How is natural gas stored below the ground?

Natural gas is compressed and stored either in permeable porous rock filled naturally with water (an aquifer layer), in hydrocarbons (depleted fields), or in caves dug in layers of salt (salt caverns). These underground reserves are filled up in the summer to meet high consumption during the winter months.

I live near a storage site. Is there a risk of explosion?

When natural gas is stored under the ground, it cannot catch fire as there is no oxygen. However, in surface facilities, very strict safety rules are applied to eliminate risk of fire and explosion (eg ban smoking etc…)

Does a natural-gas storage site pollute?

Natural gas is not toxic. Operating a storage site requires the use of chemical products that are used carefully to avoid affecting the atmosphere or polluting the ground. Runoff water is collected on the site and treated. Waste is also sorted and eliminated in line with the regulations.

We will also be using electric motors to reduce the site’s environmental impact (by reducing the emission of combustion gases).
