Europe's total natural gas storage capacity is about 110 billion cubic meters, with Germany, Italy, France, the Netherlands, and Austria holding two thirds of this capacity.

Most natural gas storage in Europe is concentrated in just a few countries. Germany, Italy, France, the Netherlands, and Austria dominate storage capacity, collectively controlling about two thirds of the total 110 billion cubic meters capacity. This concentration means that the energy security of the continent depends heavily on how well these countries fill and manage their gas storage.
