  1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  3. 2. Increasing Photovoltaic penetration rate on isolated grid using storage, overbuilding and curtailment: Case study of the Reunion Island

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Théo Chamarande; [2019]
    Keywords : ;

    Abstract : In the global context of GHG emissions reduction, insular isolated grids which are the most vulnerable systems in terms of fossil fuel dependency have to conduct their energy transition. Conventional units using fossil fuels are well adapted to those systems because they are dispatchable, reliable and flexible, so they can easily respond to grid requirements. READ MORE

  4. 3. Utilizing Energy Storage Applied on Floating Wind Turbine Economics Using a Spot-Price Based Algorithm

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jim Johansson; [2017]
    Keywords : wind power; wind energy; energy storage; spot-price; CAES; ORES; PHES; BESS; floating wind turbine; semi-submerged; spar-type; tension-leg; intermittent wind;

    Abstract : In this paper, a new algorithm for utilizing energy storage is proposed and applied on floating wind turbine economics. The proposed algorithm’s decision making on storing energy or selling electricity onto the grid is based on the electricity price, which makes it unique and different from similar algorithms.

  5. 4. Energy Storage Technology Comparison From a Swedish perspective

    University essay from KTH/Energiteknik

    Author : FELIX SÖDERSTRÖM; [2016]
    Keywords : ;

    Abstract : Due to increased usage of renewable energy sources a need to store energy, from times of low demand or high production to times of higher demand or lower production, have risen. This report is meant to serve as a comparison between different methods of energy storage from a Swedish point of view. READ MORE

  6. 5. Energy Storage – A global overview and technological comparison

    University essay from KTH/Energiteknik

    Author : NASSIF Mansour; OSCAR LEFFLER; [2016]
    Keywords : ;

    Abstract : Energy storage systems are currently expanding worldwide. This is seen as a result of an increased amount of renewable intermittent energy in the electrical grid. Energy storage is mainly used to balance the supply and demand and increase the reliability of the grid. READ MORE
