Abstract—In this work, a novel, simple and efficient power
storage system that provides both heat and electricity in high
efficiency is designed and proposed. The system works based on
a gas turbine cycle in which the input energy is supplied by a
thermal energy storage system instead of a combustion
chamber. The other key point is that heat production is as
important as power generation in this system. In order to prove
the proficiency of the system, it is comprehensively analyzed
thermodynamically in Denmark, regarding its power and heat
market regulations and historical data as the case study of this
work. The results show that an overall energy efficiency of
almost 85% and the electricity efficiency of 35% can be
expected for the system and it is demonstrated that the system is
highly feasible economically even taking conservative electricity
and heat prices into account.
