  • Episode featuring Tong Douglas / Etihad

    Enjoyed the podcast and the very clear learning’s from Etihad’s experiment and approach. The Conscious Choices program appeared innovative and one that may act as a benchmark for other aviation companies to emulate. Well done !

Talking Points

Recent interactions between the hosts and their guests.

From geothermal to green jet fuel: How Iceland could become aviation’s SAF bridge
Q: Why shift from hydrogen export to SAF production?
The SAF path enables commercial-scale production and a price dynamic that can be achieved at scale in Iceland, while ensuring demand through local and eventual export opportunities, and it aligns with broader decarbonization goals.
How Copenhagen Airports is navigating the complexity of aviation decarbonisation
Q: Can you share details about the Alight project and what learnings you've gathered that could help other airports?
Alight is a five-year EU project led by Copenhagen Airport focused on sustainable aviation, sustainable airport operation, and smart energy, delivering a replication toolbox, battery energy storage, and learnings on safety, energy management, and integration with other assets for broader adoption by other airports.
How Copenhagen Airports is navigating the complexity of aviation decarbonisation
Q: How does Copenhagen Airport interact with SAF, ESAF, and other future fuels given you don't own the fuel farm or control supply?
CPH treats SAF variants as an integrated part of operations but does not own the fuel farm; it acts as a connector, data provider, and facilitator across the value chain. They highlight financing gaps for ESAF, the need for long-term off-take agreements, and the airport's role in enabling pilots and partnerships rather than direct procurement.
How Copenhagen Airports is navigating the complexity of aviation decarbonisation
Q: What is Copenhagen Airport's approach towards sustainability and aviation, and what targets are you pursuing for Scope 1 and 2?
The airport is targeting net zero for Scope 1 and 2 by 2030 and expects to reach it before then, while developing a Scope 3 plan driven by external activities. They emphasize electrification and direct operational improvements for Scope 1/2, and collaborative, long-term strategies for Scope 3 through partnerships and R&D across the value chain.
Why Firefly Green Fuels believes waste could decarbonise aviation
Q: What are the main economic levers that could drive cost parity with conventional fuels?
Key levers include consistent feedstock gate fees (reduction of disposal costs), cost-effective downstream hydro-treatment, and credible long-term off-take contracts. If gate fees remain favorable and the offtake is bankable, fuel costs could approach parity with conventional fuels within a decade, aided by incentives.
