Disclosed is a mixed composition fuel produced after the combustion of hydrogen and oxygen. The mixed composition fuel produced after the combustion of hydrogen and oxygen is prepared by a process in which secondary combustion gas pyrolyzed in a steam injection-heat storage unit is mixed with a fuel in which water vapor is mixed with a water electrolysis gas. In particular, this process includes: a first step for preparing the mixed composition fuel in which the secondary combustion gas pyrolyzed in the steam injection-heat storage unit is mixed with the fuel in which water electrolysis gas and water vapor are mixed; and a second step for using combustion equipment to combust the mixed composition fuel in which the secondary combustion gas pyrolyzed in the steam injection-heat storage unit is mixed with the fuel in which water electrolysis gas and water vapor are mixed. Therefore, the present invention can solve the problem inherent in technology for improving combustion efficiency and reducing pollutants wherein the amount of water electrolysis gas that can be mixed and combusted is significantly limited because flame temperature increases when water vapor is not mixed.

A method by which an environmental energy (e.g., wave energy) is harvested, converted into electrical power, and thereafter used to electrolyze seawater into hydrogen and chlorine gases. Those gases are recombined into hydrogen chloride from which is formed hydrochloric acid solution which is diluted and deposited at a depth sufficient to ensure its neutralization and sequestration for a significant period of time (e.g., for over a millennium). By removing chloride ions from a portion of the sea adjacent to its upper surface and depositing them into a portion of the sea more adjacent to its bottom, acidity is shifted from the surface to base of the sea, and the surface ocean is given a greater ability to absorb and buffer atmospheric carbon dioxide without a corresponding increase in acidity.

A system and method for producing hydrogen (H2) gas and a magnesium (Mg)-aluminum (Al) based aqueous suspension from pre-prepared effervescent tablets are provided. The produced H2 gas can be stored in a tank or directly utilized in a fuel cell, whereas the produced suspension can be employed as an advanced heat transfer fluid in a variety of thermal applications. Furthermore, the as-prepared tablets are fabricated with a homogeneously mixed and well-compressed mixture of Al particles, Mg particles, and sodium bicarbonate (NaHCO3) powder in a sealed container to prevent air and humidity from reacting with the raw materials. As a result of the chemical reaction between the tablet and water, H2 gas (in the form of bubbles) and the Mg—Al-based suspension are produced simultaneously. This system results in two products (i.e., H2 and suspension) that can be used individually or all at once by integrating the different system components together.

An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.
