Scaling Green-Tech

Episode summaryDarren Clifford, Co-Founder of Adapt [us] Capital, discusses the investment case for climate adaptation on Episode 28 of Scaling Green Tech, a podcast by Adopter. Clifford argues that adaptation is more underfunded than mitigation, with roughly 0.25% of global capital flowing to it, despite demand for adaptation products rising predictably as the weather gets hotter and more volatile. Adapt [us] Capital backs pre-seed companies that meet three tests at once: a venture-grade team and market, demand driven by changing weather, and a measurable improvement to quality of life. He uses portfolio company Temperate, a passive radiative cooling business, to illustrate the thesis, alongside Bactery, which builds soil-based batteries for resilient backup power. Clifford frames the whole portfolio as a hedge against a future where changing climate could erode between 5% and 25% of global GDP by 2050.This episode is relevant for climate adaptation investors, pre-seed and seed-stage climate founders, family offices and high net worth LPs evaluating adaptation funds, and operators working on go-to-market for hardware and deep tech in new geographies.

Freya Burton, Chief Sustainability Officer and Head of Europe at LanzaTech, discusses carbon recycling, sustainable aviation fuel, and the 20-year journey from a four-person startup to a public company on Episode 27 of Scaling Green Tech, a podcast by Adopter.
Burton describes how LanzaTech captures waste carbon from industrial sites such as steel mills and uses microbes to ferment it into ethanol, a process she likens to brewing beer with carbon instead of sugar and bacteria instead of yeast. She traces the company from its 2005 founding in New Zealand by Dr Sean Simpson and Dr Richard Forster, through a 2008 pilot and a 2012 demonstration plant in China, to its first commercial plant in 2018 and six plants today. The conversation turns to why LanzaTech narrowed its focus to sustainable aviation fuel after listing on the Nasdaq, and how it reframes its work around energy security and economic value rather than emissions alone. Burton also explains why getting fuels policy right has taken more than a decade of work across the UK, EU and US.
This episode is relevant for founders scaling capital-intensive climate tech, carbon capture and utilisation investors, sustainable aviation fuel producers and buyers, and policymakers working on fuels regulation. 

Guest profile
Freya Burton is the Chief Sustainability Officer and Head of Europe at LanzaTech. She joined the company in 2007 as one of its first four employees, working in borrowed lab space, and has since held roles spanning safety, human resources, external affairs and policy. She previously served as the company's Chief People Officer and spent a long period based in the United States before moving into her current sustainability and Europe-focused leadership role.
LanzaTech is a carbon recycling company that converts waste carbon from industrial emissions into ethanol and other chemicals using a gas fermentation process. Founded in New Zealand in 2005 and now listed on the Nasdaq, the company operates six commercial plants worldwide across steel mills, ferro alloy mills and a refinery. It supplies ethanol made from recycled carbon, and related materials, to consumer brands in fashion, fragrance and household goods.

Dr Robert Sorrell, CEO of the Royce Hydrogen Accelerator at the Henry Royce Institute, discusses materials innovation and the hydrogen value chain on Episode 26 of Scaling Green Tech, a podcast by Adopter.Sorrell treats hydrogen as one part of the wider energy mix rather than a fix-all. The strongest near-term use is as a feedstock for ammonia, fertilisers and industrial chemicals. Long-duration storage of surplus offshore wind is another priority, particularly in the UK. Shipping and aviation also stand out, because batteries cannot match the energy density needed for large vessels or long-haul flight. The episode also covers the $1-2 per kilogramme cost target for green hydrogen, the materials problem of cryogenic storage at -253°C, and the funding gap atthe proof-of-concept and prototyping stages.The episode is useful for hydrogen founders, deep tech investors, electrolyser and fuel cell developers, and policymakers working on the UK's hydrogen strategy.

Karen Polizzi, Co-Director of NAPIC (the National Alternative Protein Innovation Centre), and Prithvi Kodialbail, Head of Partnerships at Extracellular, discuss the commercialisation of cultivated meat on Episode 25 of Scaling Green Tech, a podcast by Adopter.The first cultivated meat burger cost approximately $27,000 to produce. Since then, regulatory approvals have come through in Singapore and the US, cultivated products have appeared in restaurants, and an infrastructure layer of companies has begun filling the gap between R&D and commercial scale. Polizzi and Kodialbail trace where the bottlenecks remain - manufacturing costs, regulatory harmonisation, and access to facilities - and describe how NAPIC and Extracellular are each working to close those gaps in the UK. The conversation also makes the case for food security, rather than sustainability, as the most compelling argument for alternative proteins, set against real long-term agricultural risk in the UK.This episode is relevant for cultivated meat founders, alternative protein investors, food science researchers, and policymakers working on UK novel foods regulation.Find out more about Adopter here: https://www.adopter.net/Explore NAPIC here: https://napic.ac.uk/Discover Extracellular here: https://www.extracellular.com/

Mahima Sukhdev, Chief Growth Officer at GIST Impact, discusses the evolution from ESG 1.0 to ESG 2.0, nature value at risk, and what it takes to grow a data company in an emerging market on Episode 24 of Scaling Green Tech, a podcast by Adopter.
Sukhdev argues that ESG 1.0 was designed to produce glossy numbers for glossy reports, and was never intended to change how decisions are made. GIST Impact was built on a different premise: that climate, nature, and social data should be traceable, methodologically rigorous, and fed directly into the places where decisions happen - portfolio construction, stewardship, capital allocation. Founded 18 years ago as a research lab, GIST has watched this shift play out in real time. A major Indian bank is already seeing default rates rise in its agricultural loan book in ways that can only be explained by climate and nature risk. Clients like Allianz and StoreBrand are now using nature data to build portfolio-level analyses that would have seemed out of reach just a few years ago. GIST's recently launched Nature Value at Risk (NVaR) Solution - built on 25 critical ecosystem services and the Natural History Museum's Biodiversity Intactness Index - is its most detailed attempt yet to put a financial number on what happens when ecosystems fail.
This episode is for asset managers, impact investors, corporate sustainability leads, and founders building in the ESG data or nature risk space.
