Structural Protection of flywheel energy storage system

飞轮能量存储系统在旋转质量中存储大量能量。与大容量电池等其他储能系统相比，飞轮储能系统具有功率密度高、寿命长、效率高、无碳等特点。飞轮储能系统通常建造在地下，这是由于潜在的转子爆裂的安全问题。本项目针对地上建筑开发了一种高性能的围护系统。限制系统包括低碳橡胶混凝土、能量吸收泡沫铝和韧性钢覆层，将允许高抗冲击性、场外预制和易于现场安装。

A flywheel energy storage system stores a large amount of energy in a rotating mass. Compared with other energy storage systems such as large-capacity batteries, the flywheel energy storage system features high power density, long lifespan, high efficiency and is carbon-free. Flywheel energy storage systems are typically constructed underground due to safety concerns from a potential rotor burst. In the present project, a high-performance confinement system is developed aiming at above-ground construction. The confinement systems which comprise low-carbon, rubberized concrete, energy-absorbing aluminum foam, and ductile steel cladding will allow for high-impact resistance, off-site prefabrication, and easy on-site installation.
