  1. 1. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Santiago Elejalde Bolaños; [2022]
    Keywords : thermophilic anaerobic digestion; volatile fatty acids; mixed sludge; organic loading rate; alkalinity; wastewater treatment plant; termofil rötning; flyktiga fettsyror; blandslam; organisk belastning; alkalinitet; avloppsreningsverk;

    Abstract : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. READ MORE

  2. 2. Assessing Sweden's future prospect for domestic hydrogen production based on lifecycle assessment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fredrik Tannoury; [2022]
    Keywords : Technology Readiness Level; Hydrogen production; LCA; Sweden;

    Abstract : Humanity faces challenge to satisfy its growing energy demand while simultaneously transitioning into a sustainable society. Reducing carbon emissions from the industrial and transportation sector are met with difficulties. To help decarbonisation efforts EU members like Sweden have recognised the use of hydrogen as a viable solution. READ MORE

  3. 3. Process Development in Hydrogen Production

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Axel Lindwall; [2022]
    Keywords : Design Research Methodology; Requirements; Modularization; Modularisation; Process Development; Hydrogen; DRI; H2GS; H2 Green Steel; Electrolyser; Electrolyzer; Electrolysis;

    Abstract : H2 Green Steel AB was founded in 2020 to build a large-scale green steel factory in Boden, Norrbotten, Sweden. The factory consists of green hydrogen production, iron production and steel production. In 2030, the factory’s annual steel production will be 5 million tonnes annually. READ MORE

  4. 4. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

    Author : Tim Günter; [2022]
    Keywords : ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

    Abstract : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. READ MORE

  5. 5. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    University essay from Lunds universitet/Kemiska institutionen

    Author : Andras Szanthoffer; [2022]
    Keywords : Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Abstract : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. READ MORE
