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.

摘要： A reservoir for containing a fluid includes a cylindrical wall sized to engage a shaft bored into ground, a bottom end cap fixed to a lower end of the cylindrical wall and a top end cap fixed to an upper end of the cylindrical wall. The top end cap is concave such that the top end cap extends below a top end of the cylindrical wall. The bottom end cap, the top end cap, and the cylindrical wall define a subterranean chamber. A plug made of a composite material is on the top end cap, with a lower face disposed on the concave top end cap and a peripheral face engaging the shaft. At least one pressure port extends downwardly into the shaft and through the plug and the top end cap, defining a fluid path to the subterranean chamber.
