The molten salt thermal energy storage (MSTES) market varies by system and application development, focusing on the utilisation of molten salts for thermal energy storage. In practice, that thermal energy may come from sources of concentrated solar power (CSP). These usually consist of a mixture of sodium nitrate and potassium nitrate and are characterised by their excellent heat transfer properties and maintenance of high temperatures over long periods, rendering them ideal for thermal energy storage. The MSTES systems are designed to heat the molten salt to a high temperature with solar energy or any other heat source. The hot molten salt, stored in insulated tanks, acts as a thermal energy storage medium. Hot molten salt can be used to generate steam to run turbines to produce electricity when required. Therefore, this technology makes it possible for CSP plants to produce electricity even without sunlight, thus delivering dispatchable renewable energy.

Molten Salt Thermal Energy Storage Market Trends

The molten salt thermal energy storage (TES) market is growing with demand for renewable energy solutions and efficient energy storage techniques. Molten salt technology is useful for storing thermal energy obtained from solar and other renewable sources for later consumption, making mitigation possible for the topsy-turvy behaviour of these sources. Particularly since the energy sector has to deliver less CO2 and provide a stable grid using renewables such as wind and solar energy. Modern current trends endorse the use of molten salt storage in recovering and consuming low-grade waste heat from industrial processes that are conducive to decarbonisation practices. Advances still concern the reliability and flexibility of energy systems and the integration of molten salt TES with concentrating solar power (CSP) plants. There is also an increasing interest in energy storage solutions to facilitate the integration of intermittent renewable energy sources into the grid, especially in North America.

Challenges In Molten Salt Thermal Energy Storage Market

MSTES has been considered very promising; however, it has faced several challenges. One major challenge of MSTES is that it has a high initial cost for construction. Because they require specially designed materials and construction methods for operation at elevated temperatures, as well as for the corrosive nature of molten salts, the initial capital investments would be quite sizeable. This upfront cost may not make MSTES a very competitive form of energy storage, especially short-term, compared to other technologies. Another challenge is the increased operational complexity, along with the maintenance requirements of the MSTES system. Molten salts tend to be corrosive and, therefore, are required to have proper handling and safe operation against leakages. Besides, high temperatures should be maintained for efficient energy storage, demanding sophisticated control systems and insulation. These will generally account for high operational costs and need special expertise, thus comprising a challenge in the mainstream use of MSTES technology.

Risks & Prospects in Molten Salt Thermal Energy Storage Market

The molten salt thermal energy storage (MSTES) market is preparing for tremendous growth owing to the global trend towards renewable energy and the demand for reliable energy storage systems. One major opportunity it offers is regarding the increasing acceptance of concentrated solar power (CSP) plants. This technology is quite compatible with CSP, providing it the capability of power generation at any hour, even after sunset. Another excellent opportunity is that MSTES can be used in conjunction with other renewable power sources, which would include everything from wind and solar photovoltaic (PV) to storage during peak demand. By accumulating the excessive energy produced during peak generation, MSTES could mitigate the renewables' intermittency and offer a more consistent energy supply. It is significant in terms of broader renewables integration into the grid and eventually achieving a cleaner, more sustainable energy future.

Key Target Audience

The main target audience focused on by the Molten Salt Thermal Energy Storage (MSTES) market will be concentrated on solar power (CSP) plant developers and operators. These companies are the direct customers for MSTES systems, which made them reliable and cost-efficient energy storage systems to render their CSP plants dispatchable like the other conventional power generation sources.,, Apart from the CSP plant developers, target audiences comprise EPC contractors working either in engineering or procurement or in construction for renewable development-type projects. In that way, they embed into the model, design, build, and commission the CSP plant, including integration parts that would have to belong to MSTES systems. Also among the broader target audience are research institutions, government agencies, and investors that seek to make a mark in advancing renewable energy technologies, as their funding, policies, and research endeavours could influence how MSTES will be developed and adopted in the future.

Merger and acquisition

The molten salt thermal energy storage market has witnessed several strategic acquisitions aimed at reinforcing competences and enlarging expertise. One such acquisition was that of Mercury Energy S.L., specialising in molten salt solutions for thermal energy storage, by the Norway-based thermal energy company Kyoto Group AS in March 2022. The acquisition allowed Kyoto to build on the expertise of Mercury Energy in molten salt thermal energy storage and steam generation. A further strengthening of the molten salt thermal energy storage capabilities followed in July of 2024 by another acquisition by Kyoto Group AS. Such strategic moves allow these companies to further enhance their service offerings and expand their presence in the market. >
