Batteries are a vital part of the energy transition. Here's why: - They're the fastest growing clean technology on the market - They help meet climate goals & ensure energy security - They bring down emissions in power & transport International Energy Agency's new report ➡️ iea.li/3QmAogL

The reason batteries are now seen as the solution is their spectacular price reduction. When I wrote a book on electric vehicles in 2008, prices where around $1500/kWh and they didn't last long. Now we are heading for $50/kWh: 30x less! See my thread: x.com/AukeHoekstra/s…

In 2019, the average size of battery storage projects built in the U.S. was 4 MW. The average battery built so far this year was 61 MW—15x bigger.

5. Lithium-iron-phosphate is taking over the battery market. It is set to cross 50% of the passenger EV market in the next 2 years, dramatically reducing the need for nickel, manganese and cobalt in the years ahead.

Really important stuff ⤵️. The clean energy transition is largely about substituting fixed capital assets for fuel consumption. That makes the cost of financing clean energy projects extremely important to the overall cost of the transition. Developing countries face higher

Päästöt ovat laskeneet vuonna 2023. Pikaennakkotiedon mukaan päästöt ilman maankäyttösektoria laskivat 5,1 Mt eli n. 11 % vuonna 2023 verrattuna vuoteen 2022. 📉 Maankäyttösektorin nettonielun heikkenemisen johdosta nettopäästöjen kehitys on kuitenkin huolestuttava.

Exploding CfD cost only arise if electricity demand grows much slower than supply (or if CfDs are badly designed). We suggest to improve cross-border coordination of electricity system development & enhance visibility of electrification-trends ...

We no longer need to model for when cell prices drop far enough to decarbonize road transport. That day is here trib.al/lLZOvrL

# RLHF is just barely RL Reinforcement Learning from Human Feedback (RLHF) is the third (and last) major stage of training an LLM, after pretraining and supervised finetuning (SFT). My rant on RLHF is that it is just barely RL, in a way that I think is not too widely

Not sure there's a single chart that better summarizes the relentless improvement of batteries. Costs down over 90%, energy density up ~5X. In just over 20 years. Innovation is incredible. Chart from RMI rmi.org/the-rise-of-ba…

This is a great illustration of the impact batteries are having on electricity markets. 1. Batteries are taking over ancillary services markets. (services that ensure reliability and maintain things like voltage and frequency) 2. Because batteries can provide these services at

Fully electric drivetrains are winning the race so far in the heavy truck segment, with fuel cell vehicles capturing only a small share of the market.
