a bank for wind power - electricity storage
Tim Tevez, sitting between the Australian mainland and Tasmania, says King's Island does not seem to be a beacon for the future.
However, in a large metal shed near the west coast of the island, there is a power storage system that is expected to change the role of wind energy.
King's Island is not connected to the continental grid and, in addition to its own small wind farm, it has long relied on diesel generators for power supply.
In 2003, a huge rechargeable battery was installed by local utilities to ensure that as little wind energy as possible was wasted, and that changed.
When the wind is large, the turbines of the wind farm generate more electricity than the Islanders need.
The battery is used to absorb the excess and pump it out again on days when the wind is weakened and the turbine output drops.
Battery installation has reduced the amount of fuel burned by diesel generators by almost half, not only saving money, but also saving at least 2000 tons of carbon dioxide emissions per year. So what’s new?
Wind turbines and solar generators have been connected to the back for years
A battery that stores energy in chemical form. In the lead-
The most commonly used is acid batteries, and the chemicals that store energy remain inside the batteries.
Unlike the installation on King's Island, when there is enough wind, energy-
Rich chemicals are drawn out of the battery and injected into the tank to allow fresh chemicals to absorb more charge.
This flow is a simple reversal in order to regenerate the current.
