Episode 052 - Live at Cerulean - Part II: Wave Energy, Ocean Tech & Microgrids: The Future Beyond the Grid?

Recorded live at Cerulean II in London organised by Samudra Oceans, this Raw Green episode explores one of the most overlooked areas in climate tech and energy infrastructure: the ocean. Our host Francesco De Lieto is joined by Ophelia Chua (CFO, Rypples) and Laura Duggan (CEO, Fetch Energy), the discussion moves from ocean automation and climate tech investment to wave power, microgrids, energy security, and the future of decentralised infrastructure. Together, they unpack: * Why ocean technologies are still lagging behind broader climate tech * Whether consolidation and M&A will reshape the sector * The real challenge of scaling ocean innovation: capital, deployment, and commercialization * A new approach to wave energy generation with simplified mechanics and no critical materials * Why bypassing the grid could unlock faster deployment and new business models * The rise of microgrids, local energy systems, and China’s net-zero industrial zones * Energy security, geopolitics, and the increasing urgency to deploy resilient infrastructure * Commercial maritime applications, electric vessels, and solving “range anxiety” at sea The conversation highlights a broader shift happening across energy systems: moving from centralized infrastructure toward more distributed, flexible, and locally integrated solutions. If you are interested in climate tech, blue economy innovation, wave energy, or the future of energy infrastructure, this episode offers a grounded look at where the sector may be heading next.

Episode 052 - Live at Cerulean - Part I: Deep Sea Mining Debate: Robots vs Regulation | Ocean Tech, Battery Metals & Unknown Ecosystems

Recorded live at Samudra Oceans Cerulean event in London, this Raw Green episode dives straight into one of the most controversial frontiers in climate tech: deep sea mining. Joined by Alexander Nesiah (Founder, nMech Robotics / Atlas) and Dr. Nick Hardman-Mountford (marine scientist, policy advisor), the conversation explores whether ocean-based mineral extraction is a necessary step for electrification — or a risk we still don’t understand. Together with Francesco and Emma, they unpack: * A radically different approach to deep sea mining using swarms of small robots instead of dredging * The environmental trade-offs between seabed extraction and land-based mining (rainforests, Congo, Indonesia) * The reality of how little we know about deep ocean ecosystems — and why that matters * “Dark oxygen” and new discoveries that could reshape our understanding of planetary systems * Regulation, the International Seabed Authority, and whether governance can keep up with technology * The tension between urgency (energy transition, AI demand) and the precautionary principle * Why major companies (Microsoft, BMW, Volvo, Google, and others) are already rejecting deep sea minerals This is not a settled debate — it’s a live collision between engineering ambition, scientific uncertainty, and global demand for critical minerals. If you care about ocean tech, climate infrastructure, or the future of resource extraction, this episode sits right at the edge of what comes next.

Episode 051 - What’s Really Inside a Battery? | EV Manufacturing, Defects & Gigafactories | Dan Brett

EV batteries, manufacturing, defects, and gigafactory scale explained. Battery production is scaling fast — but how much do we actually see inside the cells being produced? In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Dan Brett (CEO of Sention Technologies) about EV battery manufacturing, lithium-ion battery defects, and how gigafactories manage quality at scale. We cover where defects come from, why many issues only show up later, and how new diagnostic approaches like ultrasound can help detect problems earlier — across R&D, production, and second-life batteries. The conversation also explores scrap rates in gigafactories, energy use, battery recycling, and the broader supply chain challenges shaping battery production in Europe and globally. A grounded look at how battery manufacturing actually works today — and what changes when you can finally see inside the cell. Don’t forget to follow the podcast to catch the next episode.

Episode 050 - How Secure Is the Energy Transition? | Uri Sadot

The energy transition is accelerating — solar, storage, electrification. But as energy systems become more connected and more distributed, they also become more exposed. In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Uri Sadot, Managing Director of Solar Defend (https://solardefend.eu/) , about a topic that is quickly moving from theory to reality: cybersecurity in energy infrastructure. Uri explains how renewable energy assets — particularly solar — are increasingly treated as critical infrastructure, and why that shift is forcing a new level of attention from regulators, investors, and operators. The conversation covers real-world incidents, including coordinated attacks on energy assets in Europe, and what these mean for the future of the grid.  Beyond risk, the discussion moves into economics. * How much does it actually cost to secure a solar plant? * What happens when cybersecurity becomes a compliance requirement? * And should resilience be factored into how energy assets are valued and financed? The episode also explores the role of AI — both as a tool for attackers and defenders — and why, despite increasing complexity, most vulnerabilities still come down to basic “cyber hygiene”. From grid resilience to investment decisions, this conversation looks at how the energy transition is evolving from a question of deployment to one of maturity — and what it takes to build a system that is not only clean, but robust.

Episode 049 - Is Carbon Fibre Actually Sustainable? | Gary Owen

Carbon fibre is one of the most advanced materials in modern engineering. It makes aircraft lighter, electric vehicles more efficient, wind turbines stronger, and high-performance sports equipment possible. But behind these advantages lies a major challenge. Producing carbon fibre is extremely energy-intensive, manufacturing generates large amounts of waste, and recycling composites remains technically difficult. In this episode of Raw Green, Francesco De Lieto and Emma Mee speak with Gary Owen, CEO at Lineat (http://lineat.co.uk/), a UK climate technology company developing industrial processes to recover and reuse carbon fibre. Gary explains why carbon fibre recycling has historically been so difficult, why large amounts of composite material are wasted during manufacturing, and how new technologies could help bring circularity to one of the most important materials used in aerospace, automotive, and advanced manufacturing. The conversation explores the real carbon footprint of carbon fibre, the growing demand for lightweight materials in sectors like EVs and wind energy, and how recycled composites could become both a sustainability solution and a new industrial opportunity. From aircraft and Formula One to tennis rackets, electronics and electric vehicles, this episode looks at how advanced materials are shaping the future of engineering — and whether one of the most powerful materials ever developed can finally become circular.
