Abstract: A combined cycle power generation and storage system is shown. A liquid air energy storage system uses excess power to liquefy air and stores it in a liquid state. A combustion engine produces power by combustion of a carbon-based fuel along with an exhaust stream containing carbon dioxide. A heat recovery system exchanges heat from the exhaust stream to air from the liquid air storage system, and thereby produce a cooled exhaust stream and heated air. An air expansion machine recovers power by expansion of heated air from the heat recovery system. A separation system separates carbon dioxide from ambient air prior to liquefaction during operation of the liquid air energy storage system, and separates carbon dioxide from the cooled exhaust stream during operation of the combustion engine prior to emission of the cooled exhaust stream to atmosphere.

Abstract: The invention relates to a method for operating an internal combustion engine, wherein the internal combustion engine includes at least one combustion chamber in which a fuel is at least partially burned with ambient air, an exhaust tract that is coupled to an outlet side of the at least one combustion chamber in a fluid communicating manner, wherein hydrogen is used as fuel for the internal combustion engine, wherein the internal combustion engine also has at least one NOx storage catalyst and an exhaust gas discharged from the at least one combustion chamber into the exhaust tract at least partially, preferably entirely, flows through the at least one NOx storage catalyst, wherein a lean hydrogen-air mixture is burned in the at least one combustion chamber in a first operating state, wherein the NOx storage catalyst is regenerated in a second operating state. In order to easily operate the internal combustion engine as a low-emissions system, a rich hydrogen-air mixture is burned in the at least one combustion chamber in the second operating state.
