Posted by Air ProductsResponsive · Patents for licensing · United States

Summary of the technology

This product delivers hydrogen with an extra degree of safety directly to fuel-cells on-demand. New designs are enabled since this "Liquid-Carrier for Hydrogen" is stored in tanks of any shape. The economics of this system have been validated by DOE and is among the least expensive methods of high-volume hydrogen storage. When loaded with hydrogen from renewable sources this technology delivers a complete green solution since the carbon portions of the molecules are completely re-used. With a well-to-wheels efficiency comparable to gasoline or EVs, this technology can deliver world-class efficiency.

Description of the technology

This hydrogen storing liquid pours and stores with the convenience of liquid fuels and yet is as inflammable as wood. Storing as much hydrogen as liquified hydrogen itself, this technology enables products capable of delivering high-power and long run-times to portable electronics, specialty devices, wheelchairs, UAVs up to grid-scale energy storage.


Stores 6.8 weight percent of hydrogen Low-Cost, non-fuming liquid with no vapor pressure Classified as 'Combustable' (one level below flammable) Delivers 600:1 volume of hydrogen Long shelf-life Many Cycles without degradation
