Concrete Blocks for Energy Storage

In the medium term, the electricity grid will likely be comprised of a number of technologies for the stabilisation of supply versus demand. Part of the diversity of possible solutions are proposals such as the one in the video: a tower of concrete blocks using excess electricity to store gravitational potential energy which can be released as electricity when required. While cost projections are promising, as with almost all systems, there are challenges such as stability when there is a lot of wind, aesthetics, and round trip efficiency.

There are likely contexts where such a solution will fill the need.
