Abstract: A gas turbine is driven by combustion of a fuel which is a hydrocarbon oil-in-water emulsion. Successful operation is achieved with minimized corrosion of turbine blades by keeping the Na+ content of the emulsion to less than 1 ppm. Deionized water is generally to be used in making up the emulsion. Heavy oils can be used because their conversion to oil-in-water emulsion form makes them suited to the pre-atomization requirements of gas turbine combustion.

Abstract: A system of fuel use and fuel production comprising a vehicle, a source of liquid fuel, particularly methanol or a methanol/water mixture, means such as a methanol reformer for releasing hydrogen and carbon dioxide from the fuel, an engine such as an internal combustion engine or a fuel cell which is powered by the released hydrogen and means on the vehicle to store the released carbon dioxide. By converting the fuel into hydrogen and carbon dioxide and by providing a store for carbon dioxide on the vehicle, the present invention allows the carbon dioxide produced in the process of powering the vehicle to be collected and stored for later use in fuel production. Fuel production means are also provided.

Abstract: A system and method for the storage of electrical energy or of hydrogen, the method includes the steps of (a) electrolysis of water to yield hydrogen, (b) reaction of the hydrogen from step (a) with carbon dioxide to from at least one storage compound; (c) storage of the storage compound; and (d) subsequent conversion of the storage compound back to hydrogen or use of the storage compound to fuel an engine, such as an internal combustion engine, or to generate electricity directly or indirectly. One storage compound is methanol.
