Environmental and Energy Benefits
The environmental benefits are many and can best be seen when looking at emissions data relevant to global climate change and local air quality.
Comparison for an Airbus A320 during 1 hour of ground time,
including main engine start, using 400Hz and Pre-Conditioned
Air either through the APU or through a GPSS (and APU for
main engine start). Does not include emissions of infrastructure
and energy production.
APU’s are among the most detrimental agents and make up
between 30 to 75 % of all handling associated emissions.
Potential CO2 and NOx reduction with GPSS operations, including emissions of infrastructure and energy production.
Potential Energy reduction with GPSS operations, including
infrastructure energy production.
