To fly 2,000 miles with hydrogen, a 747 jet would need to allocate half its available space for gas and on-board mechanisms needed to turn it into power, completely changing the economics of air travel.
Hydrogen has almost three times the energy density of jet fuel, but requires four times as much space to provide the same amount of energy. The technical challenges of storing and transporting hydrogen are complex and expensive.
Our Sustainable Aviation fuel can drop into existing planes and fueling infrastructure to make carbon neutral air travel a reality today, saving trillions of dollars in potential fleet and infrastructure changes.
