Boeing has unveiled its 2022 ecoDemonstrator – a 777-200ER that will test around 30 new technologies aimed at improving sustainability and safety for the aerospace industry.

During six months of flight and ground tests starting this summer, the wide-body aircraft will be used to evaluate a water conservation system, vortex generators plus technologies to improve operational efficiency.

Net zero

“Boeing is committed to support our customers and enable the commercial aviation industry to meet our shared commitment to net zero carbon emissions by 2050,” said Stan Deal, Boeing Commercial Airplanes president and CEO.

“The ecoDemonstrator programme’s rigorous testing of new technologies further enhances the environmental performance of our products and services and is invaluable to continuously improving safety.”

Testing programme

The tests will include:

  1. In collaboration with NASA, SMART vortex generators – small vertical vanes on the wing – that improve aerodynamic efficiency during takeoff and landing
  2. A system to conserve onboard water and reduce weight as well as fuel use
  3. Additively manufactured aeroplane and engine parts to help reduce fuel use and manufacturing waste
  4. An environmentally preferred refrigerant and a new fire suppression agent to reduce greenhouse gas emissions
  5. A heads-up enhanced vision system for pilots to improve operational efficiency
  6. Continued comprehensive study of the impact of sustainable aviation fuel toward the reduction of emissions


For all flight tests, the 777-200ER will fly on the highest approved blend of sustainable aviation fuel (SAF) available.

“The Boeing ecoDemonstrator programme brings together the two most important ingredients to a more sustainable future – innovative technologies and partnerships with customers, suppliers, government agencies and academia,” said Chris Raymond, Boeing Chief Sustainability Officer.

“We celebrate the past successes and look forward to continuing this iconic programme to help decarbonise aviation, together.”
