Green Giants: Titans of Clean Energy Podcast

What if the biggest battery breakthrough for AI isn't about storing more energy, but delivering power faster?

AI data centers aren't just consuming more electricity. They're fundamentally changing how electricity needs to be delivered. As GPU clusters create sudden, high-intensity power demands, the infrastructure supporting them faces challenges traditional energy storage wasn't necessarily designed to solve.

In Episode 125 of Green Giants: Titans of Renewable Energy, host Wes Ashworth, President of Lee Group Search, sits down with Tod Higinbotham, CEO of ZincFive, to explore why a century-old battery chemistry is finding new relevance in one of the world's fastest-growing industries.

ZincFive specializes in nickel-zinc battery technology designed for immediate, high-power applications. Tod explains why the distinction between power and energy matters more than ever, how short-duration battery systems can help manage AI-driven demand spikes, and why the future of energy storage may involve increasingly specialized and hybrid technologies.

But this conversation goes far beyond batteries.

Drawing on more than three decades commercializing advanced materials across semiconductors, solar, and energy storage, Tod reveals how breakthrough technologies often find their greatest commercial value in markets their creators never anticipated.

The discussion also tackles the growing tension between AI infrastructure expansion and electricity availability. From grid modernization and nuclear power to manufacturing in China, building U.S. production capacity, and the environmental lessons Tod learned growing up in Butte, Montana, this episode examines what responsible electrification actually requires.

With ZincFive surpassing 2 gigawatts of power delivered or contracted, Tod also shares the realities of scaling battery manufacturing, attracting capital, developing leadership, and turning promising science into a sustainable business.

In This Episode, You'll Discover:

• Why AI is changing the battery equation: How rapid GPU power fluctuations create opportunities for immediate-power storage rather than conventional long-duration batteries.
• The nickel-zinc advantage: Where nickel-zinc batteries fit alongside lithium-ion, lead-acid, and supercapacitors, and why chemistry specialization matters.
• The economics of smarter infrastructure: How managing power spikes closer to computing loads could reduce the need to build electrical systems around brief peak demands.
• Battery safety beyond the headlines: What thermal runaway means, how UL 9540A testing works, and why electrical safety remains essential.

AI is creating an enormous demand for electricity. But what if the bigger challenge isn't just how much power data centers need, but how quickly that demand changes?

In this episode of Green Giants: Titans of Clean Energy, host Wes Ashworth, President of Lee Group Search, sits down with Dr. Raj DasGupta, CEO of Electrovaya, to explore why AI infrastructure is creating an entirely different opportunity for advanced battery technology.

Raj has spent nearly two decades in the lithium-ion battery industry, moving from materials science and R&D into manufacturing, business development, operations, and ultimately leading Electrovaya. Along the way, he's learned that building a better battery isn't simply about storing more energy or lowering costs.

It's about solving the right problem.

While much of the battery industry has focused on producing cheaper energy storage, Electrovaya has taken a different path, developing high-performance batteries for demanding industrial applications where safety, longevity, reliability, and power matter most.

Now, with AI data centers experiencing dramatic fluctuations in electricity demand, that strategy is opening the door to an entirely new market.

Wes and Raj explore how Electrovaya's ElvaPulse high-power energy storage platform is designed to help manage those fluctuations, why the economics of battery storage are changing, and what it takes to bring advanced lithium-ion manufacturing back to the United States.

In this episode:

• Why Electrovaya deliberately stepped away from commodity battery markets and how that decision shaped its future
• The hidden electricity challenge facing AI data centers and why conventional energy storage isn't always the ideal solution
• Understanding power versus energy, and why dollars per kilowatt can matter more than dollars per kilowatt-hour

What if one of the biggest opportunities in clean energy is not discovering a new energy source, but making the sunlight already reaching us more useful?

In this episode of Green Giants: Titans of Renewable Energy, Wes Ashworth, President of Lee Group Search, sits down with Hunter McDaniel, Founder and CEO of UbiQD, to explore how quantum dots are moving from advanced materials research into real-world applications in agriculture, solar, and large-scale manufacturing. 

Hunter’s path began in physics, electrical engineering, and materials science, eventually leading to a Ph.D. in Materials Science and Engineering and postdoctoral research at Los Alamos National Laboratory. What started as highly specialized work in semiconductor nanocrystals became the foundation for UbiQD, a company built around a simple but powerful idea: use nanoscale materials to control how light behaves. 

Wes and Hunter break down quantum dots in practical terms, including how changing particle size can change the color of light they absorb and emit. That capability creates a platform for spectrum engineering, where sunlight can be tuned before it reaches a plant or solar cell.

In agriculture, UbiQD’s UbiGro technology shifts portions of sunlight toward wavelengths that can improve plant performance. Hunter discusses greenhouse trials across multiple regions, what growers actually care about, and why the future may involve different light recipes for different crops. 

The conversation then moves into solar, where the scale becomes dramatically larger. Hunter explains how quantum dots can target underutilized portions of the solar spectrum, why even modest performance improvements can create meaningful economic value across millions of panels, and what has to be proven before a major solar manufacturer will trust a new material inside a product expected to operate outdoors for decades.

They also explore UbiQD’s expansion through its acquisition of BlueDot Photonics technology, including the emerging concept of quantum cutting, where one high-energy photon can potentially produce nearly two lower-energy photons better suited for solar conversion. 

But the heart of the episode is not just the science. It is the challenge of turning science into industry.

Hunter shares what changes when a company moves from making small research batches to operating reactors, managing supply chains, qualifying materials with customers, building manufacturing capacity, and preparing for production measured in tons rather than grams. UbiQD’s recent growth, capital raises, expanded Los Alamos footprint, and long-term solar supply ambitions illustrate just how different deep-tech scale-up is from traditional software growth. 

This episode covers:

• How quantum dots change the way light behaves
• Why spectrum engineering matters in both agriculture and solar
• How greenhouse light manipulation can influence crop performance
• Why small efficiency gains can matter enormously at utility scale
• The difference between standard fluorescence and quantum cutting
• What it takes to prove durability for materials expected to last decades
• How an R&D company becomes a manufacturing company
• Where promising national-lab technology can get lost before commercialization
• Why advanced materials may play a major role in the next wave of clean energy innovation

For anyone interested in solar, advanced materials, climate technology, deep-tech commercialization, or the future of domestic manufacturing, this conversation offers a rare look at what it actually takes to move a scientific breakthrough from the lab into infrastructure-scale deployment.

Why Nuclear's Moment Is Now: Stefano Buono, CEO of newcleo

For newcleo founder and CEO Stefano Buono, nuclear energy's next chapter has been more than 30 years in the making. Now, rising electricity demand, energy security concerns, and changing attitudes toward nuclear are creating an opening for ideas he began pursuing in the 1990s.

In this episode of Green Giants: Titans of Clean Energy, host Wes Ashworth, President of Lee Group Search, sits down with Buono to explore what makes this nuclear moment different and what it will take to turn that momentum into commercial projects.

A physicist and entrepreneur, Buono previously founded Advanced Accelerator Applications, the nuclear medicine company acquired by Novartis for approximately $3.9 billion. He shares how that experience prepared him to return to his original ambition: developing a different approach to nuclear energy.

Today, newcleo is developing lead-cooled fast reactors designed to use recycled nuclear fuel. Buono explains the technology in accessible terms, including why useful energy remains in spent fuel, how liquid lead supports the company's approach to passive safety, and why the economics of recycling matter.

The conversation also tackles the difficult questions: plutonium security, the history of costly U.S. fuel projects, regulatory approvals, and the challenge of financing and building an entire reactor and fuel supply chain.

In this episode:

• Why decarbonization, energy independence, and AI-driven electricity demand are reshaping nuclear's opportunity.
• How lead-cooled fast reactors differ from conventional nuclear plants.
• What recycled mixed-oxide (MOX) fuel could mean for fuel supply and nuclear waste.
• newcleo's proposed work with Oklo and its ambitions at Savannah River.
• Why industrial heat and manufacturing matter alongside data centers.
• The milestones that will show whether newcleo is moving toward commercial deployment.
• Buono's advice for founders building technologies that take decades to reach the market.

Release update: This conversation was recorded ahead of newcleo's Nasdaq debut. The company subsequently completed its business combination with NewHold, securing approximately $247 million in gross proceeds, and began trading under NWCL on September 22, 2026.

For energy leaders, founders, and anyone curious about advanced nuclear, this episode connects the science to the practical work of bringing new energy projects to life.

The nuclear renaissance is about far more than building reactors.

It is also about capital, fuel security, recycling, infrastructure, commercialization, supply chains, workforce, and whether the energy system can scale fast enough to meet a new era of electricity demand.

In this episode of Green Giants: Titans of Clean Energy, Wes Ashworth, President of Lee Group Search sits down with Michelle Urben, Managing and General Partner at The Synergos Fund, to explore what it will actually take to finance and build the next generation of energy infrastructure. 

Michelle brings more than three decades of experience across banking, asset management, investor relations, and venture capital. Her path from the Philippines and an oil-industry family to Wall Street and deep-tech investing gives her a unique perspective on energy affordability, energy security, and the role patient capital can play in solving foundational infrastructure challenges.  

The conversation begins with a fundamental investing question: Is traditional venture capital structured for technologies that may require years of technical validation, regulation, demonstration, and infrastructure before reaching full commercialization?

Michelle explains how The Synergos Fund approaches that challenge through milestone-driven investing, long-term alignment, active participation, and a focus on durable companies across energy, manufacturing, food, and health.

From there, the discussion moves into one of the most overlooked pieces of nuclear energy: the fuel cycle.

Michelle shares why nuclear recycling company Curio became such an important part of her transition into deep tech and why she believes spent nuclear fuel should increasingly be viewed as a strategic energy resource rather than simply as waste. The conversation explores fuel security, domestic nuclear supply chains, recycling, commercialization, and the broader ecosystem required around the reactor itself. 

Wes and Michelle also examine the massive increase in electricity demand being driven by AI, data centers, reshoring, and electrification. If generation, grid infrastructure, and behind-the-meter solutions cannot keep pace, the constraint may increasingly become access to reliable power.

They also discuss Gate 5, a wastewater-to-energy technology in the Synergos portfolio, as an example of a broader investment philosophy: finding valuable energy resources in places the traditional system often treats as liabilities. 

But technology and capital alone will not build the next energy system.

The episode closes with one of the most important constraints facing the industry: people. Engineers, welders, electricians, operators, technicians, construction professionals, regulators, and other skilled workers will all be necessary to turn ambitious energy plans into functioning infrastructure.

In this episode:

•  Why Michelle moved from traditional finance into nuclear and deep tech 
•  What patient capital should demand from infrastructure companies 
•  Why timing matters in private-market investing 
•  The nuclear fuel-cycle opportunity beyond the reactor 
•  Why spent nuclear fuel could become a strategic resource 
•  How AI and data centers are reshaping electricity demand 
•  Wastewater-to-energy and the opportunity behind overlooked resources 
•  Why commercialization requires strong operators, not just investors 
•  The workforce challenge facing nuclear and energy infrastructure 
•  Why the companies quietly building through difficult problems may ultimately shape the next energy era 

For investors, founders, energy executives, and anyone thinking seriously about the future of nuclear power and energy infrastructure, this episode offers a much broader framework for understanding what the next energy system will actually require.

Breakthrough science is only the beginning. The harder challenge is turning promising technology into a system that can operate reliably, economically, and repeatedly in the real world.

In this episode of Green Giants: Titans of Clean Energy, Wes Ashworth, host and President of Lee Group Search sits down with Tina Tosukhowong, Investment Director at TDK Ventures, to explore what separates deep-tech companies that scale from those that stall between the lab, pilot plant, and first commercial facility. Tina brings an unusually valuable perspective to venture investing. Before becoming an investor, she spent years as a chemical engineer and industrial operator working across process development, pilot operations, scale-up, commercialization, manufacturing, and customer qualification.  

That operating experience shapes how she evaluates climate tech, advanced materials, AI infrastructure, and other capital-intensive technologies today.

Tina explains why scaling is not simply a matter of building a larger version of a successful pilot. At commercial scale, entirely new risks emerge around heat transfer, fluid flow, contamination, materials handling, uptime, permitting, utilities, feedstocks, safety, supply chains, and integration with customer sites. The companies that succeed are often the ones that identify failure modes early, run the right experiments, and learn faster than their capital disappears. 

The conversation also tackles one of the most important questions in deep tech: When has a company actually earned the right to scale?

Wes and Tina explore why raising too much money too early can be dangerous, how founders should think about risk retirement before committing hundreds of millions of dollars to a first commercial plant, and why the strongest financing strategy aligns capital with specific learning milestones. They also discuss founder-market fit, coachability, executive hiring, productive board conflict, and why the right investor syndicate can matter as much as valuation. 

The discussion then moves into the rapidly evolving physical infrastructure behind AI. Tina breaks down opportunities across data-center power delivery, energy storage, cooling, thermal materials, networking, semiconductors, and photonics. She explains why the next wave of AI infrastructure innovation may come not only from better chips, but from everything required to power, connect, and cool them efficiently.  

The episode also explores fusion energy, synthetic fuels, critical minerals, and frontier technologies, including Tina’s perspective on Type One Energy, INERATEC, and the growing overlap between clean energy, computing, advanced materials, manufacturing, and national supply-chain resilience. 

In this episode, you’ll learn:

•  Why industrial scale-up exposes risks that laboratory success cannot predict 
•  What founders should prove before committing to a first commercial facility 
•  How capital discipline can prevent expensive first-of-a-kind mistakes 
•  Why learning speed and coachability matter so much in deep-tech leadership 
•  When experienced executives help startups and when they can slow them down 
•  Why investor syndicates and boards become critical when plans break 
•  Where Tina sees overlooked opportunities in AI data-center infrastructure 
•  Why cooling, rack-level power conversion, and photonics could become major bottlenecks 
•  What industrial operating experience reveals about the future of fusion 
•  How e-fuels, critical minerals, AI, and advanced materials are increasingly converging 

For founders, investors, operators, and leaders building the next generation of clean energy and deep-tech companies, this episode is a practical look at what it really takes to move from possibility to commercial reality.

What if the next major battery breakthrough does not require a new chemistry, a new factory, or an entirely new manufacturing ecosystem?

In this episode of Green Giants: Titans of Renewable Energy, Wes Ashworth sits down with David Mackanic, Co-Founder and CEO of Anthro Energy, to explore why the electrolyte may be one of the most overlooked levers in battery performance. 

Anthro Energy is developing Proteus, a phase-change electrolyte designed to enter a battery cell as a liquid and then solidify during formation. The goal is to improve safety, mechanical stability, swelling behavior, and compatibility with higher-energy chemistries while using existing lithium-ion manufacturing equipment. 

David explains why this approach could matter for everything from silicon-rich batteries and consumer electronics to EVs, robotics, defense, autonomous systems, and physical AI.

The conversation also gets into one of the biggest challenges in battery innovation: making something work not just in a laboratory, but consistently, economically, and at industrial scale.

Wes and David discuss:

• Why the electrolyte has historically received less attention than the anode and cathode
• How Proteus transitions from liquid to solid inside the battery cell
• Why "drop-in" manufacturing does not mean zero process changes
• How mechanical stabilization can help address silicon expansion, cracking, swelling, and degradation
• Why better batteries require progress across energy density, safety, cycle life, and manufacturability at the same time
• How Anthro thinks about reducing both the frequency and severity of battery safety events
• Why a more expensive electrolyte can still create greater value at the full cell and application level
• Why robotics, autonomous systems, defense, and physical AI create a different battery problem than conventional EVs
• How structural batteries could eventually change the architecture of products themselves
• How Anthro Atlas uses AI to explore enormous electrolyte design spaces and accelerate materials development
• Where AI predictions still have to prove themselves against real-world chemistry and manufacturing
• What changes when a materials science company moves from discovery into production
• Why Anthro is scaling advanced electrolyte manufacturing in the United States
• Why the future of batteries is unlikely to be defined by one winning chemistry

David’s background spans mechanical engineering, chemistry, polymer science, and advanced battery research, including a Ph.D. in chemical engineering from Stanford focused on polymer systems for safer, longer-lasting, higher-energy lithium-ion batteries. 

This episode is a deep look at the intersection of battery technology, advanced materials, AI-driven discovery, U.S. manufacturing, energy storage, robotics, and the future of electrification.

Most of the buildings we will depend on for the next several decades are already standing. That makes the next phase of building decarbonization less about showcase new construction and more about upgrading the systems hidden behind walls, beneath floors, and underground.

In this episode, Wes Ashworth sits down with Mike Richter, President of Brightcore Energy, to explore geothermal heating and cooling as a practical building-performance strategy. Mike brings a rare perspective to the conversation. After a 15-year NHL career that included a Stanley Cup championship and Olympic medal, he built a second career focused on climate, energy efficiency, and the built environment.

Mike explains the critical difference between geothermal power generation and the ground-source systems used to heat and cool buildings. He breaks down the physics in accessible terms, then shows how smaller drilling rigs, directional drilling, hybrid systems, advanced controls, and real-time data are expanding what is possible in dense cities and occupied buildings.

The conversation also examines why retrofits are the true test of decarbonization. Existing buildings come with aging infrastructure, limited space, complex load profiles, and owners who often wait until equipment fails before considering alternatives. Mike outlines why early evaluation matters and why every geothermal project must be designed around the building, geology, distribution system, operating needs, and financial horizon.

In this episode, you will learn:

• Why geothermal HVAC is different from deep geothermal power
• How the ground can function as a stable heat source, heat sink, and thermal battery
• Why urban and occupied-building retrofits are becoming more feasible
• How Brightcore integrates engineering, drilling, controls, implementation, and performance monitoring
• What The Beresford project demonstrates about geothermal in a historic New York City building
• Why one-directional cooling loads, including data centers and ice rinks, create new design challenges
• How Local Law 97 is changing capital planning for New York City building owners
• Why education, perceived risk, financing, and timing remain major barriers to adoption
• How better building systems can reduce operating costs while improving comfort, air quality, and performance

Mike offers a grounded view of the market. Geothermal can deliver major efficiency and emissions benefits, but it is not a universal, one-size-fits-all solution. The opportunity depends on sound engineering, realistic economics, thoughtful integration, and a willingness to evaluate options before an emergency replacement locks a building into another generation of legacy equipment.

This episode is essential listening for professionals in commercial real estate, facilities, engineering, higher education, government, finance, climate policy, and renewable energy who want to understand how geothermal retrofits can move from niche technology to mainstream building infrastructure.

Nuclear energy is having another moment. But enthusiasm alone will not create a nuclear renaissance.

The bigger question is whether the industry can finally learn to deliver complex projects predictably, repeatedly, on time, and at a cost investors and utilities can accept.

In this episode of Green Giants: Titans of Renewable Energy, host Wes Ashworth, President of Lee Group Search, sits down with Tony Roulstone, Lecturer in Nuclear Engineering at the University of Cambridge and former Group Managing Director of Rolls-Royce Nuclear Engineering.

Tony brings decades of experience spanning nuclear energy, aerospace, complex engineering programs, business transformation, and nuclear education. That perspective leads to a fascinating argument: the biggest breakthroughs nuclear needs may have less to do with reactor physics and more to do with how reactors are manufactured, financed, constructed, and repeated.

The conversation begins with a Rolls-Royce aerospace failure that left Boeing 747s waiting for engines. The technology problem ultimately exposed a deeper organizational problem. Tony explains why that lesson still matters for nuclear projects today.

From there, Wes and Tony examine one of nuclear energy's fundamental challenges. Building a large reactor can resemble manufacturing an aircraft in a field. Thousands of people, intricate supply chains, enormous documentation requirements, specialized inspections, and long construction timelines make repetition and productivity incredibly difficult.

That is where small modular reactors, or SMRs, could change the equation.

Tony explains why smaller does not automatically mean cheaper and why the real economic opportunity behind SMRs depends on three principles:

• Standardization: Stop redesigning the product for every customer and site.
• Modularization: Move significantly more construction into controlled factory environments.
• Production learning: Build repeatedly enough for teams, suppliers, and processes to improve from one unit to the next.

The discussion also explores advanced nuclear reactors, including high-temperature gas reactors, liquid-metal systems, and molten salt concepts, along with what new reactor technologies could mean for safety and industrial applications.

Tony and Wes also confront nuclear's most persistent public challenge: trust. They examine lessons from Chernobyl, the importance of organizational safety culture, and why modern nuclear safety cannot be understood solely through the industry's historical accidents.

Finally, they tackle the false choice between nuclear energy and renewable energy. Deep decarbonization will require an entire energy system, including electricity, industrial heat, transportation, storage, renewables, and firm low-carbon generation. The real question is not which technology wins. It is how these resources work together.

In this episode:

• Why technically brilliant projects can still fail
• What aerospace can teach nuclear about systems engineering
• Why large nuclear construction struggles with productivity
• The real economics behind small modular reactors
• Why SMRs require fleet deployment and repeatable production
• Standardization, modularization, and manufacturing learning
• Advanced nuclear reactor technologies and their potential
• Nuclear safety, Chernobyl, and public confidence
• Private capital and the growing nuclear ecosystem
• Why nuclear and renewables should not be treated as opposing camps
• What nuclear must accomplish by 2035 to prove it can truly scale

The ultimate test is simple: nuclear must become predictable.

If the industry can turn extraordinary engineering projects into repeatable industrial products that arrive when promised and near the cost promised, nuclear could play a much larger role in the global energy transition.

The energy transition is usually framed around generation, storage, transmission, permitting, and capital. But one of the biggest constraints may be hiding in plain sight: the physical materials required to build everything.

In this episode of Green Giants: Titans of Renewable Energy, Wes Ashworth, President of Lee Group Search, sits down with Bryan Guido Hassin, Co-Founder and CEO of DexMat, to explore why the future of electrification, renewable energy, AI data centers, grid expansion, aerospace, and advanced manufacturing may depend on a fundamental materials transition. 

Bryan brings an unusually broad perspective to the conversation. His career has spanned software entrepreneurship, energy technology, climate innovation, venture ecosystems, and deep tech. He also co-founded Third Derivative, where exposure to hundreds of climate technologies helped reveal a recurring challenge: nearly every major electrification pathway depends on rapidly scaling conductive materials such as copper, while supply, performance, and production constraints continue to intensify.  

That realization ultimately helped lead Bryan to DexMat and Galvorn, an advanced carbon material made from aligned carbon nanotubes. DexMat is developing Galvorn for applications where conductivity alone is not enough and properties like low weight, strength, flexibility, heat dissipation, corrosion resistance, and durability become critical. 

In this conversation, Wes and Bryan explore:

• Why copper could become a major bottleneck for electrification and renewable energy growth
• How AI data centers add another layer of pressure to materials demand
• Why mining and recycling more copper may help, but may not solve the full problem
• How Galvorn is made and why carbon nanotube alignment is the key breakthrough
• Where Galvorn can compete with copper today and where copper still has advantages
• Why conductivity must be evaluated alongside weight, heat, strength, frequency, and system design
• How wet fiber spinning could help advanced carbon materials scale economically
• The qualification hurdles behind aerospace, defense, medical, grid, and wire-and-cable adoption
• Why hard-tech commercialization requires manufacturers, investors, policymakers, and customers to move together
• What investors often misunderstand about materials startups
• How entirely new materials can unlock designs that were previously impossible

Bryan also shares the personal journey behind the work, including the influence of Nobel laureate Rick Smalley at Rice University and how a career spent studying climate innovation ultimately brought him full circle into advanced materials. 

The bigger idea is simple but consequential: building a cleaner, more electrified economy requires more than changing how we generate energy. It may require changing the materials civilization is built on.

For anyone working in renewable energy, grid infrastructure, AI infrastructure, electrification, climate tech, advanced materials, deep tech, or industrial innovation, this episode offers a very different lens on what could determine the speed of the energy transition.
