  • Patent number: 11975969
    Abstract: A molten carbonate fuel cell-powered system for capturing carbon dioxide produced by a steam methane reformer system. Tail gas from a pressure swing adsorption system is mixed with exhaust gas from the fuel cell anode, then pressurized and cooled to extract liquefied carbon dioxide. The residual low-CO2 gas is directed to an anode gas oxidizer, to the anode, to the reformer to be burned for fuel, and/or to the pressure swing adsorption system. Low-CO2 flue gas from the reformer can be vented to the atmosphere or directed to the anode gas oxidizer. Reduction in the amount of CO2 reaching the fuel cell allows the fuel cell to be sized according to the power demands of the system and eliminates the need to export additional power output.

  • Patent number: 11952273
    Abstract: We disclose herein a viable, cost efficient method for the instantaneous production of hydrogen gas. Hydrogen gas production is increased by utilizing solar and lunar energy. The hydrogen gas is generated spontaneously by the reaction of sodium hydroxide and aluminum as corrosion occurs, forming a layer of aluminum oxide upon the aluminum. This aluminum oxide layer prevents further reaction of sodium hydroxide and aluminum, and thus no more hydrogen gas is produced. Production of aluminum oxide can be bypassed by adding acetic acid or sodium acetate to the reaction. In this reaction the products are aluminum hydroxide and hydrogen gas. Thus, we disclose herein a method that prevents of the formation of aluminum oxide by the use of sodium acetate or acetic acid, the use of iron as a catalyst, and the enhancement of the reaction using natural light.
