    #266 Can the Grid Survive Climate Change?

    JOIN US FOR THE HACK SUMMIT! The HackSummit returns to Newlab on December 10-11, bringing together 500 founders, funders, and industry leaders in Climate Deep Tech. Together we’ll explore abundance, alongside Founders and Investors at Andreessen Horowitz, Brimstone, Crux, DCVC, Durin, Earth AI, Endolith, Navier, Radical AI, Rainmaker, Voyager Ventures and SOSV. Sign up for 10% off here. Hey everyone, welcome back to CleanTechies! Today, we’re diving into one of the most overlooked but fast-growing parts of climate tech right now: grid resilience. When we think about the clean energy transition, most of the attention goes to building more solar, more batteries, more generation. But what about protecting the systems we already have from extreme weather? That’s where Rhizome comes in. My guest today, Mishal Thadani, is the Co-Founder and CEO of Rhizome, a climate resilience software company helping utilities prepare for the future. Their platform helps grid planners and operators assess vulnerabilities, model investment scenarios, and understand how climate change will hit their systems over time. In simple terms: they’re helping utilities figure out where to spend every dollar smarter so they can keep the lights on when the next hurricane, wildfire, or heatwave hits. We dig into: How Rhizome turns weather data, climate projections, and utility failure history into real, actionable investment maps Why insurers and credit agencies are pushing utilities to start taking climate risk seriously The behind-the-scenes of selling into utilities — and why a 6–12 month sales cycle isn’t for the faint of heart How Mishal’s background in engineering and regulatory strategy shaped Rhizome’s design from day one How rising energy prices and the AI data center boom are reshaping utility priorities, putting a new spotlight on affordable solutions like energy efficiency and demand response. And here’s what I love best about this conversation: Mish shows how the climate tech space is expanding, showing adaptation and resilience. If you’re building in climate tech, especially in data, software, or infrastructure, this episode will give you a front-row seat into where the next wave of opportunity is. P.S. We’ve got a big announcement coming this quarter, stay tuned and keep listening so you don’t miss it. This is a public episode.

    #265 What is the EU Innovation Fund and Who Can Apply for Funding | Joel Armin-Hoiland (Climate Finance Solutions)

    JOIN US FOR THE HACK SUMMIT! The HackSummit returns to Newlab on December 10-11, bringing together 500 founders, funders, and industry leaders in Climate Deep Tech. Together we’ll explore abundance, alongside Founders and Investors at Andreessen Horowitz, Brimstone, Crux, DCVC, Durin, Earth AI, Endolith, Navier, Radical AI, Rainmaker, Voyager Ventures and SOSV. Sign up for 10% off here. Hey everyone, welcome back to CleanTechies! Today, we’re diving into one of the biggest non-dilutive funding opportunities out there: the EU Innovation Fund. We’re talking about €40 billion euros being deployed between now and 2030 to scale up the world’s most promising low-carbon technologies… and the crazy part? Only a fraction of it has been spent. To break it all down, I’m joined by Joel Armin-Hoiland, Founder and CEO of Climate Finance Solutions, and the go-to expert on non-dilutive funding. You might remember Joel from Episode 258, where we unpacked critical minerals funding from the DOE, and now he’s back to take us global. In this episode, Joel explains how the EU Innovation Fund is fueling deployment-ready tech (think steel, cement, hydrogen, CCUS, renewables, and energy storage) and how founders can actually win a slice of that €40 billion. We talked about several things such as the €5.5 billion call expected to drop this December and why the EU is favoring commercial-scale over early R&D. Plus Joel’s insider advice on how to phrase your applications because yes, reviewers are literally searching for keywords Since 2020,CCUSJoel and his team have already helped raise over $1.6 billion with a 90% success rate, so if you’re serious about securing non-dilutive capital, this is a must-listen. Tune in today because this funding window is opening fast, and the founders who prepare well are the ones who’ll win big later. This is a public episode.

    #264 Climate Week 2025 Recap | Silas Mahner (Cleantechies Podcast)

    JOIN US FOR THE HACK SUMMIT! The HackSummit returns to Newlab on December 10-11, bringing together 500 founders, funders, and industry leaders in Climate Deep Tech. Together we’ll explore abundance, alongside Founders and Investors at Andreessen Horowitz, Brimstone, Crux, DCVC, Durin, Earth AI, Endolith, Navier, Radical AI, Rainmaker, Voyager Ventures and SOSV. Sign up for 10% off here. Silas here! 👋 Before we jump into today’s episode, quick shoutout to Goodwin Law, CSC Leasing, and ErthTech Talent, the backbone behind our CleanTechies Live Podcast at Climate Week. (If you haven’t listened to that yet, check it out first — I’ll be referencing it a lot in this recap.) Quick plug: We also caught a bunch of raw takes from founders and investors between panels and events through candid man on the street interviews you’ll definitely want to see. I’ve finally had some time to process New York Climate Week. This solo episode is part recap, part reflection, but more importantly, it’s my honest take on where we are as a space and why I’m more bullish than ever on clean tech, and here are some of the things that stood out: I’ve never seen founders and investors this locked in. Everyone there was focused, sharp, and hungry. It honestly felt different this year, like the movement finally grew up. Let me walk you through it. Over the past year-ish, people have been asking: “Is the hype gone?” “Will funding drying up?” “Is the climate space cooling off?” What I saw at Climate Week says the exact opposite. Now is the best time to build if you’re a founder. In this episode, I break it down into a few key reasons, but before you dive in, chew on this: “When things get harder, only the best founders stay at the party.” The hype-cycle might be over, but that’s because we’re entering a much more mature version of the movement.
