Once certified and ready to fly, Sirius will lease 10 hydrogen VTOL jets to PARQ for use in Bali and the surrounding islands at a cost of $65,000 per month.

MEHAIR is looking to operate zero-emissions aircraft on regional routes between land and water infrastructure and has ordered 50 Sirius Millennium Jets with an option for a further 50 units.

Sirius Aviation has debuted a hydrogen powertrain with Sauber F1 and global automotive giant BMW Group Designworks. Technologies from the automotive industry can speed up development of this HVTOL project.
