How Climate Tech Gets Out of the Lab | Prof. Vikram Yadav
Most Bite-Size Climate Tech episodes start with one technology. This conversation became something much bigger. Professor Vikram Yadav happened to be in London, the weather cooperated, and we recorded one of those rare in-person BSCT episodes. We start with intelligent bioprocessing and a deceptively simple question: when does a scientific invention actually become innovation? From there, we explore why climate technologies need to be designed for scale from the beginning, why commercial reality matters alongside scientific performance, and why scientists should be bold enough to ask how their inventions might fail. We also talk about how to bring more talented people into climate work, Vikram’s journey from chemical engineering and oil & gas into biotechnology, the book that helped him see biology as a tool for planetary-scale problems, and why he remains optimistic about the next generation. Vikram is a professor at the University of British Columbia and Co-Founder & Chief Scientific Officer of Tydra Labs. One idea became the spine of the conversation: There is a difference between invention and innovation. A breakthrough only becomes innovation when it works in the real world, at scale. Recorded in London, May 2026. Season 5: Climate Tech Is Just Good Business. #ClimateTech #Bioprocessing #Innovation #ScienceCommunication

Can Cement Be Made With 85% Less CO₂ at the Same Cost? | Erin Bobicki, CURA
Cement’s hidden CO₂ problem begins inside the rock itself. Much of cement’s emissions does not come only from the fuel burned in a kiln. The CO₂ is chemically locked inside limestone. Dr. Erin R. Bobicki, co-founder and CEO of CURA, joins Lydia Chen to explain how the company aims to separate that CO₂ before the limestone enters the cement kiln. Using the familiar reaction between vinegar and chalk, Erin breaks down CURA’s electrochemical pre-calcination process: electricity produces acid and base, the acid releases a concentrated stream of CO₂ from limestone, and the remaining calcium can still be used to make cement. They explore: • Why cleaner kiln fuel cannot solve cement’s full emissions problem • How CURA captures CO₂ before the kiln • The volcano experiment that makes the chemistry understandable • CURA’s pathway from laboratory work to paid pilot and commercial deployment • How carbon pricing is changing the economics of cement • The northern Labrador experience that deepened Erin’s commitment to climate • Why the cheapest option must also become the greenest option CURA says its process could reduce cement-production emissions by up to 85% and manage the carbon at cost parity with conventional cement manufacturing. But the final thought that stayed with Lydia was more personal. Erin has six children, and they are already excited about the technology and the mission behind it. As Erin put it: “The next generation is already on it.” Since this conversation was recorded, CURA has announced that its 5 kg/day mini-pilot is operational: https://curaclimate.com/press/curas-mini-pilot-is-operational Watch on YouTube: https://youtu.be/c-ggbzQILno Learn more about CURA: https://curaclimate.com/ Explore Bite-Size Climate Tech: https://www.dayzeroproduction.com/bite-size-climate-tech Support Season 5: https://www.dayzeroproduction.com/bite-size-climate-tech/support Figures, commercial claims, and deployment plans reflect CURA’s statements at the time of recording.

The Protein Shake for Batteries? How LiRA Restores Lithium-Ion Packs | BSCT S5E4
Alex Ivanenko is back on Bite-Size Climate Tech. He first joined the show in Season 2 to talk about HyWatts and hydrogen reversible fuel cells. This time, he returns with a new company, The Lithium Company, and a new idea: LIRA, the Lithium Inventory Refill Agent. The simplest version? A protein shake for batteries. In this conversation, Alex explains why some lithium-ion batteries may not be structurally dead, but depleted. We talk about active lithium inventory, battery restoration, the difference between recycling, repurposing, and restoring, and why this could become a good-business answer to replacement pressure. We also talk about validation, commercialization, and why Alex keeps building in energy: because better, cheaper, more effective energy technologies can improve quality of life and expand access to electricity. This is an early-stage story, but it captures the heart of Season 5: climate tech is just good business when it solves a real problem. Note: Some visual explainers in the video version are AI-assisted and illustrative only. They are not technical demonstrations, validated test results, or performance guarantees.

Can We Grow Oil From Algae? Ian Hu of Phycobloom
Algae already make oil. The hard part is getting them to share it. In this episode of Bite-Size Climate Tech, Lydia speaks with Ian Hu, CTO and co-founder of Phycobloom, a synthetic biology company engineering microalgae to release oil while staying alive. Ian explains why crude oil originally came from ancient photosynthetic life, why traditional algae oil production was so energy-intensive, and how Phycobloom is exploring a different approach: teaching algae to release oil into their surroundings without destroying the cell. The conversation covers algae 1.0, DNA as an instruction manual, synthetic biology, the “Monsters, Inc. 2.0” analogy, sustainable aviation fuel, energy security, techno-economics, and why climate startups need to think beyond the science from day one. We also discuss Phycobloom’s internal techno-economic analysis, which suggests their approach could reduce production cost compared with conventional algae oil production by around 70 percent. This is early-stage science, but it points to a big question: could living systems become a better way to make the carbon-based fuels and materials that electrification cannot easily replace? Bite-Size Climate Tech Season 5 is about why climate tech is just good business. Note for video viewers: selected B-roll and animations in the video version are AI-assisted and used as educational explainers. The interview and company context are real.

Can CO₂ Become Food? Arborea’s BioSolar Leaf Explained
Giving EV Batteries an NthLife™ with Samsar Resources
What happens to an EV battery after it stops powering a car? In the opening episode of Bite-Size Climate Tech Season 5, Lydia speaks with Guillermo Garcia, President and CEO of Samsar Resources, about battery circularity, reuse, and the company’s NthLife™ approach. Samsar designs, inspects, and repurposes batteries so they can keep creating value across new applications instead of being discarded too early. We talk about why battery reuse is not just good for the planet, but also good business, how to explain the idea through a Toy Story analogy, and what it takes for climate technology to move from lab to market. This episode kicks off Season 5’s new theme: Climate Tech Is Just Good Business. Bite-Size Climate Tech makes complex climate solutions simple, human, and engaging.

From lab to market, Season 5 of Bite-Size Climate Tech
Season 4 Finale - Sunlight‑Powered CO₂ Capture & K‑Pop Carbon Tales
In this Bite‑Size Climate Tech finale, Dr Anna de Vries takes us from lab bench to lemonade stand to explain how photoacids could make carbon capture cheaper and greener. Traditional systems use heat or electricity to release CO₂, but Anna’s solution uses light‑reactive molecules that switch from alkaline to acidic under sunlight. In darkness they flip back, allowing CO₂ to be captured again. This swing cycle runs at ambient temperature and pressure and requires far less energy than conventional methods . Along the way, we explore how this new science ties into pop culture (yes, there’s a K‑pop “soda pop” reference), why a young researcher chose climate tech over other paths, and how a cultural shift among the wealthiest could drive climate action. Anna closes the season with a simple message: no impact is too small .

“BetterFeed™ – The tiny pill turning cow burps into productivity
Cows are upcyclers, turning grass into milk and meat—but their digestion also wastes up to 10 % of feed energy as methane. Methane has a global warming potential ~28–80× higher than CO₂. Our guest, Tom Williams (CEO & co‑founder of Number 8 Bio), explains how his team screened thousands of compounds to create BetterFeed™ , a small organic molecule delivered in a slow‑release bolus . Once in the rumen, it prevents methane‑producing microbes from growing and redirects carbon and hydrogen back into growth . In trials, BetterFeed has cut methane emissions by over 80 % while improving weight gain and milk quality. Tom also answers a listener question about taking a technology from TRL 2 to TRL 7, shares why he’s been thinking about methane since his childhood in rural New Zealand, and leaves us with a hopeful note: humans have only scratched the surface of what’s possible.
