Easyjet has switched its green aviation plans from electric to hydrogen. The aim is now to be flying a 200 person plane by 2035 on hydrogen. Previously, they were working with wright electric on a battery electric plane by 2030.
Currently, aviation emits roughly 2.5% of carbon emissions, and when taking into account non carbon effects, it accounts for roughly 3.5% of human global warming effects.
They have hastened to add, that this does not mean that they are giving up on battery electric, but that they wish to have multiple options. It is also recognized, that at least in the short-term, that while battery electric might be able to replace 80% of easyjets flight paths, the rest are to far for battery electric, unless power density takes a bigger leap forwards than currently expected.
In the meantime, inefficient aircraft are gradually being replaced. Of course this is good both for the environment and the company, as an inefficient plane uses more fuel to fly.
