  1. 1. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

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

    Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
    Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Abstract : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

  3. 2. Seawater Heat Recovery by the Utilisation of Phase Change Heat of Freezing : Technical feasibility study of a system for District Heating in the city of Helsinki

    University essay from KTH/Kraft- och värmeteknologi

    Author : Rakesh Ramesh; [2022]
    Keywords : District heating; Seawater; Ice slurry; Aspen Plus; Pressure drop; Fjärrvärme; Havsvatten; Isslurry; Aspen Plus; Tryckfall;

    Abstract : With the Paris agreement calling to limit global warming to 2°C below pre-industrial levels, with further efforts to ensure it stays below 1.5°C, the Finnish government passed the Lakihiilen energiakäytön kieltämisestä (416/2019), i.e. READ MORE

  4. 3. Climate change mitigation from biochar production at farm level : A time dynamic LCA study of wheat

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Louise Jungefeldt; [2022]
    Keywords : Pyrolysis; agricultural by-products; life cycle assessment; waste valorization; carbon sequestration;

    Abstract : Agricultural production in Sweden account for a large contribution of the territorial GHG emissions. System optimization, fossil fuel removal and increased circularity is therefore of great importance in order to reach the national net zero emission target by 2045. READ MORE

  5. 4. Side Streams Throughout the Food Supply Chain in Västra Götaland - A Study of Reported Data, Interviews with Food Producers and a Simplified LCA Case Study

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Emma Kihlberg; [2020]
    Keywords : Food waste; Food loss; Side streams; Food supply chain; Västra Götaland; Food producers; LCA; Life cycle assessment; Sidoströmmar; Livsmedelskedjan; Livsmedelsproduktion; Livscykelanalys; Matsvinn; Matavfall; Technology and Engineering;

    Abstract : Vikten av resurseffektivitet i livsmedelskedjan är tydlig, eftersom denna sektor är en av de största bidragarna till negativ klimatpåverkan globalt. Målet med den här uppsatsen var att utforska sidoströmmar av mat inom livsmedelskedjan i Västra Götaland, för att kartlägga hur mycket som redan är täckt i statistiken och vilka luckor i datamaterialet som finns för framtida forskning att täcka.

  6. 5. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Henrik Johansson; [2018]
    Keywords : Raman; Raman Spectroscopy; Raman scattering; biomass; biofuel; thermal conversion; pyrolysis; gasification; laser diagnostics; laser-induced fluorescence; LIF; energy; wood pellets; ammonia; aldehydes; ketones; formaldehyde; acetaldehyde; acetone; combustion physics; Physics and Astronomy;

    Abstract : This thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. READ MORE
