I understand that there might not be suitable batteries that could charge up as fast as a lightning strike. But has no advancement been made in that field yet ?
For its tapping of having Mega Volt level, right now we do not insulation beyond 1500 KV or so.
High voltage and high power density makes it unfavorable for tapping
Dear Jitin,
It has been proposed that the energy contained in lightning be used to generate hydrogen from water, to harness the energy from rapid heating of water due tolightning, or to use a group of lightning arresters to harness a strike, either directly or by converting it to heat or mechanical energy. Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.
“If all its energy could be captured, an average lightning bolt would provide about 5 billion joules, equivalent to 0.85 barrels of oil. But there are problems for storage or tapping. Kerosene, a non-renewable source of energy is becoming costlier and is going out .Solar lighting is providing an environment/ health friendly and cost effective lighting. In all the projects though a possibility of subsidy availability from the ... There is a vast untapped potential in rural India for these projects irrespective oof all.
Taping is difficult due to cost and potential storage medium.
Hope it is helpful for you.

B Koti Reddy , Is there some way how we can drain Excess charge to Earth and use only that which we need ?
As on date there is no such provision. It is mainly voltage which can not be controlled
Hope, these post would help you.

my mad scientist idea. Is to have a metal screen or some kind of collector on a mountain that reaches into the clouds and collects the static charge in a capacitor before the lightning reaches a high enough voltage to strike. It is possible but would be unreliable and dependent on a storm passing right over it. Really simple. You have one lead of a capacitor attached to the collector and the other lead grounded in the earth.
After reading the articles RS Krishna listed above. Think of it this way. All storms area caused by the sun causing evaporation. Lighting is caused by gravity separating (simply put) heavy cold protons that fall in the cloud from hotter electrons that rise in the cloud. All that energy in the lighting strike came from the sun. So solar is a better option and closer to the original source.
lightning strikes are usually associated with TRANSIENT OVER VOLTAGES DIFFICULT to manage in time and value
