How Do You Save Clean Energy? This Company Plans To Pump It Underground

The title of this post is the same as that of this article on Grist.

This sentence, introduces a company called Quidnet Energy.

Last week, Quidnet, a Houston, Texas-based company, announced that it lined up a contract with the New York State Energy and Research Development Authority to construct a pilot project for its “Geomechanical Pumped Storage” technology.

Reading the article, the following points can be made.

  • Quidnet is a new take on pumped storage.
  • Instead of using expensive land to store water, the water is pumped underground from a supply pond into a well.
  • It uses pumped storage supply chains and expertise.
  • Quidnet is backed by a Bill Gates energy fund.
  • About sixty percent of US power markets have the right type of rock.

The article finishes by comparing these systems with lithium-ion batteries, which double in cost every time you want to double the capacity.

Cut technology like from Form Energy, Highview Power and Quidnet might be a lot simpler.

This is very much an a must-read article.
