  1. 1. Heat recovery from low emission steel production through electrolysis and hydrogen reduction

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Sofia Kongshöj; [2023]
    Keywords : Electrolysis; H2 Green Steel H2GS ; waste heat recovery; district heating.; Earth and Environmental Sciences;

    Abstract : The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. READ MORE

    University essay from KTH/Materialvetenskap

    Author : Roberto Vita; [2022]
    Keywords : Industy 4.0; Machine Learning; Statistical Modeling; Temperature Prediction; Vacuum Tank Degasser; Vacuum Treatment Step.; Industri 4.0; Maskininlärning; Statistisk modellering; Temperaturförutsägelse; Vakuumbehandlingssteg; Vakuumtankavgasare;

    Abstract : In recent years the steelmaking industry has been subjected to continuous attempts to improve its production route. The main goals has been to increase the competitiveness and to reduce the environmental impact. The development of predictive models has therefore been of crucial importance in order to achieve such optimization. READ MORE

  4. 3. Deriving and mitigating the upfront carbon of a large-scale industrial project

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hugo Jennehov; Nils Olofsson; [2022]
    Keywords : Upfront carbon; Embodied carbon; Construction emissions; Mitigation strategies; Life Cycle Assessment; LCA; Industrial facilities; Technology and Engineering;

    Abstract : For a long time, the construction and building industries have focused on increasing the efficiency of the built environment and reducing the emissions during the operations of buildings. As a consequence of the decreased operational emissions, the share of so-called embodied and upfront carbon has increased. READ MORE

  6. 5. Levelised cost of green hydrogen produced at onshore wind farm sites : A case study comparing local production in Sweden and importing from Chile

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Torun Moberg; [2022]
    Keywords : hydrogen; wind power; energy storage; ammonia; hydrogen carrier; electrolyzer; LCOH;

    Abstract : Hydrogen can be produced via water electrolysis, a process powered by electricity, and is often called green hydrogen if the electricity source is renewable. The purpose of this thesis is to investigate the levelised cost of hydrogen, LCOH, from two hypothetical scenarios of green hydrogen production at onshore wind farm sites. READ MORE
