Systems and generating power in an organic Rankine cycle (ORC) operation to supply electrical power. In embodiments, an inlet temperature of a flow of gas from a source to an ORC unit may be determined. The source may connect to a main pipeline. The main pipeline may connect to a supply pipeline. The supply pipeline may connect to the ORC unit thereby to allow gas to flow from the source to the ORC unit. Heat from the flow of gas may cause the ORC unit to generate electrical power. The outlet temperature of the flow of the gas from the ORC unit to a return pipe may be determined. A bypass valve, positioned on a bypass pipeline connecting the supply pipeline to the return pipeline, may be adjusted to a position sufficient to maintain temperature of the flow of gas above a threshold based on the inlet and outlet temperature.

A system is provided that draws heat from an open-loop engine cycle into a closed-loop working fluid circulatory system that utilizes computer-aided feedback mechanisms. The closed-loop working fluid draws engine heat from multiple sources: exhaust stack gases, the engine block, the engine transmission, and the engine headers and exhaust manifold near the valves. Heat exchangers are arranged in an ascending pattern according to the temperature of the heat at each heat generating location of the open-loop engine cycle. A wankel or similar type engine receives the heated working fluid and rotates a shaft connected to a generator to generate electricity. An electrolysis unit is powered by the generated electricity and separates water into hydrogen and oxygen. A reformation unit receives fuel such as diesel and the generated hydrogen to reform the fuel prior to injection into the engine for combustion. Oxygen from hydrolysis is combined with ambient air to increase combustion efficiency and reduce harmful emissions.

This invention relates to a method of operating an engine and, particularly to a method of determining the pressure of a working gas within a Stirling engine of a domestic combined heat and power unit relative to a pre-defined pressure. The present invention provides a method of determining the pressure of a gas within an engine relative to a pre-defined pressure of the gas, comprising measuring the power factor of electricity generated by the engine, comparing the measured power factor with a power factor determined to correspond to the power factor of electricity generated by the engine when operating at the pre-defined pressure and determining whether the measured power factor is less than the determined power factor. Variations in measured power factors may also be used to indicate faults in the engine.
