Just short of two miles off the coast of Toronto, a series of six massive, cylindrical balloons rise from the ocean floor, standing almost as tall as a two-story house. Their walls contain compressed air with the potential to become electricity.
These balloons are part of an innovative, emissions-free scheme to store renewable energy from the company Hydrostor.
You see, wind energy is wonderful and solar panels are superb, and these technologies becomes more efficient every year. Yet, one of the biggest challenges for renewable energy is powering homes during off-peak times, once the winds die or after the sun sets, when communities often turn towards burning diesel.
“Storage really is the key piece to allow our electrical grid to go renewable,” says CEO of Hydrostor Curtis VanWalleghem.
