Quantum Fuel Systems Technologies Worldwide Inc. has been awarded a contract for expanded support of Lockheed Martin's Space Systems' development of the ISIS (Integrated Sensor is the Structure) airship powered by a regenerative fuel cell (RFC). Quantum will supply critical hydrogen metering systems in conjunction with the hydrogen and oxygen storage systems that it is currently supplying to Lockheed Martin. ISIS uses solar rays during daylight hours to generate renewable electricity that electrolyzes water to generate hydrogen and oxygen to run the RFC at night. Quantum has worked with Lockheed Martin to develop one of the lightest advanced carbon fiber composite hydrogen storage vessels in the world for this application. Lockheed Martin will build the prototype airship for DARPA under a $400 million contract.
