Eugene Beh is the founder of Quino Energy, where he’s commercializing organic flow batteries that are safer, cheaper, and more scalable than their vanadium and lithium-ion cousins. With a background in physics and chemistry from Harvard and Stanford, Eugene has traded academic labs for chemical plants—and he’s betting that petroleum byproducts might just be the unlikely hero of long-duration energy storage.

In this episode we talked about:

 🔋 Why Quino's aqueous organic flow batteries don’t catch fire, unlike lithium-ion
 💰 How Eugene expects his electrolytes to undercut vanadium on cost—possibly this year
 🏗️ Why reusing tank infrastructure could slash battery installation costs
 🌍 What makes Quino’s batteries geopolitically boring, and why that’s a good thing
 🏥 Why hospitals, factories, and AI-fueled data centers might be early adopters
 🛢️ And how coal tar and clothing dye might save us from an electrified future dominated by flammable batteries

Jannik De Winter is an investor at PT1, a Berlin-based VC focused on greening the built environment. He recently co-authored a white paper on adaptation tech—the technologies we’ll need now that we’ve officially blown past 1.5°C. We talked about why climate resilience is an investment opportunity, not just a government expense, and why adaptation tech is still so poorly defined.

We touched on:

🔥 How climate adaptation tech is more than just seawalls and sandbags—it includes urban cooling, climate risk modeling, and even giving EV batteries a second life
💰 The trillion-dollar adaptation funding gap and why most of it isn’t coming from the private sector (yet)
🌍 Why Europe, and especially Germany, is ahead on adaptation policy, and what that means for startups and investors
🚰 The wild inefficiencies in water infrastructure—40% of Italy’s piped water just disappears—and the startups trying to fix it
🛰️ AI-powered disaster detection, from wildfire monitoring via satellite to real-time flood tracking
🎙️ PT1’s upcoming event on adaptation tech in Berlin, plus their podcast series diving into specific adaptation challenges
