A United Airlines passenger aircraft made history this week, as it completed a 984 km flight… powered 100% by renewable energy. How? SAF (sustainable aviation fuel) is fuel made by renewable biomass and “products generally discarded as waste”, says this article by Interesting Engineering. This fuel can be used directly by combustion engines, possible disrupting the energy industry.
This is a great moment for our planet. Worldwide, aviation produced 915 million tonnes of CO2 in 2019. More specifically, it produces around 2% of all human-induced carbon dioxide (CO2) emissions. This SAF-Powered flight produced 75% less carbon on the trip. In fact, aircraft maker Boeing said that “all its aircraft will use 100 percent SAF by the end of this decade.”
