JAL Rolls Out Its First Lithium-Ion Battery-Powered Ground Power Unit

Japan Airlines unveiled the lithium-ion battery-powered ground power unit, known as the “eGPU,” at Matsuyama Airport.

This marks JAL’s inaugural utilization of this innovative technology aimed at curtailing CO2 emissions and noise pollution. While aircraft typically rely on an auxiliary power unit (APU) for electricity and air conditioning when parked, these units emit substantial exhaust gases, including carbon dioxide (CO2), and noise.

In a bid to address environmental concerns at airports and minimize aviation fuel consumption during downtime, diesel engine-powered ground power units (GPU) have conventionally provided electric power and air conditioning.

The introduction of the “eGPU” promises to slash CO2 emissions to zero and reduce noise levels by approximately 30% (below 65db) compared to conventional methods. This advancement is poised to enhance the working conditions for operators, mitigate noise and environmental issues surrounding airports, and bolster global environmental preservation efforts.

Manufactured by ITW GSE, the “eGPU” units can sustainably supply electricity for approximately 14 flights during the turnaround time of a Boeing 737-800 aircraft on a full charge and have seen deployment in over 400 units globally.

JAL has been actively exploring the integration of “eGPU” units at domestic airports as part of its commitment to promoting CO2 emission reduction in airport facilities and vehicles, as advocated by the Civil Aviation Bureau of the Ministry of Land, Infrastructure, Transport, and Tourism.

This initiative is anticipated to pave the way for broader deployments at other airports, leveraging insights gained from this initial implementation. Both JAL and TAS remain steadfast in their dedication to advancing global environmental preservation efforts and fostering a more sustainable aviation industry.
