A hybrid capacitive storage system and method for storing electrical energy and hydrogen comprising at least a first dielectric layer, which dielectric layer is substantially impermeable to hydrogen. The hybrid storage system further comprises at least a first catalytic electrode layer disposed on at least a portion of a first surface of said first dielectric layer, which first catalytic electrode layer converts molecular hydrogen into atomic hydrogen, an electrode layer disposed on at least a portion of a second surface of said first dielectric layer, which electrode layer is selectively electrically connected to said first catalytic electrode layer; and at least one field generator for selectively applying a field to said storage system. Upon introduction of hydrogen to the storage system and activation of the at least one field generator, the hydrogen is converted to protons and electrons, wherein the electrons are permitted to flow through electrical connection to the electrode layer and the protons remain at the first catalytic electrode layer.

System and method for storing hydrogen and electrical energy

Disclosed herein is a hydrogen storage composition comprising a catalyst composition disposed upon a storage composition; wherein the catalyst composition comprises an alloy of calcium, barium, platinum, palladium, nickel, titanium, chromium, manganese, iron, cobalt, copper, silicon, germanium, rhodium, rhodium, ruthenium, molybdenum, niobium, zirconium, yttrium, barium, lanthanum, hafnium, tungsten, rhenium, osmium, iridium, or a combination comprising at least one of the foregoing metals.

Compositions and methods for hydrogen storage and recovery

Disclosed herein is a method for the storage of hydrogen comprising contacting a hydrogen storage composition with a gaseous mixture comprising hydrogen; and irradiating the hydrogen storage composition with radio frequency radiation or microwave radiation in an amount effective to facilitate the absorption, adsorption and/or chemisorption of hydrogen into the hydrogen storage composition.

Devices and methods for hydrogen storage and generation

A method for determining past-service conditions and/or remaining useful life of a component of a combustion engine and/or a thermal barrier coating ('TBC') of the component comprises providing a photoluminescent ('PL') material in the TBC, directing an exciting radiation at the TBC, measuring the intensity of a characteristic peak in the emission spectrum of the PL material, and correlating the intensity of the characteristic peak or another quantity derived therefrom to an amount of a new phase that has been formed as a result of the exposure of the component to extreme temperatures. An apparatus for carrying out the method comprises a radiation source that provides the exciting radiation to the TBC, a radiation detector for detecting radiation emitted by the PL material, and means for relating a characteristic of the emission spectrum of the PL material to the amount of the new phase in the TBC, thereby inferring the past-service conditions or the remaining useful life of the component.

Thermal barrier coatings, components, method and apparatus for determining past-service conditions and remaining life thereof

An apparatus for determining past-service conditions and/or remaining useful life of a component of a combustion engine and/or a thermal barrier coating (&ldquo;TBC&rdquo;) of the component comprises a radiation source that provides the exciting radiation to the TBC to excite a photoluminescent (&ldquo;PL&rdquo;) material contained therein, a radiation detector for detecting radiation emitted by the PL material, and means for relating a characteristic of an emission spectrum of the PL material to the amount of a crystalline phase in the TBC, thereby inferring the past-service conditions or the remaining useful life of the component or the TBC.
