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

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Simon Englund-Karlsson; [2020]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract :  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

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Anders Schweitz; [2019]
    Keywords : energy storage;

    Abstract : 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. READ MORE

  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

    University essay from Lunds universitet/Geologiska institutionen

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

    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. READ MORE

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

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Luca Santo; [2018]
    Keywords : 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;

    Abstract : 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.
