In this episode of Green Giants: Titans of Renewable Energy, host Wes Ashworth sits down with Joe Adiletta, CEO of Volexion and a veteran of the battery world, to explore what it really takes to commercialize deep tech innovation in one of the most capital-intensive and strategically vital industries of our time: lithium-ion batteries.

With two decades of experience spanning A123Systems, 24M, Ionic Materials, and now Volexion, Joe brings a rare blend of hard-won insight and strategic clarity. This isn’t a conversation about hype. It’s about navigating the messy, capital-constrained, slow-moving reality of energy storage innovation and doing it anyway.

Volexion’s approach? A conformal graphene coating, what Joe describes as a “wetsuit for cathodes.” It’s a subtle but powerful manufacturing innovation that improves battery performance without overhauling production lines. And it’s gaining traction globally.

But this episode goes far deeper than the tech. We unpack what it takes to build hard tech startups in the U.S., close the missing-middle funding gap, and lead teams through the emotional rollercoaster of building the next generation of industrial infrastructure.

In this episode, we cover:

• Why the cathode, not the anode, may be the most underleveraged opportunity in battery innovation
• How Volexion’s “small change, big impact” strategy drives measurable results with minimal disruption
• What it takes to turn university research into commercial materials shipped around the world
• The brutal realities of funding first-of-a-kind facilities and what hard tech really needs from investors
• Why battery breakthroughs haven’t followed the step-change model of software and why that’s okay
• How Joe leads through uncertainty and builds resilience inside small, mission-driven teams

Why it matters:
Energy storage is foundational to the electrification of everything. Battery innovation is a national priority. But meaningful progress doesn’t always look like sci-fi headlines. Sometimes, it’s a quiet revolution in materials science, backed by great people and smart capital.

Whether you're a battery nerd, an energy investor, or a founder navigating the tough terrain of cleantech startups, this episode is a must-listen.

What if the key to unlocking nuclear energy’s future has been buried all along?

In this episode of Green Giants: Titans of Renewable Energy, host Wes Ashworth dives into one of the most overlooked and misunderstood challenges of the clean energy transition: nuclear waste disposal.

His guest, Rod Baltzer, is a 25-year veteran of the nuclear waste industry and now CEO of Deep Isolation, a company pioneering deep horizontal borehole disposal for spent nuclear fuel. With a background in finance and a career spanning public and private sector leadership, Rod brings a rare combination of technical insight, regulatory experience, and business acumen to an issue most would rather ignore.

For decades, the nuclear industry has lacked a permanent solution for high-level waste, relying instead on short-term storage and costly, politically stalled mined repository concepts. Deep Isolation offers a radically different approach: leveraging proven directional drilling technology from oil and gas to safely and affordably isolate nuclear waste more than a mile underground, horizontally, in stable geologic formations.

Rod breaks down:

• Why traditional mined repositories are 70% more expensive and far slower to implement
• How horizontal boreholes can isolate waste for over a million years with peak doses lower than a single banana per year
• What Deep Isolation’s universal canister makes possible across fuel types, reprocessing, and storage
• Why the real bottleneck isn’t technology, but outdated U.S. policy stuck on Yucca Mountain
• How countries like Estonia and others in Eastern Europe are leapfrogging the U.S. with forward-looking nuclear strategies

This episode also tackles widespread myths, including the “green goo” misconception, and explains why transportation concerns persist, even though nuclear waste has an extraordinary safety record.

Rod shares why the nuclear industry can’t afford to treat waste as an afterthought any longer, and why solving it now is essential to ensuring nuclear’s role in a clean energy future.

If you're curious about the back end of the nuclear lifecycle and how it may be the unlock for scaling next-gen clean power, this conversation delivers both a reality check and a hopeful vision for what's possible.
