  1. 1. Energy storage and their combination with wind power compared to new nuclear power in Sweden : A review and cost analysis

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Simon Englund-Karlsson; [2020]
    Nyckelord :Energy storage; wind power; nuclear power; levelized cost of energy; levelized cost of storage; review; cost analysis; LCOE; LCOS; pumped hydro storage; compressed air energy storage; battery storage; PHS; CAES;

    Sammanfattning : As intermittent renewable energy sources such as wind and solar power gradually increase around the world, older technologies such as nuclear power is phased out in Sweden and many other countries. It is then important to ensure that the total power need is secured, and that the power grid can remain stable. LÄS MER

  3. 2. A 3D Sub-Surface Characterisation of the Arnager Greensand, South-west Skåne

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Gregory Marcel Davies Jones; [2019]
    Nyckelord :Arnager Greensand; digitization; depth conversion; reservoir; storage potential;

    Sammanfattning :  A surface characterisation of the Arnager Greensand in south Sweden, a deep saline aquifer found to be suitable for geological storage of CO2 or energy storage, was undertaken in this thesis. Vintage seismic reflection data only available as scanned tiff images of the final stacked sections were digitized and processed using modern interpretation software to provide new insights into the morphology of the Arnager Greensand and to analyse the reservoir’s potential as an energy storage unit.

  4. 3. The potential of grid energy storage: a case study of the Nordic countries and Germany

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Anders Schweitz; [2019]
    Nyckelord :energy storage;

    Sammanfattning : The increasing share of renewable electricity will make energy storage technologies indispensable in the future. In this study, the potential of grid energy storage technologies is discussed, focusing on the Nordic countries as well as Germany. LÄS MER

  5. 4. 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

  7. 5. AA-CAES physical modelling: integration of a 1D TES code and plant performance analysis

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Luca Santo; [2018]
    Nyckelord :energy storage; balancing; grid; AA-CAES; CAES; peaks; energy scenarios; s-function; simulink; simscape; matlab; C ; TES; thermal energy storage; dumping; demand side management; power systems; turbine; compressor; cavern; CAS; compressed air; heat exchange;

    Sammanfattning : The focus of this thesis work was the development of an approachto couple a previosly existing Thermal Energy Storage (TES) modelwritten in C++ with a Simulink/Simscape plant model to simulate anAdvanced Adiabatic Compressed Air Energy Storage (AA-CAES) plant.After the creation and validation of such tool, the complete modelwas used to run simulations, with the aim of assessing the AA-CAESplant's performance under multiple patterns of charge anddischarge.
