Duck Energy is building Gravity batteries to create grid scale long term energy storage. Duck Energy utilises existing mine shafts to store energy from renewable sources and then provide the energy back to the grid at high demand times in the evening or winter. This will reduce seasonal changes in energy prices for commercial and private customers.

0 Loss Long Term Storage

Gravity batteries store energy as gravitational potential when charged this means that there is no loss due to chemical decay

0 Wait Time

Instance start time means that the service can react to grid demand is seconds

∞ Cycles

Gravity batteries can be charged and discharged without losing capacity as long as needed.

Multi-decade Life Span

With minimal upkeep and maintenance gravity batteries can have a life span of decades or longer
