Natural gas is compressed and stored either in permeable porous rock filled naturally with water (an Aquifer layer), 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.
This involves storing natural gas in a former reserve that is no longer used. The reserve is converted to inject natural gas into a sealed geological structure, which has already held substances for millions of years.
French anti-terrorist regulations (Vigipirate) do not allow the general public to visit "sensitive" industrial sites. However, we do have teaching tools to explain the gas supply chain to primary school children, covering the production, transport, storage, and distribution of natural gas, as well as films explaining how gas storage works, drilling, etc.
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 any risk of inflammation (ban on smoking and using spark-producing devices, etc.).
The work will mainly mean more road traffic near the site, to bring materials or remove ballast from the excavation work. Storengy will ensure that any inconvenience due to machinery and trucks is kept to a minimum. Work supervisors will regularly inform local residents about progress and any impact the work might have on local life.
Please visit our Recruitment section where you will find details of our jobs along with openings. Any applications for jobs not listed under openings will also be considered.
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 are also replacing gas-powered engines and turbines with electric motors to reduce the site’s environmental impact (by reducing the emission of combustion gases). All French storage sites are certified to ISO 14001 environmental standards.
Reservoirs dug in porous rock (sandstone) whose spongy formations naturally fill with water.
Coefficient, expressed as a percentage between zero and 100 which, for a given Day on a Storage Group, reflects the physical withdrawal constraints for conditional capacity, due to the Customer’s Inventory Level on the Day in question, as defined in the Physical Characteristics of the Storage Groups.
Set each day by multiplying the Maximum Conditional Injection Capacity by the Conditional Injection Reduction Factor for that Day
Set each day by multiplying the Maximum Conditional withdrawal Capacity by the Conditional Withdrawal Reduction Factor for that Day.

Depleted gas or oil reserves can be converted in a fairly simple way into underground storage sites. It involves injecting natural gas into a geological formation that has previously stored hydrocarbon over several million years. The wells are tailored to their new function and a power station is installed to run the facilities.
Coefficient, expressed as a percentage between zero and 100 which, for a given Day on a Storage Group, reflects the physical Injection constraints due to the Customer’s Inventory Level on the Day in question, as defined in the Physical Characteristics of the Storage Groups.
