Honeywell partners with National Renewable Energy Lab

Honeywell will provide technological expertise, testing for fuel cartridge technology, supply chain support, prototyping and fuel cell evaluation to qualify for the 'Fuel Additives for Solid Hydrogen (FLASH) Carriers in Electric Aviation' project.

The FLASH project will mature a new hydrogen carrier technology developed at NREL as part of the Hydrogen Materials Advanced Research Consortium (HyMARC) project. The programme is funded by a partnership of the DOE's Hydrogen and Fuel Cell Technologies Office, NREL, and Honeywell.

Electric UAVs are seeing rapid adoption in industrial applications such as surveying, infrastructure inspection and security. Many of these applications previously required inefficient ground-based vehicles or hazardous use of piloted helicopters.

For short-range applications, UAVs have the potential to offer greater efficiency, reliability and precision compared with conventional combustion-driven aircraft. For long-range and heavy-payload applications, however, battery-powered electric UAVs today fall short. The NREL and Honeywell collaboration seeks to prove that hydrogen can help address these longer-duration, high-payload challenges.

"Today's long-range drones are typically powered by internal combustion engines. While they provide the required range that battery-powered electric UAVs lack, these engines have issues with excessive noise, vibration and emissions, including carbon emissions," said Katherine Hurst, NREL senior scientist and group manager. "This is an exciting opportunity to demonstrate the performance of hydrogen storage materials that we developed in our laboratory together with Honeywell to fuel a real-life flying vehicle."

The FLASH project seeks to deliver an alternative approach in which efficient and long-lasting hydrogen storage is coupled to a fuel cell that converts hydrogen to electricity to power electric UAV flight. The resulting system will enable long-range flights, but without the noise and tail-pipe emissions of combustion engines. It will also enable sensitive drone applications like atmospheric monitoring, where exhaust gases and rumbling engines would reduce performance.
