Abstract
In order to decrease the dependence on fossil fuels it is of paramount importance that renewable sources are used as effectively as possible. Therefore it is necessary to store excess energy when supply is higher than de-mand. One way to do so is by storing the energy as compressed air in a porous aquifer. The Lund Sandstone in the Kyrkheddinge area, Skåne, southern Sweden, has previously been investigated for natural gas storage. This paper tries to find a method to digitalize the analog data from these investigations to create a 3D model that can be used for further studies. The model, as well as data from the previous investigations, are used to evaluate the possibilities to utilize the Lund Sandstone for compressed air energy storage... (More)
In order to decrease the dependence on fossil fuels it is of paramount importance that renewable sources are used as effectively as possible. Therefore it is necessary to store excess energy when supply is higher than de-mand. One way to do so is by storing the energy as compressed air in a porous aquifer. The Lund Sandstone in the Kyrkheddinge area, Skåne, southern Sweden, has previously been investigated for natural gas storage. This paper tries to find a method to digitalize the analog data from these investigations to create a 3D model that can be used for further studies. The model, as well as data from the previous investigations, are used to evaluate the possibilities to utilize the Lund Sandstone for compressed air energy storage (CAES) in the Kyrkheddinge area. The well logs from these investigations and from the geothermal project outside of Lund were also evaluated to compare the geo-thermal energy possibilities to the Lund Geothermal Field. This was done by calculating the net sand for the wells in the two areas. The model turned out useful for evaluating possible dome structures for energy storage and could be used to determine areas and closed volumes of the structures. The possibilities for CAES in the area are slim, but one reservoir structure beneath the so-called Brown Marker, could be worth investigating further. The measured net sand is lower in the Kyrkheddinge area than in the geothermal field, but it could still be an option for a geothermal energy plant. (Less)
