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

Episode 106 explores the rise of solar canopies over parking lots. Lucas and Luna break down the economics of dual-use infrastructure, using Walmart's rollout of canopies at 100 locations as their anchor. They compare costs versus ground-mount solar, discuss the added revenue from EV charging tie-ins, and explain why parking-lot PV could add 50 gigawatts of capacity in the US without competing for farmland. Specific numbers include a 20 percent premium on installation cost and a 15-20 year payback period. The conversation also touches on policy drivers like the Inflation Reduction Act's investment tax credit and municipal zoning changes. By the end, listeners understand why a mundane asphalt surface might be one of the most underrated climate assets.

Lucas and Luna explore a climate tech startup called CarbonOro that turns olive pomace — the wet, fibrous waste from olive oil production — into biochar and locks away carbon for centuries. They walk through the numbers: the 10.8 million tons of olive pomace generated annually in the Mediterranean basin alone, the price of premium biochar credits at $500 per ton, and the accounting challenge of verifying that the carbon actually stays put. Along the way, they discuss the tension between carbon removal durability and the economic incentives of the voluntary carbon market — and why olive waste might be a sleeper hit in the CDR space.

Not all carbon removal credits are created equal. In this episode, Lucas and Luna break down the growing price divergence in voluntary carbon markets. They look at why permanent removal credits from direct air capture and enhanced weathering trade for $200 to $600 per ton while nature-based offsets like forestry credits linger below $10. The hosts examine the role of the Core Carbon Principles from the Integrity Council, Microsoft's offtake agreements with Heirloom and Lithos, and how buyers like Stripe and Frontier are creating a tiered market. Luna pushes back on whether price alone signals quality, and Lucas explains why durability of storage duration is the key metric splitting the market. A concrete look at how quality is being defined in a market that critics say lacks transparency. Relevant for anyone tracking net-zero commitments, carbon credit buyers, and climate tech investors.

In this episode of The Climate Tech Podcast, Lucas and Luna explore how a small startup called Fungalytics is using specially engineered fungi to degrade polypropylene plastic — one of the most common and hardest-to-recycle plastics. They dive into the science: how the fungus produces enzymes that break down polymer chains at room temperature, the pilot plant in Ohio that processes 10 tons of plastic per month, and the economics — can this compete with virgin plastic at $1.20 per kilogram? They also discuss the company's partnership with a major packaging firm and the regulatory hurdles ahead. A deep look at a promising but early-stage solution to the plastic crisis.

Episode 102 of The Climate Tech Podcast explores a surprising use for captured carbon: synthetic diamonds. Lucas and Luna dive into how one startup, Aether Diamonds, is pulling CO2 directly from the air and using it to grow gem-quality diamonds in a reactor. Unlike mined diamonds or even other lab-grown diamonds that use methane feedstocks, Aether's process is carbon-negative per carat. They discuss the chemistry, the economics—roughly $800 per carat to produce—and whether this is a genuine climate solution or a clever marketing play for luxury goods. The hosts also touch on the broader category of 'carbon-to-value' startups and the challenge of scaling beyond novelty products.

Concrete is everywhere — but its production generates about eight percent of global CO2 emissions. In this episode of Climate Tech Podcast, Lucas and Luna explore how a new generation of startups is turning concrete from a carbon source into a carbon sink. They look at one company in particular: CarbonCure, which injects captured CO2 into fresh concrete, where it mineralizes and stays permanently. Lucas breaks down the chemistry, the economics (about $15 per cubic yard premium), and the scale challenge: only about 800 ready-mix plants worldwide use the technology so far versus tens of thousands globally. Luna asks about competition from alternative binders like those from Solidia, and whether carbon-sequestering concrete could qualify for Section 45Q tax credits. The episode lands on a concrete question: can we retrofit an entire industry before the next building boom locks in decades of emissions?

In this milestone 100th episode, Lucas and Luna explore an emerging frontier in carbon removal: direct ocean capture. They focus on one startup, Ebb Carbon, which uses an electrochemical process to remove CO2 from seawater while producing hydrogen as a byproduct. Lucas explains the chemistry—how the process creates an acid and a base stream, with the base being returned to the ocean to absorb more CO2 from the atmosphere. They discuss the company's recent $20 million funding round, their pilot on the Washington coast, and the potential scale: the ocean holds 50 times more carbon than the atmosphere. Luna questions the energy requirements and costs, which currently hover around $200 per tonne of CO2 removed. They compare ocean capture to direct air capture, noting the advantage of working with already-dissolved CO2. The conversation touches on permanence, monitoring, and the challenges of scaling. The episode ends with a look ahead at the potential for gigaton-scale ocean carbon removal by mid-century.

Episode 99 of The Climate Tech Podcast explores thermoelectric generators — devices that convert waste heat from industrial processes into usable electricity. Lucas and Luna dive into a specific startup, Heat2Power, which has deployed its solid-state modules at a German steel mill, capturing 500 °C exhaust heat to generate 1.2 megawatts of power. The conversation covers the physics of the Seebeck effect, the efficiency gap compared to traditional steam turbines, the cost trajectory from $5 to $0.80 per watt, and the potential to retrofit millions of industrial smokestacks globally. They also discuss how the technology complements renewables by providing baseload clean power without moving parts. A concrete look at a niche but scalable decarbonization play.

Episode 98 of The Climate Tech Podcast explores the growing challenge of solar panel waste and the startups turning it into a resource. Lucas and Luna dig into the numbers: by 2030, the world will have generated over 8 million metric tons of decommissioned panels. They profile one company, SolarCycle, that has developed a process to recover 95% of the materials — including silver and high-purity silicon — and sells them back into manufacturing at a profit. The hosts discuss the economics of recycling versus landfilling, the regulatory push in Europe and California, and why this matters for the clean energy transition. A concrete, numbers-driven look at a problem most people don't know exists.

Episode 97 of The Climate Tech Podcast explores a surprising solution to synthetic fertilizer's massive carbon footprint: desert algae. Lucas and Luna dive into how one startup is harvesting extremophile microalgae from the Sahara and turning it into a biological nitrogen fertilizer that could slash agricultural emissions by 30 percent. They break down the science — desert algae fix nitrogen without fossil fuels — and the economics: the startup claims its product can match synthetic fertilizer on cost while rebuilding soil health. The conversation covers trials on wheat fields in Morocco, the challenge of scaling production from lab to thousands of hectares, and why this isn't just another biofertilizer hype story. Listeners learn one concrete number: replacing just 10 percent of global synthetic nitrogen use with desert algae would cut carbon dioxide equivalent emissions by roughly 100 million tons per year. No vague promises — just a specific, investable case in the business of decarbonizing agriculture.
