100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

Air Products is providing the hydrogen and fueling infrastructure for The Boeing Company’s Phantom Eye, a newly unveiled hydrogen-powered and unmanned airborne system demonstrator that is able to stay aloft at 65,000 feet for up to four days.

Phantom Eye will soon begin a series of ground and taxi tests at NASA’s Dryden Flight Research Center at Edwards Air Force Base, Calif. The aircraft is in preparation for its first flight in 2011, a debut flight expected to last between four and eight hours.

“Working with Boeing on this effort has been a privilege. It is always exciting and interesting to be associated with a cutting edge project, and the Phantom Eye certainly fits that category,” said Bob Kelly, business development manager–Hydrogen Energy Systems at Air Products. “Our approach to working on this project was to focus on our core competencies and values of safety first, and being mindful of the specific customer needs. Our engineering and design reviews were always very much aligned with that focus.”

Air Products and Boeing engineers worked closely to provide a cost effective and innovative fueling system capable of delivering liquid hydrogen to the vehicle. The hydrogen propulsion system has been described by Boeing as a key to Phantom Eye’s success, offering efficiency and great fuel economy, with water as its only byproduct, essentially making the plane a “green aircraft.”
