Abstract

Thermal energy storage (TES) has emerged as a critical technology for enhancing the flexibility of energy systems and the integration capacity of renewable energy sources by addressing mismatches in the temporal

spatial

and intensity dimensions of energy supply and demand. This study conducted a comprehensive review and analysis of nearly 30000 scholarly publications using systematic review and scientometric knowledge mapping methodologies to delineate the research progress

application landscape

and development trends in the TES field. The investigation reveals that research activity in TES has experienced sustained and rapid growth

evolving into a multi-layered knowledge architecture structured around "Materials-Systems-Applications." A distinct global research landscape has materialized

characterized by a tripartite leadership comprising China

the United States

and Europe

each exhibiting unique strategic focuses and developmental trajectories. The current research frontier is primarily concentrated on the pursuit of high performance

system intelligence

and deep integration. Key areas of intense focus include: (1) long-duration energy storage technologies

notably thermochemical heat storage and calcium looping (CaL) cycles; (2) intelligent responsive materials

such as MXene-based composite materials and those whose properties can be modulated by magnetic fields; (3) multi-energy coupled integration

with core applications in integrated energy systems (IES) and Carnot batteries; and (4) machine learning (ML)-enabled optimization across the entire TES chain

from material discovery to system design and operational control. To propel the large-scale application of TES technologies

concerted innovation across material

system

and market dimensions is urgently required. Future efforts must prioritize overcoming key technical bottlenecks

such as enhancing material cyclability and energy density for long-term storage

improving the efficiency and intelligence of system integration

and developing robust market mechanisms and policy frameworks. This study provides a systematic

data-driven overview that can serve as a foundational reference for researchers

policymakers

and industry stakeholders navigating the evolving landscape of thermal energy storage.
