7 quotable lessons, heuristics and mental models. Every one is playable at the moment it was said. No fortune cookies allowed.
“what we find in the modeling is that there's a lot of value for sort of up to 10 or 12 hours, let's say. Um, there is less value. I'm not going to put a specific number, but there's, there is less value that we see very markedly in the system, um, until you get back up to about 75 coming in on a hundred hours. And…”
“By having cost-effective multi-day storage, you can incorporate More renewable energy without sacrificing reliability at basically half, half the land cost, and that, by that I mean you only have to put solar on half as many acres to get the same benefit, um, and that's because you're essentially solving the…”
“In the case of lithium ion, Let's say that's roughly a hundred dollars a kilowatt hour. You're adding a hundred dollars for every hour you want to discharge. And, and, and the industry normalizes around dollar per kilowatt in terms of comparative resources. So, uh, everything comes, comes back to that figure in the…”
“having a hundred hour duration resource is a physical hedge against price spikes in a way that you can only really financially hedge right now, um, unless you have, again, thermal resources. So it, it sort of opens up a new, uh, A new frontier for market participation in a way that short duration storage does not.”
“the reason why that number of hours, you know, four days roughly, uh, becomes relevant is because that's where a lot of the material weather events sort of sit in terms of duration.”
“having storage, you know, the ability to buffer at one end or both ends, uh, makes that, uh, even more a highly utilized resource.”
“the ability to have a type of resource that allows you to, what we call, shape around that risk. In other words, move your energy by, you know, by days, essentially, um, is what's required to get out of that Conundrum that, that a lot of existing plants find themselves in today.”
