  1. 6. Techno-economic Optimization for Large-Scale Power-to-methane Systems : Techno-economic modeling, design and optimization of a large scale 2.0 TWh/y solar-to-methane plant concept in Australia

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Antoine Perdriel; [2021]
    Nyckelord :;

    Sammanfattning : Industrialized societies are built on the limited, extraordinary dense form of energy that are the fossil fuels: coal, oil, and gas, that became the core driver of the economic growth since the industrial revolution. While most emission pathways highlight the necessity to reach net zero emissions before 2050, there are numerous challenges to the displacement of fossil fuels by renewable energy systems (local conditions, intermittency, raw materials) and applications to the most polluting sectors such as transportation remain a major challenge.

  2. 7. High Temperature Co-Electrolysis Model for Sector Coupling : Thermodynamic and Detailed Models of Solid Oxide Electrolysis Cells and Systems

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FAISAL SEDEQI; [2020]
    Nyckelord :;

    Sammanfattning : The increased development of intermittent renewable energy supplies not only demands robust storage technology, but also alternative means to produce materials in ways to avoid fossil fuel consumption and make use of the increasing electricity supply. Power to gas (PtG) through solid oxide cell (SOC) co-electrolysis reactors provide an attractive manner to overcome both challenges. LÄS MER

  3. 8. Investigation of a CO-Production of Substitute Natural Gas and Biomethanol Plant Compared to Stand Alone Biomethanol Plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Susanne Brixland; [2019]
    Nyckelord :biomethanol; SNG; substitute natural gas; co-production; gasification; gasifier; biomass; syngas; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Sammanfattning : Climate change is one of humanities greatest challenges; the greenhouse gases in the atmosphere are still increasing. There is not one solution that will fix this problem several different products, raw material and technologies are required to take the steps towards a renewable society. LÄS MER

  4. 9. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER
