1. 6. Compressed air energy storage : Process review and case study of small scale compressed air energy storage aimed at residential buildings

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Evelina Steen; Malin Torestam; [2018]
   Keywords : compressed air energy storage CAES ; electrical energy storage EES ; artificial air storage; thermodynamic analysis; economic evaluation; tryckluftsenergilagring CAES ; elektrisk energilagring EES ; artificiell luftförvaring; termodynamisk analys; ekonomisk utvärdering;

   Abstract : The potential for electrical energy storage to both provide services to the electrical grid and help to better integrate renewable energies in the electrical system is promising. This report investigates one type of storage, compressed air energy storage (CAES), where energy is stored by compressing air during hours of low electricity demand and later expanding the air to generate electricity during high demand hours.

3. 7. On the Feasibility of Thermochemical Energy Storage for CSP plants : Technology Evaluation and Conceptual Design

   University essay from KTH/Kraft- och värmeteknologi

   Author : Katerine Antil Martini; [2018]
   Keywords : ;

   Abstract : This master thesis focuses on the review of the thermochemical energy storage (TCES) concept and its application in Concentrated Solar Power (CSP) plants. The TCES concept has been reviewed and critically analyzed, highlighting the advantages and digging into the challenges that this technology must overcome to reach commercial scale. READ MORE

4. 8. Steam driven boiler feed pumps for Lakvijaya Power Station, Sri Lanka

   University essay from Högskolan i Gävle/Energisystem

   Author : Buddhika Hasantha Wanasinghe; [2017]
   Keywords : steam driven; electric motor driven; BFP; coal; SRI LANKA; sub-critical;

   Abstract : Energy saving in coal power plants is a popular topic in present days with the global energy crisis. Internal electricity demand or auxiliary power consumption is an energy portion related with equipment supportive to the main equipment, which is unavoidable but with a proper investigation, some amount of this energy can be saved either by introducing thermally efficient auxiliary equipment or improving efficiencies of available equipment.
