Airbus is developing the ZEROe project to create a large, zero-emission, single-aisle passenger airliner powered by fuel cells using liquid hydrogen. The aircraft will utilize ultra-efficient motors with superconducting coils.

Airbus is currently ahead of Boeing in this technology sector. Although Airbus is committed to this initiative, hydrogen-powered aircraft are not expected to significantly affect the passenger aviation market until the late 2040s. In the electric vehicle sector, in-wheel hub motors are being pursued for their advantages like torque-vectoring, though challenges such as unsprung weight affecting ride quality remain.
