Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. This technique can be used to make hydrogen gas, a key component of hydrogen fuel, and breathable oxygen gas, or can mix the two into oxyhydrogen - also usable as fuel, though more volatile and dangerous.
System and process for producing synthetic liquid hydrocarbon
ActiveUS20080115415A1Improve carbon efficiencyReduce area requirementsMuffle furnacesCarbon compoundsOxygenElectrolysis of water
Production of synthetic liquid hydrocarbon fuel from carbon containing moieties such as biomass, coal, methane, naphtha as a carbon source and hydrogen from a carbon-free energy source is disclosed. The biomass can be fed to a gasifier along with hydrogen, oxygen, steam and recycled carbon dioxide. The synthesis gas from the gasifier exhaust is sent to a liquid hydrocarbon conversion reactor to form liquid hydrocarbon molecules. Unreacted CO & H2 can be recycled to the gasifier along with CO2 from the liquid hydrocarbon conversion reactor system. Hydrogen can be obtained from electrolysis of water, thermo-chemical cycles or directly by using energy from carbon-free energy sources.

Solid polymer fuel cell with improved voltage reversal tolerance
In a solid polymer fuel cell series, various circumstances can result in the fuel cell being driven into voltage reversal. For instance, cell voltage reversal can occur if that cell receives an inadequate supply of fuel (for example, fuel starvation). In order to pass current during fuel starvation, reactions other than fuel oxidation may take place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter may result in significant degradation of the anode. Such fuel cells can be made more tolerant to cell reversal by promoting water electrolysis over anode component oxidation at the anode. This can be accomplished by incorporating a catalyst composition at the anode to promote the water electrolysis reaction, in addition to the typical anode electrocatalyst for promoting fuel oxidation.

A method for producing methanol and dimethyl ether using the air as the sole source of materials is disclosed. The invention relates to a method for separating the water (i.e., the moisture in the air) and carbon dioxide content of atmospheric air for their use in the subsequent production of methanol, dimethyl ether and derived synthetic hydrocarbons as products. The method includes the conversion of carbon dioxide and water under conditions sufficient to produce methanol and / or dimethyl ether. Methanol and / or dimethyl ether can be used as fuel or fuel additives or further converted to synthetic hydrocarbons and their products. Carbon dioxide is captured on a suitable absorbent, preferentially polyethyleneimine supported on nano-structured fumed silica. The process can also involve hydrogenation with hydrogen produced by electrolysis of water obtained from the air or from any other water source. Methanol can be dehydrated to produce dimethyl ether or further processed to produce synthetic hydrocarbons, polymers, and products derived from them by other known methods.

Hydrogen Generator
InactiveUS20080302670A1Risk of explosion can be minimizedSimple processHydrogenOxygen/ozone/oxide/hydroxideElectricityCombustion chamber
A generator produces variable output of hydrogen and oxygen from electrolysis of water as a fuel supplement for combustion of hydrocarbon fuel. The generator includes an electrolytic reactor having a sealed cathode chamber partially filled with an electrolyte solution, and an anode immersed within the solution and electrically isolated from the chamber. A level sensor and reservoir maintain solution levels in one or more reactors configured in electrolyte communication. A source of electrical power energizes reactors responsive to changing combustion demand. A cooling system cools the reactors to allow the generator to operate at high amperage. An optional controller shifts reactor duty cycles to equalize reactor service over time. Gases produced in reactor air space above solution level are drawn or pumped to a combustion chamber to combine with hydrocarbon fuel and air. The combination results in greater combustion efficiency and reduces harmful emissions.

Gimbal-mounted hydroelectric turbine
InactiveUS6956300B2Reduce environmental impactPositive net energyFluid couplingsWind energy with electric storageFluid intakeEngineering
A power plant extracts energy from a free flowing motive fluid by means of a turbine mounted on a gimbal. The shroud element of the fluid intake has external rudders, in conjunction with the gimbal mounting, enabling the enclosed turbine to instantaneously respond to changes in the direction of the free flowing motive fluid thus ensuring the face area of the intake is always physically orthogonal to the direction of the motive fluid streamlines. The shroud element may also be buoyant so as to optimally extract energy from an upper non-turbulent and higher velocity layer of the free flowing motive fluid. To function within an inherently unsteady source of energy, the preferred embodiment of the turbine is coupled to a DC generator which may further be coupled to a voltage and current regulating circuit which either charges a battery, performs electrolysis of water to produce hydrogen fuel, or is further coupled to a DC motor coupled to an AC generator. Alternatively an AC induction generator may be coupled to the turbine. Other mechanical, electrical, electronic, or electromechanical features may optionally be implemented to perform such tasks as adaptively locating the turbine in the maximum velocity flow, adapting internal vane and runner blade pitches for various flow rates and loads, keeping the intake free of obstructions, preventing loss of aquatic life, controlling and communicating the state of charge of the battery, or gauging and controlling the electrolysis process and communicating the fullness of the hydrogen gas output tanks.
