Book & Claim for more sustainable air travel

Book & Claim for more sustainable air travel

St1_Airplanes_Gif_Final

Drive the energy transition together with us at St1!

The "Book & Claim" system is a new, certified way to reduce the climate impact from you and your colleagues when air travelling – even if the Sustainable Aviation Fuel (SAF) you purchase is not used directly on the specific flights you and your company book. SAF is produced in limited quantities and is difficult to distribute to every airport.

With "Book & Claim," companies can still contribute to the transition and report their climate efforts in a controlled and credible manner. The interest is rapidly growing! BRA, Norwegian, and the Norwegian Armed Forces are some of our customers already and we at St1 gladly welcome more! Do you also want to drive the energy transition?

Certified and reliable system

The system is certified by RSB (Roundtable on Sustainable Biomaterials), a global non-profit organization that works to promote the sustainable production and use of biofuels.

Questions & answers about SAF

Sustainable Aviation Fuel (SAF) is made from renewable raw materials. This means that the carbon dioxide released during combustion is part of the natural cycle, resulting in no net increase in CO₂. The fuels can also be produced from carbon dioxide and hydrogen from water via electrolysis with green electricity or biogas (electrofuels). Direct electricity and hydrogen are also future possibilities.

Aviation contributes to 3.5% of human climate impact. Like all sectors, aviation's carbon footprint must also decrease to slow global warming. Technological development and more sustainable fuels are essential to reduce CO₂ emissions. Thanks to the more efficient combustion of sustainable fuels, they also reduce fuel consumption and the occurrence of so-called high-altitude effects. Additionally, they prevent sulfur emissions.

SAF is made from raw materials that do not compete with food production or are environmentally harmful. Examples include algae, forestry waste, household waste, and slaughterhouse waste. Electrofuels require carbon dioxide and hydrogen from electrolysis with green electricity or steam reforming with biogas. Carbon dioxide is primarily sourced from biogenic point sources.

Today, the availability of SAF is limited and therefore much more expensive than fossil fuels. In Sweden, St1 has a biorefinery in Gothenburg that can produce about 70 kt of SAF per year.

There are seven approved techniques for making SAF. The allowed blending ratio varies with the technique used. At most, 50% of the fuel can consist of SAF, but tests conducted with 100% blending have shown good results without negative side effects on the engine or aircraft.

Today's aircraft fleet can be fueled with bio- and electrofuels without modification. For planes to be fueled with hydrogen or electricity in the future, new aircraft and new infrastructure are needed.

The EU has agreed on an overarching framework for the future of aviation, ReFuelEU Aviation. This includes a quota obligation starting with 2% blending of SAF in 2025, which is to increase to 70% by 2050.
