Abstract :
Thermal power transfer, water temperatures, and flow rates are calculated for HHP (hydrogen heat pump) units of 1000-kWh-thermal energy input per hour. The HHP uses feedwater at 200°C as the high-temperature input. An amount of heat amplified by a factor of 1.50 to 1.75 is returned to the feedwater line at an intermediate temperature. The amplification is a result of pumping heat from a low-temperature level, which produces cooling power. High COPs (coefficients of performance) are obtained if the intermediate-level heat outputs are used for heating and the low-temperature input is used for cooling. Metal hydrides of improved properties, as well as improved morphology of the reaction beds, are being constantly developed. Costs and economic estimates are given
