Despite these obstacles, Barrett asserted that regional airlines could start transitioning to hydrogen fuel cells, given the technology's readiness for short flights. Fortescue's Ongoing Commitment to Green Energy Fortescue Future Industries, an early investor in Universal Hydrogen, remains committed to its green energy projects despite the start-up's collapse. A Fortescue spokesperson commented, "There is still significant interest in our green energy initiatives and the potential of green hydrogen and its derivatives. We are proud to be advancing some of the world's first green energy projects, including our Arizona Hydrogen project in the United States and our Gladstone PEM50 project in Queensland, Australia." The Future of Hydrogen in Aviation While long-haul hydrogen-powered flights are still a long-term goal, the groundwork laid by Universal Hydrogen represents a significant step toward zero-emissions aviation.
