What is liquid carbon dioxide energy storage (LCEs)?

In transcritical and supercritical CCES systems, the dependence on geographical conditions is one of the main obstacles limiting the application of technology. Liquid carbon dioxide energy storage (LCES) , which uses liquid storage to store CO2, is a new development direction without geographical restrictions.

Is liquid carbon dioxide energy storage a hotspot?

As a promising energy storage technology, liquid carbon dioxide energy storage has become a hotspot due to its high energy density and less restriction by the geographical conditions.
