Description
Sihao Huang, Kunqing Jiang, Xin Chen, Wei Chen, and Xianbiao Bu model in 2026 a system that would store energy as compressed carbon dioxide inside basalt rock. The same system would also trap that carbon for good. Basalt reacts with carbon dioxide and locks it into minerals, yet those same reactions reshape the rock pores the storage system depends on. Their simulations tested different basalt types and operating settings.
Deployment proved workable on paper, and pumping gas in and out actually sped the dissolving of carbon dioxide into the rock water. The system could repay its build cost within its lifetime, at an electricity cost near that of porous rock air storage. Olivine rich basalt trapped carbon best, though energy performance barely differed between rock types. Injection speed drove efficiency most, while pore space governed how much carbon could dissolve.
