1. 11. 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

3. 12. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

   University essay from KTH/Materialvetenskap

   Author : Felix Göttfert; [2023]
   Keywords : Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

   Abstract : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. READ MORE

4. 13. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

   University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Author : Heba Alwan; [2023]
   Keywords : Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

   Abstract : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. READ MORE

5. 14. Study of stability improvement measures meeting the effects of new use of a secondhand cement carrier vessel

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Jansen Novri; [2022]
   Keywords : ship modification; cargo type; stability code; center of gravity; center of buoyancy; fartygsmodifiering; lasttyp; stabilitetskod; tyngdpunkt; flytkraftscentrum;

   Abstract : Secondhand ship is an option to improve marine business competitiveness. It provides a way for ship owners to integrate customer market rapidly without spending many resources on producing new ships. However, secondhand ships that perfectly suit owner's requirements becomes unavoidable challenge. READ MORE

6. 15. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques
