  1. 21. How Has the Current Electricity Crisis in South Africa Affected the Development of Renewable Energy within the Independent Power Producer Procurement Programmes?

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Sophie Jahns; [2023]
    Keywords : South Africa; Electricity Crisis; Energy Insecurity; Renewables; IPP; Eskom; Business and Economics;

    Abstract : This thesis examines the effects of South Africa’s electricity crisis on the government-driven development of renewable energy from 2007 to 2023 by testing the applicability of the energy security framework. The electricity crisis presents itself through regular electricity cuts, extreme power tariff rises and a lack of long-term sustainability due to the high reliance on coal and Eskom, the monopolistic electricity utility.

  3. 22. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

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

    Author : Robert Liao; [2023]
    Keywords : ;

    Abstract : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  4. 23. Impact of offtake mechanisms on wind turbine selection and design in North and Central Europe

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

    Author : Gesa Reiter; [2023]
    Keywords : Wind energy; offtake mechanisms; wind turbine configuration and design; rated power; capacity factor; Renewable Energy Sources Act; EEG; PPA; merchant; profitability; NPV; IRR; Vindkraft; upphandlingsmekanismer; vindturbiners konfiguration och utformning; nominell effekt; kapacitetsfaktor; lagen om förnybara energikällor; EEG; energiköpsavtal; handelsprissättning; lönsamhet; NPV; IRR;

    Abstract : Wind power has become a major supplier of electricity in the European market in the last years. In 2020, 13% of electricity generated on the European continent was wind energy (onshore and offshore) and these shares are projected to increase in the next years due to reasons such as climate change and the energy security aspect.

  5. 24. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Hanna Grahn; Matilda Eriksson; [2023]
    Keywords : Large-scale heat pump; refrigerant; COP;

    Abstract : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

  6. 25. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jean-Pierre Hamzo; [2023]
    Keywords : CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Abstract : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. READ MORE
