The government announced its CO2 reduction target for 2020. The target represents a 30% reduction from the estimated level of 2020. This goal is deemed very challenging since Korean industry had doubled its greenhouse gas emissions between 1990 and 2005, the fastest growth in the OECD. Korea has voluntarily set its 2020 emission reduction target. With this pledge, Seoul seeks to be a model for other countries including China and India who are catego. [pdf]

One of the numerous TES technologies that is garnering a lot of attention is reversible latent heat storage based on phase change materials (PCMs), which offers the advantages of high energy storage density and small temperature swings. (1,2) Over the past few decades, researchers have developed three generations of PCMs with an enthalpy range from 50 J/g to 400 J/g, ranging from plastic crystals to molten salts. (3−6) Their properties have been promoted for applications in photo-thermal conversion, electro-thermal conversion, and thermal management. (2−4) Due to the inherent benefit of latent heat capacity, the thermal storage density of PCMs makes them one of the highest technologies among thermal storage systems. [pdf]

Grid energy storage (also called large-scale energy storage) is a collection of methods used for on a large scale within an . Electrical energy is stored during times when electricity is plentiful and inexpensive (especially from sources such as and ) or when demand is low, and later returned to the grid. We developed an engineering-economic model for each of the four energy storage technologies; each is modeled with its own set of operational and cost parameters, including round trip efficiency, energy capacity, fixed operating cost, capital cost, and expected duration of capital investment.

Energy Storage Systems play an essential role in modern grids by considering the need for the power systems modernization and energy transition to a decarbonized grid that involves more renewable sources.
Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
As discussed in the earlier sections, some features are preferred when deploying energy storage systems in microgrids. These include energy density, power density, lifespan, safety, commercial availability, and financial/ technical feasibility. Lead-acid batteries have lower energy and power densities than other electrochemical devices.
With regard to the off-grid operation, the energy storage system has considerable importance in the microgrid. The ESS mainly provides frequency regulation, backup power and resilience features.
First, our results suggest to industry and grid planners that the cost-effective duration for storage is closely tied to the grid’s generation mix. Solar-dominant grids tend to need 6-to-8-h storage while wind-dominant grids have a greater need for 10-to-20-h storage.
