  1. 11. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Sundmark; [2023]
    Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

    Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

  3. 12. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Johansson; [2023]
    Keywords : biochar; biomass; heat release rate; reaction-to-fire;

    Abstract : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. READ MORE

  4. 13. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Felix Hansen; Mathias Berglund; [2023]
    Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

    Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

  5. 14. Battery Storage as Grid Reinforcement for Peak Power Demands

    University essay from Linköpings universitet/Energisystem

    Author : Jesper Hilleberg; [2023]
    Keywords : Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

    Abstract : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

  6. 15. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Rebecca Nibelius; [2023]
    Keywords : Sodium-ion batteries; Life cycle assessment; Cradle-to-gate; Natriumbatterier; Livscykelanalys; Vagga-till-port;

    Abstract : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). READ MORE
