1. A plant for producing a mechanical energy from a carrier fluid under cryogenic conditions, comprising:
a cryogenic tank configured for storing said carrier fluid under said cryogenic conditions;
a capacitive tank;
a supply circuit, connecting said cryogenic tank to said capacitive tank and comprising a pump, configured to increase a pressure of said carrier fluid, and a main heat exchanger, arranged downstream of said pump and configured to promote a thermal exchange between a thermal source and said carrier fluid to increase a temperature of said carrier fluid and evaporate said carrier fluid;
an engine body, configured for producing said mechanical energy and comprising at least one work chamber having an inlet port, arranged in fluid communication with said capacitive tank, and an outlet port connected to a discharge circuit for spent carrier fluid spent from the at least one work chamber;
a recirculation circuit configured to convey a portion of said carrier fluid spent from the at least one work chamber into said capacitive tank;
wherein the plant is in an open cycle configuration.
