The molten salt segment is set to exceed a value of USD 84.3 billion by 2032. CSP plants use molten salt TES systems to store thermal energy collected during daylight hours, which can then be used to generate electricity during periods of low solar irradiance or after sunset. This ability to provide dispatchable power is a significant driver of the molten salt TES market.
The power generation application is anticipated to grow at a CAGR of more than 6.2% through 2032. Some of the key parameters for increasing penetration of thermal energy storage in power generation include increased renewable energy integration, advancements in storage technology, demand for grid stability, and supportive government policies promoting efficient and reliable energy storage solutions.
Asia Pacific thermal energy storage market is projected to reach USD 42.7 billion by 2032. The deployment of concentrated solar power (CSP) plants is increasing, with molten salt TES systems being a key component. Countries with high solar irradiance, such as China and India, are leading in CSP developments. The rising energy demand in Asia-Pacific countries is driving the adoption of TES systems to enhance grid stability, manage peak loads, and improve overall energy efficiency. Rapid urbanization and industrialization contribute significantly to this increased demand.
The U.S. thermal energy storage market is poised for significant growth, driven by technological advancements, increasing renewable energy integration, and supportive government policies. While challenges remain, ongoing research, investment, and the trend towards hybrid energy storage solutions are expected to propel the market forward, making TES a critical component of the nation's energy infrastructure.
