Stadler: Pure solar and battery microgrids are uneconomic for outage resilience
“If you, if you're focusing on costs and carbon emissions, you will always see a combination between renewable technologies and In some gas fart engines for backup reasons or for resiliency reasons, right? It's pretty bad idea from an economic perspective to ha…”
Khan: Industrial AI startups must train on customer data to scale
“If the training data is all private and walled, you got to be able to use your customer's data to train. They're not going to like that, and you got to figure out how to get over that hump, and if you can't get over that hump, there's kind of no way you end up…”
Chiang: Electrochemistry's major limit is being a two-dimensional interface process
“The limitation of electrochemistry is that it's a chemical reaction that takes place at an interface, right? In a way, you could say that it's a two-dimensional process, right? You know, you always need an electrode, and you need electrons being transferred ou…”
Koomey: Software moves on one-year cycles while physical infrastructure takes decades
“The world of
Bits moves really fast. They have all the money in the world. The world of atoms is slower. So it's like a year for the world of bits, 10 years or 20 years for the world of atoms, and so it's like a mismatch.”
Datar: Biopharma lacks incentives to lower costs, but cell ag must
“Biopharma has set this precedent that this is what the price of things should be, and they have no incentive to bring the prices down. Cellular agriculture does have an incentive to bring the price down, and it must bring the price down.”
Datar: Cultivated meat factories should resemble food processing, not biopharma
“But I also think if we're willing to have that same disruptive paradigm shifting mentality, that maybe the manufacturer of this looks more like vitamin or food processing or those kind of other still factories, still produce stuff that you consume, but isn't t…”
Fernandez: Climate tech scaling requires sequential 5-20x demonstration and FOAK steps
“The way we propose to do this is, you know, that company has to follow a path towards that de-risking, and that path in our, ah, experience is you go from a pilot to a five to 20 x demonstration project, and then you go to another 10, 10, 20 times, ah, first o…”
Fernandez: FOAK Project Investors Require at Least Six Months of Demo Data
“What we know is at the end of the day, the investors that come in at the Series C, Series D, you know, most of the time funding or partially funding first of a kind projects, they really want to see six months or more, or performance because things degrade if …”
Fernandez: Startups lock in offtake prices before engineering reveals 2x CapEx
“We find that many times off-takes are priced in a way before engineering, you know, failed one, failed two, engineering have been done, and it's based on optimistic CapEx assumptions. Now, when the companies go through the engineering process and they actually…”
Kann: There is no construction financing market for FOAK climate projects
“There's no, construction finance is a thing if you're building a utility-scale solar project, but if you're building a first-of-a-kind thing, there's also not really, we've been talking about, like, financing the long-term operation, there's also not really a …”
Scheyder: DLE is not universal; each brine requires tailored technology
“DLE is not a magic bullet. Just because somebody cracks the code somewhere does not necessarily mean that it's going to work elsewhere, because each brine is different.”
Janous: Securing electric power creates a defensible competitive moat in AI.
“And so not to mention the fact that the ability to acquire and collect those electrons then in some ways creates a moat against other folks that would want to try to do the same thing. So the more electrons That you can get a hold of, especially in the AI worl…”
Janous: AI companies pay huge speed premiums because base infrastructure is cheap.
“The cost of the base infrastructure for my end product is actually really low. And when I say base infrastructure, I talk about land, you know, power a data center shell, you know, those things are relatively inexpensive. In the grand scheme of operating, you …”
Janous: Continuous data center loads benefit grids by improving infrastructure cost recovery.
“Having more data centers on the grid is good because they use power 8007 60 hours a year. So there's more cost recovery for more infrastructure in more hours if you have more data centers.”
McGavis: Refrigerant venting happens because contractor labor costs exceed reclamation value
“Today, the primary Driver for a lot of the venting is economic. It, the technician or the contractor's time is worth worth more than actually collecting the refrigerant and selling it into the reclamation market.”
Thiel: Synthetic fuels require $1/kg hydrogen and $100–$200/ton CO2
“And you know that, you know, for a fuel, if you want to get anywhere close to economically competitive, you know, subsidies decide you have to have hydrogen that's going to be on the order of a dollar per kilogram, and you have to have CO two that's in that 10…”
Sublime CEO: Standards are not enough; concrete workers reject stiff mixes
“These performance-based standards, the ASTM, the ACI, all of these things are necessary, but not sufficient in the eyes of the concrete subcontractor, because they have to make sure it finishes in a way where it doesn't hurt that man's elbow, because if you ge…”
Johnson: Uniform national power pricing incentivizes building generation far from demand
“So a lot of countries around the world have the same price nationally, no matter where you are, which means people are incentivized then to locate in the place where they can get land or they can get a grid connection, which isn't necessarily the place where y…”
Çubuk: Deep learning scaling laws apply to quantum mechanics and materials
“The more training data you put into LLMs, the better results you get, and how much better your results are actually predictable. It's kind of like a power law. This comes back from, you know, a paper from Baidu Research from back in 2016, I think, and it seems…”
Lubershane: Capitalizing alternative tech in mature climate areas paralyzes deployment
“There are some areas, though, where I do think that the mousetraps we have are good enough, and actually are likely to get better incrementally on their own, such that funneling a lot of capital into trying to build a differently better mousetrap is probably a…”
Lubershane: Energy storage startups underestimated lithium-ion cost declines from manufacturing scale
“I've, you know, watched and talked to dozens of companies and founders, and I think Oftentimes making the same mistake as they were trying to commercialize some kind of better mousetrap for energy storage, which is they underestimated the pace at which the cos…”
Johnson: Commercial hydrogen discoveries require 10k-50k tons annually over decades
“If you want to produce liquid hydrogen, you got to be producing 10,000 tons per year, give or take. If you want to be, you know, producing ammonia, you know, you're probably in the neighborhood of like, 50,000 tons per year is a good amount of hydrogen. So I w…”
Briscoe: Obligated EPA green bank funds will be legally harder to claw back
“I do believe once it's once it's obligated, once we get through all of the All of the T's and C's with EPA. It becomes much more legally and politically much more difficult to plow back capital that's already been obligated and deployed, or at least beginning …”
Berdichevsky: Volumetric energy density is the most critical metric for EVs
“The most, so my view, the most important metric for EVs is energy density, defined as watt-hours per liter, volumetric energy density.”
Belady: AI power demand is purely additive, unlike cloud efficiency migrations
“So now what you see is AI coming along and that's like a completely new application and it's a massive application. So now that's just stacking on top of this other transition of, as things move from enterprise Into the cloud. And now your stack on top of that…”
Belady: Speed of light latency forces AI into massive, centralized data centers
“I think, and again, this is probably beyond my scope, but I think it really has to do with the size of the models and the latency, right? It takes too much time for light to travel larger distances, as hard as that is to believe. And so they tend to concentrat…”
Horne: Low rock conductivity fundamentally limits closed-loop geothermal heat extraction
“In the case of a drilled hole, the surface area of the hole is quite small, and therefore you depend a lot on conduction of energy, thermal energy through the rock. And rocks actually are not very good thermal conductors. Rocks are kind of insulators actually,…”
Janus: AI technology is advancing faster than electric utilities can build power
“The problem we were going to have was going to be whether we would have enough power to support this technology that was moving at a pace that, as you know, moves way faster than the electric utility industry.”
Janus: AI training latency constraints require single-site gigawatt data centers
“Because those training models are in and of themselves a big machine, and so you can't, and this is not my forte and my area of expertise around the actual architecture inside of a training model, but my understanding of sort of the constraints there is that y…”
Baglino: Overbuilding renewables for winter enables cheap, flexible electrification
“With the current known technology costs for different types of storage and different types of generation, what the model does is it really Largely overbuilds renewables to solve the winter scenario, right? And now you have this large overbuilt renewable base. …”
Baglino: Memory and Chip Interfaces Are Biggest Bottleneck in AI Hardware
“One of the biggest bottlenecks for everything that's going on with AI is actually the interfaces, the memory interfaces, the data interfaces from chip to chip, all those things. And those have not seen as much innovation, actually.”
Faruqi: Time-of-use rates are a poor fit for heat pumps
“A heat pump, which is both an air conditioner in the summer and a heat source in the winter, will be running precisely when there is a peak situation in the summer or a peak situation in the winter. Actually, it will create a peak demand in the winter that cur…”
Faruqi: Utilities do not need pilots given 400 existing global trials
“Let's try to actually move to actual implementation, and my advice is you don't really need to do a pilot because we already have 400 pilots across the globe.”
Shah: Electric utilities value dispatchable home batteries over rooftop solar generation
“I think we're just at a point now where people recognize that what's really of value to the electric utility company is dispatchability. Right? It's not the generation of power on rooftops. It's the battery that's actually in the home.”
Steingart: Battery recycling is a tolling operation without supply ownership
“I think the brutal truth is, is that it's a cost center, and that inputs, recycled inputs, are ultimately a tolling operation unless Redwood can pull off owning the supply. Because if Redwood can pull off owning the supply, then it owns the mine of the future,…”
Steingart: Mining Giants Lack Economic Incentive to Scale Battery Recycling
“So, in terms of their unit economics, it doesn't make any sense For a mining company to involve itself in recycling in a big way in twenty-twenty-four, both because all of the recycling material coming in, or most of it is, is scrap, and, ah, what's not scrap …”
Steingart: Battery Recycling Margin Gains Will Be Quickly Eroded by Price Competition
“So, so, in a perfectly efficient market, recycling is just a tolling operation, where it is, will exist to an extent that it can keep its costs neutral, and every time there's an advance that lowers the cost of recycling, there will be a year or two where that…”
Groarke: Modeling grid physics is the primary barrier to full automation
“The primary reason why, you know, we're not on a path Towards, you know, full automation, and there's, you know, been a spade of use cases launched is just modeling grid physics accurately is incredibly difficult, right, for an algorithm. So, you know, solutio…”
Stacey Kauk says early-stage carbon removal startups take three years to deliver
“That's what we're seeing play out is, you know, it is about three years before you can get those deliveries, because when we're making those purchase decisions, often we don't have full visibility, and neither does the company.”
Bullard: Obfuscating ESG data backfires by giving analysts more interpretive discretion
“It's also, I think, in the long run, maybe a pyrrhic victory to sort of obfuscate your data by not putting it into a table, because for one thing, people will get it, and they may be less sympathetic to your position if they had to, Do a lot of extra work to g…”
Bullard: Markets are created by removing legacy subsidies, not just adding new ones
“You know, we think about markets being willed into being by a new subsidy coming into place, or a new support mechanism, but they're also willed into being by other mechanisms going away.”
Cabiyo: Assuming harvested biomass power has zero net climate impact is flawed
“All these facilities are predicated on carbon neutrality that if you harvest biomass and burn it, you have no net climate impact which is probably a simplification that we should stop making. Oftentimes you can get close to that, but it's not always going to b…”
Cabiyo: Removing crop straw depletes soil carbon, impacting BECCS accounting
“If you are leaving straw residue on a field and letting it decompose, it actually, a lot of that carbon ends up stored in the soil, up to a certain threshold. So if you start taking it off, you can actually get decreasing soil carbon and that's usually not ref…”
Cabiyo: Biomass CDR accounting must be measured at regional ecosystem scales
“What we came to in this report is that you should be looking at sort of a regional, like, ecosystem-defined scale, where you have you know, maybe it's the size of, like, a small U.S. State, where you have a kind of ecologically continuous forest and you have, …”
Orbuch: Next-generation carbon registries must be buyer-funded with ex-post credit issuance
“So there's two things that change. One is that the buyer pays the registry to evaluate deliveries and two, the credits are issued after they've been delivered, not preemptively before.”
Orbuch: Overly conservative scientific governance breaks carbon removal project finance
“Like, loudest, most conservative scientist in the room-based governance doesn't work for this. You actually do need to make something off-takeable and contractable, and the way you do that is for these emerging more uncertain approaches, or the approaches that…”
Yeh: FOAK investors must be long-term greedy for nth-of-a-kind returns
“In order to do first of its kind, to be an investor that's an anchor or a catalytic investor, you have to be long-term greedy.
And I think that's understanding that the first of its kind project you're doing is not the only project you're doing.
You're doing…”
