The Push to Store Renewable Energy in Massive Salt Caverns

Phred Dvorak of The Wall Street Journal reports on how salt caverns could store renewable energy.

The C3 Take
  • America’s underground salt caverns are being tapped as a potential solution for renewable energy storage.
  • The process works like this: renewable energy sources are used to create hydrogen which is then stored underground in salt caverns by a process called leaching.
  • The hydrogen is then tapped when needed for several processes such as transportation fuel and industrial decarbonization.

“Green Hydrogen International, a company planning a cavern project in South Texas, estimates it would take around 38,500 Tesla Megapacks—a type of battery popular for large-scale utility installations—at an estimated cost of $59 billion to store the amount of energy it is hoping to keep in its caverns, which it estimates will cost $150 million to make.”
