Installation of Anti-freeze Systems Holds Potential to Prevent Solidifying of Molten Salts

Molten salts are most widely used material for high temperature applications such as in concentrating solar power (CSP) plants to store thermal energy for electricity generation. Although these salts have high volumetric heat capacity, these salts are associated with a relatively high melting point, which results in them solidifying in pipes in the absence of a heat source. Hence, participants in the market are increasing awareness about the installation of anti-freeze systems.

Little effort has been put into increasing the stability limit of the upper temperature of nitrates. In addition, results obtained using other cations different from alkali metals lead to a decrease in thermal stability. In order to overcome this problem, researchers are proposing confinement of the molten salt in a controlled atmosphere that allows for an increase of the partial pressure of oxygen.

Long-term Storage Systems Using Molten Salts Help Reduce Power Plant Investment Cost

Long-term storage of renewable energy and decarbonized power generation trends are contributing to the growth of the molten salt thermal energy storage market. Molten salts help to store the thermal energy produced for use at night or during periods with less sunlight. Long-term storage systems using molten salts are suitable for conventional power plant retrofits i.e. by adding electric heaters or heat pumps, storage tanks, and salt heat exchangers for steam generation to coal fired power plants. Such setups allow existing power plant infrastructure such as turbines to be kept in use, which helps to reduce the investment cost of the entire system.

Molten Salt Thermal Energy Storage Market: Overview

• Variable renewable energy is facing high demand as an energy generation method in present times. Depleting nonrenewable energy sources coupled with massive amounts of pollution and emissions created due to them have been instrumental in driving the demand for renewable – specifically, variable renewable – energy sources such as molten salt thermal energy storage.
• Increase in demand for VRE is further supported by government investments and high priority research and development projects, especially for molten salt thermal energy storage
• Molten salt thermal energy storage puts forth a unique value addition to the power sector. It can act as a means to amplify or supplement the existing energy transmission and distribution systems. This is a sought after factor in many regions as there is a high demand for improving power transmission and distribution infrastructure. This is applicable especially to developing economies, where the rapid rate of industrialization needs to be sustained by an equally fast developing power transmission and distribution network.

Push for Renewables Results in High Growth Rate of Molten Salt Thermal Energy Storage in Europe

• In 2020, Europe held 78.2% share of the overall value for molten salt thermal energy storage units. This was due to the early initiation of the molten salt thermal energy storage market in the region, caused by the stringent government regulations pertaining to emission standards and use of renewables. North America also held a substantial share at the time and the other regions barely had a stake in the molten salt thermal energy storage market.
• Most countries in Europe consider molten salt thermal energy storage as an effective method of augmenting power supply and distribution. The high importance given to the technology by the region has given it the upper hand in terms of latest developments and key player presence. The immediate future of molten salt thermal energy storage in Europe is expected to be in large capacity energy storage locations for latent heat and thermonuclear energy.
• The scenario is rapidly changing. Asia Pacific and Middle East & Africa are likely to play key role in molten salt thermal energy storage usage and technology development over the next few years. Demand for molten salt thermal energy storage is expected to account for a share of 39% in market volume in Middle East & Africa by the end of 2031.

Scope for Molten Salt Thermal Energy Storage to Remain Moderate to High in North America

• The scope of using thermal energy storage technologies in North America is relatively medium due to a matured market and loose frameworks surrounding the use of thermal energy storage
• Demand for molten salt thermal energy storage is expected to increase in the near future owing to large scale projects for planned concentrated solar power plants across the U.S. Additionally, concentrated solar plants pose a greater competitive system when it comes to net grid system costs, adding to the region favoring solar power and molten salt thermal energy storage.
