Bryan Hassin: There Is No Energy Transition Without a Materials 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 growthHow AI data centers add another layer of pressure to materials demandWhy mining and recycling more copper may help, but may not solve the full problemHow Galvorn is made and why carbon nanotube alignment is the key breakthroughWhere Galvorn can compete with copper today and where copper still has advantagesWhy conductivity must be evaluated alongside weight, heat, strength, frequency, and system designHow wet fiber spinning could help advanced carbon materials scale economicallyThe qualification hurdles behind aerospace, defense, medical, grid, and wire-and-cable adoptionWhy hard-tech commercialization requires manufacturers, investors, policymakers, and customers to move togetherWhat investors often misunderstand about materials startupsHow entirely new materials can unlock designs that were previously impossibleBryan 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.Links: Bryan Hassin on LinkedInDexMat's WebsiteInfo on GalvornWes Ashworth: https://www.linkedin.com/in/weslgs/Email: [email protected]://leegroupsearch.com/green-giants-podcast/https://leegroupsearch.com/
