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

Episode 86 of The Climate Tech Podcast. Lucas and Luna look at ground-source heat pumps — a decades-old technology that's suddenly cost-competitive thanks to a new generation of compact drilling rigs and federal tax credits. They focus on Dandelion Energy, a startup spun out of Google's parent company Alphabet, which has drilled over 4,000 residential geothermal systems in the Northeast U.S. The hosts explain how the tech works (a loop of water underground, stable 55-degree earth temperature, no outdoor condenser unit), why the upfront cost is still the main hurdle (around $18,000 after the 30 percent federal tax credit), and how Dandelion's proprietary drilling rig cut installation time from two weeks to two days. They also touch on the Inflation Reduction Act's expanded incentives and the looming challenge of finding enough trained drillers as the market heats up. A sharp, grounded look at one of the most capital-efficient climate solutions most homeowners have never considered.

Steelmaking accounts for roughly 7 percent of global carbon emissions, and the conventional blast furnace process is notoriously hard to clean up. In this episode, Lucas and Luna explore how green hydrogen is beginning to replace coke as the reducing agent in steel production, with a focus on the HYBRIT project in Sweden and the startup H2 Green Steel. They break down the chemistry, the economics, and the timeline: the first fossil-free steel was delivered to Volvo in 2021, and commercial-scale production is expected by 2026. They also discuss the challenge of scaling green hydrogen production, the need for massive electrolyzer capacity, and what this means for steel buyers and investors. A deep dive into one of the hardest-to-abate sectors in the industrial economy.

In this episode, Lucas and Luna dig into the emerging industry of vermicomposting at scale — using earthworms to process agricultural waste into high-quality organic fertilizer. They profile a California-based startup, Worm Power Inc., that processes 50,000 tons of dairy manure annually and sells its castings at a premium to vineyards and organic farms. Lucas explains the market inefficiency: synthetic fertilizer prices have doubled since 2021 due to natural gas volatility, while worm castings offer a stable, nutrient-rich alternative with a carbon-negative footprint. Luna questions the scaling challenges: worm biology is sensitive to temperature, moisture, and heavy metals. They also discuss competing approaches like black soldier fly larvae and thermal composting. The episode closes with a look at regulatory tailwinds from California's SB 1383, which mandates organic waste diversion.

Episode 82 of The Climate Tech Podcast explores how advanced software platforms are enabling real-time optimization of the electricity grid. Lucas and Luna dive into the specific case of startup 'GridAI' (a composite example), which uses machine learning to balance supply and demand across thousands of distributed energy resources like solar panels, batteries, and electric vehicle chargers. They discuss how the company achieved a 15% reduction in peak load for a midwestern utility in 2025, saving millions in infrastructure costs. The hosts also touch on the broader shift from hardware-centric to software-centric grid management, the role of virtual power plants, and why FERC Order 2222 is unlocking new revenue streams for aggregators. Listeners learn one concrete takeaway: software-defined flexibility is becoming as critical as physical generation capacity.

When Hurricane Ian hit Florida in 2022, Babcock Ranch — a town powered by a solar-plus-storage microgrid — never lost power while millions around it sat in the dark. In this episode, Lucas and Luna dig into the microgrid revolution, focusing on how a single Florida community became the proof-of-concept for resilient, decentralized energy. They break down the economics: Babcock Ranch's microgrid, built by Kitson & Partners and Florida Power & Light, combines 150 megawatts of solar with 10 megawatts of battery storage. It serves about 2,000 homes and a town center. The key number: the microgrid saved the town an estimated $5 million in avoided outage costs during just that one storm. Lucas explains why traditional utilities are starting to embrace microgrids — not just for resilience, but as a way to defer multibillion-dollar transmission upgrades. Luna asks who pays, whether this scales beyond wealthy enclaves, and what happens when the sun doesn't shine for three days straight. The hosts explore the real bottleneck: interconnection rules and utility cooperation. They close by asking whether every new real estate development should be built with a microgrid by default. This episode is a sharp, concrete look at one technology that's quietly reshaping how we think about power reliability.

Concrete is responsible for roughly 8 percent of global CO2 emissions — more than aviation and shipping combined. In this episode, Lucas and Luna explore how one startup is tackling that problem by recycling demolition waste into new concrete that actually absorbs carbon as it cures. They break down the chemistry behind carbon-negative aggregate, the economics of selling a material that costs more than conventional concrete, and why the company's first big contract — a 12-story office tower in Denver — could be a bellwether for the entire building industry. Lucas walks through the key patent that lets the startup mineralize CO2 into calcium carbonate at standard curing temperatures, and Luna asks whether the process scales beyond niche projects. They also look at how the Inflation Reduction Act's 45Q tax credit changes the unit economics, and why the biggest roadblock isn't technology but building code approval. If you're in construction, real estate, or climate tech, this episode makes a concrete case for why the built environment's emissions problem might have a surprisingly solid fix.

Episode 79 of The Climate Tech Podcast explores how a startup called Electrode leverages artificial intelligence to dynamically match wind farm output with hydrogen electrolyzers, solving the intermittency problem that has long plagued green hydrogen. Lucas and Luna dive into the technical details of how the AI predicts wind patterns hours ahead and adjusts electrolyzer load in real time, cutting hydrogen production costs by up to 30 percent. They discuss a pilot project in Texas where excess wind energy that would have been curtailed now powers 24/7 hydrogen production, and what this means for the broader decarbonization of industrial processes like steelmaking and ammonia production. The conversation also touches on the economics of grid-connected versus islanded electrolyzers, and why big oil companies are starting to partner with AI startups in the clean energy space.
