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

Fresh water is becoming one of the most valuable resources on a warming planet. This episode drills into how one startup, Source Global, has developed hydropanels that pull water vapor from the air using only sunlight. Lucas and Luna break down the technology—a hygroscopic material that absorbs moisture overnight, then uses solar heat to release it as liquid water—and the economics: the panels cost around $2,000 each and can produce up to five liters of water per day. They discuss where this works best (arid but humid places like the UAE and parts of India), why desalination and trucking water are still cheaper at scale, and who is actually buying these things: schools, hospitals, and off-grid communities. A concrete look at a technology that sounds like science fiction but is already deployed in over 50 countries.

Carbon offsets have a trust problem: buyers pay for credits, but how do they know the trees are still standing? In this episode, Lucas and Luna explore how one startup uses satellite imagery and machine learning to verify carbon projects in real time. They unpack the scale of the voluntary carbon market — a two-billion-dollar market growing at over 20 percent annually — and how AI can spot over-crediting and land-use changes that human auditors miss. The hosts also examine a case study from a mangrove restoration project in Indonesia where AI analysis revealed 30 percent less carbon storage than claimed. Plus: why this matters for net-zero pledges and how buyers can use data to avoid greenwashing. A focused look at the intersection of climate tech and financial accountability.

Lucas and Luna dive into the emerging market for blue carbon credits, focusing on mangrove restoration as a nature-based climate solution. They explore how projects in Indonesia and Kenya are generating verified carbon offsets, why blue carbon is valued higher than forestry credits, and the challenges of measuring and monetizing coastal ecosystem restoration. The episode examines the economics, verification standards, and scalability of this approach, including the role of startups like InPlanet and the Verra methodology for tidal wetlands. A concrete look at how mangroves are being turned into financial assets for climate and community.

Lucas and Luna explore why a growing number of property developers and cities are mandating all-electric buildings instead of buying offsets. They walk through a specific case: a 12-story mixed-use building in Denver that chose heat pumps, induction stoves, and battery storage over gas connections — and saved $700,000 in upfront utility costs. They discuss how the Inflation Reduction Act's rebates tip the economics, why the gas industry is fighting back with 'cooking freedom' messaging, and whether the electric grid can handle the load. A sharp look at one of the most consequential — and under-covered — climate policy shifts happening right now.

Episode 92 of The Climate Tech Podcast dives into a surprising climate solution: enhanced rock weathering. Lucas and Luna explore how a Canadian startup called Carbin Minerals is taking mining tailings—waste rock from copper and nickel mines—and accelerating their natural ability to absorb CO2 from the atmosphere. The episode centers on a single mine in British Columbia where the company has deployed its technology, capturing an estimated 1,000 tons of CO2 per year from just one site. Lucas explains the chemistry behind how crushed silicate minerals like olivine and basalt react with atmospheric carbon dioxide to form stable carbonates, locking carbon away for millennia. Luna questions the scalability challenges, including the massive amount of rock needed and the energy costs of grinding it. The hosts also touch on the economics: Carbin Minerals sells carbon removal credits to companies like Shopify and Stripe at around $600 per ton. The episode closes with a look at the global potential—if the world's 3,500 active mines adopted similar technology, enhanced weathering could sequester up to 2 billion tons of CO2 annually, roughly 5% of current global emissions.

Lucas and Luna dive into the world of methane pyrolysis, focusing on a startup that captures methane from landfills and converts it into hydrogen and solid carbon — avoiding CO2 emissions entirely. They walk through the technology, the economics, and why this approach could complement green and blue hydrogen. Specific numbers include the startup's pilot plant producing 1.5 tons of hydrogen per day and the cost target of under $2 per kilogram by 2027. A concrete look at a promising decarbonization pathway that also tackles methane, a potent greenhouse gas.

In this episode of The Climate Tech Podcast, Lucas and Luna explore a surprising source of renewable fuel: the spent coffee grounds from your morning espresso. They dive into the story of Bio-bean, a UK startup that collects coffee waste from cafes and office buildings and turns it into a biodiesel blend that powers London's double-decker buses. Lucas explains the chemistry—how oil is extracted from the grounds and processed into a B20 fuel—and breaks down the numbers: one cup of coffee generates enough grounds to produce a measurable fraction of a mile of bus travel, and at scale, the company processes 50,000 tons of grounds annually, saving the equivalent of 6.5 million tons of CO2. Luna questions the scalability and cost versus conventional biodiesel, and they discuss the logistics of collecting a wet, heavy waste stream from thousands of locations. The conversation touches on the circular economy, waste-to-energy policy in the UK, and whether coffee-biofuel is a niche solution or a model for other urban waste streams. A concrete, eye-opening look at decarbonizing transportation with something you probably threw away this morning.

Methane from livestock manure is 80 times more potent than CO2 over 20 years. But instead of letting it escape into the atmosphere, a growing number of dairy farms are capturing it and upgrading it into pipeline-grade renewable natural gas, or RNG. In this episode, Lucas and Luna dive into the story of Brightmark, a startup that builds anaerobic digesters on large dairy farms, turning a pollution problem into a revenue stream. They walk through the economics: how a single digester can generate $3-5 million in annual revenue from RNG sales, plus additional income from renewable fuel credits under the federal Renewable Fuel Standard and California's Low Carbon Fuel Standard. They also explore the tensions — critics argue that large digesters incentivize factory farming and methane leakage is hard to monitor. By the end, you'll understand why RNG is the fastest-growing segment of the US renewable energy market and whether it's a genuine climate solution or a fossil-fuel-adjacent band-aid.

Seasonal thermal energy storage could reshape how we heat buildings. Lucas and Luna dig into Polar Night Energy, a Finnish startup that builds giant sand batteries — silos of heated sand that store solar and wind heat from summer for use in winter. They explore the physics of thermal storage at grid scale, the cost advantage over lithium-ion for heat, and the real-world test in a small Finnish town where a 100-metric-ton sand battery now powers a district heating system. The conversation covers the technology's round-trip efficiency, the role of insulated steel silos, and why industrial waste heat could be the next frontier. Plus, a practical look at where thermal storage works best — from cold climates to data center campuses — and the economic crossover point for replacing natural gas boilers.

Episode 87 of The Climate Tech Podcast dives into a surprising climate solution: feeding livestock methane-derived protein. Lucas and Luna explore the startup Calysta, which uses natural gas fermentation to produce FeedKind — a protein powder that replaces soy and fishmeal. They break down the numbers: soy farming drives deforestation and emits roughly 250 million metric tons of CO2 annually, while Calysta's process reduces land use by 99% and water use by 90%. The hosts discuss the technology behind methanotrophs (bacteria that eat methane), the role of companies like Cargill and ADM in scaling production, and the tricky question of whether feeding cows gas-derived protein is actually 'natural.' The episode lands on a key tension: methane is a potent greenhouse gas, but capturing it for feed could create a powerful carbon-negative loop. Tune in for a deep dive into the intersection of industrial biotech, livestock sustainability, and the future of protein.
