicle pulled over on the right. your system wouldn't allow for that. you need a system that is completely separate from the road to really allow a tethered system to work.

funny enough Atlanta is proposing an autonomous system that does just this thru two very fixed points with a completely separate "road" for it to run on. Its EV, but I don't think they are doing the power lines. we will see how/if it works out.

Well fewer kids to run over in school zones and fewer pedestrians to hit in crosswalks for sure.

GPS steered farm equipment has been fielded for decades. In fact a work buddy had his own business doing add on systems until all the big companies pulled the technology in house and he could see his revenue stream drying up. So he found a sucker to buy the company and went to work for the man.

With or without rails?

Do you think in cities where electric bikes are currently used, they don't navigate around obstacles when needed?
