I dislike co-optimizing capacity investment and operational dispatch. Rules based with limited foresight is more realistic and computational tractable. Let's get these models running in real time folks

This week on @cleaninguppod.bsky.social, @worthingtonbry.bsky.social spoke with Kate Brandt, Google's Chief Sustainability Officer. Google has promised net zero in 2030, but their emissions are soaring. Bryony asks the right questions - does Brandt give convincing answers? youtu.be/Es6xJvfYs_8?...

24/7 clean procurement catalyses learning for long-duration energy storage and clean dispatchable power - new op-ed in @latitudemedia.bsky.social! 🔌💡 www.latitudemedia.com/news/how-24-...

www.latitudemedia.com/news/how-24-... If you aim for the finish line with hourly/regional constraints, the need for innovative energy technologies is quite clear. This kind of procurement can support the tools required to get low carbon, energy abundant grids. Let's finish the drill.

You take the annual pill, the story ends. You wake up in your bed and believe the LCOE is the end of the story. You take the hourly pill, you stay in Wonderland, and I show you how deep the rabbit hole goes (anti-correlated 20 yr weather profiles and varying storage capacity values).

Also, AI training is not exactly "base load" due to all-reduce operation training. Minute basis oscillations in power are just arbitrage opportunities waiting to be realized! (this is part of why xAI has a megapack on site, to smooth out these oscillations)

We really need something like a FERC but with a mandate across *all* real-time energy flows...

DAMMIT NPR. I spent nine months upgrading over TEN THOUSAND desktops at a F500 client. The grand total was over SEVENTY THOUSAND applications upgraded. Y2K "didn't live up to the hype" because the industry busted ass to duct tape everything first.

This is what I call the "Default Plan". Build W+S and if cheap enough, some storage in a NG based firm capacity system until "cannibalization" means there isn't enough revenue to build more or system costs rise. It looks to be a very sticky local minima.

If we are satisfied with a 100-200g/kWh electrical system the 'default plan' gives us nice cheap power, and we can carry on. But to get below 50g/kWh, a system with a lot of nuclear becomes much more palatable. And to get rid of NG for the power sector entirely, it's much nicer.

I was at an Austrian Christmas market and I swear I heard AI slop and flagged it, I’ve played with it enough to be able to sniff it out.

Hey friends, did you miss me in the last few years? How do I get plugged into the old #energytwitter? Am I allowed to just reproduce some of my old popular threads from twitter?

How many ppl really know how electricity markets work. I still feel like it’s facing the abyss every time I try to wrap my brain around the short run dispatch/ long run capacity game and all the different markets and abstractions.

Cool, we’ve been adding on average 260,000 nuclear bombs worth of energy per day in the biosphere for the past 60 years. No chance it could do any damage tho, just a little heat right?

Interesting! Holding onto some tail risk in my mental model here that a cascade ends up screwing us

PJM's Board letter is a must-read for those interested in clean energy policy. The specific roadmap is important, but more relevant is the PJM's assertion that there is simply not enough clean energy to maintain reliability without new (likely gas) generation. 🔌💡 www.pjm.com/-/media/DotC...

The annual BloombergNEF battery survey is out. Quick hits: pack prices now $115 per kWh (and below $100 for cars in China) Almost 2/3 of China's EV models are priced lower than their internal combustion equivalents Great work @colinmckerracher.bsky.social www.bloomberg.com/news/newslet...

We are so back

The @arnabdatta.bsky.social article definitely got some attention, worth also noting he is one of the most creative policy entrepreneurs out there on how to actually achieve the high level goals. The one place I do think the conversation needs to go is how to reengage the people. /1

The “fossil fuels are hard to beat” (complementary) and “fossil fuels are hard to beat” (derogatory) battles have begun again, we’re so back.

"It’s more appropriate to think of the lithium-ion battery not as a single invention, but as a steady accumulation of many inventions that were needed to both make a battery practical and to unlock its full potential." This is true of all innovation. www.construction-physics.com/p/how-we-got...

Worth considering. The fact that API and the vehicle industry and the utility industry and the labor unions are not united in opposition to kill ambitious climate provisions is unique, vs the Kyoto and Waxman eras.

I agree with @arnabdatta.bsky.social. This is not 2016. We cannot just abandon federal efforts and “pivot to states”—it’s both/&.

Key point is that China has been investing in EVs for over a decade to reduce its dependence on imported oil. No country wants to be dependent on imports for key energy or security needs. And that's a big reason why it is unlikely that projections of high LNG demand growth in Asia will be realized.

Excellent reporting on China's affordable EVs that are as robust as US made cars. No amount of $7500 rebates or ridiculous tariffs will match the hubris of Detroit automakers whose only solution to competition is protectionism. If they can't compete in a global market, they should get out.
