Problem
Industrial facilities relying on fossil fuels for process heating and electricity generation face increasing pressure to decarbonize their operations. Intermittent renewable energy sources like solar and wind require effective storage solutions to provide a continuous, reliable supply of clean energy. Traditional thermal energy storage systems often lack the capacity and scalability needed to meet the demands of large-scale industrial applications.
Solution
MGA Thermal provides a long-duration thermal energy storage system that converts excess renewable energy into high-capacity heat, enabling a continuous and reliable supply of clean steam and power for grid and industrial applications. The core of the system utilizes Miscibility Gap Alloys (MGA) in modular blocks, offering a safe and scalable method for storing large amounts of energy as heat. These MGA blocks are stacked into insulated tanks, storing energy for hours or even days, and can be integrated with existing infrastructure to maximize utilization of pre-existing equipment. This approach facilitates the electrification of high-grade process heating, reduces energy costs, enhances energy security, and significantly lowers Scope 1 & 2 emissions for businesses and governments.
Target Audience
The primary target audience includes industrial facilities in sectors such as food and beverage, mineral processing, chemicals, and materials manufacturing, as well as grid operators seeking to integrate renewable energy sources and decarbonize their operations.
