I don't doubt demand is building, but it is not likely they would combine charge stations with traditional fuel stations, and I can't imagine a charge station would be profitable.

I don't see why you wouldn't combine charging with selling gas while there's still a significant demand for it.  Existing forecourts are going to have to change their business model in some way as the revenue from selling petrol and diesel declines and, judging by the area devoted to retail shops, restaurants and parking (I even noted a nail bar at one new site) it feels to me as if the developers have already seen the writing on the wall and are betting that tenants will pay a premium rent for a supply of potentially hungry, thirsty or just curious travelers with even 20 minutes to kill.   I'm just a bit disappointed that they aren't going a bit further and showing the public that the charging infrastructure is on the way.

 

At the dawn of commercial aviation, you probably wouldn't have dreamed that airports would turn out to depend on retail for a large part of their profits.

I can't stand him either, first and only time I watched him, I managed about 2 minutes and he got a thumps down and bye-bye.

Again, I do not see why anyone in an urban area would interested, at they will be generally be charging their cars at home. I'm in Bangkok and there seem to be quite a lot of charging stations in shopping areas. 

 

Pumps typically do not the area for much dawdling, particularly in urban areas. And as there are often lines, people will have to stay with the vehicle. Shopping centers make more sense, but you have to have self-service stations that accept credit cards and whatnot for payment.

In urban areas, the pump's bread and butter are daily drivers. Who would trade with them? Virtually everyone buying EVs are charging them at home. 

 

In rural areas the pumps are dependent on longer distance drivers and what few locals they have. People driving long distances are not likely to have EVs. 

 

The time issue is not insignificant. If you have a 12-pump station, you'd need 36-pump station (+ or -)  to put the same number of vehicles through. 

 

And you still have to burn fossil fuels to charge the batteries. 

You're assuming that battery charging times will remain the same and that renewables aren't steadily increasing their share of the electric power market

No, I'm not assuming that. 

 

I am assuming that as the percentage of EVs grow, a lot more grid power will be needed, and barring some groundbreaking new technology, existing renewables will be mostly useless for this in urban areas. To much power needed in too little area. 

 

Even if you get the charge time down to zero, I do not see any significant demand for e-pumps in urban areas where people will likely be charging there cars at home. 

 

No doubt you see things differently.

Charge time to 0 maybe can be but electricity in is electricity in . To load 50kW of battery power ( electric cars have batteries of 30-80 kW ) to load in 1 sec you need 50kW * 3600 second is a 180.000kW load , or simply said , a complete powerplant , only to charge your car . It creates huge powersurges since the grid can't take that kind of jumps up and down . ---> meaning , even if you dream about that and the battery can do , it will not happen .

It is much better to charge slow , much less influence on the grid . This all comes to a behavior change , petrol : drive your tank low and go to petrol station to fill it up again and drive again the same thing . Electric , most people drive lower distance 99% of the time . So when you drive like 50-100km in a day , you can easily come home , put in in your home at standard slow charge and it will be ready for you filled up again . Only if you cover 300+ km in a day , for more days after each other , faster charging is needed .

If it is some kind of smart grid , then the electric charging can be coupled to see which car needs the most , at what time , so the influence on the grid can be much much lower .

This said , you surely need extra electric power from the grid , since the electricity does not go in that wires from nowhere .

Further to this:

 

I have two electric cars. Fantastic! I will never have a petrol or diesel car again.

 

Earlier this year, I twice drove from Phuket to Bangkok and back again.

In both directions, I stopped three times to recharge to 80%. Each charge took less that 30 minutes and while the car was charging, I took the opportunity to go to the toilet, stretch my legs, have coffee/lunch/dinner - whatever. If I had been driving an ICE car I would have stopped the same number of times for the same lengths of time.

 

I don’t know about the availability of charging stations on other roads throughout Thailand, but Phuket to Bangkok is not a problem. Note: The online info about charging stations is not really very good and annoyingly confusing.

 

Charging when out and about: 
There are three levels of charging: Rapid, Fast and Granny. Granny refers to the slowest method which is simply plugging into a normal domestic wall socket. Charging can be done at some PEA offices (rapid), some petrol stations (rapid), all MG showrooms (fast and rapid), some hotels (fast), some shopping malls (fast) and stores (fast), and I even came across a restaurant that had several fast chargers. In my experience, almost all hotels which don’t have a charging station will allow you to plug into a normal domestic socket and charge overnight. Only one hotel refused to do this.

 

Cost:
The fast chargers at shopping malls and hotels offer charging for free. Smaller, cheaper hotels sometimes charge you about 3 baht per unit for granny charging. The rapid chargers at PEA and petrol stations cost 4 - 4.5 baht per unit.

 

 

What EV's do you have if you don't mind me asking?

No doubt you see things differently. 

Why do you think that a power plant has to be located near an urban center?It's not a matter of seeing things differently but facts. New York City gets part of its power from Niagara falls, which is 370 miles distant. Or take the case of Texas. Its big wind power projects are located in the sparsely  western, northern, and southern portions of the state but sent to the densely inhabited parts of central and eastern texas. That's hundreds of miles. 

And the latest HVDC power lines can transmit current about 600 miles with only a 1.6% loss of power.

Another mitigating factor is that most home charging can be done in the evening when power demand on the grid tends to be a lot lower

The first thing to note is that long-haul flights by large aircraft are not going to become fully electric any time soon. Certainly not within the next 50 years – and the jury’s out as to whether that will even happen this century. The reason is energy density.

 

The power density in aviation fuel is high, in the neighbourhood of 12,000 watt hours per kilogram. A lithium ion battery is only in the region of 200 watt hours per kilogram.

Must be why he has an engineering degree  then

You have just  proven yourself to be  ill  informed , hes  none of those and regularly promotes it often castagating the govt  over vaccines  and lambasting Trump. Your head is stuck  so  far up your electric  backside you make  yourself  look stupid.

Electric aviation , even the industry is seriously looking about that . It isnt there yet , but even the industry says that in relative short time frame (10-15y) short haul flights can be done electrical . Long haul is not on the table yet , unless they find other ( aka much higher energy density , way beyond what is known now ) types of battery.

Saying like it isnt there since only tests are done and the airplane can only do 9 person for 250 miles , remember that 15y ago electric cars did not exist ( well they did 100y ago ) , let alone with a range of 100 miles . Even 5 years ago 200 mile range was about the maximum . Technology is evolving fast , and yes it will take a few years , but it is way closer then you might think .

There are many many hurdles , for all this electrification of transport , but it is fast moving in . It will create other problems ( like the charging capacity , grid not up to date , ... ) but just see the speed it is evolving , and you see that within 20years , a whole lot is gonna be very different .

Thanks for your information.
I’m gonna call Norway immediately, tell them they are really dumb and have them contact you. 
 

Norway has mandated, by 2040, all civil domestic aviation in will be electrified aircraft. 

By 2030, the first ordinary domestic scheduled electric flights will be in operation.

Whereas this Bogan's failed predictions about Tesla make him look intelligent?

50 years? Anything else from that crystal ball to report?

Maybe it has a filter that keeps out the develop of such technologies as structural batteries.

And keep in mind that fossil fueled engines are a lot more inefficient than electric powered engines.
