A) Caverns – Big Tanks in the Salt: Development and status of cavern storage technology
In times of declining energy resources and increasing demand, people and economies are looking for stable energy supplies. For decades, salt cavern storage has contributed to Europe’s supply security. From the early beginnings up to now, storage requirements in respect of volume and availability have dramatically changed. In former times, storage facilities were only used to handle supply peaks in winter time, but now they are also trading instruments in the unbundled gas market. The influence and developments due to these new challenges for surface and subsurface installations (e.g. Leaching Facilities, Gas Drying Facilities, Compression Facilities, etc.) are highlighted in detail in the presentation.
B) Compression Systems A discussion on reciprocating compressor technology and plant solutions based on Ariel reciprocating compressors.
A flexible and stable solution for the necessary gas compressors is important. Nowadays turbo compressors and reciprocating compressors are the main types for cavern storage, but due to the development from the pure storage to a trading instrument, reciprocating compressors have experienced a “renaissance” for new storage projects!
