1. A method of providing flexibly controlled production of mechanical or electrical power using a mixed refrigerant (MR), comprising:
splitting the MR into two components and independently storing a low-boiling point fluid (LBP) and a high-boiling point fluid (HBP);
using an initial heating source to fully or partially vaporize the LBP to a gas state;
feeding the LBP in the gas state to a let-down turbine to generate mechanical or electrical power; and
adjustably dosing the HBP to at least partially condense the LBP gas upon exit from the let-down turbine to a liquid or two phase state MR, and storing the MR in a storage vessel, and then performing the splitting again.
