Suraj,
Is it battery technology that is restrictive? Think of the battery pack as a tank where one puts in the gas called electrons. Now how you put it matters., if the hose is small it will take time to fill the tank and if the hose is big, the tank will fill faster. Alternatively change the tank itself.
Given the two statements above, I can turn around and say the infrastructure of putting electrons faster into the tank is not there. However the electricity grid is there and the electrons are cheaper some 4x cheaper than the gas (actually 8x, but let us stick with 4x).
So all we need is a big hose because we want to pump large number of electrons in same amount of time. The technology for that exists too. So what remains? Distribution outlets - in effect "gas stations". However each gas station today has gas, water and air and also electricity minus the big hose.
In an instant, the technology problem to me looks like a business problem. That is if I can convert 1 gas station per square mile to have at least one charging station that gives 50-100 miles in a 10 mins. charge., that is a start. However, turn the problem around once more, there are now @6000 charging stations across US. For example, Target superstores have on an average 8 charging stations. Free. So this can be leveraged.
Initially it may sound inconvenient, but turn the problem around again. A 25 gallon gas tank when full will take away 75-100 $ in an instant. So for some inconvenience upfront one can incorporate an electric car into a normal lifestyle.
Hence the electric vehicles are here to stay. Hybrids and plug-in hybrids are pass, they have been the stepping stones.
Now are we to say that the battery technology will remain static? Will the battery technology never improve? If in 1993 I would come and say that 1 Million HEVs/PHEVs/BEVs (hybrids, plug-ins, battery) will be sold within 20 years of time - I would have been laughed at.
Critical mass is gathering, @5% of all sales in US of personal automobiles are of the above category.
The energy density of today's batteries is far lower than hydrocarbons, much less fissile material. That is a fact. That is why it needs so much capital investment upfront in particular technologies as supercharging stations and battery swapping stations. It cannot be just parked in a normal gas station, plugged into a normal 120v outlet and expected to recharge in full in 5-10 minutes.
The cost difference to setup a "supercharging" station compared to a normal gas station is not much actually. See Target charges for instance. Why are they setup that way? It pays to have a well heeled customer in store than in walmart.
Instead, it requires Tesla to take on clean energy capital support and other means to invest the massive amounts in charging stations. It's not guaranteed that these investments will not be a huge loss to them if, for example, a new battery technology breakthrough enables superdense charge storage capability combined with rapid charging capability, that makes their charging station investments lossmaking, either due to redundance, or the need for further investments to modify the entire network.
Nothing is guaranteed in life.
. Cliche's apart, the part of "supercharging station obsolescence" is FUD. It is like saying that larger gas tanks and high octane ultra-clean 5 min/in/out Chevron gas stations are going to put the "gas stations" in general into obsolescence. They are still super-duper-charging stations.
Within the car itself, the constraints of battery technology is such that they cannot produce a vehicle for under ~$75K minimum (not counting the federal credit, which is an explicit subsidy to the buyer, but doesn't reduce production cost). The technology cannot be scaled down to produce a $20K car cost effectively (which is possible with IC engines), with a battery of similar energy capacity. It will take further economies of scale (which obviously isn't going anywhere) to pull down the costs. It's quite possible that e-car growth will be curtailed by various fears of 'Peak Lithium' due to supply issues, for as long as they depend on Li-ion technology, as well.
More FUD and you are running on fumes now! Here is why, improvement in IC engines have been incremental and the basic IC engine has not changed much. So the $20k car cost is basically subsidized for almost a century. You make the same case for batteries down below.
Further, lithium is immensely and easily recyclable. It is cheaper to recycle lithium, so if one purchases a $75k car and the price of lithium increases, it is like investment
. Keep that aside. And even though lithium is "rare-earth" it is very much available in earth crust. It is not "rare" as in "rare earth"., and if Li-battery technology improves then for the same charge, less Li is used which is again recycled every 7-10 years.
And why are we spending time on just Li- based recyclable batteries? What about Zn/Air (even lighter and denser)., Carbon nanotubes (ooh exotic) etc.
* explicit subsidization of the initiative by government partly by taxing IC fuels, and private funding sources.
* the willingness of early adopters - you're one of them - to pay the premium to support a new technology. There's nothing wrong with this - every new technology depends on early adopters' willingness to pay that premium.
Thank you for the second part, though it was an impulse purchase after surviving on corollas and 2nd hand sentras and hondas. For the first part, here is a twist on subsidies, a cleaner air quality saves several 1000s from the ERs. So the subsidies behind EVs is well spent. A direct cost comparison is tough, but even the IC was subsidized.
Further the cost per mile is actually cheaper in case of EVs (HEVs/PHEVs/BEVs) than ICs. And electrons can be generated using PVs/
Nuclear/Coal - yes clean coal!! (Theo must be saying Oh-mamma now)
Now the question is, is that the approach you want India to take ? The fundamental basis for doing so is the ability to generate and deploy capital in supporting the development and deployment of these technologies, and amortizing their costs over time to make them cheap enough. However, India is *not* a capital surplus nation, and the most efficient choice is to use technologies whose development costs have already been amortized, to rapidly build our labour skill base as well as internal capital base.
All the more reason for India to go the hybrid/diesel., hybrid/NG way and then to EV. Skip a generation of gas engines and directly jump to EVs. The ranges are very smaller in India and Gujarat and MP already have 24x7 electricity to a village level. Further, India is not lacking in Solar power or even coal. And one does not need a hi-fi battery swapping machine - India can harness that labor.
There is no "vision" required here, just a will to do. For example, do you see 2-stroke scooters/bike on the road? The moment Hero Honda said that it can do 80 Km/Litre, all the 2-stroke engines were going to go the way of DoDo (it is a niche now as I hear).
I saw the first CFLs bought by - drumroll - Indian consumers. Why? To reduce the electric bills.
The auto-rickshaws does not require a very high density Li-ion batteries, they can do with some low density ones which while the fellow is taking a nap can be either changed or charged. Of course hybrids help the range anxiety. The savings in the air pollution itself will be immense.
Problem is that the technologies are seen through "western" eyes and not the "indian" eyes. For example, you will find "generators" in all shops in Hyderabad - this are not some high funda diesel electric generator - this are Lead-acid batteries in series kept under the chairs/tables which will at least keep the lights up for a while. And li-ion batteries are already replacing them. In fact in Bihar you will find low to high quality solar cells - why?
It is not about vision - again - it is about will to do something.
There are quite a few examples of unique domestic technologies (anyone remember the
skybus ?) that couldn't make it simply because they required capital, technology and willingness to absorb risk. Please read about the Skybus - it's a very good example of what happens when we attempt to develop technologies without the capital and technological base - the result is a project that's underinvested in, and gets shelved after a single accident because there's no capital willing to risk such early losses to carry it through.
There is no risk taking - but if you look at the skybus - it is costly - setting up the concrete piers to hang a bus with humans in it and move it at the speed of a running horse. Scary. Costly. Should not have been attempted in first place - because it just does not make sense.
Even the LCA or Arjun MBT faces the same problem - ADA/DRDO works so slowly and painstakingly because they're limited by the amount of money available; one crash and DDM will be screaming 'stop the project and import!'
They are defense project and will not comment on it. DDM is a #paidmedia anyway.
The best way to avoid that is to have enough $$ in hand to bear the risks associated with developing new technology, and pay to train labour, develop, licence or steal technology needed, and put those two to work, and be willing to face a lot of failures. The easiest way to generate capital is to aggressively use technologies whose development costs have been amortized, enabling us to pay only usage costs, and save the generated capital.
Here is my example, try to setup a private initiative in Hyderabad with a capital base of say 1 Cr (peanuts) (and outside of It-vity)., a bunch of goondas will show up with their Hapta. Everybody and incl. your neighbour will scream at you for "profiteering" and "making use of the labors sweat" even before the MOU is signed. Then there are a range of Sarkari babus to satisfy. After that there are the CONgis with #pappus in their pants. Then there are a range of bank babus to satisfy. This is again in Hyderabad. Better to enjoy Golkonda fort and faluknama and beat back a hasty retreat. Assuming you cross all that, you have to source material and machinery.
Heck just open a samsung phone shop and ask everybody around you to become a doctor or an engineer.
Business is willing to bear the cost and take the risk, get the damn government out of the way. Goes back to my point on Guj. and TN being better states when it comes to business friendliness.
