A method for controlling the generation of hydrogen gas from a metal borohydride solution with organic pigment catalysts
A comparably priced but more active catalyst in the process to solidify hydrogen that overcomes its significant barrier to automotive adoption is a move toward sustainability, environmental protection, and energy independence. Storing hydrogen safely and efficiently must be accomplished before it can be a widespread, mainstay fuel source, because it is a gas in standard conditions.
Based on the simple molecular gas H2, this domestic and environmentally “green” fuel must be stored on-board a vehicle in heavy, pressurized cylinders that are difficult to carry as a supply when traveling relatively far. When stored as a solid, hydrogen could overthrow refined petroleum fuel as the source to power the market of over 1 billion cars worldwide. A route to overcoming this, by converting H2 to its solid state, relies significantly on catalysts in the process of H2 generation from a borohydride solution. Conventional catalysts are often inorganic metallic powders that are not as active as a newly invented organic catalyst that offers a higher rate of hydrogen generation at a comparable cost.
A method using the organic pigment catalyst, the critical aspect of this technology, calls for immersing the catalyst in borohydride solution for a controllable rate of on-board hydrogen gas generation for fuel cells or combustion engines, primarily in vehicles. These catalysts accelerate the reaction by acting as an oxidizing agent toward the borohydride ion and a reducing agent of the production of hydrogen. With this type of catalyst, H2 generation from a borohydride solution can be accomplished with readily available materials, versatility, reliability, and accuracy. The new way of hydrogen release enables accurate and economical material and fuel consumption.
