COMBINING TOOLS TO CREATE NEW UNDERGROUND CAVERNS FOR HYDROGEN STORAGE
Hydrogen is a fast-growing energy carrier, which can be stored in large quantities in salt caverns thanks to the excellent impermeability of salt that does not react with hydrogen. Fresh water is usually pumped into these caverns to give them their final shape. This is known as salt cavern leaching and is both a lengthy and costly process.
The Hy-Wise project is intent on reducing each leaching operation by several weeks to reduce the overall cost of an alternative solution to the usually heavy-duty means needed to create such salt caverns, while improving environmental performance indicators (lower CO2 emissions). The project hopes to give FLODIM a clear competitive edge in the operation of the many salt caverns in France and Europe.
