1. 1. Potentiella miljörisker med geoenergisystems temperaturpåverkan i mark och grundvatten

   Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Julia Nilsson; [2020]
   Nyckelord :Geoenergi; grundvattenkemi; mikroorganismer; flora; fauna; Earth and Environmental Sciences;

   Sammanfattning : The aim of this literature study was to answer whether the thermal impact of geothermal energy systems pose a potential environmental risk to groundwater quality and microorganisms in the sub surface and to above ground vegetation. This study shows that the thermal impact of high temperature systems operating with temperatures ≥25⁰C in groundwater could lead to adverse effects on groundwater chemistry and biodiversity, such as mobilization of arsenic and DOC.

3. 2. Subsurface characterization of the Lund Sandstone – 3D model of the sandstone reservoir and evaluation of the geoenergy storage potential, SW Skåne, south Sweden-merged

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Erik Aldenius; [2019]
   Nyckelord :Energy storage; CAES; geothermal energy; Lund Sandstone; renewable energy; geoenergy; Earth and Environmental Sciences;

   Sammanfattning : 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. LÄS MER

4. 3. Aquifer Thermal Energy Storage : Impact on grondwater chemistry

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Julian Kolesnik Lindgren; [2018]
   Nyckelord :ATES; Aquifer Thermal Energy Storage; groundwater chemistry; akviferlager; akviferlagring; termisk energilagring; grundvattenkemi;

   Sammanfattning : Groundwater is potentially a useful source for storing and providing thermal energy to the built environment. In a nordic context, aquifer thermal energy storage, (ATES) has not been subject to a wider extent of research concerning environmental impact. LÄS MER

7. 5. Termisk energilagring i fjärrvärmenät

   Master-uppsats, KTH/Energiteknik

   Författare :Julia Kuylenstierna; [2018]
   Nyckelord :;

   Sammanfattning : District heating is the most common form of heating in Sweden and as other industries it faces challenges in terms of increased resource utilization and transition to 100% renewable energy sources. Thermal energy storage in district heating networks can bring several advantages, for example enabling the use of excess energy, reduction of equipment size and capacity, as well as load leveling.
