  1. 16. Toward prototyping metabolic pathways in cyanobacteria using cell extracts

    University essay from KTH/Proteinvetenskap

    Author : Amina Bensabra; [2022]
    Keywords : cyanobacteria; metabolic engineering; cell-free metabolic engineering; enzymes; sustainability; cyanobakterier; metabolisk genteknik; syntetisk biologi; enzymer; hållbar bioproduktion;

    Abstract : Cyanobakterier är intressanta mikroorganismer för produktion av biobränslen från solljus, vatten och atmosfärisk koldioxid och anses därför vara potentiella mikrobiella cellfabriker. Men på grund av långsam tillväxt och låg produktion är genteknologi processen intensiv och tidskrävande för cyanobakterier. READ MORE

  3. 17. Improved Energy Efficiency of Passenger Ships in the Stockholm Region

    University essay from KTH/Energiteknik

    Author : Josefine Ström; [2022]
    Keywords : Public transport on sea; energy efficiency; ships; energy efficiency measures; Kollektivtrafik till sjöss; energieffektivisering; fartyg; energieffektiviseringsåtgärder;

    Abstract : Liksom många andra transportslag står kollektivtrafiken till sjöss inför utmaningar när det gäller ökade bränslepriser och strängare energi- och utsläppsmål. Trafikförvaltningen, den organisation som ansvarar för kollektivtrafiken i Stockholm, har flera mål för reduktion av utsläpp och energiförbrukning, både generellt för hela kollektivtrafiken samt mer specifikt för sjötrafiken.

  4. 18. Prediction of flue gas properties using artificial intelligence : Application of supervised machine learning by utilization of Near-Infrared Spectroscopy on solid biofuels

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Bashe Abdirahman Hussein; Emran Samimi; [2022]
    Keywords : Artificial Intelligence; Machine learning; Near-Infrared spectroscopy; Solid biofuels; Fuel element; Flue gas composition; CCS;

    Abstract : This degree project studies implementation and comparison of different AI models to predict (1) solid biofuel elements including carbon, hydrogen, nitrogen, and oxygen as well as moisture content, ash content, and higher heating value (HHV) of the fuel and (2) flue gas compositions such as concentration of carbon dioxide, carbon monoxide, nitrogen, nitrogen oxides, and water content using near-infrared spectroscopy and chemometric approaches. The study executes these predictions by simulating the operation of a combined heat and power plant (CHP) that is equipped with carbon capture and storage (CCS). READ MORE

  5. 19. Potential social impacts of a possible implementation of the Pulp & Fuel concept for producing biofuels at a pulp mill

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Nora Efraimsson; Sofie Johnsson; [2022]
    Keywords : biofuels; process implementation; pulp fuel; Social Life Cycle Assessment; social impacts; sustainability; forest residues;

    Abstract : The purpose of this study is to create an understanding of what potential social impacts (both positive and negative) the concept of P&F will have and could have if an implementation of the process would be done. Interviews are mainly used for providing input to the method S-LCA (Social Life Cycle Assessment) and by that fulfil the purpose. READ MORE

  6. 20. Implementation of large-scale heat storage of excess heat in Växjö´s combined heat and power plant. : A techno-economic analysis

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Parit Chandrasardula; [2022]
    Keywords : CHP plant; Excess heat; Borehole Energy storage; Lake Source Cooling;

    Abstract : To achieve greater economic stability, CHP plant operators such as VEAB from Växjö are motivated to search for a new business model that are compatible with their existing facilities while also contribute to increasing the overall revenue of the company. These processes include hydrogen production and biochemical products such as biopolymer and biofuels. READ MORE
