Despite challenges in the commercial aviation sector, hydrogen remains a potentially disruptive energy carrier and transportation fuel, particularly in decarbonisation scenarios. Aviation is responsible for between 2%-3% of global emissions, and most of the abatement has come from blending biofuels into the existing blend. Could hydrogen play a bigger role in aviation? How does the current economic crisis, which has decimated the aviation industry, factor into current research and trends? Jeffrey McDonald speaks with Dr. Anita Sengupta from Airspace Experience Technologies and Roel van Benthem from Royal Netherlands Aerospace Centre to discuss these questions and more.
