    The state of clean energy manufacturing | John Hensley, American Clean Power

    In this episode, Gil Jenkins and Guy Van Syckle speak with John Hensley, Senior Vice President – Markets and Policy Analysis for the American Clean Power Association (ACP). We dig into how clean energy manufacturing is powering a new chapter of economic prosperity, exploring the industry's rapid growth in facilities, the economic impact on communities, workforce development challenges, supply chain progress, the role of the 45X tax credit, and where the industry is headed by 2030.

    Renewable water and a >$1 trillion investment need | Guillaume Clairet, COO of H2O Innovation

    Water is something most of us take for granted. We turn on the tap, and it's just there. But behind that tap is an increasingly strained system that is quietly becoming one of the defining infrastructure challenges of our time. Just in the US, McKinsey estimates we are underinvesting in water assets by about $100 billion annually, with the cost only compounding as more investment is delayed.  The effects are already being seen with over 20% of treated water lost through leaks in pipes that are sometimes 70 years old, generating no revenue for cash-strapped utilities. The record data center and industrial development buoying our economy is now facing major opposition, often due to local water demands. In addition, there are growing concerns and regulations regarding the forever chemicals, known as PFAS, which are showing up in more of our water supply. Today, I'm joined by Guillaume Clairet of H20 Innovation, who has helped build the company into a water treatment powerhouse over the past 25 years. From massive municipal reuse projects to distributed systems serving the critical industrial facilities, H2O is leading the water infrastructure buildout and offers a hopeful outlook on how we can start addressing our water needs. Let's dive in. Links: H20 Innovation Website Guillaume Clairet’s LinkedIn Email your feedback to Gil, Guy, Hilary, and Kenny at climatepositive@hasi.com.

    Investing in nature’s most powerful ecosystems | Tripp Wall, CEO of Pantheon Regeneration

    In this episode of Climate Positive, Guy Van Syckle connects with Tripp Wall, CEO of Pantheon Regeneration, to explore how his team is turning degraded peatland ecosystems into high-impact stores of carbon with a wealth of additional benefits for biodiversity and resiliency. We dive deep into an unsung hero of carbon sequestration—peatlands—which cover just 3% of the earth's surface but store twice as much carbon as all the world's forests combined. Tripp explains the hydrological engineering and cutting-edge tech helping to restore and monitor these ancient ecosystems. We discuss the evolving Voluntary Carbon Market, the supply-demand mismatch approaching, and how nature-based solutions offer a highly scalable alternative to engineered carbon capture.  Additionally, Guy and Tripp explore how high-quality removal credits with biodiversity co-benefits are attracting major corporate offtakes, and the opportunities for traditional infrastructure investors to invest in natural capital to secure differentiated returns.

    Rethinking nuclear: from bespoke plants to mass manufacturing reactors | Matt Loszak, CEO of Aalo Atomics

    In this Climate Positive episode (our 100th!), Chad and Guy talk with Matt Loszak, CEO and co-founder of Aalo Atomics, about their innovative approach to building factory-made advanced micro reactors to power the AI-driven energy demand surge. Matt shares his unconventional journey from nuclear engineering student to software entrepreneur to nuclear startup founder, explaining why he believes we're entering a "second atomic age" for clean energy. Matt discusses Aalo's strategy of vertical integration and mass manufacturing, inspired by SpaceX and Tesla, to deliver compact, liquid metal-cooled nuclear reactors that can be deployed rapidly for data centers and other applications. He explains how the regulatory environment has evolved with recent executive orders streamlining pathways to criticality, the company's ambitious timeline to achieve zero power criticality by July 2026, and their vision for 3-cent-per-kilowatt-hour nuclear energy at scale. Matt also addresses public safety perceptions, the advantages of particular reactor technologies, and how their 50-megawatt "Aalo Pod" architecture provides the redundancy and incremental buildout that hyperscalers need.

    Turning homes into grid powerhouses | Vinnie Campo, CEO of Haven Energy

    In this episode of Climate Positive, Kenny Gayles talks with Vinnie Campo, CEO and co-founder of Haven Energy, about their unique batteries-as-a-service approach that reduces barriers to affordable, reliable backup power by integrating home storage into virtual power plants (VPPs) to support the electric grid.  Vinnie shares Haven’s journey as a rapidly growing operator of distributed energy assets. He discusses the effects of California’s policy impacts on battery adoption, the influence of electrification and AI-driven demand on utilities, and why batteries are vital for grid resilience. He also discusses regulatory and market trends transforming residential energy, and what it takes to scale integrated energy infrastructure solutions.  Links: Haven Website Vinnie Campo on LinkedIn Haven Blog: “Raising New Funds to Speed Distributed Power” LADWP Self-Generation Incentive Program (SGIP) Email your feedback to Gil, Guy, Hilary, and Kenny at climatepositive@hasi.com.

    What’s at stake for U.S. hydropower | Malcolm Woolf, CEO of NHA

    In this episode of Climate Positive, Gil Jenkins speaks with Malcolm Woolf, President and CEO of the National Hydropower Association (NHA). They discuss the current state of the U.S. hydropower industry, its role in providing carbon-free electricity, and the challenges and opportunities facing the sector. A central focus of the conversation is the hydropower relicensing process -- how it works, where projects can stall, and how lengthy reviews can delay investment, upgrades, and in some cases lead facilities to shut down. Malcolm shares real-world examples to illustrate what’s at stake, while also exploring the potential to add generation to non-powered dams, the role of pumped storage in supporting grid reliability, and emerging marine energy technologies.

    EV semi-trucks are here — how EV Realty is scaling the charging | Patrick Sullivan

    The trucking industry operates on razor-thin margins and highly optimized schedules. Think free delivery from click to your door in 4 hours. Decarbonizing that kind of industry requires more than green intentions—it requires a highly reliable solution that drives real economic value.  In the push to electrify large trucks, we often focus on the vehicles. But this rollout requires industrial-scale access to electricity in the context of an often-challenged distribution grid. My guest today is Patrick Sullivan, CEO of EV Realty.  Building on decades of renewable energy development experience, navigating electricity grid constraints, Patrick and team are enabling the EV semi-truck rollout today. We discuss the coming wave of EV trucks, the realities of the freight supply chain, and how EV Realty is building a network that works for the bottom line, local communities, and the broader climate.
