A new publication from the European TULIPS programme demonstrates how circular construction can move from ambition to everyday practice within airport environments. Drawing on evidence from more than 350 sources and validated by industry practitioners, the framework bridges the gap between theory and implementation—providing practical guidance for embedding circularity across airport infrastructure projects

To be future proof, airports must prepare to charge diverse electric aircraft with varying voltage needs. This calls for smart, flexible solutions that avoid costly infrastructure upgrades. Within the TULIPS project, Work Package 2 therefore developed and tested a modular, voltage‑agnostic charging system designed for this future.

TULIPS has completed its third demo wave — delivering progress in sustainable airport operations, from modular charging and heat‑storage analysis to hydrogen technology and smarter passenger waste separation. With the programme now extended to 2026, we’re gearing up for new demos, including a hydrogen drone flight and SAF initiatives. A big thank you to all partners and contributors driving this work forward!

What if airports could operate with a fraction of today’s environmental impact—while becoming smarter, more efficient, and easier to manage? That vision is at the heart of the Circular Airports Workshop and the Circularity Tour at Oslo Airport, held on Wednesday, 26 November. The event was part of the second TULIPS Progress event and focused on transforming barriers into breakthroughs for a more circular future in aviation.

From 24 to 26 November, TULIPS partner Avinor hosted the second TULIPS Progress Event in Oslo. This edition focused on projects that had not yet taken centre stage during the previous event in Torino – from digital solutions for international greener travel and circularity to modular charging and Sustainable Aviation Fuel (SAF). The programme combined the Progress Event with deep-dive sessions led by Work Package (WP) leads, as well as the annual General Assembly and External Advisory Board meeting. The result? A wealth of knowledge, input, and inspiration.

On 24 November, Rotterdam The Hague Airport (RTHA) reached an important milestone: Robert Simons, Deputy Mayor of Rotterdam, officially opened a liquid hydrogen refuelling station at the airport. This facility, developed within the European TULIPS project, marks valuable progress towards sustainable aviation and reducing CO₂ emissions. The new facility is primarily designed for research purposes. It enables the dispensing of liquid hydrogen for research and development aircraft and drones.

At the IATA Ground Handling Conference (IGHC2025) from 13-15 May, TULIPS shared its latest insights into the potential of hydrogen-powered ground support equipment (GSE) at airports. In a dedicated session, experts from Fraunhofer IML, Royal Schiphol Group, and TLD explored both the opportunities and challenges of integrating hydrogen into airport ground operations.

Schiphol launches a pilot involving a specially developed aircraft tow vehicle and a prototype of a Toyota pick-up truck with an electric engine powered by hydrogen. Schiphol also has its own temporary hydrogen refueling station to supply these vehicles with hydrogen. The tow truck and refueling station are part of the EU funded TULIPS programme. With this pilot, the airport is taking an important step towards emission-free ground operations by 2030.
