One Group. One Story. One LinkedIn.
we are excited to announce our new sponsorship of CELLSIUS, a student initiative of ETH Zurich.
Starting in September, Montana Aerospace will support the team's Liquid H2 project, an ambitious initiative dedicated to developing a hydrogen-powered aircraft using liquid hydrogen technology.
Building on previous electric and gaseous hydrogen demonstrators, the students are now taking the next step towards a flight-capable liquid hydrogen propulsion system.
“For Montana Aerospace, this partnership is about more than supporting an exciting student project. It is an opportunity to engage with engineering experts of tomorrow, exchange ideas, and contribute our industry experience to a project exploring technologies that could help shape the future of sustainable aviation.
Collaborations like these strengthen the connection between academia and industry and demonstrate our commitment to innovation, engineering excellence and developing the next generation of aerospace professionals.
