Digging deep for super hot geothermal

Despite its ability to deliver ample carbon-free energy, the potential of geothermal and EGS is limited by the number of drilling sites close enough to the earth’s surface. But a few pioneering companies have landed on a potential solution: dig way deeper. In this episode, Shayle speaks with Carlos Araque, the founder of Quaise Energy. The company has developed millimeter-wave drills to vaporize rock, allowing them to dig up to twelve miles underground in search of water around 800 degrees Fahrenheit. That super hot and "supercritical" water packs a huge punch: ten times more energy density than traditional geothermal. Shayle and Carlos explore a range of topics, including: Why 800 degree water is the “ideal” temperature for deep geothermal How "activating" permeability in deep rock differs from traditional fracking The state of Quaise’s Oregon project pilot, including their goal of a commercial-grade flow test by the end of 2026 How the LCOE of super hot geothermal compares to traditional baseload energy sources Resources Catalyst: How geothermal gets built Open Circuit: Is this geothermal’s breakout moment?

They’re at it again. Two years after they last teamed up for a Volts/Catalyst crossover episode, David Roberts joins Shayle for another far-ranging conversation exploring the future of energy. Their prompt was simple: Each host brought three critical questions they want to see answered in the next decade. From “data center fever” to closed-loop critical mineral economics, Shayle and David take the opportunity to dive deep into a myriad of second-order effects of the clean energy transition. In the hour-long conversation, the two hosts cover topics including: The coming explosion of self-driving cars, and whether it will fuel urban sprawl The feasibility of "electrifying everything” and whether a proliferation of “micro-DERs” in home devices will create create a more efficient grid or a software-fueled dystopia The future of off-grid data centers Whether the pros of geoengineering and solar radiation modification, or SRM, outweigh the potential moral hazards Resources: Catalyst: The Volts crossover episode Catalyst: The plug-in DER case for small businesses Catalyst: AMA: Geoengineering, nuclear, power prices, and more Open Circuit: Tesla’s fork in the road Latitude Media: The growing free-market push to let data centers go off grid Credits: Hosted by Shayle Kann.

For decades, the physical equipment underpinning the electric grid has remained largely unchanged: passive, "dumb" devices installed as far back as the 1970s that lack much real-time control. But today, in the face of skyrocketing energy demand, a new class of technologies has emerged. In this episode, Drew Baglino, the founder and CEO of Heron Power, returns to the show to discuss his company’s new generation of solid-state transformers, or SSTs. After a 17-year career at Tesla — where he led energy and powertrain development — Drew is now focused on replacing the grid’s aging infrastructure with these advanced power electronics. Shayle and Drew take a deep dive into the history of the power transistor, and then explore how the SST has the potential to transform the grid into a highly optimized and intelligent machine. They cover topics like: The evolution of power electronics Why we still haven’t fixed the transformer shortage How Heron Power’s SSTs remove legacy transformers and switches to create a substantial uplift for project developers The potential to remove 70% of traditional electrical equipment at data centers by distributing power directly to the rack Why Drew thinks SSTs offer a "pathway toward affordability" Resources Catalyst: Drew Baglino on Tesla’s master plan Latitude Media: Inside Heron Power’s plan to transform the grid Catalyst: Understanding the electric transformer shortage Open Circuit: The grid resilience dilemma Latitude Media: These Autogrid alums want to change how data centers use power Credits: Hosted by Shayle Kann.

Last year, the PJM capacity crunch became a focal point for an entire industry struggling to navigate the explosive growth of hyperscaler data centers. Yet even in the first two months of 2026, capacity prices have continued to skyrocket, and the economics of energy generation have only become more tenuous.  In this episode, Shayle Kann talks to Paul Segal, the CEO of LS Power. A major player in the space, LS Power owns a diverse portfolio of generation, storage, and transmission assets across the U.S. Shayle and Paul dive into the volatility currently defining the two most talked-about power markets in the country: PJM and ERCOT. They cover topics like: How PJM flipped nearly overnight from a state of "stasis" to a capacity shortage The federal government's emergency order to make large data centers "pay their way"  Why 10 gigawatts of expected load failed to show up during the recent Texas winter storm Why Paul sees ERCOT as a “cyclical” market that is currently difficult for new gas generation, despite massive load growth Paul’s strategy for ensuring sufficient “bridge” generation before new large-scale projects come online Resources Catalyst: PJM and the capacity crunch Latitude Media: PJM’s $178 billion fork in the road Catalyst: The potential for flexible data centers Credits: Hosted by Shayle Kann.

Spurred by a suite of executive orders and investments from the federal government, new nuclear reactors are coming soon. Or the announcements are at least.  The advanced nuclear sector has found itself in the spotlight as companies race to acquire licenses and permits aimed at achieving "criticality.” But what do these milestones signify? And is hitting the deadlines even feasible? In this episode, Shayle talks to Katy Huff,  former assistant secretary for nuclear energy at the Department of Energy and current associate professor at the University of Illinois. They unpack the wave of new nuclear announcements, the realities of navigating an arcane regulatory gauntlet, and what Katy considers a realistic timeline for new nuclear deployment. Shayle and Katy cover topics like: The NRC’s “murky” pre-application process The differences between various licensing pathways Why Katy views the DOE’s goal to have three reactors reach criticality by July 4th as “an extremely aggressive milestone” Upcoming revised guidance on nuclear radiation dose rates The challenges facing the DOE amidst a staff shortage Katy’s assessment of a feasible timeline for getting new reactors operational Why Katy doesn’t think microreactors are economically scalable…yet Catalyst: The US nuclear groundswell Open Circuit: Inside Meta’s massive nuclear push Latitude Media: The self-inflicted hurdles facing Trump’s nuclear orders Latitude Media: The Department of Energy’s 2026 playbook⁠ Credits: Hosted by Shayle Kann.

Distributed batteries are having a big moment. On one hand, companies like Base Power and Tesla have leaned into large residential batteries that export power back to the grid, but need permits and inspections to operate. At the same time, however, a new category has emerged: small, "plug-in" batteries that don’t require an electrician or complex installation, let alone a permit.  In this episode, Shayle talks to James McGinniss, co-founder and CEO of David Energy (yes, the biblical reference is intentional). David Energy is deploying these nimble, permissionless systems today for both residential customers and small businesses, and James argues that this approach could usher in a new era of massive scale and affordability for distributed energy resources. Shayle and James cover topics like: Why James prefers the term "plug-in" over "permissionless," and what falls into this bucket, from balcony solar to battery-enabled appliances The murky regulatory landscape around micro-DERs How plug-in systems can effectively drive soft costs (permitting, labor, customer acquisition) down to nearly zero How high energy prices in Germany drove the adoption of 4 million plug-in systems in just a few years The appeal for small businesses: how shaving just a few kilowatts of peak demand can generate significant savings for commercial customers in markets like New York Future form factors, including batteries integrated directly into cooktops, heat pumps, and other household appliances  Resources Catalyst: How Base Power plans to use its fresh $1B Catalyst: The new wave of DERs Catalyst: Is now the time for DERs to scale?

In 2024, Tom Burton described the clean energy transition as entering its “third inning” — a phase defined by execution and scale. A year later, the game looks very different. In this episode, produced in partnership with Mintz, Stephen Lacey sits down with Burton to revisit that framework and assess the state of play for U.S. energy infrastructure heading into 2026.  Burton, who chairs Mintz’s sustainable energy and infrastructure practice, brings nearly 3 decades of experience advising developers, investors, and operators across clean energy and digital infrastructure. They begin with the immediate market picture: a surge of renewable projects racing to put steel in the ground under existing tax rules, followed by a thinning pipeline. Burton explains why 2027 and 2028 could mark a slowdown in new deployments, even as demand continues to rise. From there, the conversation turns to politics. Federal hostility toward clean energy, shifting tax credit structures, foreign sourcing rules, and the weaponization of permitting have introduced new layers of risk. Deals are harder to close, financing is more complex, and even strong projects are feeling the strain. Burton unpacks what this environment means for developers, including who’s most exposed to the current shakeout, what separates resilient companies from struggling ones, and why permitting uncertainty may now be a bigger threat than tax policy itself. The episode also explores one of the defining forces reshaping the energy sector: the rapid expansion of digital infrastructure. Burton explains how power availability, interconnection, and long-term grid planning are now central to dealmaking. The energy transition hasn’t stopped, says Burton. But it has entered a rain delay — and the companies that adapt during the pause will be the ones still standing when play resumes. These conversations were recorded at the Mintz Energy Transition Summit. Mintz has been at the frontlines of the energy and sustainability revolution since the start.

For “deep tech” or industrial tech investors, a captivating idea on paper doesn’t always translate into a sustainable or viable business. Even a remarkable technological breakthrough isn’t guaranteed to survive the long sales cycles of the industrial world. So which companies are worth the investment? Ian Rountree, founder and partner at the venture firm Cantos, wrote a bare-bones thesis on X that offers guidance on this question. In it, Rountree lays out a stark list of the companies he invests in—and the ones he passes on. In this episode, Shayle and Ian unpack his post and explore how it applies to the current landscape of hardware and industrial startups. They cover topics like: Why selling technology to large incumbents like automakers or utilities can be a death sentence for startups The pitfalls of "commercializing science"  Why capital risk to sell an end-product can be better business than licensing technology Why "weird" companies—"N of 1" startups—can generate huge amounts of talent and capital Why selling commodities (like electrons or minerals) can actually be a safer bet than entering a new market Real-world examples of full-stack success in the mining industry, including Earth AI and KoBold Metals Latitude: Earth AI’s play in the hunt for critical minerals Catalyst: Calibrating hype with Akshat Rathi Catalyst: Climate tech startups need strong techno-economic analysis Open Circuit: Pain, resilience, and bargain hunting for climate tech investors Credits: Hosted by Shayle Kann.
