Systems and methods to utilize heat carriers in conversion of thermal energy

A system for converting thermal energy to electrical power, the system comprising:

• a closed-loop thermal cycle device including:
• an evaporator including a first fluid path to accept and output a flow of heated fluid and a second fluid path to accept and output a flow of a working fluid and configured to indirectly transfer heat from the flow of heated fluid to the flow of the working fluid to cause the working fluid to change phases from a liquid to a vapor,
• an expander to generate electrical power via rotation by vapor state working fluid,
• a condenser to cool the flow of the working fluid to cause the working fluid to condense to the liquid,
• a pump to transport the liquid state working fluid from the condenser for heating,
• a loop for the flow of the working fluid defined by a successive fluid path through the evaporator, the expander, the condenser, and the pump, and
• an injection point positioned between the pump and the evaporator;
• and
• an amount of heat carrier injected into the loop via the injection point such that the amount of heat carrier flows in the successive fluid path and configured to adsorb and desorb the working fluid and, upon desorption and adsorption respectively, generate additional heat to increase output of electrical power.
