New paper on the role of direct air carbon capture in decarbonising aviation

The latest MaREI at University College Cork paper led by Nathan Gray in collaboration with colleagues at Queen’s University Belfast and the University of Galway examines whether we can reach net zero in aviation through the use of Sustainable Aviation Fuel and the role of Direct Air Carbon Capture. 


  • Premium seating is responsible for up to 4 times more emissions than economy.
  • E-fuels use twice as much energy as direct air carbon capture and storage.

  • E-fuels cause 9.8 times more emissions for a given electricity emissions intensity.

  • Direct air carbon capture and storage has lower abatement cost compared to e-fuels.

  • Decarbonisation could add up to €3813 to the price of an airline ticket.
