    Sammanfattning : Recent literature shows that there is a significant potential of decarbonisation and efficiency improvement that can be achieved through the synergy from multi-energy systems (MESs). Coupling technologies, such as co-generation plants, heat pumps and thermal storages are widely recommended as means of unlocking additional flexibility and increasing the penetration of renewables in the heating and electricity sectors.

  4. 3. Modelling District Heating Network Costs

    Författare :Luis Sánchez-García; Urban Persson; Helge Averfalk; Erik Möllerström; Marcus Thern; Magnus Åberg; Sweden Lund Lund University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District Heating; Pipe network; Cost analysis; Distribution Capital Cost; Effective Width; Plot Ratio; Heat Density; GIS; Smart Cities and Communities; Smarta städer och samhällen;

    Sammanfattning : The solution of the undergoing climate and energy crises requires a radical transformation of the energy system, in which sustainability, no carbon emissions and energy efficiency ought to play a paramount role. This revolution should extend to all areas of the energy system, including the space heating and cooling sector, which accounts for a third of the European final energy demand and, in the European continent, it is still mostly supplied by fossil fuels.

  5. 4. To analyse measurements is to know!

    Författare :Henrik Gadd; Institutionen för energivetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Hourly meter readings; fault detection; Low return temperature; temperature difference.;

    Sammanfattning : Renewable energy sources dominated the world energy supply until the beginning of the 20th century, when fossil energy became the dominant energy source worldwide. Today, fossil fuels contribute to over 80% of world energy supply. But there are two major reasons why fossil energy use has to stop. LÄS MER

  7. 5. Distributed wireless control strategies for district heating substations

    Författare :Jonas Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : The overall fuel efficiency of district heating could clearly be improved by using new strategies for measurement and control. The potential for improvement is on the order of several percent. LÄS MER
