In this episode of Exploring Clean Energy, Andy is joined by Hannah Monaghan, Boeing’s Australia Lead for Sustainability Reporting & Governance. Together they unpack aviation’s decarbonisation pathway, discussing everything from Hydrogen, SAF, Electric flight, aircraft design and operational efficiencies.

Hannah’s Highlights:

1:05 - Boeing in Australia & NZ: 98+ years, ~4,500 people, Melbourne composites, RAAF sustainment
3:50 - Why decarbonise aviation: ~2% of emissions today, APAC demand set to grow
6:15 - Boeing’s pillars: fleet renewal, advanced tech, operational efficiency, renewable energy, market measures
9:40 - Aircraft lifecycles (30–40 yrs) and retrofits: winglets, 787 curved wings, 777X folding tips
13:20 - Certification reality: safety testing - why it takes time
15:30 - Ops efficiency wins: smarter arrivals, single-engine taxi, collaboration with airports & ATC
18:10 – Carbon offsets to removals: CORSIA basics, first ocean-based removals MOU; green hydrogen by-product
21:05 - SAF 101: drop-in fuel, HEFA pathway, feedstocks (UCO, ag residues, MSW)
24:30 - Where SAF is today: blends to 50% certified across Boeing fleet; pathway to 100%
27:10 - Supply, policy & refineries: keeping feedstock onshore; AU & NZ outlooks
31:00 - Turnarounds & infrastructure: why SAF fits current refuelling ops; blending mandates
33:40 - Electric & hydrogen: use-cases, grid “greenness”, long-haul constraints for Australia
38:10 - Cascade 2.0: open modelling to test SAF, hydrogen, electric and grid scenarios
41:20 - Materials & circularity: composites, cabin “one-percenters” (lightweight recycled carpets)
44:30 - Barriers & opportunities: stackable incentives, global harmonisation, jobs & fuel security
48:10 - Final take: now is the moment - coordination across industry, government and communities
