Green hydrogen has had a punishing few years, with cancellations, cost overruns and demand that arrived late. So why did Schroders Capital keep investing while others retreated?Holly Turner and Duncan Hale join Climate Solutions News ahead of Reset Connect London 2026 to explain the firm's approach. Duncan walks through the Barrow Green Hydrogen Project in Cumbria, which will supply hydrogen to a Kimberly-Clark factory making Andrex and Kleenex, and the subsidy model borrowed from wind and solar. Holly maps where climate capital flows next, the growing case for adaptation and resilience, and how European regulation is reshaping what counts as a sustainable investment.A conversation about sticking to your convictions, delivering energy transition projects and where the next phase of the transition gets funded.

How is AI changing the way we measure the carbon cost of what we build? One Click LCA founder and CEO Panu Pasanen joins the Climate Solutions News podcast to explain.Life cycle assessment counts the full environmental cost of a product or building, from raw material to disposal. It is rigorous work, and traditionally slow. Pasanen explains what the discipline involves, why embodied carbon is so much harder to act on than the energy a building uses, and how his company cuts an assessment that once took weeks down to something that fits the pace of a live project.He also looks ahead to AI that proposes whole low-carbon design options, with the human expert steering rather than building. On whether that output can be trusted, his answer is blunt: control, not trust. The platform monitors its AI constantly, tests it against large datasets, and grades the confidence of every proposal.Recorded ahead of Reset Connect London, 23 and 24 June 2026, where Pasanen is speaking on supply chain decarbonisation and Climate Solutions News is a media partner.Read more at https://climatesolutions.news/sectors/we-dont-trust-it-we-control-it-one-click-lca-uses-ai-to-cut-embodied-carbon

UNDO Carbon can prove its science works. The harder problem is paying for the years between spending on deployment and earning the carbon credits back, and that financing gap, more than the chemistry, is what now decides how fast enhanced rock weathering can grow.Dominic Shales speaks with Alex Bury, head of finance at UNDO, about the economics of scaling carbon removal. They discuss why enhanced rock weathering leans on existing mining and farming infrastructure rather than expensive capital equipment, the move from upfront payments to payment on delivery, and UNDO's debt deal with the Inlandsis Fund alongside a Microsoft offtake. Bury also covers carbon removal insurance, the significance of Farm Credit Canada's investment, the measurement challenge behind lender confidence, and what it takes to bring a first-time buyer like Barclays into the voluntary carbon market.UNDO was a winner in the $100 million XPRIZE Carbon Removal competition. Its buyers include Microsoft, Barclays, British Airways and McLaren Racing.More at https://climatesolutions.news

Heavy industry produces the materials that the modern world runs on. It also produces around a quarter of global greenhouse gas emissions. Cement alone accounts for roughly 8% of global CO₂, a share that has barely moved in decades. Most of the plants responsible are old, complex, and still running on control systems that were never built for the world they operate in today.This week, Dominic Shales speaks with Buffy Price, co-founder of Gigaton, the AI company replacing control software in energy-intensive industries. Formerly known as Carbon Re and spun out of the University of Cambridge and UCL, Gigaton has just announced a $26 million Series A led by Plural, taking total funding past $35 million.Buffy explains how Gigaton's self-learning platform takes autonomous control of industrial processes, delivering up to $3 million in annual operational savings per plant for customers including Adani Cement, Heidelberg Materials, and Holcim. She talks through the journey from recommendation dashboards to direct plant control, the rise of dark factories in China, and the company's plans to expand from cement into steel, glass, and petrochemicals.They also discuss what it takes to raise a Series A in the current climate investment market, how CBAM and ETS are shifting producer incentives, and why carbon capture and AI process control are complementary rather than competing solutions.Find climate tech news, analysis, and interviews at Climate Solutions News.Chapters:00:00 The Impact of Heavy Industry on Climate Change03:02 Gigaton's Mission and Ambitions06:11 Funding and Financial Viability in Tough Times08:48 Automation and AI in Cement Production11:54 Cultural Shifts in Industry and AI Adoption15:11 Global Expansion and Market Strategy17:57 Policy Impacts on the Cement Industry21:10 Expanding into Other Hard-to-Abate Industries23:53 Buffy's Journey and Vision for the Future

The headlines say climate investment is in retreat. Duncan Reid is not convinced.In this episode of the Climate Solutions News podcast, Dominic Shales sits down with the chief executive of Reset Connect, the green investment event that anchors London Climate Action Week. Reid has spent 25 years in events and now watches climate capital up close, with investors, founders and corporate buyers gathering under one roof each June.His argument is that the money has changed hands and crossed borders, away from the loudest US funds. Large managers have stepped back as Washington unwinds its climate incentives. Yet pension funds and institutional investors keep allocating, because their obligations stretch across decades. As Reid puts it, "if the UK is all on fire or underwater, people don't need pensions."The conversation turns to the war in the Gulf and the rise of energy sovereignty, the maturing of the sector since 2022, the long struggle to fix the grid, and why Reid believes the economics of clean power now win whatever the politics.Read the article here.

What if the carbon dioxide coming out of a factory could go straight into growing protein? That is the logic behind Arborea's BioSolar Leaf technology, and it is attracting serious interest from some of the world's largest food companies.Dominic Shales speaks with Dr Kaly Chatakondu, Global Commercial Director at Arborea, about the London-based startup that has spent a decade industrialising photosynthesis to cultivate microalgae at commercial scale. Kaly brings more than 30 years of senior food industry experience and a chemistry doctorate from the University of Oxford. He explains how the BioSolar Leaf system works, why its economics and contamination profile solve problems that have held back the microalgae sector for decades, and how Arborea is building its first full commercial factory in Portugal while quietly assembling a portfolio of offtake agreements with major multinationals. The conversation covers the AB InBev collaboration in Mexico, the regulatory landscape for novel food ingredients, and what a global rollout via joint ventures and technology licensing could look like.TakeawaysThe food system accounts for a third of global greenhouse gas emissions.Arborea's BioSolar Leaf technology industrializes photosynthesis.Microalgae can be cultivated on non-fertile land.The process is carbon negative and environmentally friendly.Spirulina is a key product due to its high protein content.Arborea collaborates with major food companies for product development.The technology can utilize CO2 from various industrial processes.Regulatory hurdles exist but are manageable for approved microalgae.Arborea's approach overcomes limitations of previous microalgae production methods.Global expansion plans include partnerships and licensing opportunities.Sound Bites00:00 "What if protein could be grown from CO2?"03:27 "It's photosynthesis on steroids."09:49 "Microalgae are superfoods."15:26 "This is completely unique technology."Chapters00:00 Introduction to Climate Solutions and Protein Production01:09 Transitioning to Arborea and BioSolar Leaf Technology03:56 Understanding BioSolar Leaf: The Process of Industrial Photosynthesis05:30 Environmental Benefits and Carbon Negative Process06:41 Product Focus: Spirulina and Its Versatility08:13 Collaborations with Major Food Companies10:03 Industrial Partnerships and Future Plans12:07 Navigating Food Regulations in Europe14:21 The Importance of Regulation in Food Safety15:04 Arborea's Unique Approach to Microalgae Production17:13 Global Expansion Plans and Market Strategies19:06 Funding and Investment Strategies20:51 Conclusion and Future Outlook

Ammonia production has barely changed in 100 years. It still relies on the Haber-Bosch process, runs at extreme temperatures and pressures, and accounts for close to 2% of global greenhouse gas emissions. But with ammonia now emerging as a leading candidate for zero-carbon maritime fuel and a hydrogen carrier for the energy transition, the pressure to decarbonise its production has never been greater.In this episode, Dominic Shales speaks with Karen Baert, co-founder and CEO of San Francisco-based Ammobia, which is developing what it calls Haber-Bosch 2.0: a modular ammonia production technology that operates at ten times lower pressure and 150 degrees Celsius lower temperature than conventional facilities, cutting capital costs by up to half.In January 2025, Ammobia closed a $7.5 million seed round backed by Shell Ventures, Air Liquide, Chevron Technology Ventures, and MOL Switch, the venture capital arm of Mitsui OSK Lines.Karen and Dominic discuss why conventional ammonia has been so difficult to decarbonise, why cost matters more than carbon in today's market, how modular production close to end users changes the economics, and what the rapid growth of ammonia-fuelled shipping means for the industry's future.Karen also reflects on her journey from Belgium to Stanford, co-founding Ammobia with Tristan Gilbert, and what it takes to commercialise deep industrial technology as a startup.Karen Baert was named Women Scientist of the Year at the Women in Energy Transition Awards 2025 and won the Women in Cleantech and Sustainability Pitch Competition 2025. Ammobia was named a World Economic Forum Technology Pioneer 2025, and its co-founders were recognised in Forbes 30 Under 30 Manufacturing and Industry 2024.🌍 Read the full feature on Climate Solutions News: https://climatesolutions.news 📧 Subscribe to the CSN newsletter for weekly climate policy and technology analysis.

France produces more biomethane than almost any other European country, yet a significant share of its agricultural biogas potential goes untapped. The reason: most farms sit too far from the gas grid to make connection viable, and the infrastructure cost runs to 100,000 euros per kilometre.Jules Vasse, head of public affairs at SUBLIME Énergie, joins Climate Solutions News Publisher Dominic Shales to explain the company's answer to that problem. SUBLIME liquefies raw biogas directly on the farm using a patented carrier agent, collects it by truck every few days, and separates it into bio-LNG and liquid bioCO2 at a centralised hub shared across multiple farms. The model bypasses the gas grid entirely.In April 2026, SUBLIME inaugurated Charlie, the world's first on-farm biogas liquefaction system, at a pig farm in Brittany. Jules talks through what the demonstrator means for the company's development, what comes next with the Delta commercial project, and how France's new IRICC carbon intensity regulation could transform the economics of bio-LNG for heavy transport.With the Strait of Hormuz crisis disrupting European LNG supply, the conversation around domestic renewable gas has become more urgent. This episode explores why farm waste may be one of the more practical answers.
