REVERSIBLE METAL HYDRIDE THERMAL ENERGY STORAGE SYSTEMS, DEVICES, AND PROCESS FOR HIGH TEMPERATURE APPLICATIONS

摘要

High-temperature thermal energy storage and retrieval systems, devices, and processes are described that reversibly store high temperature heat in metal hydride beds composed of titanium containing metals or transition metal alloy that reversibly form metal hydrides at high temperatures above about 600°C and at low temperatures at or below 100°C. The present invention provides exergetic efficiency up to 96% or better.
