Agnirva Space Premier League - Expedition #31014: Green Combustion in Space: The Italian Quest for Cleaner Air

The Italian Combustion Experiment for Green Air, developed by Dr. Patrizio Massoli and teams from the Istituto Motori and NASA Glenn Research Center, was an ambitious physical science study that took to the microgravity environment of the International Space Station (ISS) to refine combustion processes for cleaner air and energy efficiency.

Conducted during Expeditions 35/36 and 37/38, the experiment focused on how fuel particles burn in microgravity—a setting that eliminates convection and allows for clearer observation of flame behavior. On Earth, hot gases rise and cool gases sink, which distorts the way combustion can be analyzed. In space, those gravitational effects vanish, allowing researchers to isolate chemical phenomena.

The team investigated various fuel types and additives to understand how pollutants like soot and carbon monoxide form during combustion. The data collected helped define optimal combustion conditions that reduce harmful emissions.

The Italian Combustion Experiment employed advanced optical diagnostics to capture flame shapes, temperatures, and particulate formation. These precise measurements were impossible to achieve on Earth due to turbulence and gravity-driven airflow.

What made this project unique was its environmental mission. By studying combustion in a “pure” environment, the experiment generated cleaner models that could lead to the design of engines with drastically lower emissions. This has direct applications in designing green transportation technologies—especially for cars, planes, and power plants.

Moreover, the experiment contributed to international databases on flame chemistry, aiding scientists in creating more sustainable fuels and improving combustion efficiency across industries.

Beyond the technical benefits, this research underscores the value of space science in addressing terrestrial problems. Cleaner air, better engines, and energy efficiency aren’t just Earth goals—they’re planetary imperatives, and space research is accelerating their realization.
