Sustainable aviation fuels and renewable energy for airport operation will enable a green transition.
More than 99 % of airline emissions and approximately 50 % of airport emissions are related to the combustion of jet fuel (skynrg.com). Further emissions are related to airport operation.
Upcoming fuels can reduce CO2 further
With electrofuels, from Power2X, it is possible to achieve further CO2 reduction.
In a longer term,
electric-powered aircraft, hydrogen fuel and hybrid versions could reduce CO2 further. Such propellants are being developed and will be involved in the project if applicable.
SAF based on sustainable resources
Sustainable aviation fuels could be based on household waste, wood residuals, used cooking oils and perhaps sustainable oil, and perhaps crops, or residues containing the necessary energy raw materials.
Sustainable, also referred to as advanced, fuels for aviation should use sustainable resources to produce a fuel that can substitute traditional jet fuel without using or harming food, biodiversity, forest- and water resources, humans or animals.
Reduction of NOx and particles
It is expected that the introduction of SAF and renewable energy will significantly reduce ultrafine particles and the concentration of NOx in and around the airport.
CO2 free renewable energy
Regarding energy for airport operation, electricity is the preferred sustainable and renewable energy carrier to take over from fossil energy.
Wind and solar energy
Electricity from wind turbines and Photovoltaic-systems is CO2 free energy at competitive prices. Electrification and energy storage is crucial when greening airport operations. Furthermore, incorporating flexible solutions reducing energy consumption and ensuring smart energy management will be implemented.
E-mobility both concerning passenger transport and ground handling equipment will reduce CO2 and other air pollutants immediately.
The goal is for transport to be emission-free by 2030 and for the entire airport to be emision-free by 2050.
CPH climate goals:
Be a green powered airport (using renewable energy)
Have lean, green and clean ground transport (fossile free equipment and transport)
Accelerate emission-free aviation
2030: Emission-free airport and ground transport
2050: Zero emission total airport operations
Sustainable aviation fuel will reduce CO2
Sustainable aviation fuel (SAF) is one of the key elements in achieving climate goals. SAF has the potential to reduce the overall carbon footprint up to 80 %.
Bio-kerosene (biofuel) will be used in ALIGHT and possibly also upcoming electrofuels or Power2X.
