    Storing Energy in Underwater Balloons

    A RANGE OF ENERGY storage options is becoming increasingly available to respond to the growing share of renewables on the grid. But batteries alone may not address all of the potential needs for power reliability -- particularly as peak demand calls for power often at the times that renewables are least able to respond. Enter Hydrostor, a Canadian startup that has launched the world's first underwater compressed-air energy-storage solution. Hydrostor recently brought online a grid-connected, 1-MW system using inflatable balloons positioned 180 feet below the surface of Toronto's Lake Ontario. The system -- capable of holding enough energy to power 330 homes -- will be operated by Toronto Hydro. The utility intends to use the Hydrostor system to store electricity during offpeak hours and then tap into it as demand grows

    1. We founded the company five years ago looking at small-pump hydro and realized that it's tough to make those economics work.
    2. Compressed air is a pretty well-known technology.
    3. It's tough to compete on the mainland with natural gas -- especially the way the prices are right now in the U.S..
    4. If we're going to do something about climate change and move our grids to 100% renewables, then there needs to be a lot of storage added.
