Key technological breakthroughs in thermal energy storage (TES) systems
Key technological breakthroughs in thermal energy storage (TES) systems revolve around innovative materials, improved efficiency, and scalable, cost-effective designs that enhance the use of clean energy and support decarbonization efforts.
Major Technological Breakthroughs in Thermal Energy Storage
1. Electrically Conductive Firebrick for Industrial Heat Storage
Electrified Thermal Solutions developed an electrically conductive firebrick that can store heat without embedded wires, making it a cost-effective and scalable TES option for high-temperature process heat applications in hard-to-decarbonize industrial sectors like cement, iron, and glass manufacturing. This breakthrough uses clean electricity to generate and store heat, enabling industries to transition from fossil fuels to electrified thermal processes.
2. Trimodal Thermal Energy Storage Material
Researchers at Monash University discovered a novel “trimodal” TES material combining three forms of energy storage within one material, delivering unprecedented thermal energy storage efficiency. This material, made from a mixture of boric acid and succinic acid, can store an exceptionally high energy density (~600 MJ/m³) and is sustainable and inexpensive. It transitions at around 150°C, suitable for renewable energy applications that require reliable and efficient heat storage. This breakthrough represents a significant leap forward, enabling more effective and sustainable thermal storage to better harness renewable energy.
3. Phase Change Materials (PCMs)
Advances in PCMs have been pivotal, as these materials store and release large amounts of energy during phase transitions (e.g., melting and solidifying). PCMs improve energy density and enable better thermal regulation, making them highly effective for both heating and cooling applications. This technology contributes to more responsive and flexible TES systems and is a key area of innovation.
4. Integration with Renewable Energy Systems
Thermal storage systems increasingly complement solar energy installations by storing solar heat during the day and releasing it at night or during cloudy periods to generate steam and drive turbines. This integration helps balance energy supply and demand, enhances grid reliability, and maximizes the utilization of renewables.
5. Cost-effective Demand Flexibility and Energy Efficiency
R&D programs focus on developing TES technologies that reduce peak electricity demand and improve energy efficiency in buildings and industrial processes. These systems provide demand flexibility, support grid stability, and enable the use of clean energy for heating and cooling.
