To explore the research hotspots and development trends in the LUES field, this paper analyzes the development of LUES research by examining literature related to five
The concept of seasonal thermal energy storage (STES), which uses the excess heat collected in summer to make up for the lack of heating in winter, is also known as long-term thermal storage . Seasonal thermal energy storage was proposed in the United States in the 1960s, and research projects were carried out in the 1970s.
The long term and large-scale energy storage operations require quick response time and round-trip efficiency, which is not feasible with conventional battery systems. To
This Comment explores the potential of using existing large-scale hydropower systems for long-duration and seasonal energy storage, highlighting technological challenges
With the widespread adoption of renewable energy sources such as wind and solar power, the discourse around energy storage is primarily focused on three main aspects: battery storage technology

Emphasising the pivotal role of large-scale energy storage technologies, the study provides a comprehensive overview, comparison, and evaluation of emerging energy
Governments and private energy institutions globally have been working on energy storage technologies for a long time [10, 11]. The U.S. has positioned large-scale energy storage technology as an important supporting technology to revitalize the economy, realize the New Deal for energy, and ensure national energy and resource security.
Recent advancements in electrochemical energy storage technology, notably lithium-ion batteries, have seen progress in key technical areas, such as research and development, large-scale integration, safety measures, functional realisation, and engineering verification and large-scale application function verification has been achieved.
It enhances our understanding, from a macro perspective, of the development and evolution patterns of different specific energy storage technologies, predicts potential technological breakthroughs and innovations in the future, and provides more comprehensive and detailed basis for stakeholders in their technological innovation strategies.
Energy storage is not a new technology. The earliest gravity-based pumped storage system was developed in Switzerland in 1907 and has since been widely applied globally. However, from an industry perspective, energy storage is still in its early stages of development.
There are still many challenges in the application of energy storage technology, which have been mentioned above. In this part, the challenges are classified into four main points. First, battery energy storage system as a complete electrical equipment product is not mature and not standardised yet.
Additionally, with the large-scale development of electrochemical energy storage, all economies should prioritize the development of technologies such as recycling of end-of-life batteries, similar to Europe. Improper handling of almost all types of batteries can pose threats to the environment and public health .
