You know that fossil fuel & food majors work their way into UN COP climate negotiations.

You know they secretly push their corporate agendas.

Would you like to see how?

This new paper uses ML to uncover what happened at 20 years of COP side events:

How ‘long’ should long-duration energy storage be, and how soon will we need it?

This graph shows we can get quite far along the energy transition with the storage techs we are deploying today! But by the 2030s, multi-day storage will be needed to reach higher renewable shares. The graph shows much renewable energy can be used as its share increases. As you start going beyond 50% VRE share, the time mismatch between supply and demand means that without flexibility, some will get wasted (curtailed).

Are you losing sleep over which energy storage technology is best for which application? 😴

Let me introduce "competitive landscape" charts, show you what insights they offer, and give you the tools to make your own!
👇🧵 These ‘competitive landscape’ charts show the technologies with the lowest lifetime cost across all discharge durations and cycling rates. They cover second-by-second balancing (in the bottom right) up to inter-seasonal storage (top left), and everything in between.

I was utterly floored by an email yesterday. A 12 year old boy wrote to ask "what can my generation do to convince the politicians to act on climate change and get our country off fossil fuels?"

I'm looking for advice from Twitter to give him the response he deserves... [1/5] My thoughts so far (with the help of friends) are:

(1) The fact you're asking these questions and care about them is the most important thing.

(2) Nurture your curiosity and passion. Read up, go to talks, study hard so you have the skills you need to change the future. [2/5]
