Parker Meggitt Develops Energy Buffer for Airbus's Hydrogen Fuel Cell Propulsion System

The company aims to have a prototype of its eBuffer system ready to start ground testing in 2023, and another unit ready for flight testing in 2025 with the chosen ZeroE demonstrator aircraft.

Parker Meggitt has joined Airbus’s ZeroE program team, working on plans to bring a hydrogen-powered airliner into commercial service by 2035. The aerospace group this week announced that it is developing an energy buffer system to be part of the energy storage equipment in the propulsion system for Airbus’s planned demonstrator aircraft.

According to a January 12 statement by Parker Meggitt, the system it calls the eBuffer “will maximize safety, efficiency, and weight while balancing electric and mechanical constraints,” describing the unit as an energy storage system that will use superconductor technology to deliver energy much quicker than a standard battery.
