ESS Inc. will deliver its iron flow battery solution to Amsterdam Airport Schiphol, in first quarter 2023. The Energy Warehouse will be used in a pilot to enable the retirement of polluting diesel generators in the future as part of Schiphol Airport's ambitious sustainability plan. Schiphol is to be a zero-waste and emission-free airport in 2030.

A pilot will be carried out with the Energy Warehouse to recharge Electric Ground Power Units (E-GPU). E-GPUs are batteries which will replace the diesel ground power units currently used to supply electrical power to aircraft when parked at the airport. ESS' solution was selected for its superior environmental and safety performance - ESS' safe and nontoxic iron flow batteries pose no fire or explosion risk which makes them safe for use in close proximity to passenger aircraft.
