Press release, 6 May 2021

From today, flights on the route between the Danish cities Sonderborg and Copenhagen will use sustainable aviation fuel (SAF). Alsie Express is the first operator of a domestic route in Denmark to use aviation fuel made from sustainably sourced, renewable waste and residue raw materials, helping to reduce the carbon emissions of its flights.


When flight no. 6I101 takes off from Sonderborg Airport for Copenhagen, its passengers and crew will be taking part in the beginning of the transition to a sustainable domestic aviation industry in Denmark. As first-mover in the domestic flights market, the airline Alsie Express has launched a collaboration with Sonderborg Airport and Danfoss, among others, to introduce sustainable aviation fuel (SAF) into its operations.


The flight marks the first step towards a future where domestic flights will gradually reduce their emissions as the use of SAF increases. The SAF will be used in blended form and is made from sustainably sourced, renewable waste and residue raw materials. In its neat form, and over the lifecycle of its use, it reduces CO2 lifecycle emissions by up to 80% compared to fossil jet fuels.[1]


“So far, air traffic here in Denmark has primarily only been able to offer offsetting arrangements in relation to emissions. However, with the introduction of sustainable jet fuel, we can target our efforts on reducing flight emissions. This initiative is small but very important step in the right direction towards reducing the CO2 emissions from our flights, ”states Dennis Rybatch, CEO Alsie Express.


Sonderborg Airport services passengers from all of southern Denmark, including business travelers. The Airport’s voluntary initiative has been brought about by its objective to reduce the carbon footprint of flights and at the same time lead the way for more sustainable domestic flights in Denmark.


First step towards net-zero emission

According to Ulrik V. Brendstrup, DCC & Shell Aviation Denmark CEO, the Sonderborg Airport initiative sets a fine example for how air traffic in Denmark can start using SAF in the years to come.


“In cooperation with Alsie Express and Sonderborg Airport, we are making important progress towards more sustainable air transport. These are small, but important steps, helping to place sustainable aviation fuel on the agenda in Denmark. While Power-to-Liquids and hydrogen offer exciting prospects for decarbonising aviation in the future, sustainable aviation fuel is a solution that is available to reduce aviation emissions today,” he explains.


The SAF is being supplied by DCC & Shell Aviation, the current supplier of jet fuel to Danish airports, as part of Shell Aviation’s SAF supply agreement with Neste.[2] In future, DCC & Shell Aviation are also exploring opportunities to supply Danish airports and airlines with SAF made from Danish sewage sludge through the HTL project in Aalborg.[3]


“We’re proud to be working with Shell Aviation Denmark A/S and Alsie Express, supporting this important milestone for decarbonising air travel in Denmark,” commented Adam Harrison, General Manager, Shell Aviation Europe and Africa. “Sustainable Aviation Fuel is crucial to the Aviation Industry reaching net zero emissions, alongside new technologies and carbon offsetting. Today’s announcement is a great example of how the domestic aviation sector can play an important role in building demand as the fuel industry seeks to increase supply of SAF.”
