How far hydrogen should build interdependence with other programmes – as it continues its rapid and often singularly focused evolution – was a hot topic today at the EU Hydrogen Week.
Axel Krein, Executive Director at Clean Aviation, said the aviation industry has quadrupled in the last 30 years and emissions have reduced by a factor of two.
“This is not sustainable so our challenge is to develop technologies to make aviation climate neutral by 2050, which means we need to have our technologies ready by 2028, and the new products are ready to enter the market by 2035,” he said. “Technology development is one thing, but we will also be working on sustainable aviation fuels (SAFs) and everything relating to hydrogen.”
Latest estimates show that hydrogen combustion could reduce the climate impact of flight by 50-75% (depending on the extent of non-CO2 effects), and hydrogen-based fuel-cell electric propulsion by 75-90%.
