Sustainability In The Air

In this episode, we speak with Silvia Pugliese and Monica Larrazabal, co-founders of Norma and the only all-female founding team among the c.150 direct air capture startups operating today. They share how their breakthrough supercapacitor approach could drastically slash the energy requirements of carbon capture.Pugliese and Larrazabal discuss:How they discovered a way to "cheat" on energy requirements by combining supercapacitor energy storage technology with CO2 capture, creating a hybrid device that recycles energy through each capture cycle.Their modular approach with desk-sized units that can be deployed anywhere, contrasting with competitors' massive industrial facilities requiring hundreds of millions in funding.The company's measured approach to cost projections, deliberately avoiding the over-promising that has plagued the DAC industry, while still targeting dramatic improvements over current $600-1000 per tonne costs.Securing pre-seed funding led by Contrarian VC, known for rigorous DAC due diligence, and landing MilkyWire as their first commercial client despite being in early development stages.Their 2025-2030 roadmap: pilot testing in 2026, first commercial facility by 2029, and targeting megatonne-scale operations by 2030.How airlines could use their CO2 for e-fuel production, with potential applications ranging from direct air capture and storage to point source capture, leveraging the technology's versatility.The founders also discuss the challenges of being female entrepreneurs in a male-dominated deep tech sector, their base in central Paris near the Marie Curie museum, and their vision of normalising female-led climate tech companies by 2035.Larrazabal explains why the DAC industry is in its "innovation decade" similar to renewable energy in the 1960s-70s, and why they believe they've found the "solar PV moment" for carbon capture.Learn more about the innovators who are navigating the industry's challenges to make sustainable aviation a reality, in our new book 'Sustainability in the Air: Volume 2'.

In this episode, we speak with Luke Farajallah, CEO of Loganair, UK's largest regional airline that operates the world's shortest commercial flight and the only airline globally that lands commercially on a beach.Farajallah discusses:Loganair's unique "fishing in a big pond" approach to sustainable aviation, investing simultaneously in SAF, hybrid-electric aircraft with Heart Aerospace, and hydrogen propulsion with ZeroAvia rather than betting on a single technology.Why regional airlines are better positioned than major carriers to pioneer sustainable aviation, given their shorter routes, smaller aircraft, and wider technology options beyond expensive, imported sustainable aviation fuel.The company's mandatory £1 carbon offset programme included in every ticket, funding local environmental projects across Scotland through their Green Skies initiative, achieving near-zero customer resistance.Strategic partnerships, including equipping Embraer aircraft with 130kg water vapour sensors for the UK Met Office to study contrail environmental impacts, and plans for the world's first hydrogen-powered commercial flight from Orkney.As a leader who transformed Loganair's operational performance from 22nd to 2nd place in European rankings in just 12 months, Farajallah brings a results-driven approach to balancing commercial viability with environmental responsibility whilst serving communities that depend entirely on aviation connectivity.If you LOVED this episode, you'll also love the conversation we had with Sally Davey, CEO of Travelyst.

In this episode, we speak with Suzanne Neufang, CEO of the Global Business Travel Association (GBTA), who shares how the world’s leading business travel association is transforming corporate travel to accelerate aviation decarbonisation through industry collaboration.Neufang discusses:How sustainability priorities amongst travel managers more than doubled from 8% in 2023 to 19% in 2024, though the industry baseline remains at just 1.3 out of 5 on GBTA's sustainability maturity scale.Why sustainable aviation fuel (SAF) is the most promising decarbonisation pathway for aviation today, and how corporate customers must play an active role in stimulating market demand through SAF certificate purchases.How GBTA's Sustainability Acceleration Challenge mobilised over 240 companies to benchmark their decarbonisation efforts and identify best practices.Why GBTA takes a pragmatic rather than activist approach, focusing on harmonising standards across the complex corporate travel ecosystem to eliminate inefficiencies.How artificial intelligence holds great promise for optimising travel decisions and emissions tracking, with potential for 10-15% emissions reductions through more efficient air routing alone.Why business travel serves as a catalyst for broader aviation sustainability, given that corporate travellers are the frequent flyers responsible for most airline profits and emissions.Neufang also explains GBTA’s three-pronged strategy of bringing the industry together, rallying players around common standards, and building capacity at scale to move the entire travel industry towards more sustainable practices.If you LOVED this episode, you’ll also love the conversation we had with Sally Davey, CEO of Travalyst, who shares how the not-for-profit coalition is transforming the travel industry through collaborative data initiatives.

In this episode, we speak with Anders Forslund, Co-founder and CEO of Heart Aerospace, who shares the radical transformation his electric aircraft company has undergone in the past year — relocating from Sweden to Los Angeles and fundamentally changing how aerospace companies operate in the 21st century.Forslund discusses:Why Heart moved its operations to the US despite strong European roots, driven by the need to access customers, suppliers, and investors in the world’s largest aerospace market.How the industry’s talent crisis stems from decades without clean sheet aircraft development, and why bringing in top performers from SpaceX, Tesla, and other mission-driven technology companies is essential for attracting the right talent.Why all aerospace companies are actually software companies, given that most aircraft delays and crashes today stem from software issues rather than structural failures, and how this demands in-house control of software.Why companies should actively take on uncertainty rather than minimise it, viewing adaptability as more crucial than strength or intelligence in today’s rapidly changing world.How the loss of regional connectivity serves as the “canary in the coal mine” for broader industry problems, and why this represents the natural entry point for introducing new technology and training the next generation of aerospace talent.Forslund also reveals his seven-rule framework for modern aerospace product development and explains why focusing on building rather than predicting the future is the key to success.If you LOVED this episode, you’ll also love the conversation we had with Daniel Rosen Jacobson, Co-Founder & Co-CEO of Elysian Aircraft, who discusses the startup’s unique approach to electric aviation.
