Abstract
A compressed-air energy-storage system, comprising: a variable-nozzle expander configured to receive an airflow at a first pressure and partially expand said airflow at a second pressure, said second pressure being lower than said first pressure, expansion of said airflow in said variable-nozzle expander producing useful mechanical power; a heat generator component configured to receive a fuel and a partially expanded airflow from the variable-nozzle expander; and a turbine configured to receive combustion gas from the heat generator component and expand the combustion gas producing useful mechanical power.
