High-capacity, density and efficient hydrogen energy storage for automotive/portable applications
About
Background: This technology was developed to provide a highly efficient method for hydrogen storage to make energy storage on board of vehicle economically feasible.Conventional methods for hydrogen storage, such as compression and liquefaction, are not readily transferable to automotive or other portable applications. Improved hydrogen storage media and methods will enable greater use of alternative energy sources and reduce the reliance on hydrocarbon-based fuels. Andrei G. Fedorov from the School of Mechanical Engineering at Georgia Tech has developed a novel chemical storage system that provides reversible hydrogen storage and release at ultra-high capacity, density, speed, and ease, providing for low energy cost. The technology is based on a foldable polymer backbone that allows reversible uptake/storage/release of hydrogen fuel in response to thermal, chemical, mechanical, magnetic, electrical, or light stimuli. The storage system uses a natural or synthetic polymer with highly compact folding properties and chemically linked hydrogen-affine molecular complexes to provide an ultra-high surface area for hydrogen storage.
Key Benefits
Increased storage density: Backbone offers high surface area for hydrogen storage. Fast and easy: Polymer readily folds and unfolds for hydrogen storage and fast release in response to actuation. Suitable for packaging: Use compliant polymers as a matrix to assume any form factor.
