Caelon Caelon:
The limited supply of lithium means going all electric will generate shortages and escalating prices. We can have a bigger impact by using the limited supply of lithium to produce more hybrids to reduce fossil fuel consumption.
Lithium is but one metal that can be used in rechargeable batteries, and it isn't even the best one.
There is a lot of development on storage, and even Tesla is moving to a Lithium Iron Phosphate construction, and NASA has been using a Sulphur Selenium chemistry for decades. There are chemical batteries, and kinetic batteries, and gravity batteries . . . and as you say, hydrogen.
Saying we shouldn't do something because of current technology precludes the cleverness that we humans have shown over thousands of years. We will find alternative storage methods, even if we have to use compressed air and water towers to store solar energy.
There are so many videos in the last months that I haven't posted here, but believe me when I say lithium availability is the smallest problem the climate is facing right now. We have to do a little of everything we know in order to make the changes that are needed quickly.
