  • How One Startup Turns Methane Ice Into Transport Fuel

    How One Startup Turns Methane Ice Into Transport Fuel
    2026/06/07
    Methane hydrates — ice-like crystals on the ocean floor — hold more energy than all known fossil fuels combined. But they've been notoriously difficult to extract without triggering massive methane release. This episode profiles a Colorado-based startup called HydraShift that has developed a novel 'solid-to-gas-to-liquid' process to harvest methane from submarine hydrates and convert it directly into drop-in shipping fuel. Co-founder Dr. Elena Voss explains how her team's catalyst bed can process 200 tons of hydrate per day on a single offshore platform, producing fuel with negative carbon intensity because the methane would have leaked anyway. We discuss the $80 million Series B they closed in March, the regulatory hurdles from the International Seabed Authority, and why environmental groups are split — some seeing this as a bridge fuel, others as a license to drill. Lucas and Luna also dive into the economics: at $2.80 per gallon equivalent, HydraShift claims it can undercut conventional bunker fuel without subsidies. A concrete look at one of the most controversial frontier technologies in climate tech. #MethaneHydrates #HydraShift #DrElenaVoss #ShippingFuel #CleanTech #CarbonNegative #SeriesB #InternationalSeabedAuthority #OceanMining #BridgeFuel #ClimateTech #Business #Technology #FexingoBusiness #BusinessPodcast #Decarbonization #EnergyTransition #SubmarineResources Keep every episode free: buymeacoffee.com/fexingo

  • How One Startup Turns Pig Manure Into Jet Fuel

    How One Startup Turns Pig Manure Into Jet Fuel
    2026/06/07
    Episode 35 of The Climate Tech Podcast looks at a surprising feedstock for sustainable aviation fuel: livestock manure. Lucas and Luna explore how a Nebraska-based startup called FarmFuel Energy is building its first commercial plant to convert hog waste into drop-in jet fuel, potentially cutting emissions by 80% compared to fossil kerosene. They break down the two-step process — anaerobic digestion followed by Fischer-Tropsch synthesis — and the economics of a facility that costs $120 million to build but can produce 10 million gallons of fuel per year. They also discuss the regulatory push from the EPA's Renewable Fuel Standard and the Inflation Reduction Act's sustainable aviation fuel tax credit, which together make manure-to-fuel projects viable. But challenges remain: scaling the feedstock supply chain, competing with corn ethanol for waste streams, and the sheer volume of manure needed. By the end, listeners will understand why pigs might just help decarbonize aviation. #SustainableAviationFuel #PigManure #FarmFuelEnergy #ClimateTech #Decarbonization #FischerTropsch #AnaerobicDigestion #RenewableFuelStandard #InflationReductionAct #JetFuel #Agriculture #WasteToEnergy #EmissionsReduction #Biofuels #Nebraska #Startup #Business #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo

  • How a Startup Turns Methane from Landfills into Graphene

    How a Startup Turns Methane from Landfills into Graphene
    2026/06/06
    Lucas and Luna explore a startup called NanoCarbon that uses a plasma reactor to convert methane from landfills into graphene and clean hydrogen. Graphene is a super-strong, conductive material used in batteries, concrete, and coatings. The process is also carbon-negative because it prevents methane, a potent greenhouse gas, from escaping into the atmosphere. The hosts discuss the technology, the economics, and why this could be a scalable solution for both waste management and advanced materials. This episode dives into the science, the business model, and the potential impact of turning a climate problem into a valuable product. #NanoCarbon #Graphene #MethaneCapture #LandfillGas #PlasmaReactor #CleanHydrogen #CarbonNegative #AdvancedMaterials #ClimateTech #WasteToValue #Decarbonization #Startup #Sustainability #Business #Technology #FexingoBusiness #BusinessPodcast #ClimateTechPodcast Keep every episode free: buymeacoffee.com/fexingo

    How a Startup Turns Methane from Landfills into Graphene
    2026/06/06
    In this episode, Lucas and Luna explore how one startup is taking methane gas from landfills and turning it into graphene, a material stronger than steel and more conductive than copper. The company, called Graphene Innovations Ltd, uses a plasma reactor to crack methane molecules into hydrogen and carbon atoms, assembling them into graphene sheets. They discuss the economics: the cost of capturing methane versus the value of the graphene produced, which can sell for up to $100 per kilogram. Lucas breaks down how this process can actually generate carbon-negative credits, since methane is 80 times more potent than CO2 as a greenhouse gas. Luna asks about the scalability and whether the graphene market is ready for this supply. They also touch on the broader implications for waste management and industrial decarbonization. A focused look at how a potent pollutant becomes a high-value material. #Graphene #MethaneCapture #LandfillGas #CarbonNegative #PlasmaReactor #Decarbonization #ClimateTech #WasteToValue #Nanomaterials #CarbonCredits #IndustrialDecarbonization #Business #Technology #Startup #Innovation #Sustainability #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How One Startup Turns Excess Wind Into Green Hydrogen

    How One Startup Turns Excess Wind Into Green Hydrogen
    2026/06/05
    Episode 32 of The Climate Tech Podcast takes you inside a Danish startup that's solving one of renewable energy's biggest headaches: what to do with all that excess wind power. When the wind blows harder than the grid can handle, turbines are often shut down — a waste of clean electricity. But this company, ElectroPower, has built a modular electrolyzer that turns that cheap, abundant power into green hydrogen, which can be stored, shipped, or burned as fuel. Lucas and Luna walk through the numbers: how a single 10-megawatt unit can produce 1,500 kilograms of hydrogen per day, and how the economics work when the electricity is essentially free. They also discuss the pilot project in Western Jutland, where a cluster of 20 turbines now feed directly into an on-site hydrogen plant, and what that means for grid stability and the future of industrial decarbonization. If you've ever wondered when green hydrogen stops being a futuristic promise and starts being a real business, this episode gives you a concrete answer. #GreenHydrogen #ElectroPower #WindEnergy #ExcessPower #Electrolyzer #GridStability #Denmark #Decarbonization #ClimateTech #RenewableEnergy #IndustrialDecarbonization #EnergyStorage #Business #Technology #FexingoBusiness #BusinessPodcast #LucasAndLuna #TheClimateTechPodcast Keep every episode free: buymeacoffee.com/fexingo

  • The Startup That Turns Industrial Heat Into Clean Electricity

    The Startup That Turns Industrial Heat Into Clean Electricity
    2026/06/05
    Episode 31 of The Climate Tech Podcast dives into a lesser-known frontier of decarbonization: industrial waste heat recovery. Lucas and Luna explore how one startup, Thermonics Energy, is using solid-state thermoelectric generators to capture ultra-high-temperature exhaust from steel mills, glass furnaces, and cement kilns — converting it directly into electricity without any moving parts. They break down the physics of the Seebeck effect, the challenge of material costs (bismuth telluride vs. new half-Heusler alloys), and the economics at scale: a single steel mill can generate 5-8 megawatts of additional power from waste heat, cutting its electricity bill by $3-4 million a year. The hosts also discuss why this technology has been stuck in the lab for decades and what's finally changing — including DOE grants, rising industrial electricity prices, and a modular design that lowers installation risk. A concrete, numbers-driven look at an overlooked piece of the energy puzzle. #ClimateTech #IndustrialDecarbonization #WasteHeatRecovery #Thermoelectrics #ThermonicsEnergy #CleanEnergy #EnergyEfficiency #SolidState #SeebeckEffect #SteelIndustry #CementKilns #Manufacturing #Sustainability #Renewables #Business #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • The Startup That Turns Plastic Bottles Into Desalination Membranes

    The Startup That Turns Plastic Bottles Into Desalination Membranes
    2026/06/04
    On this episode of The Climate Tech Podcast, Lucas and Luna explore how a Boston-based startup, AquaCycle, developed a new reverse osmosis membrane made entirely from recycled PET plastic. The company's breakthrough could cut the cost of seawater desalination by 30 percent while diverting millions of plastic bottles from landfills. Lucas breaks down the chemistry, the economics, and the scalability challenge: can a membrane made from bottle flakes hold up under years of high-pressure operation? Luna pushes back on whether recycled materials can meet the purity standards required for drinking water. The conversation touches on the hidden carbon footprint of traditional membrane manufacturing, the startup's pilot plant in San Diego, and why the biggest investor in this technology is a beer company that needs ultra-pure water for brewing. #AquaCycle #Desalination #ReverseOsmosis #RecycledPlastic #PET #WaterTech #ClimateTech #MembraneTechnology #SeawaterDesalination #CircularEconomy #PlasticWaste #CleanWater #Sustainability #SanDiegoPilot #BrewingIndustry #Business #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How One Startup Turns Coffee Grounds Into Biofuel for Buses

    How One Startup Turns Coffee Grounds Into Biofuel for Buses
    2026/06/04
    Lucas and Luna explore the unlikely journey of coffee waste to bus fuel. A startup in London has figured out how to collect used coffee grounds from cafes and turn them into a biodiesel blend that powers city buses. They break down the numbers: each tonne of grounds yields about 200 liters of oil, and the company is already processing over 5,000 tonnes a year. Lucas questions whether the math scales beyond a niche, and Luna pushes back with data on global coffee waste volumes. It's a concrete look at one of the more surprising corners of the biofuel world — and a reminder that feedstock innovation matters as much as engine technology. #CoffeeGrounds #Biofuel #WasteToFuel #Biodiesel #London #CircularEconomy #Decarbonization #SustainableTransport #Feedstock #Startup #Business #Technology #ClimateTech #EnergyTransition #FexingoBusiness #BusinessPodcast #ClimateTechPodcast #LucasAndLuna Keep every episode free: buymeacoffee.com/fexingo
