Good question !
Yes, Lithium Ion batteries are there since last 30 years. Still it was never popular in Automotive application for obvious reasons - if you read through the posts above ( I would strongly recommend you to go through the Green hydrogen thread …if you have not …)
But today for the last 2 years , it is becoming popular because there is no other choice right now.
(1) EV technology was known for the last 50 years, but still EV was not popular…not produced commercially in large numbers…it is only during last 2-3 years that we talk about EV ! Why and how ?
(2) Similarly, Hydrogen as fuel cell and ICEV
technology was known since last 50-60 years…but it is last 2-3 years that we are trying to commercialize Hydrogen fuel vehicles. …
(3) Similarly, Solar/ wind power was introduced in India in 1985-90…but it never became a success. . I lost money in a wind turbine company called NEPC Micon in 1990. …I am still holding the stocks …the company no longer exists…same story with Suzlon…
But how is that today , a lot of companies making a lot of money in Solar and wind power ? Why and how ?
(4) same story with ethanol…it was known since last 30 years that 15-20% ethanol can always be mixed with petrol without any major changes in engines…but it was never done, thinking that it is not possible. today we are doing it …Why and how ??
(5) Grey hydrogen was a well known and established technology concept - Hydrogen produced from Methane , other hydrocarbons , coal…but today we are discouraging this …the whole world now Wants Green Hydrogen everywhere! No more Grey Hydrogen ! Why and how ?
(6) Nobody thought IT companies can double our money within a year ( I am talking about large cap ) …small IT companies have given 300-400% return…and all analysts say it is a multi year Growth story in IT? Why ?
(7) Semiconductor disruption has happened…there seems to be no end to the issue ! Why ? Now only a lot of companies are coming out with a lot of plan…but damage has already happened and we are yet to come out of this issue!
(8) Covid 19 type disruption never happened during last 30 years … but today it has happened
So what all we are trying to tell that nothing is impossible and anything and everything is possible .
Technology has not invented men…it is the men who invented technology !
Technology is evolving ! Necessity is the mother of invention ! Men can go to any extent of discovering technology which is sustainable …
