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

Episode 126 explores the rise of virtual power plants (VPPs) — networks of distributed energy resources like home batteries, smart thermostats, and electric vehicle chargers that utilities can dispatch to balance the grid. Lucas breaks down how Tesla's Autobidder platform and Sunrun's partnership with PG&E are turning thousands of small devices into a single, controllable resource. He explains the economics: VPPs can cost 40-60% less than building a new natural gas peaker plant, and they're already operating in California, Texas, and parts of Europe. Luna questions the regulatory hurdles and whether consumers really sign up in large numbers. The hosts also touch on a recent rulemaking at FERC that could open wholesale markets to aggregated distributed resources. This episode is for anyone who owns a smart thermostat or is considering a home battery and wonders how those devices might earn money while helping keep the lights on.

Concrete production accounts for roughly 8 percent of global CO2 emissions — more than aviation and shipping combined. In this episode, Lucas and Luna explore how a new wave of startups is rethinking the world's most-used building material. They focus on one company in particular: Sublime Systems, a Massachusetts-based startup that has developed an electrochemical process to make cement at room temperature, entirely eliminating the need for fossil-fuel-fired kilns. Lucas breaks down the chemistry — traditional cement relies on heating limestone to 1,450 degrees Celsius, which releases CO2 both from the fuel and the limestone itself — and explains how Sublime's process sidesteps both sources. Luna digs into the economics: can a zero-emission cement compete on price with the legacy industry, which benefits from decades of scale and subsidized energy? The episode also touches on the regulatory tailwinds from the Inflation Reduction Act and the growing demand from tech companies and governments for low-carbon construction materials. By the end, listeners will understand why concrete decarbonization is both technically hard and commercially urgent — and why investors are betting big on solutions that don't require carbon capture retrofits.

Episode 124 takes you inside the recent wave of major oil-and-gas companies investing in direct air capture (DAC) technology. Lucas and Luna break down why Occidental Petroleum, Chevron, and others are pouring hundreds of millions into pulling CO2 from the atmosphere — even as they continue drilling. They examine the economics: how the 45Q tax credit makes DAC viable at $180 per ton, the role of carbon removal credits in voluntary markets, and whether this is genuine decarbonization or a strategic hedge. The episode focuses on Occidental's planned 'Stratos' DAC plant in Texas, which will capture 500,000 tons of CO2 annually by 2028. Tune in for a clear-eyed look at a controversial corner of climate tech.

Episode 123 of The Climate Tech Podcast tackles an overlooked decarbonization challenge: international shipping, which emits nearly a billion tons of CO2 annually. Lucas and Luna explore how one startup, Norsepower, is retrofitting cargo ships with rotor sails — massive spinning cylinders that harness wind to cut fuel consumption by up to 25 percent. They discuss the economics of retrofitting versus building new vessels, the role of alternative fuels like green ammonia and methanol, and why the industry's 2050 net-zero target feels both ambitious and achievable. The hosts also touch on regulatory pressure from the International Maritime Organization and how early adopters like Maersk are proving that cleaner shipping is commercially viable. If you're interested in industrial decarbonization or the supply chains behind everything you buy, this episode offers a grounded, specific look at a sector on the cusp of transformation.

Leather production has a massive environmental footprint — livestock accounts for 14.5% of global greenhouse gas emissions, and traditional tanning uses heavy metals like chromium. But a new wave of biomaterials is offering an alternative. In this episode, Lucas and Luna explore how one startup, MycoWorks, is growing leather-like material from mycelium — the root structure of mushrooms. They break down the science: how the company controls the growth conditions to create a material that mimics the strength and texture of cowhide, with a fraction of the water and land use. They also discuss the market reality — luxury brands like Hermès have already adopted it, but can it scale beyond high-end handbags? Lucas shares numbers: MycoWorks recently raised $125 million at a valuation over $1 billion, and their first commercial-scale facility in South Carolina is set to produce up to 15 million square feet annually by 2027. Luna challenges the hype, asking whether consumers will pay a premium for sustainability. The episode closes with a look at what it will take for mycelium leather to move from boutique to mainstream.
