Modon: EPCs reject better software because efficiency cuts billable hours
“There's no real incentive structure for an EPC to want better software. It's the same reason your law firm doesn't necessarily want like AI software to help them accelerate, you know, and reduce their billables.”
Garabedian: Deploying hundreds of small containerized electrolyzers is highly cost-inefficient
“The idea of integrating onto a site hundreds and hundreds of very small containerized electrolyzers, it turns out to be quite expensive. And in no small part, it's expensive because it's very hard to drive the cost out of those units, but also because the foot…”
Grunwald: Less Intensive Farming Requires More Land and Harms Biodiversity
“First of all, to the extent that regenerative or organic or basically more natural Kinder and gentler forms of agriculture make less food per acre. They're gonna need more acres to make food. You know, land agriculture that is less intensive needs to be more e…”
Orbuch: Legacy carbon offset market operated as an aligned house of cards
“Because the registries and the feedback loop with the registries is to just keep issuing credits and make each credit look the same as every other credit, everyone's incentivized the other way because the buyers don't want to go back and say, Wow, all this mon…”
Hertz-Shargel: Siting Bitcoin mines beside existing renewables merely displaces clean power
“The reality is that The total number, the total amount of load on the system has grown, and therefore all you've done is displaced other customers who would be served by that renewable generation. So it's, and so your number of pigeons has grown, and so you kn…”
Kugelmass: Poor construction methods and subsidies crippled global nuclear deployment
“The only reason that we don't have 10 times as much nuclear As we do today, both installed, but also being built, is simply because the way that we have decided to build them is terrible. Just overly complex construction, like, awful financial incentives, usua…”
Bataille: Enhanced oil recovery is the first major use for captured CO2
“The first biggest use if you're going to do CCU is actually enhanced oil recovery in place of other higher emitting oil sources as we climb down from a hundred million barrels a day down to zero sometime mid-century. But, you know, obviously that's a contentio…”
Lubershain: Data center demand shock creates systemic price inflation across electricity delivery
“There's a demand shock and supply chains, like basically every step in the supply chain for equipment, For the electricity system to deploying that equipment and getting it online and hooking everything up is bottlenecked and cannot keep up with demand. And be…”
Lubershain: Special local tariffs cannot prevent data centers from raising systemic power costs
“We're adding a bunch new costs to the system at a global level that there's very little that, basically nothing that your friendly local utility or data center developer can do about, no matter what kind of, you know, special tariff or agreement they negotiate…”
Tillis: Lawmakers ignorant of power purchase agreements are unqualified to direct energy policy
“If you're taking a definitive stand on power policy, and you don't understand something as basic as the power purchase agreements that drive it, then you're not qualified to have that discussion, respectfully.”
Hade: Storage aids grid operators but underdelivers financially for investors
“Grid operators are benefiting from storage assets. That's just definitively true in all markets where storage has been deployed at scale, right? This stuff is working and it's helping to solve a lot of the problems that we have on the grid. And at the same tim…”
Chinese automakers will target high-margin US trucks and SUVs, not cheap EVs
“The Chinese are starved for profits, and when I talk to the Chinese manufacturers, they're far less interested in solving America's affordability program and far more interested in saying, how can we attack the larger SUV and pickup truck segments?”
Vahdat: AI inference does not require gigawatt-scale data center capacity
“You don't strictly need a gigawatt of capacity to be able to do useful work. You probably don't even need a hundred megawatts of capacity. It gets a little bit more interesting than that because of, let's say, co-located compute and storage and networking and …”
Vahdat: The AI industry should accept lower-reliability power delivery
“No, it is not intrinsic and we should be thinking about lower reliability power delivery overall.”
Vahdat: AI scaling bottlenecks constantly rotate between labor, power, and chips
“When delivering the end-to-end, we unfortunately don't have the luxury of focusing on a single limiter. I would say very sincerely and honestly at 10 a.m. It's labor, at noon it's power, and at two p.m. It's chips every single day.”
Bayes: Renewables hedge geopolitical disruption while fossil fuels hedge grid reliability
“Fossil fuels or conventional fuels are a hedge on reliability, ultimately, that they provide reliability benefits to a system that has become more reliant on, ah, intermittent sources of electricity, but clean energy systems or renewables are a hedge on geopol…”
Microreactors make zero economic sense without scaled factory manufacturing
“Microreactors in particular do not make sense economically until you're building them in a factory with a plan for shipping those reactors fueled and receiving those reactors, defueling them, those sorts of things.”
McGinnis: Permissionless plug-in systems can eliminate residential install soft costs
“Permissionless can effectively Put that to zero. Because two of the big components there are three of the big components are permitting labor and CAC. And so think about a buy online motion where a consumer is just going to Amazon and buying one of these and p…”
Rountree: Selling low-cost commodities offsets deep tech technical risk
“Why I love commodities is because
It offsets the technical risk we're taking with less market risk, because I know if I'm selling a commodity, i.e., my product is molecularly identical to the competitors, but I have a cost advantage, I know you can sell that.”
Matthew: Hyperscalers hype power constraints to induce third-party infrastructure overbuilding
“So if you think about that from a power standpoint, my incentive in that scenario would be to talk up power constraints, right? Saying that there's not nearly enough of it. We need to build so much. Like this is the greatest cycle because that will incent spec…”
Chubuk: AI cannot reason to breakthrough superconductors from training data alone
“I think it's still true that it would be difficult to just reason your way into a much better superconductor. I actually would guess that there's a law out there that we haven't discovered yet that says that you can't just look at your training set that's diff…”
Chubuk: LLMs already bridge solid-state chemistry and physics better than human specialists
“Like, there was probably a time when a physicist could contribute and be one of the best in the world on many fields of physics, but it's definitely not true today, and this is one of the reasons I think we are very excited about LLMs, because when you talk to…”
Guernsey: Lack of smart meter data access throttles residential demand response
“When I think about the growth of our residential portfolio and what's, I think you used the term rate limiting there it's the lack of access to, and I'm going to air quotes here for the listeners, smart meters, right? So we deployed all these smart meters, we …”
Reinhardt: Fixed pyrolysis facilities break unit economics compared to mobile units
“When you start moving away from a mobile piece of equipment into a fixed facility, You do get some economies of the construction, but you actually take on a lot more risk in every facility that you build. You have all the balance of plant, you have permitting,…”
Reinhardt: Biomass is best utilized for carbon content, not energy
“What's interesting about it is that relative to almost everything else, it's very carbon rich. And so the use cases that rely either on the chemical availability of carbon or on, ah, the sort of physical availability of carbon, those, or like in the case of ca…”
Reinhardt: Removing carbon is cheaper than $2,000/ton building decarbonization retrofits
“It's gonna cost, like, 2000 dollars a ton for me to go, like, tear down a building and rebuild it with, like, a proper HVAC system that does, like, heat pumps, you know, it's like, and have clean concrete, like, you know, at some point you get down to this, li…”
Kann: Geoengineering is too cheap to support large venture market sizes
“It's actually hard to get to a big market size for it, ultimately, because it is so cheap. Like, I don't remember exactly the number, but we did an episode on this, like, I don't know, a couple years ago, and it was something like a couple billion dollars migh…”
Kann: Being green and more expensive is insufficient for climate tech demand
“The big lesson of the current state of affairs in climate tech is that in a lot of the subcategories of the market,
Being clean, being green, whatever, is insufficient.
Being ex but clean particularly if it's ex but clean and more expensive.
Is just not eno…”
Second-life EV batteries require just one to two years to become profitable
“The life of the second life battery on the grid is, it's certainly long enough to be economically valuable, and that, in order to make economic sense, it's really one or two years, hundreds of cycles, low hundreds of cycles.”
Second-life EV batteries excel in four-to-twenty-hour long-duration grid storage
“We can certainly play in the two hour, four hour markets with repurposed EV packs, second life packs. Where we see them really starting to shine, though, is in the longer duration. Markets. So four hour, eight hour, maybe longer, maybe 20 hour. And that's beca…”
Kelty: Tariffs to force domestic battery production increase EV prices and stifle demand
“Like, if you want, if you're really trying to encourage domestic production, ah, in the US, you would put in tariffs to increase the cost overseas, and you'd, you'd incentivize local production. The problem with that is that your cost would end up going up hig…”
Stark: Chasing industrial waste heat is a waste of time
“Waste heat is a waste of time. It's actually limited this industry for some time, because people are chasing after a small increase in COP to be able to justify and minimize OPEX, but what they've inadvertently done is, It's essentially driven a massive increa…”
Sharp: Advanced reasoning models force AI infrastructure into tier-one hubs
“As you see bimodal, some of these more advanced reasoning models where a token isn't just generated against a prompt, and then you consume it, and it's done. A token may be generated inside of an AI world and go through multiple models to ensure that, you know…”
Permitting new transmission lines is globally harder than building nuclear plants
“It's going to be easier to permit and get a nuclear plant built than it is to get new transmission lines, and that's just historically how it's been, you know, everywhere I've been, whether it's in the US, the UK, Australia. Over in Taiwan Philippines, people …”
Brown: Individual AI adoption equals hundreds of millions of new HVACs
“Like if you think about the idea that maybe as each individual having kind of an AI co-pilot, that's the equivalent of like having hundreds of millions of new HVAC systems all of a sudden being put onto the grid.”
Schroepfer: Customers buy savings, making 'climate tech' a confusing category label
“I would actually say it even slightly stronger, which is we use this word climate tech like it's an actual good definition of a market segment. When we just talked about like, I sell products to consumers that save the money. I'll sell products to consumers th…”
Schroepfer: AI does not solve climate tech's manufacturing scale-up bottleneck
“AI for material science, great for discovering new materials. The manufacturing scale-up is usually the hard part. So great, I've got this new MOF. I've got to make a lot of it very cheaply. The AI doesn't really help me very much with that. Like, in theory, m…”
Koomey: Rebound effects from efficiency gains are typically only 10 to 20%
“Yes, the car's a little bit cheaper, and yes, people drive a little bit more, but generally, these effects tend to be kind of small. They tend to be kind of 10 to 20%.”
Datar: Cultivated meat startups shouldn't attempt full vertical integration early on
“If we actually think about a world where food is grown from cells, we need a really robust, diverse kind of economy behind it with many different players and so on. We can't just come out of the gate vertically integrated like the meat industry today.”
Datar: Venture capital is improperly subsidizing basic research in emerging tech
“It's a lot easier to be a private company raising VC money to do research, which is ultimately should just be basic research, because the stuff that's going to be competitive and on the market probably can't happen until that first research happens.”
Yao: Manufacturing scale alone won't make sodium-ion cheaper than LFP
“It's not about scale. It's not about just taking the chemistries and sodium mine today and then scaling the hell out of it... What drives the cost at the end is the materials intensity... Just focusing on scale won't get us there.”
Kimber: Edge LLMs trigger recursive queries, massively multiplying datacenter power demand
“Every smaller distilled LLM that is power efficient doing inference is going to launch thousands of queries to bigger, more capable models that can actually reason their way through buying something on Amazon and reason. So it's almost like increasing the worl…”
Bullard: ESG acts as a negative screen, not an alpha-generating thesis
“ESG is a set of issues, but it's not the same thing as a set of drivers. You know, they're issues to be aware of, screens and filters on making institutional investment, which is different than A, you know, an alpha case reasoned to invest capital in something…”
Fernandez: Climate Startups Succeed by Deploying Tech Directly, Not Licensing
“What we found looking at over 300 projects, 350 projects in the past couple of years, is the fact that the companies that actually deploy their own technology and follow that path
Are the ones that get to success. There are companies that have spent two or thr…”
Fernandez: Skill shortage, not capital, is the biggest FOAK bottleneck
“My, our contention is that capital is an issue, but the biggest issue is the skill set that is required to be able to help the companies see a risk and really assess the risk of that big construction operation of first of a kind.”
Ball: Green tech startups falsely assume two-cent renewable power at 100% capacity
“If you're going to be in climate tech, you want to be green, and so you're almost certainly tethering yourself to a renewable source, which means your capacity factor isn't going to be a hundred percent. So it's kind of like having your cake and eating it, too…”
Thiel: New grid storage must hit $100-$150/kWh to beat 2030s LFP
“So I think that the numbers that we've landed on in, in our work are sort of in the hundred to 150 dollars per kilowatt hour total installed system cost. If you can see a path, a pretty clear path to those numbers, with your system, then you probably have a pr…”
Çubuk: Physical materials experiments are as noisy as computational simulation errors
“In material science, I think one of the issues is the experimental data is actually quite noisy. So, you know, this is something that you might hear often that simulations and DFT isn't very accurate, and that's true, but maybe one thing that People don't noti…”
