Schiphol Tests World-First Super Battery to Revolutionize Ground Operations

In a groundbreaking move towards sustainability, Schiphol Airport has introduced an Iron Flow Battery, a world-first in airport energy storage, aiming to enhance the electrification of ground equipment and alleviate pressure on the power grid.

Innovative Energy Solution

Arrival of the Iron Flow Battery

Recently installed on the A/B apron, the Iron Flow Battery will undergo extensive testing over the coming months. This large battery provides a reliable power supply for charging electrical equipment, including electric Ground Power Units (e-GPUs). The e-GPUs deliver power to parked planes at locations lacking fixed electricity, allowing aircraft auxiliary engines to remain off and thereby improving air quality and reducing noise on the apron.

Environmentally Friendly and Safe Technology

Natural Components for Sustainability

The Iron Flow Battery stands out for its use of natural components, employing iron and salt water instead of the more common lithium. These materials are abundant, environmentally friendly, and fire-safe, with the battery's capacity remaining constant for up to 20 years.

Enhanced Quality of Work

Sybren Hahn, Executive Director of Infrastructure at Schiphol, expressed pride in the innovation, stating, "The Iron Flow Battery is a great example of how we as an airport want to lead the way with innovative infrastructure that improves the quality of work."

Development and Collaboration

Partnerships and Funding

Developed by ESS Inc. in Oregon, USA, the battery technology was brought to Schiphol by the airport's innovation team. Volker Infra and KES manage and utilize the battery, which is partially subsidized by the EU as part of the TULIPS program. This European collaboration, led by the Royal Schiphol Group and involving 32 aviation parties and knowledge institutes, aims to accelerate sustainable innovations in airports.

Future Prospects

If the trial is successful, Schiphol plans to deploy more Iron Flow Batteries, with the goal of making all ground equipment emission-free and electric. This initiative aligns with Schiphol’s ambition to achieve emission-free and waste-free operations by 2030 and become energy positive by 2050.
