EAST HARTFORD, Conn., March 21, 2024 /PRNewswire/ -- Pratt & Whitney, an RTX (NYSE: RTX) business and the Federal Aviation Administration (FAA) will work together with Missouri University of Science and Technology (Missouri S&T), Aerodyne Research, Inc., and the Environmental Protection Agency (EPA) to study non- CO2 aviation emissions, to help understand and reduce the environmental impact of those emissions. As part of the FAA's ASCENT program, the project will measure emissions from a Pratt & Whitney GTF™ engine combustor rig test stand using conventional Jet A and 100% sustainable aviation fuel (SAF).

Key Points: 
  • As part of the FAA's ASCENT program, the project will measure emissions from a Pratt & Whitney GTF™ engine combustor rig test stand using conventional Jet A and 100% sustainable aviation fuel (SAF).
  • "As the aviation industry targets a goal of net-zero CO2 emissions by 2050, we continue to pay close attention to addressing the environmental impact of other emissions, including cruise non-volatile particulate matter and NOx," said Sean Bradshaw, senior technical fellow of sustainable propulsion at Pratt & Whitney.
  • The rig tests will take place at Pratt & Whitney's facility in Middletown, Conn., using an advanced Rich-Quench-Lean (RQL) combustor.
  • Pratt & Whitney, the FAA, Missouri S&T, Aerodyne Research, and the EPA will collaborate on test design, execution, and emissions data analysis.

Geoengineering may slow Greenland ice sheet loss

SAPPORO, Japan, Jan. 30, 2024 /PRNewswire/ -- One of the many effects of global warming is sea-level rise due to the melting and retreat of the Earth's ice sheets and glaciers as well as other sources. As the sea level rises, large areas of densely populated coastal land could ultimately become uninhabitable without extensive coastal modification. In order to stave off this possibility, carbon emissions need to reach net negative, a state that is hard to achieve under current circumstances.

Key Points: 
  • Hokkaido University researchers and colleagues show that stratospheric aerosol injection has the potential to reduce ice sheet loss due to climate change.
  • The simulations showed that SAI of sulfur dioxide would have a clear protective effect on the Greenland Ice Sheet.
  • Under RCP8.5, there would be ice loss equivalent to approximately 90 mm sea-level rise; under RCP4.5, ice loss would be approximately 60.6 mm sea-level rise; but under GeoMIP G4, ice loss would be limited to approximately just 37.6 mm sea-level rise.
  • "While this study shows that SAI could contribute to the protection of the Greenland Ice Sheet, and hence, potentially, all other ice cover on Earth, geoengineering is a highly contentious topic," Greve concludes.
