The Green Blueprint

This week, we’re presenting a drop-in episode of Critical Capital, a new partner podcast from Crux and Latitude Studios.

The rush to build data centers has sparked an energy debate: will gas meet the growing demand or will clean firm power like nuclear step in? Nuclear has bipartisan support, new contracts from tech companies, and the capital to build. What it needs, according to Lara Pierpoint, is to be built on time and on budget with government support that lasts.

In this episode, Alfred Johnson sits down with Lara Pierpoint, managing director of Trellis Climate at Prime Coalition and a nuclear engineer by training, to talk about what it will take to build clean power for the data center era.

Together, they dig into whether nuclear can get out of its own way on costs, why data centers now draw the local opposition that nuclear once did, and what AI means for the security of the grid. They also cover what hyperscalers will pay for and how to make government funding promises last from one administration to the next.

While living in Delhi, Sorin Grama gave a window air conditioner to an employee. He found out weeks later she wasn't using it because the electricity costs were too high. It was a stark reminder that access to global cooling isn't about upfront equipment costs. It’s about the high electricity costs needed to run air conditioners.

To slash those costs, Sorin co-founded Transaera. His team deployed metal-organic frameworks (MOFs), which are highly engineered crystalline structures that act like super-desiccants. By capturing water molecules and drying the air before it is cooled, Transaera bypasses the massive energy costs of refrigerating airborne moisture.

The startup initially planned to build residential units for emerging markets, but then they got a nibble from Amazon. They pivoted away from residential efforts to integrate their MOF materials into larger commercial units. By partnering with an existing US manufacturer, they went from CAD drawings to a pilot unit on a rooftop in Houston in less than six months. That successful pilot ultimately led to a commercial agreement with Amazon.

So could this be the beginning of the end for conventional air conditioning?

When David Fauvre and his co-founder entered the battery space in 2015, they started as brokers exporting American battery waste to recycling partners in Korea and Japan. But as the industry grew, shipping companies increasingly refused to transport the hazardous materials, making it clear that the U.S. desperately needed its own domestic processing capabilities.

Rather than attempting to build a fully integrated, end-to-end "closed loop" recycling system—an incredibly complex and capital-intensive endeavor—Blue Whale Materials is focusing on doing one thing exceptionally well: pre-processing. Using a specialized thermal system to burn off impurities, the company liberates critical minerals like cobalt, nickel, and lithium from battery foils to create a highly concentrated product they’ve trademarked as “Black Sand.” This premium material is designed to seamlessly integrate into the supply chains of downstream refiners.

After proving their technology with a demonstration plant in Japan, Blue Whale secured private equity funding and recently commissioned its first full-scale commercial facility in Bartlesville, Oklahoma.

In this episode, host Lara Pierpoint talks with David about the capital-intensive reality of building industrial infrastructure outside the venture capital ecosystem, how an outdoor battery fire at their facility forced a major overhaul of their emergency response protocols, and how a $110 million expansion project backed by the Department of Energy is accelerating their roadmap.

“Good fires" naturally regenerate forests. But a rise in high-severity blazes in the American West are leaving behind barren moonscapes filled with dead trees. These scorched trees act as hazardous fuel for future fires, but clearing them to replant the landscape is astronomically expensive. Add to that a massive shortage in the conifer seed supply chain, and land managers simply don't have the resources to regenerate these forests on their own.

Grant Canary, CEO and founder of Mast Reforestation, is changing that.

Today, Mast Reforestation tackles the ultimate financial bottleneck by burying fire-killed trees deep underground in oxygen-free clay vaults. This permanently stores the timber's carbon, generating high-quality credits that pay for the expensive work of clearing the land and hand-planting new, fire-resilient forests.

In this episode, host Lara Pierpoint talks with Grant about the realities of shutting down a beloved hardware project, the financial arbitrage of buying a legacy seed bank, and how founders should make the case for dramatic startup pivots to their investors.

To build the physical infrastructure of the clean energy transition — from wind turbines and grid stabilization to massive new AI data centers — the world needs more copper between now and 2050 than humanity has produced in its entire history. But new copper mines take anywhere from 10 to 16 years to permit and build, meaning we’re not on track to meet our rapidly growing demand.

Liz Dennett, CEO and founder of Endolith, thinks the solution lies in material that has already been pulled from the earth. Endolith uses naturally occurring microbial communities, paired with real-time data, to extract more copper from low-grade ore at existing heap leaches. By bringing a mobile bio-rig directly to mine sites, Endolith continuously adds optimized microbes into existing sulfuric acid irrigation lines, essentially turning decades-old, multi-billion-dollar assets into precision engineering tools without disrupting downstream operations.

In this episode, host Lara Pierpoint talks with Liz about why the climate tech bias against biological approaches needs updating, how to navigate the notoriously risk-averse nature of the mining industry, and why she deliberately kept corporate venture capital (CVC) off her cap table to preserve the company's optionality.
