Deep dives
Innovative Thermal Energy Storage Solution
Fourth Power is focusing on creating a flexible and efficient thermal energy storage system that can store energy in the form of heat and convert it back to electricity when needed. This system aims to address the dual challenges of both short-duration energy storage for 5 to 10 hours and long-duration storage that can last over 100 hours, with the capability to release power rapidly. The architecture consists of circulating molten tin around carbon blocks, where heat is stored and later transformed back into electricity using thermal photovoltaics. Such a model provides a potentially lower-cost alternative to traditional lithium-ion batteries, aiming to decarbonize the grid by enhancing the capacity for renewables integration.
