Why airports should become energy innovation hubs, not just transport hubs

In this episode, we speak with Christina Cassotis, CEO of Pittsburgh International Airport (PIT), who shares her ambitious vision for transforming the airport into a sustainable aviation hub. Cassotis discusses Pittsburgh’s unique position and innovative approach to aviation sustainability. She highlights several key initiatives:PIT has achieved a remarkable milestone as the world’s first fully off-grid major airport. Through a public-private partnership, the airport commissioned a microgrid in 2021 that powers its entire operation. The airport is developing three SAF production pathways: alcohol-to-jet technology using ethanol, fugitive methane capture, and hydrothermal liquefaction converting organic waste to fuel.Their hydrogen strategy includes testing hydrogen-powered ground equipment like snowplows, developing distributed production technology, and establishing themselves as a regional hydrogen hub supporting both airport and public transportation needs.PIT leverages unique assets including its location above the Marcellus Shale natural gas deposit, existing fuel infrastructure with export capability, Carnegie Mellon University partnership, and the region’s energy innovation legacy.Opening in 2025, their new LEED Gold terminal features rainwater capture systems, recycled construction materials, and a design optimised for origin and destination traffic, reflecting their evolution from a former US Airways hub.Throughout the conversation, Cassotis emphasises the importance of taking incremental steps toward sustainability targets, sharing knowledge across the industry, and maintaining a balance between environmental protection and operational efficiency. Her vision extends beyond Pittsburgh, aiming to create a model that other airports can learn from and adapt. If you LOVED this episode, you’ll also love the conversation we had with Robb Etnyre, General Manager of Truckee Tahoe Airport.
