Empelde gas caverns
The Empelde gas caverns near Empelde are underground natural gas storage facilities below the area of the town of Ronnenberg . The caverns and technical facilities for the storing of natural gas have for decades been part of the energy industry infrastructure in northern Germany and integrated into the transmission system of Nowega (Munster) and enercity (Hannover). The Empelde gas caverns is operated by GHG - Gasspeicher Hannover GmbH (GHG), which is a joint venture between Stadtwerke Hannover and Erdgas Münster .
history
The Benther salt dome extends underground between the Hanoverian district of Badenstedt and the Ronnenberg district of Weetzen . Until the 1970s, two used potash - salt mines the mineral resources. Of these, the Hansa potash plant in Empelde was shut down in 1973 for economic reasons.
After groundwater had seeped into the mine building of the Ronnenberg potash plant with its shaft in Ronnenberg and tunnels as far as Benthe and Weetzen and had left large, unsecured cavities after the drain, subsidence in the area occurred on July 26, 1975 : road pavements tore open , Craters formed and residential buildings sagged to the point of uninhabitable. In order to end the danger of sinkholes , two relief bores were then made in the area around Ronnenberg, through which the mine was quickly flooded with water from the Feldmark - and at the same time the salt mine was "[...] abandoned forever".
In 1977 the GHG company was founded to implement the plans for the construction of natural gas caverns in still unused areas of the salt dome west of Empelde. In 1983 the plant could then be put into operation by GHG. The modernization and expansion of the facilities began in 2003. Four caverns were in use at the end of 2015, and another underground storage facility is under construction and more are being planned.
In the meantime, the citizens' initiative bürgerforum-gaskavernen.de was formed in 2009 due to the “humming noises” that were disturbing to the residents .
