Hydrogen peroxide (H2O2) is an excellent way to store oxygen. It is infinitely miscible with water to produce easily handled solutions that are liquid from below 0 °C to above 100 °C. A liter of 50 wt% H2O2 contains as much available O2 as a cylinder of gas at a pressure of 2,860 psia, while a 90 wt% solution is equivalent to a pressure of 6,000 psia. Current systems for catalytically decomposing H2O2 are effective, but cannot start rapidly enough to efficiently supply a system operating in a pulsed mode, especially at low temperatures, without consuming either large amounts of electrical energy or a constant flow of peroxide. This system will use a flash heated catalyst bed to initiate both thermal and catalytic decomposition and quickly supply oxygen. It also includes a low thermal mass catalyst bed that quickly heats to operating temperature and carries out the continuing catalyses. The flash heating system operates for only a short time and is recharged using only a small power draw.
