p thermal energy storage (TES) offers advantages over lithium-ion batteries in several specific industries, particularly where high-temperature heat is required or where the focus is on process heating rather than electrical energy storage. Here are some key areas where TES is more advantageous:
Advantages of Thermal Energy Storage
- Industrial Process Heating: Industries like steel, metal processing, and chemicals rely heavily on process heat, which accounts for up to two-thirds of their total energy consumption. TES is well-suited for these high-temperature applications, storing energy at temperatures as high as 1,300°C. This capability makes TES more efficient and cost-effective for industrial heating than lithium-ion batteries, which are primarily used for electrical energy.
- Renewable Energy Integration: Thermal energy storage can capture and store waste heat from industrial processes or solar thermal systems, decoupling energy generation from immediate use. This is particularly beneficial when integrating renewable energy sources with fluctuating outputs. TES can store excess energy generated during off-peak hours for later use, thereby stabilizing the energy supply and reducing reliance on fossil fuels.
- Cost Efficiency: In terms of cost and efficiency, TES systems can be cheaper than lithium-ion batteries for high-capacity energy storage. A study from Kraftblock highlighted that thermal energy storage is more cost-effective than hydrogen-based solutions and direct electrification in some industrial processes.
- Long-Duration Energy Storage: TES systems can store energy for multiple days, offering long-duration storage capabilities that are crucial for meeting consistent industrial heat demands. This flexibility allows industries to manage energy costs better by storing low-cost electricity during off-peak times for use during peak hours.
Comparison with Lithium-Ion Batteries
- Temperature Range: Lithium-ion batteries are primarily suited for electrical energy storage and have limited thermal usability compared to TES systems.
- Energy Density and Cost: TES can be more cost-effective for large-scale applications where high temperatures are needed, making it preferable over lithium-ion batteries in these contexts.
- Application Specificity: While lithium-ion batteries are versatile across various sectors, TES is particularly advantageous in industries requiring high-temperature process heat.
In summary, thermal energy storage is more advantageous in industries where high-temperature heat is necessary, such as industrial heating, and where cost efficiency and long-duration energy storage are priority considerations.
