Extra heat in a closed cycle power generation system, such as a reversible closed Brayton cycle system, may be dissipated between discharge and charge cycles. An extra cooling heat exchanger may be added on the discharge cycle and disposed between a cold side heat exchanger and a compressor inlet. Additionally or alternatively, a cold thermal storage medium passing through the cold side heat exchanger may be allowed to heat up to a higher temperature during the discharge cycle than is needed on input to the charge cycle and the excess heat then dissipated to the atmosphere.

A solar thermochemical processing system is disclosed. The system includes a first unit operation for receiving concentrated solar energy. Heat from the solar energy is used to drive the first unit operation. The first unit operation also receives a first set of reactants and produces a first set of products. A second unit operation receives the first set of products from the first unit operation and produces a second set of products. A third unit operation receives heat from the second unit operation to produce a portion of the first set of reactants.

A system for the generation of electrical power using a solar collector that heats water using solar energy. The heated water is stored in a first tank. A vessel is connected to the first tank through a pipe and includes a headspace within which the heated water is sprayed to thereby generate steam. The headspace pressure is lower than atmospheric pressure and the water not converted to steam is collected in a pool at the bottom of the vessel to be fed back into the first tank. The steam is fed to a partial admission turbine that drives an electrical generator.

Systems and methods relating to use of external air for inventory control of a closed thermodynamic cycle system or energy storage system, such as a reversible Brayton cycle system, are disclosed. A method may involve, in a closed cycle system operating in a power generation mode, circulating a working fluid may through a closed cycle fluid path. The closed cycle fluid path may include a high pressure leg and a low pressure leg. The method may further involve in response to a demand for increased power generation, compressing and dehumidifying environmental air. And the method may involve injecting the compressed and dehumidified environmental air into the low pressure leg.

In a clean boiler with steam conversion and hydrogen/oxygen pre-blending, the clean boiler comprises two identical boiler bodies integrated to form a single entity. The clean boiler comprises two slim cavities, four water-containing chambers and four combustors, which is heated at wide faces and generates steams rapidly. The boiler comprises an integrate body containing two independent boiler bodies (1), and each of the independent boiler bodies (1) contains an independent boiler chamber (19). A steam conversion and transformation system is simultaneously provided for introducing a part of steam into the independent boiler chamber (19). High temperature of the boiler chamber (19) is utilized to promote a decomposition of the steam into H.sub.2 and O.sub.2. Water formed by H.sub.2 and O.sub.2 is utilized as a fuel to provide a self-sustaining combustion and heating, thus reducing a dependence on a primary energy source, reducing carbon emissions and protecting the environment.

The present invention provides an infrared hydrogen/oxygen combustor. The structure of the combustor includes a sinus ring (1). A surrounding foot (12) of the angle-shaped sinus ring (1) wraps a material-containing basin (14). A first small tube (16) and a second small tube (7) are connected the material-containing basin (14) and the angle-shaped sinus ring (1). Water solution (3) is contained in the material-containing basin (14). A straight-hole ceramic water-absorbing board (5) is provided on the upper part of the water solution (3), a spacing ring (6) is provided above the side of the material-containing basin (14) and in the upward ring of the angle-shaped sinus ring (1), a two-stage material-containing box (9) with a separated brake is provide on one side of the angle-shaped sinus ring (1). The technical scheme of the invention reduces the production cost, the pollution and protects the environment.

A multi-fuel microgrid class generator system includes a heat regenerative steam engine that provides a versatile power source having a clean burn using liquid fuel or biomass for generating electricity. The generator system is also capable of using wind energy and/or solar energy that is converted to heat and stored in a thermal storage unit using a heat exchange medium, such as carbon/graphite. The heat regenerative steam engine uses these various power sources to generate up to 1 megawatt of clean and cost-effective electricity.
