Sustainability In The Air

In this episode, we speak with Paul Bloom, CEO of Gevo, who shares how low-carbon fuels, carbon capture, and technology are coming together to accelerate aviation’s path to net zero.
He discusses:
Why Gevo stepped away from the DOE loan guarantee: The DOE loan guarantee was always one of several potential financing options for Gevo. When enhanced oil recovery (EOR) for Gevo’s CO2 co-product became a requirement, the lack of oil and gas infrastructure in North Dakota made it difficult to secure a bankable offtake agreement. Gevo is now pursuing private credit and bank financing for its ATJ-30 project.
Carbon as a second product line: For every ton of fuel, Gevo also produces about a ton of CO2, which is sequestered and stored more than a mile underground. This helps cut the fuel’s carbon intensity by a little over 30 points, and the stored carbon also generates removal credits that Gevo sells to corporate buyers.
Tracking how the fuel was made: Gevo’s Verity platform uses distributed ledger technology to track inputs in the fuel production process, bringing transparency, traceability, and trust to the fuel’s entire carbon story.
The case for regional SAF supply: Rising jet fuel prices and the global availability of carbohydrate feedstocks strengthen the case for regional supply of SAF. Bloom views ATJ-30 as the first in a series of modular plants that could be deployed across regional markets to meet the rising fuel demand.

In this episode, recorded at the Farnborough Airshow 2026, we speak with Christoph Pereira, CEO of Software as a Service (SaaS), Aerospace Carbon Solutions and Sustainability at GE Aerospace, about how one of the world’s largest engine maker is using software, data and hybrid electric propulsion to decarbonise aviation.
He discusses:
Why GE Aerospace runs a software business alongside its engine franchise, and how software focused on safety, efficiency and resilience can leverage more capacity from constrained airspace immediately.
How GE Aerospace, NASA and BETA Technologies demonstrated hybrid-electric propulsion at 30,000 feet aboard a modified Saab aircraft.
How the collaboration with BETA, struck less than a year earlier, put a jointly developed turbogenerator on display in BETA’s autonomous MV250 eVTOL at the Farnborough Airshow. The vehicle offers a longer range, higher speed and much lower cost than traditional helicopters.
How tools like SIGNPOST help airlines with environmental compliance at the lowest marginal cost, whilst DecisionX delivers aviation-specific weather insight on contrails, icing and turbulence.
How GE Aerospace’s FLIGHT DECK manages a 20-year engine development cycle alongside six-month software builds.
If you LOVED this episode, you’ll also love the conversation we had with Kyle Clark, Founder and CEO of BETA Technologies, who shares the realities of bringing electric aircraft into operation. Check it out here.

In this episode, we speak with Julia Silvis, Managing Director of Research and Intelligence at the GREATER MSP Partnership, the economic development partnership for the Minneapolis Saint Paul (MSP) region region that built and leads the Minnesota sustainable aviation fuel (SAF) Hub, a first-of-its-kind coalition working across the entire SAF value chain from feedstock to the airport fuel supply.
She discusses:
Working supply and demand together: How the Minnesota SAF Hub’s defining feature is that it operates on both sides (supply and demand) of the market, giving it visibility into bottlenecks before any individual producer runs into them.
How Delta Air Lines brought SAF to an economic development group: The story of Delta approaching GREATER MSP after its 10% SAF by 2030 commitment, and how interest from Xcel Energy, Cargill and Ecolab convinced the organisation there was something worth building.
Getting the first truckload from camelina to wing: The three-month effort that moved SAF made from local winter camelina to MSP airport, and what it taught the hub about blending capacity, infrastructure and trust.
Horizons, not just a billion-gallon goal: Why the Hub’s has set a target of 1 billion of SAF by 2050, and why it has been broken into three gradual “horizons”: ongoing uplift at MSP, in-state production by around 2030, and multiple pathways by 2035.
Defending regional hubs and asking for federal stability: Why Silvis believes building things in the real world is harder at the federal level, how regional hubs customise rather than duplicate, and why policy consistency over 10-15 years matters more to producers than any single credit.
If you LOVED this episode, you’ll also love the conversation we had with Bruce Fleming, CEO of Montana Renewables, who shares how one of the largest SAF producers scaled its operations by leveraging existing infrastructure rather than starting from scratch. Check it out here.

In this episode, we speak with Jan Petter Steinland, Director of Strategic Analysis and Transformation at the Civil Aviation Authority Norway, about how the administrative body is building an ecosystem for electric and hybrid aviation.
Steinland discusses:
Why a regulator is leading, not an airline: How CAA Norway and Avinor built the test arena without a launch customer, arguing that backing one airline would narrow the field before anyone knows which technologies will succeed.
Learnings from 126 electric flights: BETA Technologies and Bristow Norway ran a trial for electric flights for six months between Stavanger and Bergen.
The real charging challenge: Turnaround time is mostly a question of charging power, but consecutive charging heats batteries over a long operating day. Steinland believes global standardisation on battery cooling approaches are needed as varying solutions at every airport are unlikely to scale.
Norway’s SAF mandate: How Norway set the world’s first blending mandate starting at 0.5%, to prove that blending could be regulated, reported and followed up.
Norway’s international test arena for zero‑ and low‑emission aviation: How agreed learning objectives and an open, cross-industry scope set the test arena apart from a closed environment built around one manufacturer.
