1. 1. Greenhouse gas emissions and energy efficiency of various renewable energy pathways in the truck industry : An LCA and energy efficiency analysis on fuel production for and manufacturing of 40 tonne heavy trucks in Sweden

   Master-uppsats, Linköpings universitet/Institutionen för tema; Linköpings universitet/Filosofiska fakulteten

   Författare :Jacob Axell; [2023]
   Nyckelord :Hydrogen; Sweden; 40-tonne haulage truck; LCA; Wind energy; Bio fuel; Energy efficiency; CO2 emissions;

   Sammanfattning : This study focuses on assessing the greenhouse gas emissions and energy efficiency of 40-tonne haulage trucks in fuel production and manufacturing in a Swedish context. The aim was to provide accurate greenhouse gas accounting and evaluate the contribution to mitigating climate change. LÄS MER

3. 2. Production and analysis of novel disulfide variants of Subtilisin Carlsberg

   Master-uppsats, Linköpings universitet/Kemi

   Författare :Anton Elfstrand; [2023]
   Nyckelord :Subtilisin Carlsberg; Disulfide; Protein Engineering; Kinetic Stability;

   Sammanfattning : Protein engineering has been used to alter the stability of proteins for several decades withmuch success, one approach being to introduce two cysteine residues that together form adisulfide bridge. The disulfide bridge can increase the Gibbs free energy of the transitionstate, thus increasing energy difference between the folded state and the unfolding transitionstate, leading to increased kinetic stability of the protein.

4. 3. Techno-economic and environmental analysis of alternative pathways for urea fertilizer production.

   Master-uppsats, Linköpings universitet/Industriell miljöteknik

   Författare :Wilson Rodriguez; [2023]
   Nyckelord :Urea fertilizer; ammonia; natural gas; biogas; GWP; PE; hydrogen; nitrogen; technologies.;

   Sammanfattning : The increasing global population has placed significant pressure on meeting food demands, leading to the widespread use of fertilizers to enhance crop yields. Urea, being the most used fertilizer globally, has contributed to improved agricultural productivity. LÄS MER

5. 4. Policy Incoherence in the Development of Biogas in the Road Transport Sector

   Master-uppsats, Linköpings universitet/Institutionen för tema

   Författare :Natali Fanari; [2023]
   Nyckelord :Biogas; transport; policy incoherence; policy instruments; biogas development;

   Sammanfattning : Sweden has one of the highest biogas potentials in the world and has been a leader in reducing fossil fuels in the transportation industry. With a goal of achieving a 70% reduction of greenhouse gas emissions in domestic transport by 2030 compared to 2010 levels and net-zero greenhouse gas emissions by 2050, despite the potential advantages of biogas implementation, its adoption in the Swedish transport sector has been limited.

7. 5. The Optimal Bidding Strategy of a Wind-Biogas-Hydrogen Hybrid System

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Xudong Liu; [2022]
   Nyckelord :bidding strategy; wind; biogas; hydrogen; hybrid system; two-price settlement;

   Sammanfattning : The growing penetration of variable renewable energy has brought all-round challenges to the current power system, no matter for the grid infrastructure, market design or the power producers. The positive and negative externalities caused by the market participators are to be finer priced and a significant amount of flexibility is to be added to the system, in order to counter these problems and facilitate energy transition.
