Abstract
THREE THERMAL ENERGY STORAGE ALTERNATIVES--METAL HYDRIDES, PLASTIC CRYSTALS AND LIQUID AIR, WILL BE EVALUATED UNDER THE UNIQUE CIRCUMSTANCES OF SILENT WATCH OPERATIONS IN A COMBAT VEHICLE. HYDRIDES ARE COMPACT BECAUSE OF LARGE HEATS OF HYDROGEN SORPTION AND HIGH DENSITY. PLASTIC CRYSTALS ARE THE SIMPLEST ALTERNATIVE, WITH THE ADVANTAGES OF HYDRATED SALTS, BUT WITHOUT THE PROBLEMS OF SEPARATION OR CORROSION. LIQUID AIR, PRODUCED ON-BOARD BY A MINIATURE LIQUEFIER, REQUIRES LESS INSIDE SPACE THAN ANY OTHER ALTERNATIVE. LIQUID AIR IS STORED IN A CRYOGENIC VESSEL OUTSIDE AND VAPORIZED BY A COMPACT HEAT EXCHANGER INSIDE. REALISTIC COMPARISONS AMONG THERMAL ENERGY STORAGE ALTERNATIVES WILL CONSIDER THE ENTIRE SYSTEM, NOT JUST THE PHASE CHANGE MATERIALS. THE CONTAINERS FOR VARIOUS MATERIALS ARE SIGNIFICANTLY DIFFERENT--SOME ARE PRESSURE VESSELS, SOME ARE INSULATED, SOME MUST COPE WITH VOLUME CHANGES. HEAT EXCHANGER REQUIREMENTS ARE DEPENDENT ON MATERIALS PROPERTIES, CONTAINER TYPE AND THE TEMPERATURE OF THE PHASE CHANGE. THE RESEARCH TEAM INCLUDES SPECIALISTS FROM EACH OF THE THREE FIELDS. THEIR EXPERIENCE, WITH GUIDANCE FROM THE ARMY,WILL BE USED TO CHARACTERIZE THREE HEAT STORAGE ALTERNATIVES FROM COMBAT VEHICLES.
