Abstract
A potential energy storage system incorporating multiple track mounted shuttle units having motor/generator drive bogies and structure with an integral transfer mechanism for removably carrying energy storage masses from a first lower elevation storage yard to a second higher elevation storage yard employing excess energy from the electrical grid driving the motors, removing the masses in the second storage yard for energy storage, retrieving the masses and returning the masses from the second storage yard to the first storage yard recovering electrical energy through the generators.
