Title: High performance metal hydride based thermal energy storage systems for concentrating solar power

Abstract

Thermal energy storage (TES) systems based on metal hydride pairs using new class of high efficiency materials are evaluated. The use of low temperature metal cost effective material such hydrides NaAlH4 and Na3AlH6 became possible. In order to obtain high efficiency at reasonable cost high temperature materials were altered by the addition of materials to form reversible alloys and hydrides. The compounds were cycled to determine stability of hydrogen capacity over extended number of cycling. A thermal energy storage system based on two metal hydride pairs such as CaAl/CaH2/Al:NaAlH4, Ca2Si/CaH2/Si:Na3AlH6 and NaMgH2F—Si/Mg2Si—NaF:Na3AlH6 allows low cost and high efficiency performance.

Metal hydride-based thermal energy storage systems

Patent Vajo, John J.; Fang, Zhigang

The invention provides a thermal energy storage system comprising a metal-containing first material with a thermal energy storage density of about 1300 kJ/kg to about 2200 kJ/kg based on hydrogenation; a metal-containing second material with a thermal energy storage density of about 200 kJ/kg to about 1000 kJ/kg based on hydrogenation; and a hydrogen conduit for reversibly transporting hydrogen between the first material and the second material. At a temperature of 20.degree. C. and in 1 hour, at least 90% of the metal is converted to the hydride. At a temperature of 0.degree. C. and in 1 hour, at leastmore »« less

Systems and methods for randomized, packet-based power management of conditionally-controlled loads and bi-directional distributed energy storage systems

Patent Frolik, Jeff; Hines, Paul; Almassalkhi, Mads

The present disclosure provides a distributed and anonymous approach to demand response of an electricity system. The approach conceptualizes energy consumption and production of distributed-energy resources (DERs) via discrete energy packets that are coordinated by a cyber computing entity that grants or denies energy packet requests from the DERs. The approach leverages a condition of a DER, which is particularly useful for (1) thermostatically-controlled loads, (2) non-thermostatic conditionally-controlled loads, and (3) bi-directional distributed energy storage systems. In a first aspect of the present approach, each DER independently requests the authority to switch on for a fixed amount of time (i.e.,more »« less

Thermal energy storage and power generation systems and methods

Patent Ambrosini, Andrea; Miller, James E.; Gill, David D.

A solar power system and materials capable of storing heat energy by thermochemical energy storage are disclosed. Thermal energy is stored as chemical potential in these materials through a reversible reduction-oxidation reaction. Thermal energy from concentrated sunlight drives a highly endothermic reduction reaction that liberates lattice oxygen from the oxide to form O.sub.2 gas, leaving energy-rich, oxygen-depleted particles. When desired, the heat is recovered as the particles are re-oxidized in an exothermic reaction upon exposure to air. The system may be integrated with a power generation system to generate power.
