    #61 - The 380 Exajoule Opportunity | Rushad Nanavatty

    Energy efficiency offers savings and predictable returns, so why does climate-tech investment keep chasing new power generation? Recorded live at The Drop in Malmö (https://thedropconf.com/), Rushad Nanavatty, Managing Director at RMI (Rocky Mountain Institute - https://rmi.org/) and Third Derivative (https://www.third-derivative.org/), joins Francesco De Lieto and Emma Mee to explore the roughly 380 exajoules of primary energy that never become useful energy. From industrial heat pumps and grid flexibility to passive radiative cooling, we ask where the overlooked opportunities lie, and what makes these technologies bankable. Plus: financing first-of-a-kind projects, China’s clean-tech leadership, and why Rushad thinks climate repair will become a much bigger conversation.

    #60 - Climate Without Preaching | Stuart Goldsmith

    How do you talk about climate change without making people switch off? Comedian Stuart Goldsmith, host of The Comedian’s Comedian Podcast and creator of the touring climate comedy show Canary (https://www.stuartgoldsmith.com/), joins Francesco and Emma for a conversation about comedy, climate and communication. They get into climate dread, guilt and the impossible purity test; why sustainability needs to move from “values” to “value”; cancel culture, corporate gigs and greenwashing; and why stand-up comedians and climate-tech founders have surprisingly similar jobs: test, fail, adapt and try again. Then Stuart gets thrown into the world of climate tech - judging space-based solar, lab-grown meat, robots, engineered bacteria and sewage-to-jet-fuel on one simple question: will they save us or kill us? A funny, candid conversation about climate, technology, communication and why sometimes the best way to get people to listen is to stop preaching.

    #59 - Jet Fuel From Sewage: The Future of Sustainable Aviation Fuel? | James Hygate

    Can sewage really become sustainable aviation fuel? Francesco De Lieto and Emma Mee speak with James Hygate, founder of Firefly (https://flyfirefly.uk/), about turning wastewater biosolids into jet fuel using hydrothermal liquefaction (HTL) - and whether this new pathway can compete with HEFA, e-SAF and conventional Jet A-1. James explains why sewage could be such a valuable SAF feedstock, how Firefly’s process works, its relationship with wastewater companies, what happens to the bio-crude and biochar, and whether wet waste could ultimately provide enough fuel to make a meaningful dent in aviation emissions.  We also get into SAF pricing, Book & Claim, regulatory dependence, cost parity and Firefly’s 15-year, 525,000-tonne offtake agreement with Wizz Air.  And there’s James’s wider story: more than 20 years in low-carbon fuels, from building a biodiesel refinery in his parents’ garage to supplying the Royal Family, receiving a Royal Warrant and later an OBE for services to low-carbon fuels.  We cover: Why SAF still makes up less than 1% of aviation fuel useHEFA, e-SAF and why some SAF pathways are much more expensive than othersWhy used cooking oil is becoming an increasingly constrained feedstockHow hydrothermal liquefaction turns sewage biosolids into bio-crudeWhy wastewater could be such a valuable low-cost SAF feedstockFirefly’s model with water companies and wastewater treatment plantsBook & Claim, mandates and how dependent SAF still is on regulationFirefly’s 15-year, 525,000-tonne offtake agreement with Wizz AirWhether wet waste could produce enough fuel to materially decarbonise aviationJames’s 20+ year journey from Green Fuels to Firefly, the Royal Warrant and his OBE Don’t forget to follow our podcast to catch the next episode.

    #58 - Renewables Are Winning. You Just Don’t Know It Yet | Bruce Douglas

    Renewables are scaling faster, getting cheaper and increasingly becoming an energy-security play. So why does the public and political conversation still make them sound expensive, unreliable and risky? In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Bruce Douglas, CEO of the Global Renewables Alliance (https://globalrenewablesalliance.org/), about the gap between what is happening in global energy markets and the story people are being told.  We get into fossil-fuel misinformation, subsidies, electricity pricing, North Sea drilling and why Bruce believes the renewables sector is still badly outgunned when it comes to communications.  But the conversation is also about what happens next: grids, storage, permitting, electrification, microgrids and the practical steps governments need to take to get close to 11,000 GW of renewable capacity by 2030.  We cover: Why renewables are still losing the argumentFossil-fuel subsidies and political messagingWhy more drilling does not necessarily mean cheaper energyGrids, storage and the case for microgridsGRA’s Electrify Now campaignNuclear and the future power mixThe four things governments need to do nowWhere the best renewable-energy success stories are already happening Useful links: Global Renewables Alliance Electrify Now InfluenceMap – Fossil Fuel Misinformation Tracker Global Renewables Summit Don’t forget to follow our podcast to catch the next episode.

    #57 - Can Small Wind Finally Take Off? | Daniel Farb

    Small wind has been around for decades. So why has it never taken off like solar? In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Daniel Farb, CEO of Flower Turbines (https://www.flowerturbines.com/), about whether small vertical-axis wind can finally move from niche technology to serious distributed energy. Flower Turbines is trying to tackle many of the problems that have held small wind back: cost, noise, vibration, aesthetics, siting and poor economics. Its key innovation is the “bouquet effect”, where turbines installed close together can improve each other’s performance. But technology is only part of the story. Unlike solar, where generation forecasts can be built quickly from highly mature irradiance datasets, small wind still faces a harder problem: proving output with enough confidence to support a robust financial case without making project development prohibitively expensive. We cover: Why small wind has historically disappointedHow commercial deployments are assessedFlower Turbines’ technology and bouquet effectThe economics of clustered installationsSelling electricity instead of turbinesManufacturing, China and IPUK vs US market dynamicsWhat small wind still needs to compete with commercial solar Can small wind finally take off?

    #56 - Cooling Buildings Without More Air Conditioning | Molly Allington

    When buildings overheat, the usual answer is simple: add more cooling. But what if part of the solution was not another machine, but a material? In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Molly Allington, CEO and co-founder of Albotherm (https://albotherm.com/), a Green Angel Ventures portfolio company developing heat-responsive coatings and films for glass. Albotherm’s technology is clear when it is cooler and turns white and reflective when temperatures rise, helping to reduce solar heat gain before air conditioning is needed. The company began by working on greenhouse coatings, where overheating can affect crops, workers and yields, and is now moving into retrofit window films for homes, offices, schools, public buildings and commercial spaces. The conversation covers passive cooling, building overheating, energy efficiency, climate adaptation, solar-control films, greenhouse trials, Part O overheating regulations, public health, product durability, environmental trade-offs, and the manufacturing challenges of scaling a materials start-up. If we want buildings to cope with hotter summers without simply increasing electricity demand, technologies like Albotherm may become part of the next wave of practical climate adaptation.

    #55 - How climate tech earns serious capital | Bailey Morrow

    How does climate tech earn serious capital? In this episode of RAW GREEN, Francesco De Lieto and Emma Mee sit down with Bailey Morrow, Managing Director at HSBC Innovation Banking (https://www.hsbcinnovationbanking.com/en), to unpack one of the biggest bottlenecks in climate tech: bankability. Many climate technologies can prove they work through pilots, LCA data, early customers and technical milestones. But proving that a technology works is not the same as proving it is financeable. Bailey explains what lenders actually look for when assessing climate tech companies, why debt moves differently from venture capital, and why founders often confuse being VC-fundable with being bank-financeable. The conversation covers the gap between technical validation and commercial maturity, the role of liquidity, customer contracts, offtake agreements, recurring revenue, and the importance of building lender relationships early. The episode also explores the differences between the US, UK, Europe and China when it comes to climate tech scale-up, risk appetite, speed of execution, regulation and deployment. From software-enabled climate tech to hardware, FOAK projects, project finance, venture debt and customer-side financing, this is a practical discussion on what it really takes for climate technologies to move from promising innovation to serious capital. If you are a climate tech founder, investor, lender, corporate buyer or anyone working on scaling clean technologies, this episode is a clear guide to how capital thinks , and what climate tech needs to prove before banks lean in.

    #54 - Can Rocks Remove CO₂? Enhanced Rock Weathering | Mat Meredith

    In this episode of RAW GREEN, Francesco De Lieto and Emma Mee speak with Mat Meredith, Chief Technology Officer at UNDO (https://un-do.com/), about enhanced rock weathering, one of the most promising carbon removal pathways with real gigatonne potential. Enhanced rock weathering sounds almost too simple: take crushed silicate rock, spread it on land, let rain and soil chemistry do the work, and remove CO₂ from the atmosphere. But behind that simple idea sit some of the hardest questions in climate tech: how do you prove the carbon has actually been removed, how do you measure it across messy real-world soils, and how do you turn it into a credible carbon credit? Mat explains how ERW works in plain English, why different rocks such as basalt and wollastonite behave differently, what happens to the captured carbon over time, and why MRV (measurement, reporting and verification) is the key challenge for the sector. We also discuss UNDO’s work with farmers and landowners, the soil-health benefits of spreading crushed rock, the carbon footprint of quarrying and processing, the instability of the carbon credit market, and what needs to happen for ERW to become bankable and scalable. A conversation about rocks, rain, soil, carbon removal, climate finance, and whether enhanced rock weathering can become one of the major tools in the fight against climate change.
