Abstract
For at nå målet om uafhængighed af fossile brændsler i 2050 har indsatsen især fokuseret på el-, varme- og transportsektoren, mens køling har fået mindre opmærksomhed. Dette speciale undersøger, hvilke energibesparelser og CO2-reduktioner Danmark kan opnå ved at udnytte potentialet for fjernkøling—et system hvor afkølet vand produceres centralt og distribueres gennem rør for at køle bygninger. Problemformuleringen er: Hvor store besparelser i bruttoenergiforbrug (det samlede energiforbrug) og CO2-udledning kan fjernkøling give, og hvilke barrierer hæmmer implementeringen? Metodisk bygger undersøgelsen på en teoretisk forståelsesramme. Derudover anvendes EnergyPLAN til at vurdere konsekvenserne for energisystemet, mens kvalitative metoder, herunder interviews og litteraturstudier, bruges til at identificere barrierer for udbredelsen. Resultaterne viser, at udnyttelse af fjernkølingspotentialet kan reducere energiforbruget med ca. 1,3 TWh og CO2-udledningen med omkring 445.000 tons. Samtidig peger analysen på flere barrierer, som tilsammen gør fjernkølingsmarkedet mindre attraktivt. Der er ikke én enkelt afgørende barriere; kombinationen vurderes at begrænse udbredelsen af fjernkøling i Danmark.
To meet the goal of becoming independent of fossil fuels by 2050, efforts in Denmark have mainly focused on the electricity, heating, and transport sectors, while cooling has received less attention. This thesis examines the energy savings and CO2 reductions Denmark could achieve by using the potential for district cooling—systems where chilled water is produced centrally and distributed through pipes to cool buildings. The research question is: How large are the potential reductions in overall energy use (gross energy consumption) and CO2 emissions from district cooling, and what barriers hinder its implementation? The study is grounded in a theoretical framework. It uses EnergyPLAN to assess impacts on the energy system and applies qualitative methods, including interviews and literature reviews, to identify barriers to wider uptake. The results indicate that fully utilizing district cooling could reduce energy use by about 1.3 TWh and cut CO2 emissions by approximately 445,000 tons. However, multiple barriers together reduce the attractiveness of the district cooling market. No single barrier is decisive; rather, their combination is expected to limit the expansion of district cooling in Denmark.
