  1. 1. Optimization of battery pack assembly of second life cells to reduce costs

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

    Author : Akash Prasad Chowdry; [2022]
    Keywords : Batteries; second life cells; active cell balancing; lossless cell balancing; off-grid solar; solar home systems; Batterier; second life cells; aktiv cellbalansering; förlustfri cellbalansering; solceller utanför nätet; solcellssystem för hemmabruk.;

    Abstract : Batteries account for 50% of the overall cost of solar home systems (SHS). The battery packs degrade over time and when they reach 70% state of health (SOH), the whole SHS is discarded. In the predominantly rural off-grid context, battery replacements are expensive and impractical. The customers are often dozens of km away from any sales point. READ MORE

  3. 2. Recycling Waste Solar Panels (c-Si & CdTe) in Sweden

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Alireza Nekouaslazadeh; [2021]
    Keywords : PV panels; Environmental impacts; Economical impacts; c-Si; CdTe; Solar modules recycling center; Critical materials; Delamination; Material separation;

    Abstract : Solar energy industries are one of the fastest-growing industries in the global energy market. Between 2018 and 2019, installed capacity in Sweden increased by 70%. This is due to a combination of declining PV module and inverter costs, as well as  increased conversion to fossil-free energy production to mitigate greenhouse gas emissions. READ MORE

  5. 4. Validation of MP-AES at the Quantification of Trace Metals in Heavy Matrices with Comparison of Performance to ICP-MS

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Isabelle Berg; [2015]
    Keywords : MP-AES; ICP-MS; high matrices; digestion; microwave plasma; combustion ash; ion exchange;

    Abstract : The MP-AES 4200 using microwave plasma and an atomic emission spectroscopy detector provide a new and improved instrument to the analytical field. In this project will the performance of the equipment be evaluated in controlled NaCl-heavy matrices for selected metals (Cu, Zn, Li) and the result from this will be used to optimize a method for specific samples.

  6. 5. Hydrogen production in Escherichia coli : Genetic engineering of the formate hydrogenlyase complex

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Charlotte Hjersing; [2011]
    Keywords : Escherichia coli; Formate hydrogenlyase; Hydrogenase; Oxygen tolerance;

    Abstract : Biofuels that are renewable and environmentally benign constitute an important area of research, as the supply of fossil fuels decreases and the amount of green house gases in the atmosphere increases. Biohydrogen is not as well explored as other biofuels, but its properties render it a promising complement, as it is clean and can be used directly in fuel cells to generate electricity, the only waste products being water and heat.
