  1. 21. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

    University essay from Uppsala universitet/Datalogi

    Author : Lovisa Olsson; Julia Hellström; [2023]
    Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

    Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE

  3. 22. Evaluating electrolyser setups for hydrogen production from offshore wind power : A case study in the Baltic Sea

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

    Author : Kenzo Franzén; [2023]
    Keywords : electrolysis; energy systems modelling; green hydrogen; offshore wind power; power-to-x; electrólisis; energía eólica marina; hidrógeno verde; modelado de sistemas de energía; power-to-x;

    Abstract : As part of the transition towards a fully sustainable energy system, green hydrogen shows great potential to decarbonise several hard-to-abate sectors. To provide the fossil-free electricity required for electrolysis, offshore wind power has emerged as a suggested option. READ MORE

  4. 23. Offshore Hydrogen Production and Storage for Wave Energy Application : A Techno-Economic Assessment for a Japanese Context

    Abstract : There is a well-established market for hydrogen, mainly for refining purposes, producing chemicals, and producing fertilizers. Today, almost all hydrogen is sourced from fossil fuels, with less than 1% of hydrogen sourced from renewable sources. READ MORE

  5. 24. Permanently stored, permanently trapped? A study on the risk of carbon lock-in through the German-Norwegian partnership in CCS and hydrogen

    University essay from Lunds universitet/LUCSUS

    Author : Lena Faber; [2023]
    Keywords : CCS; carbon lock-in; blue hydrogen; climate change mitigation; sustainability science; Social Sciences;

    Abstract : As the climate crisis becomes more severe, carbon capture and storage (CCS) is increasingly seen as a viable option to help mitigate climate change. However, one risk with regard to CCS is that it locks us into the use of carbon-based energy sources and industry, creating a carbon lock-in. READ MORE

  6. 25. Defossilise Väster – Testing a fossil free urbanity for the debate

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö
