The cost to capture carbon? More water and electricity

A Louisiana power company's plan to capture climate emissions is raising concerns about the state's water supplies

A carbon capture proposal for a central Louisiana power plant has been titled Project Diamond Vault" by its owner, Louisiana utility Cleco. The utility says the project will have precious value" to the company, customers and state.

Yet less than six months after announcing the project to capture carbon from the plant's emissions and store them underground near the plant, Cleco revealed in a recent filing to its state regulator the $900m carbon capture retrofit could reduce electricity produced for its customers by about 30%.
