dc.description.abstract | New and improved energy storage technologies are required to overcome
non-dispatchability, which is the main challenge for the successful integration of large
shares of renewable energy within energy supply systems. Energy storage is proposed to
tackle daily variations on the demand side, i.e., storing low-price energy during off-peak
or valley periods for utilization during peak periods. Regarding electrical energy storage,
several technologies are available with different potentials for scalability, density, and
cost. A recent approach for grid-scale applications is based on transcritical carbon
dioxide charge and discharge cycles in combination with thermal energy storage systems.
This alternative to pumped-hydro and compressed air energy storage has been discussed
in scientific literature, where different configurations have been proposed and their
efficiency and costs calculated. The potential of the concept has been demonstrated to be
an economical alternative, including hybrid concepts with solar thermal storage. Even at
low temperatures, the addition of solar energy has proved to be cost effective. This paper
explores the effect of introducing solar-based high temperature heat on the performance
of different configurations of “Transcritical carbon dioxide ‒ thermal energy storage
system” cycles. A base-cycle with 8-hour discharge time is compared with different
layouts. Discussions include details on the models, parametric analyses -including solar
technology alternatives-, and simulation results. Round trip efficiency of the base case,
without solar support and at pressure ratio of 9.4, is 52%. When solar input is considered,
the efficiency is above 60%, increasing the turbine inlet temperature to 950 K. Estimated
levelized cost of electricity values are in the range of pumped hydro and compressed air
energy storage, 90-140 USD/MWh in agreement with other works on this thermal storage
technology. The global analysis shows clear advantages for advancing in the study and
definition of this technology for exploitation of synergies at different power ranges,
integrated with mid/high temperature solar power plants and with smaller-scale
renewable installations. | es |
