Projects at STR

Projects for sustainable mobility, development and climate protection at Stuttgart Airport.

STRzero

Our path to a climate-friendly airport

Stuttgart Airport has set itself a clear target: To reduce carbon dioxide emissions to an absolute minimum by 2040. To achieve this, the airport is pursuing its STRzero climate strategy - with a master plan for climate and energy at its centre.

The concept takes a holistic approach to climate protection. It covers the topics of energy efficiency, energy generation, smart grids, mobility and transport. The most important lever for reducing greenhouse gas emissions and achieving the climate targets is the systematic energy-efficient refurbishment of the company buildings. This includes, above all, the terminals, some of which have been in operation for over 30 years.

New legal requirements for energy efficiency and stricter standards for safety and fire protection also make it necessary to modernise the passenger buildings. This is why Flughafen Stuttgart GmbH is currently examining how the buildings can be renovated to maximise energy efficiency as part of the STRzero Terminal project.

Another focus: solar energy. The energy yield from solar energy is to be increased tenfold. The number of systems is to be increased from the current 7 to 32.

Stuttgart Airport is building an intelligent power grid so that the entire energy system can be operated efficiently and the self-generated electricity can be utilised optimally. It links generation, storage and consumption. The airport's vehicle fleet is also being further electrified. The charging infrastructure is also being expanded.

In this way, Stuttgart Airport is moving step by step towards STRzero - for more climate-friendly airport operations.

Project Goliat

Liquid hydrogen for the aviation of the future

How can aircraft be safely and reliably refuelled with liquid hydrogen (LH2) in the future? To answer this question and make aviation more sustainable, Airbus is working with stakeholders from research, industry and airport operations to advance the Goliat project . The aim is to develop and test safe and reliable procedures for handling LH2 at European airports.

The project is being funded by the EU's Horizon Europe initiative. Over the next 4 years, 10.8 million euros will be available for this purpose. Research and testing will take place at 3 locations in Europe: at the airports in Budapest, Rotterdam-The Hague and Stuttgart.

The project combines expertise from many areas. In addition to Airbus, 9 other partners from 8 countries are working together:

Chart Industries
Budapest Airport
Rotterdam The Hague Airport
Stuttgart Airport
H2FLY
Leibniz University Hanover
Royal Schiphol Group
TU Delft
VINCI Airports

This is how knowledge for the aviation of tomorrow is created together.

Stuttgart-Ulm railway project

Improved connection for the airport

Flughafen Stuttgart GmbH is contributing a total of 359 million euros to the Stuttgart-Ulm railway project. The airport is thus supporting a project that will significantly improve the accessibility and catchment area of the airport - especially in regional transport.

Of the total sum, 339.4 million euros will go to DB Netz AG as a financial subsidy. The airport is using a further 19.6 million euros to convert its own facilities.

The Stuttgart-Ulm rail project is thus strengthening the airport's connection to the region - for even better accessibility from all directions.

Sustainable Aviation Fuel

Sustainable Aviation Fuel (SAF) - sustainable paraffin - is a promising solution for more climate-friendly air transport. Compared to fossil fuel, SAF can reduce carbon dioxide emissions by up to 80 per cent. Stuttgart Airport is committed to advancing this development. Together with SkyNRG and Schwenk Zement, the airport is participating in a subsidised project of the state of Baden-Württemberg. The aim is to identify ways to improve SAF services in the state.

In order to support the use of the currently still expensive fuels, the airport is providing its own incentives: the airport is promoting the use of SAF by airlines with a subsidy totalling 500 thousand euros via the fee schedule. This actively supports the transition to more climate-friendly air transport.

Cloud cameras

For smarter energy management

Stuttgart Airport is focussing on renewable energies to achieve its climate targets. Solar power production on the airport site is to be increased tenfold by 2040. An intelligent energy system (smart grid) will help to balance out fluctuating yields - for example on very sunny or cloudy days.

An important component of this system: cloud cameras. They record the movements of the clouds every second and, together with other weather data, create precise forecasts of the expected solar power production at the airport. This enables energy management to plan better - for example, when it is best to charge electric vehicles.

For scientific purposes, 5 cloud cameras were temporarily distributed on the campus: 4 of them from Offenburg University of Applied Sciences, 1 from the Centre for Solar Energy and Hydrogen Research Baden-Württemberg.
