The Climate Tech Podcast with Fexingo: Energy, Sustainability, and Decarbonization Companies

Methane leaks from oil and gas wells are 80 times more potent than CO2 over 20 years. A small startup called Crusoe Energy is capturing that flared methane and using it to power mobile bitcoin mining containers. In this episode, Lucas and Luna break down the math: how a single gas flare that would have emitted 500,000 cubic feet of methane per day now powers 300 mining rigs, generating about 3.5 bitcoins per day. They explore the economics, the environmental trade-offs, and why critics argue it's still just enabling fossil fuel extraction. A concrete look at a controversial bridge technology.

Ammonia production accounts for nearly two percent of global carbon emissions. But a new wave of green hydrogen projects is changing that. In this episode, Lucas and Luna break down one specific project in Norway that aims to produce fossil-free ammonia by 2027 — and why existing infrastructure for fertilizer transport makes this a faster decarbonization play than hydrogen for steel or aviation. They walk through the numbers: how much electricity it takes, what the price gap looks like versus grey ammonia today, and who's already buying. A grounded look at industrial decarbonization where the economics might actually work.

Episode 114 of The Climate Tech Podcast dives into a surprising use for captured CO2: turning it into ink. Lucas and Luna explore how a California startup called Air Ink is recycling industrial carbon emissions into high-quality black pigment for printers, pens, and even commercial art. They walk through the chemistry — capturing CO2 from factory flues, converting it into carbon black, and blending it into ink — and the economics: why the process costs more than conventional petroleum-based carbon black but is starting to find buyers in packaging and publishing. They also compare it to other carbon utilization pathways and ask whether the market is big enough to matter at scale. A focused 10-minute look at one product proving that captured carbon doesn't have to stay buried.

In episode 113 of The Climate Tech Podcast, Lucas and Luna explore a surprising new source of low-carbon cement: mining tailings. They dig into the numbers behind Brimstone Energy, a startup that uses calcium silicate rock—leftover from gold and copper mining—to produce cement with near-zero process emissions. Lucas breaks down why cement accounts for roughly 8% of global CO2 emissions, and how Brimstone's process avoids the limestone calcination problem that plagues traditional manufacturing. Luna pushes back on cost scalability and whether mining waste supply is actually large enough to matter. They also touch on the role of carbon capture versus alternative chemistries, and why investors are pouring hundreds of millions into this space. Specific figures include: 600 million tons of mining tailings produced annually in the US alone, and Brimstone's claim of $100 per ton production cost—competitive with conventional cement. The episode closes with a forward-looking question about whether green cement can ever be cheap enough for developing-world infrastructure.

Lucas and Luna dive into the growing industry of renewable natural gas (RNG) from food waste, focusing on a specific case: a startup called WasteFuel that is building anaerobic digesters to turn organic waste from grocery stores and restaurants into pipeline-grade methane. They discuss the economics behind RNG, including the role of California's Low Carbon Fuel Standard credits, which can make RNG worth up to $70 per MMBtu compared to $3 for fossil gas. They also explore the challenge of feedstock supply and why some environmentalists are skeptical about methane leaks from digesters. By the end, you'll understand why RNG is attracting investment from oil majors like BP and why it's not a silver bullet for decarbonization.

When Hurricane Helene knocked out power across the Southeast in September 2024, one hospital in rural North Carolina never lost power—not for a second. That hospital runs on a microgrid: a self-contained energy system that can disconnect from the main grid and generate its own electricity using solar panels and battery storage. In this episode, Lucas and Luna explore how microgrids are moving from military bases and college campuses into critical community infrastructure. They focus on one case: a 2.5-megawatt microgrid at a hospital in Lumberton, North Carolina, which kept operating through a four-day blackout while the surrounding county went dark. Lucas explains how federal grants from the Department of Energy's Grid Resilience Program and the Inflation Reduction Act's Investment Tax Credit are driving adoption, with over 200 hospital microgrids now in development nationwide. Luna asks whether the economics pencil out for smaller facilities and whether the technology can scale beyond emergency backup. The episode closes with a look at the 'virtual power plant' model—where hundreds of microgrids could one day trade power with each other, creating a decentralized, self-healing grid.

Steel production accounts for roughly 8 percent of global carbon dioxide emissions, mostly because the traditional blast furnace burns coal to strip oxygen from iron ore. But a Swedish startup called Stegra (formerly H2 Green Steel) is pioneering a different route: using green hydrogen instead of coal to reduce iron ore to iron, with water vapor as the only byproduct. This episode dives into how Stegra raised over $7 billion in funding, built a gigawatt-scale electrolyzer plant in northern Sweden, and plans to deliver its first fossil-free steel to customers like Mercedes-Benz and Volvo by late 2026. Lucas and Luna discuss the technical challenges of scaling green hydrogen production, the economics of green steel vs. traditional steel, and whether this process can truly be cost-competitive without carbon taxes or subsidies.

Lucas and Luna dive into the emerging world of wave energy converters that power remote ocean sensors—eliminating the need for disposable batteries and costly maintenance. They focus on a specific startup, CalWave Power Technologies, which has been testing its xWave device off the coast of California since 2023. The episode explains how the device works, the economics of replacing lithium batteries in buoys used for climate monitoring, and why the Department of Energy's 2024 prize spurred innovation. Lucas breaks down the levelized cost of energy for wave power versus solar-plus-battery for offshore applications, and Luna questions whether the technology can scale beyond niche sensor markets. The conversation explores the intersection of marine robotics, climate data, and renewable energy, offering listeners a concrete takeaway: wave power could cut the cost of ocean monitoring by up to 40 percent within five years.

Data centers need round-the-clock clean power, and geothermal is stepping up. Lucas explains how companies like Fervo Energy and Project Red are using fracking techniques from oil and gas to drill deep geothermal wells that can produce 24/7 baseload electricity. Luna asks whether the costs pencil out versus solar-plus-storage. We look at the DOE's Enhanced Geothermal Shot target of $45 per megawatt-hour by 2035, and why tech giants like Google and Microsoft are signing power purchase agreements for geothermal. A concrete look at how an old energy source is getting a high-tech reboot.

In Episode 107 of The Climate Tech Podcast, Lucas and Luna explore the economics of vertical farming — specifically how one startup, Aerofarms, has cracked the unit economics of growing leafy greens indoors without soil. They break down the numbers: how Aerofarms reduced energy costs by 40 percent using proprietary LED spectra and closed-loop water systems, why their New Jersey facility produces 2 million pounds of greens per year on just one acre of vertical space, and how they achieved a 90 percent reduction in water usage compared to field farming. The hosts also discuss the pivot from expensive berries to high-volume greens that grocery chains actually want, and why vertical farming is still a tough bet without cheap renewable energy. A candid look at what it really takes to make indoor agriculture work as a business.
