摘要： 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.

摘要： The present disclosure relates to thermochemical heat storage units. The teachings thereof may be embodied in systems and methods for operating, including charging and discharging, a thermochemical heat storage unit. For example, a method for operating a thermochemical heat storage unit may include: producing a first steam and feeding it to a heat exchanger; partially condensing the steam with release of its thermal energy, in the heat exchanger; subsequently pressurizing water condensed from the steam; feeding the pressurized water to the heat exchanger; evaporating the water into a second steam; and storing at least a portion of the second steam in a steam storage unit.

摘要： A heat exchange system with at least two heat exchange chambers is provided. Each of the heat exchange chambers includes heat exchange chamber boundaries which surround at least one heat exchange chamber interior of the heat exchange chamber. The heat exchange chamber boundaries include at least one first opening for guiding in of an inflow of at least one heat transfer fluid into the heat exchange chamber interior and at least one second opening for guiding out of an outflow of the heat transfer fluid out of the heat exchange chamber interior. At least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange flow of the heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the heat transfer fluid.

摘要： Thermochemical energy storage (TCES) for concentrating solar power (CSP) systems provides higher energy density than sensible energy storage systems. An ammonia-based TCES system dissociates endothermically into hydrogen and nitrogen. The stored energy is released when supercritical hydrogen and nitrogen react exothermically to synthesize ammonia. Prior ammonia synthesis systems are unable to produce temperatures consistent with modern power blocks requiring a working fluid, for example steam or carbon dioxide, to be heated to greater than 600° C., for example about 650° C. An ammonia synthesis system heats steam from, for example 350° C. to 650° C. under pressure of about 26 MPa. The hydrogen and nitrogen are preheated with a flow of supercritical fluid prior to the synthesis step to provide reaction rates sufficient to heat power block working fluid to the desired temperature.
