Jenkins: Displacing Russian gas with US LNG may not increase net emissions
“Even relying on US LNG to displace Russian pipeline gas may lead to a small net decrease in emissions because the greenhouse gas intensity of, Russian gas is so high that even LNG, which is worse normally than pipelines, because you consume energy to liquefy t…”
Bullard: Carbon removal is inherently a pure cost, requiring regulatory markets
“The challenge is that it is definitionally a cost. Like, it is definitionally a cost to remove carbon. And therefore, like, creating a market around that is a challenge, which is what, you know, the EU ETS did away with that by regulating it.”
Schroeder: Thermal storage IP cannot stop rivals using alternative cycles
“They might have intellectual property that prevents someone from directly copying what they're doing, but they can't stop all of these other people who could generate nominally the same performance from pursuing what they're pursuing.”
Dell: Urea Production Should Not Count as Meaningful CO2 Utilization
“A lot of people point to this as, like, the most important CO₂ utilization that is already commercialized in our economy, but that's actually a really problematic way of thinking about it, because the way you make urea, you start with a pure concentrated point…”
Shah: Climate tech startups understand equity but are unequipped for debt
“The vast majority of companies like Monolith that come into the loan programs office are experts at equity and not really well staffed on debt. And they don't really think debt, they think equity. And as a result, they think, The grass is always greener, and t…”
Lubershain: Gas utilities face a death spiral as volume declines
“And what that's manifesting in partially right now is like threats to natural gas where, you know, there's a lot of attention being paid to displacing natural gas... And then, you know, most importantly, it means that natural gas infrastructure owners with dec…”
Lubershain: Electrifying natural gas demand gets exponentially harder near 100%
“What you find in almost every use case, and I would say in particular Again, in the distributed use cases like building heating is that, you know, maybe the first, you know, the first 50% of gas demand that you soak up with electrification is relatively easy. …”
Kann: Cleantech 1.0 losses were concentrated in thin film, biofuels, and Better Place
“So the big categories of where the money pits in cleantech one.o were thin film solar. Like you said, alternatives to silicon for PV, biofuels, and then one big money pit, which was, you said battery swapping, it was Better Place... If you subtract those three…”
Naam: Deep tech startups no longer need commercial scale to exit
“It's no longer the case that we have to wait all the way until we have a product commercially on sale or at scale for this to produce an exit.”
Naam: App-based software businesses have weaker moats than hard tech
“We used to believe that, or companies like, again, I'll say Uber or WeWork, we thought, oh, they have natural network effects, they're gonna have a gigantic moat but it turns out switching costs for consumers are actually pretty low, and maybe lower, And some …”
Lubershain: Data center growth inflates utilities' non-negotiable grid maintenance costs
“Two-thirds of the expenditures they're making today across utilities are non-negotiable, and it's, Has nothing to do with growth, right? All that stuff would be happening even if the data center, boom, were not happening. And so, all that stuff is getting more…”
Janous: Taking data centers off-grid prevents broader electricity rates from decreasing
“It's fine micro, but I would even say, I mean, if you believe that a larger denominator is actually good for lowering electricity rates over time, it's actually negative in that you're taking that denominator off the grid.”
Tillis: Both Green Energy and Drilling Have a Place in Transition
“You need to recognize that we are in a transition. And this bullshit of, it's gotta be green, and drill, baby, drill, is the problem. Both have a place.”
Quantum computing offers scientific explainability and reproducibility currently lacking in AI
“It, it's, it, a large language model and its training and inference phases are completely opaque. You can't say, why did you give me this solution versus this one? And if I just change a variable slightly, what will be the outcome? Non-reproducible results, no…”
Yedvab: Safe geoengineering alternatives reduce the risk of rogue deployments
“I believe that having a safe option essentially lowers the risk That people will go the wrong way because there is an alternative. Or to say it otherwise, if we didn't have options, I would say that the likelihood that someone would go the wrong way would be m…”
Yedvab: Having no geoengineering options is worse than moral hazard risk
“I would argue that, you know, Having no option is not a good balance for this. You need to have options. You want to make sure that you are not stuck in a position that in 10 years from now, people are saying, why no one worked on, on giving us option?”
Ocean convective cooling eliminates traditional data center cooling infrastructure costs for Panthalassa
“We are actually in a resource that gives us free, extremely good convective cooling, and that's huge, because it essentially lets you eliminate the entire cost structure of the data center. And our object is actually replacing both power plant and data center,…”
Von Munch: Inertial fusion plants can improve without building new capital infrastructure
“The interesting thing about inertial technologies, and our technology in particular, is that you can improve the performance and reduce the effective cost of existing facilities just by adding new improved fusion targets. So those fusion targets are going to c…”
Von Munch: Milestone-gated financing requires clear terminal value but unpriced intermediate steps
“I think the, there are two things that kind of have to be true for a structure like this to make sense. I think one of them is that you have to have Very high conviction in how the market will value this big end thing. Or not end thing, but like this big inter…”
Cohen: Highway stops for confused autonomous trucks are highly dangerous
“When, in San Francisco, when a passenger car stops, you know, people go around and they honk, they call they call annoyed their local politicians, whatever, but mostly it's a safe situation. You don't have that advantage on a highway. So, so, so stopping a tru…”
Cohen: Hub-to-hub autonomous freight faces economic hurdles from depot friction
“The challenge in that is, today, you don't have those depots, and somebody has to build those depots, and those depots are friction. Like, who is moving the freight to that depot And why do they want to move into that depot, as opposed to just what they do tod…”
Hershman: Solar installation is closer to manufacturing than traditional construction
“I think we look at our business much more akin to manufacturing than we look at it as construction, right?
You think about, we are, we're trying to do this, a, the same activity a million times, and how do we do that just
Slightly more efficient.”
Hershman: Truck logistics, not labor, is solar construction's primary bottleneck
“The amount of trucks that we have to move becomes the gating activity, not the amount of people, right?”
Shafer: TRISO fuel resists leaching, whereas molten salts require waste conditioning
“Triso, again, is a wonderful waste form for all the reasons that people love it as a fuel form, right? The radioactive material is not getting out when it's reacting in the reactor, and it's not getting out when it's Sitting on the side of the building. Howeve…”
Araque: Drilling super-hot geothermal is a vastly larger hurdle than fracturing
“The drilling by far outweighs the fracturing. The fracturing does happen in nature. We see this in nature every time a hydrothermal vent or a mine forms. This is the process by which it does so. So there's evidence in the geological record that The fracture in…”
Siegel: Battery saturation in ERCOT has compressed incremental investment returns
“A couple of years ago, we transitioned Intercut from a market that relies heavily on ancillary services to support batteries, and that was very robust. We built into that. That market was overwhelmed with supply, and then when you move out of the sort of small…”
Rountree: Startups with customer sales cycles over 18 months are de facto dead
“The main reason that startups are time limited is because you raise serially in, like, you know, whatever, you raise 18, 24 months of runway, and so, let's say you raise 24 months of runway, you need to start fundraising, let's say, six months before you run o…”
Rountree: Perfecting Technology in the Lab Delays Crucial Commercial Learning
“One of the things I didn't see there is that the learning curve matters. And once you start doing a thing, you tend to get better at it. And if you're commercializing something at small scale, you're kind of working out all the kinks that if you're, you know, …”
Rountree: Selling software to legacy industries limits operational innovation
“Every single time we've invested in a capable team or watched a capable team go after an industry with a lot of inertia there are a thousand little things that can be improved upon that if you're not, Taking that on, and you're just selling into the industry, …”
Battaglia: AI weather models leverage macroscopic spatial ranges unlike traditional simulations
“In a traditional model, the way it simulates that is it, in very fine detail, it kind of figures out, like, what's the pressure, and the temperature, and the wind, and the moisture, and what are those things? What's going to happen next is determined strictly …”
Shifting inference to edge data centers will reduce efficiency and increase energy costs
“I think as you shrink the system down, you will get, you will lose an efficiency. You will be trying to build these 20 megawatt data centers and maybe footprints or facilities that weren't designed initially for those workloads. So yes, I think total energy co…”
Modon: High engineering costs force projects into single-pass local optima
“Because again, such a high marginal cost to engineering, what you end up doing is you only really design something one pass through. There's no sort of iteration. There's no optimization of design. And that leads you to a spot where you kind of make early deci…”
Matthew: Power constraints widen Nvidia's total cost advantage over less efficient chips
“Because since we are power constrained and that constraint is expected to get worse and power prices rise, the NVIDIA chip holders actually, like the TCO advantage that they have versus less efficient chips actually goes up in that scenario, right? So they act…”
Lubershain: High oil and gas prices drain drillers from geothermal projects
“I actually think to some extent, the timing and the pace of geothermal deployment might also depend on the alternative for that skilled workforce.
So like high oil and gas prices, really rich, rich oil and gas market, harder to convince drillers to
To go to wo…”
Sridhar: Tech value creation only happens when workloads move to the edge
“While things start In a very centralized fashion far away, ultimately the value is only created and the growth comes when that technology comes to the edge, closer to where people are, closer to where machines are, closer to where people are, and that is the p…”
Dell: Decoupling mounting from electrical work cuts battery installs to two hours
“You can break apart the insulation. You can have a truck driver show up, do the racking, stacking, and mounting mount a box to the wall where the hot work happens, and then an electrician shows up the next day and does the hot work in, you know, 30 minutes. An…”
Guernsey: Co-locating capacity at grid constraints helps solve data center bottlenecks
“This notion of, like, on-site versus off-site can be a little bit more flexible if you're willing to take into account the fact that as long as you're co-locating at the constraint, that's solving the problem, and now you have more tools in your toolkit, inclu…”
Reinhardt: High EBITDA per ton companies will lead carbon removal adoption
“If you look at a sort of chart of, like, profitability per ton or EBITDA per ton, like, it's the companies that have a lot of EBITDA per ton that are going to lead the way on helping things down.”
Transmission lines act as direct substitutes for local baseload power generation
“The transmission line itself is a substitution for baseload power, because if you can move more power over more space, you are Reducing the need to have to generate that power on the other end of that congestion. So in that sense, transmission and generation a…”
Current grid operators lack the institutional experience to manage rapid load growth
“I don't think that really anyone has got the muscle for this because it's not been in anybody's lived experience really. And so we're having to think about it pretty fresh.”
Data centers tolerate power price hikes far better than industrial steelmakers do
“If you jack the price of electricity, 30% for somebody that makes steel using an electric arc furnace, it will materially impact the cost of the steel that is being made. If you do the same for people that are doing data center operations especially for traini…”
Kelty: LFP batteries have little room left for major improvements
“LFP's been around now, For 20 odd years, it's been commercialized. They've come down that cost curve over time, and so there's not a whole lot of improvements that you can make with LFP. You've got to jump to a new chemistry.”
Hyperscalers and AI power demand will enable US nuclear deployment
“Back in the 2000, there was not really any demand growth. Now we're seeing phenomenal demand growth, which was strong to begin with, but just, I mean, really taken off with artificial intelligence driving it. And, you know, those trillion dollar balance sheet …”
Multi-unit SMR sites reduce factory and field cost curves faster
“And when you have multiples at a site and multiples in a deployment, you can get down those cost curves both in the factory and in the field more readily than you could with a large reactor.”
Regulated utilities cannot take nuclear development risk with returns capped at 10%
“You know, what I hear from utilities now is what I heard from utilities back in the past, right, is that, you know, they fundamentally can't take development risk. And, you know, that's a, having done fossil plant development, I did that for 15 years of coal a…”
Brown: Large VPPs remain predictably stable even with individual customer control
“When you give individuals control, large, long system, and you have hundreds of thousands of customers or a million customers, you know, stochastically we can predict, you know, how these things will perform in aggregate. And so actually having control the ent…”
Friedmann: Gas CCS is most expensive per ton, cheapest per MWh
“If you think about it in terms of dollars per ton, natural gas is the most expensive. If you think about it in terms of dollars per megawatt hour, it's actually the least in the power sector.”
Stadler: Standalone gas or diesel generators become stranded data center investments
“You might think that installing just a small gas generator, diesel generator might be the solution, but it's actually kind of stranded investment. Because, I mean, after, let's say the utility comes online and gives you the power of three or four years, you ha…”
