  2. 11. Combined heat and power plants in decarbonized energy systems: Techno-economics of carbon capture and flexibility services at the plant, city and regional levels

    Author : Johanna Beiron; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Negative emissions; Flexibility; CCS; District heating; Energy system modeling; Combined heat and power; Techno-economic assessment;

    Abstract : Our present energy system is the main driver of climate change. Variable renewable electricity generation and carbon dioxide removal (CDR) are key technologies in the transformation to a sustainable energy system, but their broad implementation implies challenges related to energy system flexibility and energy requirements of CDR technologies.

  4. 12. Design and Optimization of CO2 sorbents for Point Source Emissions and Direct Air Capture

    Author : Ribooga Chang; Ocean Cheung; Jean-Francois Boily; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; CO2 Sorbents; Direct Air Capture;

    Abstract : This thesis presents a comprehensive study on the design and optimization of CO2 sorbents, targeting two distinct applications: CO2 capture from point source emissions and Direct Air Capture (DAC). The research first introduces Na2HfO3 as a potential CO2 sorbent for point source emissions, using the molten salt effects of Na2CO3 and the thermal stability of HfO2. READ MORE

  5. 13. Cost-effective fuel and technology choices in the transportation sector in a future carbon constrained world: Results from the Global Energy Transition (GET) model

    Author : Maria Grahn; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy prices; CSP; CO2 emissions; hydrogen; CCS; carbon tax; biomass; carbon leakage; liquid biofuels; global energy systems modeling; transportation; passenger vehicles;

    Abstract : This thesis analyzes future fuel and technology choices focusing on transport in a carbon constrained world. The analysis tool used in all five appended papers is the cost-minimizing Global Energy Transition (GET) model. READ MORE

  6. 14. Ammonia-Based Post-Combustion Capture of Carbon Dioxide

    Author : Henrik Jilvero; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; Ammonia; Post-combustion;

    Abstract : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. READ MORE

  7. 15. Nuclear Power as a Climate Change Mitigation Option: a Modelling Approach

    Author : Mariliis Lehtveer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; sensitivity analysis; nuclear weapons proliferation; energy system model; nuclear power; climate change;

    Abstract : Although nuclear power can provide electricity with very low life cycle carbon emissions and thus reduce the cost of climate change mitigation, it also brings along many specific challenges: accident risk, need for radioactive waste management and nuclear weapons proliferation risk. Due to this controversial nature nuclear power, among other energy forms, has been relatively little studied in a climate mitigation context. READ MORE
