  1. 1. Modeling and analysis of a district heating system containing thermal storage

    University essay from Chalmers tekniska högskola/Institutionen för energi och miljö

    Author : Berna Melissa Akkaya; Dmytro Romanchenko; [2013]
    Keywords : district heating; optimization; modeling; thermal storage;

    Abstract : The need for space heating and hot water in the residential and services sector makes up a major part of the total Swedish energy demand. This need is to a large extent satisfied by district heating (DH). In the future, it is expected that the energy system will include a larger share of intermittent renewable energy sources.

  2. 2. Advanced Process Integration Aspects of Tubular Reactors

    University essay from Chalmers tekniska högskola/Institutionen för energi och miljö

    Author : Helena Olsson; [2013]
    Keywords : process integration; pinch analysis; tubular reactors;

    Abstract : The chemical industry had the third largest energy demand of Swedish industry in 2011. One way to lower the energy requirement is to increase the energy efficiency of a process through energy integration and therefore lower the demand of primary energy. READ MORE

  3. 3. Evaluation of buildings’ suitability as thermal energy storage in a district heating system

  5. 5. Regional development via high-speed rail : A study of the Stockholm-Mälaren region and possibilities for Melbourne-regional Victoria

    University essay from KTH/Trafik och logistik

    Author : Michael Bayley; [2012]
    Keywords : ;

    Abstract : The purpose of this thesis is to examine, based on a study of the regional high-speed corridors in the Stockholm-Mälaren Region, the possibilities for regional high-speed rail in Melbourne-regional Victoria (Australia) to improve accessibility, and achieve regional development and balanced growth between the capital and its surrounding regions. It deals with the concept of 'regional' high-speed rail, a variant of classic high-speed rail that serves centres along regional corridors stemming from a large city and whose travel purpose includes a high share of daily commuting and occasional business and leisure travel with journey times of up to two hours.
