Thermal energy storage at the airport

There are 13 thermal energy storage systems (TES) at Schiphol Centrum and a few others at Schiphol Oost and Schiphol Noordwest. TES is a sustainable system that stores thermal energy underground. Most of the terminal, the majority of the piers and several offices run on thermal energy storage systems. Schiphol uses a lot less gas power to heat and cool these buildings as a result. This leads to significant gains in reducing our CO₂ emissions.

Thermal energy storage all over Schiphol

The new Pier A and piers B, D, E, F and G all have a TES system, as does the GH building. Terminal 3 starting using a large TES system in 2019 that saves 1.5 million m3 of natural gas per year (enough energy for 1000 households). Furthermore, the Hilton Hotel and various office buildings, including SHG, Avioport, WTC2 and the Base A-B-C-D, are fitted with modern TES installations with heat pumps and dry coolers. WTC1 will be equipped with a thermal energy system and heat pumps in 2021. It will be an entirely natural gas-free building, just like Pier A, Terminal 3 and the Base D.

What are the energy savings?

Thanks to, among other things, TES at Schiphol Centrum, the amount of natural gas consumed by our buildings has been almost halved from 11.8 million to 6.4 million m3 (2019) over the past ten years. That is equal to the amount of gas consumed by 3600 households. By making Pier D, Terminal 3 and the Base A-B-C more sustainable in 2020, a further 1.35 million m3 of natural gas was saved. That equates to the gas requirement of 900 households. A potential CO₂ emission reduction of 75-100% per building is an important step towards Schiphol’s ambition to be emission-free for our own buildings in 2030.

Off the gas grid

Our goal is for all of our airports’ own buildings to be off the gas grid by 2030. That’s why thermal energy storage systems will be installed in all newly-constructed buildings as of 2025. The installation of thermal energy and phasing out of gas in existing premises will be complete by 2030. We will only use gas when necessary at peak times. This gas will be 100% green.
