ASPI CLIMATE ACTION BRIEF SOUTH KOREA
South Korea s energy storage solar power generation
With Korea aiming to achieve 20% renewable energy by 2030, energy storage systems (ESS) have become the nation’s secret sauce for balancing solar spikes and wind lulls. As of 2025, Korea’s ESS market has grown by 34% annually since 2020, fueled by tech giants like LG and Samsung SDI [4] [10]. [pdf]
South Korea s low-carbon energy storage system
The Korea Institute of Machinery and Materials (KIMM), under the National Research Council of Science and Technology (NST), has successfully developed and demonstrated key technologies for a Liquid Air Energy Storage (LAES) system—recognized as a next-generation solution for large-scale, long-duration energy storage. [pdf]FAQS about South Korea s low-carbon energy storage system
What is energy storage system (ESS) in South Korea?
Energy storage system (ESS) can mediate the smart distribution of local energy to reduce the overall carbon footprint in the environment. South Korea is actively involved in the integration of ESS into renewable energy development. This perspective highlights the research and development status of ESS in South Korea.
Are South Korean companies investing in energy storage systems?
Less than a decade ago, South Korean companies held over half of the global energy storage system (ESS) market with the rushed promise of helping secure a more sustainable energy future. However, a string of ESS-related fires and a lack of infrastructure had dampened investments in this market.
What is energy storage capacity in Korea?
k (IRENA,2018).06Grid Energy StorageIn KoreaSince 2018,the total capacity of all energy storage systems (ESS) connected to the Korean power sy tem has reached 1.6 GWand 4.8 GWh (NARS,2021). In terms of power capacity,40% of ESS are used for peak load reduction,36% in hybrid systems (i.e.,a combination of
Can South Korea achieve net-zero emissions?
Right now, no power plants in South Korea are fitted with carbon capture technology. The journey to net-zero emissions hinges on $2.7 trillion of investment and spending between now and 2050 to decarbonize South Korea’s energy system, 37% higher than in an economics-led transition.
How much energy storage does Korea need by 2035?
In the 10th Basic Plan, 3.7 GW (2.3 GWh) and 22.6 GW (125 GWh) of short- and long-duration storage are required by 2035, respectively. 24 According to this study, Korea needs 40 GW (182 GWh) of energy storage by 2035.
Why should South Korea deploy long-duration storage?
Deploying long-duration storage will allow Korea to capture surplus renewable energy during these off-peak periods and shift it to peak demand hours, reducing curtailment and maximizing asset utilization. This tender fits within South Korea’s broader decarbonization roadmap.
