Players like www.lithiumbatterywale.com and www.vmechatronics.com have solutions for lithium batteries for electric vehicles and focus primarily on efficiency which is a very important factor to consider. Apart from that they also have plans to manufacture batteries from the cell level onwards.
Well! the buzz word is EV now. But I am quizzed to understand that how all the EVs are going to get power to recharge them? Still you need Coal/Gas/Thermal power plants to recharge these EV batteries. Only difference being, instead of burning a Diesel/Petrol/CNG/LNG in an IC engine's cylinder now, the gas needs to be fired in the boiler of a thermal power plant later, of course to a lesser extent because of the capacity and efficiency advantage.
But did anyone try to measure how much the fuel savings could be if we fire fossil fuel in power plant boiler than in an ICE cylinder? It will be definitely less. But how less is really less? So as to say that the demand for fossil fuels, be it Coal/LNG/CNG, will fall dramatically?
If equitymaster comes up with some analysis on this front, it will be really interesting to know.
I really appreciate your effort in this direction.God speed Good luck.
Apart from EVs, a lot of work is being done on hydrogen cell vehicles - which uses hydrogen instead of hydrocarbons; the tail emissions will be water which is not a pollutant. As such, I understand that work is done for using water as fuel that is converted as hydrogen and oxygen through chemical reaction; hydrogen part is used as fuel. A patent is pending in Japan for this process. When these projects will materialize for commercial use is anybody's guess. But they will in course of time.
