Aviation to be electrical by 20250.

The Aviation is expected to be more electrical by 2050, but it will be a gradual transition:

Hydrogen and electric aircraft: Some say that hydrogen fuel cells could be used for mid-range flights, and hydrogen directly for long-haul operations by 2035. Others say that electric and hydrogen-powered planes are likely still decades away from large-scale application.

Battery-electric aircraft: Some say that battery-electric aircraft could have the lowest environmental impact of all forms of sustainable air travel by 2050. However, others say that the challenge for batteries is to pack in enough energy to replace jet fuel while remaining light enough.

Timeframe: Some say that to have a climate-neutral aircraft fleet by 2050, carbon-neutral aircraft need to be phased into the current fleet no later than 2035.

Collaboration: The Alliance for Zero-Emission Aviation (AZEA) is a voluntary initiative that aims to prepare the entry into commercial service of hydrogen-powered and electric aircrafts.

By 20250, battery-electric aircraft could have the lowest environment impact of all forms of sustainable air travel including flying on renewable fuels and hydrogen, according to a life cycle assessment conducted for Dutch electric aviation startup Elysian Aircraft.
