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.

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.

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.
