With the Air Transport Action Group (ATAG) having committed to reducing 50% of its CO2 emissions by 2050, and the European Union’s Green Deal to become carbon neutral in the same period, the aviation industry is facing severe challenges to fulfil these ambitious goals.
In light of recent developments within the aviation sector and initiatives to reduce aviation’s climate impact, we are taking a closer look at what is happening within aviation in terms of climate sustainability.
Aircraft manufacturer Airbus has revealed three new concepts for zero-emission commercial aircraft, all based on hydrogen as a primary power source. These concepts include a long-haul option as well as two short-haul options. 
It is already well established that liquid hydrogen is used as a rocket propellant <https://www.nasa.gov/topics/technology/hydrogen/hydrogen_fuel_of_choice...., which was first initiated by NASA, the U.S. space agency. One chief reason for choosing liquid hydrogen in the first place was that it burns with extreme density while having the lowest molecular weight. So why is it that the commercial aviation industry is only now developing concepts for hydrogen use?

Obviously for these to be truly zero-emission (or even low emission), we'll need to build out a LOT of green hydrogen capacity that isn't there today. Until then, it's just a shifting of where in the supply chain towards aviation that the emissions take place.

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.

If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
