    Let’s do some math:

    2.1GWh

    And

    Multi billion dollar price (let’s assume 3 billion)

    2.1GWh - > 3billion

    2.1MWh - > 3 millon

    2.1kWh - > 3000 Usd /2.1

    1KWh - > ~1430 USD

    Considering that 1kWh in lithium ion batteries is like 150 USD they aren’t getting a good value out of it.

      I don’t think the multibillion price tag is about the physical battery itself.

      It’s probably the cost of the entire project. Which includes:

      • Project management
      • Engineering
      • Digging the whole
      • Security
      • Maintainance
      • Environmental impact analysis (among many other analysis)
      • Reducing the environmental impact
      • Permits (and a LOT of bureaucracy)

      The list goes on. Notice how I didn’t even mention the battery itself.

      Larger startup cost, but over the one power plant’s lifetime the Li batteries would wear out and have to be replaced many times.
