US aircraft maker Boeing unveiled its 2022 ecoDemonstrator plane that will be tasked with testing new technologies aimed at making air travel more sustainable and safer.
The ecoDemonstrator, a converted, 20-year-old 777-200ER, will undergo a six-month series of tests both on the ground and in the sky, starting this summer.
Those to reduce fuel use, emissions, and noise while incorporating more sustainable materials are among the 30 or so technologies set for testing projects.
Other projects include a system to conserve onboard greywater, which is water that is washed down the sink and used to flush toilets, which also reduces the aircraft’s weight.
The plane will also be used to test an environmentally friendly refrigerant, a new fire suppression agent that will reduce greenhouse gas emissions, and a pilot heads-up enhanced vision system that will improve operational efficiency.
The 777-200ER will be powered by a 30/70 blend of sustainable aviation fuel (SAF) and conventional jet fuel throughout its test period, according to Boeing.
