  1. 1. Techno-Economic Assessment of High-Temperature H2O/CO2 : Co-Electrolysis in Solid Oxide Electrolysers for Syngas Production

    University essay from KTH/Kemiteknik

    Author : Shivani Ramprasad Jambur; [2022]
    Keywords : Co-electrolysis; Power-to-X; Process modeling; Green Syngas; Solid-Oxide Electrolyser;

    Abstract : High-temperature Co-electrolysis of H2O and CO2 in a solid-oxide electrolyser (Co-SOE) for syngas production is a high-efficiency renewable electricity conversion and storage method part of the Power-to-X technologies. Syngas, a mixture of H2, CO and CO2, is a critical building block to make several chemical and synthesis fuels. READ MORE

  3. 2. System concept for small-scale biological methanation using electrolysis and trickle bed reactor : with the aim of upgrading biogas to vehicle fuel quality

    University essay from SLU/Dept. of Energy and Technology

    Author : Gustav Larsson; [2021]
    Keywords : biological methanation; biogas upgrade; methane; small-scale methanation;

    Abstract : In the present study, the concept of a biological H2 methanation (BHM) system was created for four cases of scale which are determined by electrolyser scale. The system design is aimed to upgrade existing biogas to vehicle fuel quality, with a concentration of CH4 above 95% and H2S removal. The cases of scale and type of electrolyser are: 4. READ MORE

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

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

    Author : FAISAL SEDEQI; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

    Keywords : biomethanol; SNG; substitute natural gas; co-production; gasification; gasifier; biomass; syngas; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Abstract : 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. READ MORE

  6. 5. Comparison of different reactor configurations for ex‐situ biological biogas upgrading

    University essay from Linköpings universitet/Energisystem

    Author : Hugo Porté Laborde; [2016]
    Keywords : ;

    Abstract : Climate change is one of the major challenges of the 21st century. The energy sector represents the main contributor to global greenhouse gas emissions, due to its reliance on fossil fuels. Renewable energies arise as current solutions. READ MORE
