MITIGATING HYDROGEN FLUX THROUGH SOLID AND LIQUID BARRIER MATERIALS

摘要

Enhanced containment, capture, transfer, and storage of hydrogen gas in sealed enclosures is achieved using multi-layered materials comprising polymer(s), metal(s), metal alloy(s) and/or metal oxide(s) that either form, line, or coat the wall(s) of the sealed enclosures. These composite materials decrease "loss" of hydrogen gas by combining equilibrium and kinetic barriers to hydrogen diffusion. Capture and separation of gaseous hydrogen permeating through the wall(s) of an enclosure is accomplished by trapping the gas in either one or more internal liquid layers, or in one or more attached, gas-tight covers. Tightly packed sets of sealed enclosures, especially pipes or tubes with one or more polymer/metal ± metal oxide/liquid layers or interlayers can be placed in hydrogen "warehouses" and/or "silos" to provide seasonally firmed supplies of hydrogen gas to local or city-gate markets.
