The rise of batteries in six charts

It is a little bit for a bunch of reasons, but how does improving battery storage change the generation mix?

State policy is fundamental to the entire green revolution. None of it would have been possible without nations incentivizing it. Eventually once the entire energy generation/consumption cycle is entrenched and we are all dependent on it, they can safely take away the incentives.

It's a bit like changing the tires on a moving bus. Somebody had to pay for the new tires and wheels, and the support truck to run along side the bus, and the extra fuel, and a discount for the new tires, etc. Once the new tires are on the bus can keep driving without support.

This is a great set of charts and analysis, although I have two problems with it.

1. On the chart of energy density, I'd like to see the the energy density of petrol for comparison. It's much higher, and even though extrapolation is dangerous, I'd like to see how long it could take to reach parity given some of the different forecasting models they mention. Specifically regarding their mention of air travel, I'd like to know what the minimum viable energy density would be for a vessel's fuel source, because my current understanding is that commercial air travel powered by electricity is not feasible.

2. They mention S-curve adoption, but that reaches a horizontal asymptote eventually, it doesn't go up forever. I'd like to see more analysis on where we think we're at on the S-curve, and why. I'd like to see a guess on where it levels out displayed on that chart, instead of the arrow simply pointing at the sky. If nothing else, show where the chemical limit might be based on current battery technology.

I want to displace fossil fuels and reduce pollution and slow the greenhouse effect as much as possible. I think transparency and realistic expectations need to be part of the transition. The more information available to markets, the more efficiently they can work towards the goal. I find it very difficult to get answers to these types of questions when discussing renewable energy generation and storage. I'm sure part of it is my own ignorance on where to look, which is why I ask: especially here, hopefully an expert can see this and quickly point me in the right direction.

Batteries can also help to handle peak demand.

Yes, it was by far the most encouraging thing I read in a while, thanks for posting!
