The concept of cloud energy storage provides a new idea and platform for the scale application of consumer-side energy storage. To further study the role of cloud energy storage in business, we improve the optimization clearing model of cloud energy storage on the basis of benefit analysis.

It is widely admitted that energy storage technologies will play an important role in the transition of the power generation sector towards more sustainability [1], [10]. A new energy storage concept has been developed by
The resulting storage device should be lighter and smaller, and hopefully cheaper, than one that only makes profit of sensible energy changes. Tanks filled with encapsulated PCM are being studied as a form of thermal storage devices.
The storage NPV in terms of kWh has to factor in degradation, round-trip efficiency, lifetime, and all the non-ideal factors of the battery. The combination of these factors is simply the storage discount rate. The financial NPV in financial terms has to include the storage NPV, inflation, rising energy prices, and cost of debt.

The research of an alternative energy storage solution and the need for new energy vectors has led the LAES to gain momentum in the research field during the last decade. A study on the recent trends of the research on LAES was conducted by Borri et al. [9] through a bibliometric analysis.] through a bibliometric analysis.
Three new energy storage concepts are introduced which are particularly suitable for delivering steady power from cyclic power sources, and specially from pulsed fusion reactors. These are: (1) PCM: Primary Coolant Mixing, (2) DCS: Diverted Coolant Storage, and (3) DCRS: Diverted Coolant Reversible Storage. The PCM concept is suitable for
The economic and financial performance for GIES and non-GIES are comparable. The Monte Carlo analysis shows that the LCOE values for GIES and non-GIES are 0.05 £/kWh - 0.12 £/kWh and 0.07 £/kWh - 0.11 £/kWh, respectively, for a 100 MW wind power generator and 100 MWh energy storage.
For the former two energy storage can defer the investment in production or transmission capacity, whereas for the latter storage lowers charges by utilities for periodical demand peaks. The literature on energy storage frequently includes "renewable integration" or "generation firming" as applications for storage ( Eyer and
