1. A turbine engine assembly comprising:
a compressor section where a core airflow is compressed; a combustor section where the compressed core airflow from the compressor section is mixed with fuel and ignited to generate an exhaust gas flow;
a turbine section including at least two turbine stages through which the exhaust gas flow expands to generate a mechanical power output;
a condenser assembly where water is extracted from the exhaust gas flow exhausted from the turbine section;
a water storage tank where extracted water from the condenser assembly is stored;
a cooling system associated with the water storage tank for maintaining water stored in the storage tank at a temperature within a predefined range;
a controller configured for operating the cooling system to maintain a water temperature within the predefined range; and
an evaporator system configured for generating a steam flow from at least a portion of water extracted by the condenser for injection into the core airflow.
