Koldioxidavskiljning och lagring: Vägar till negativa utsläpp

Om kursen

Emissions of CO2 and ensuing global climate change is one major societal challenge. With unchanged present emissions of about 40 GtCO2/year, the carbon budgets for the 1.5ºC and 2ºC global warming limits will be exhausted within the near future. Consequently, it is necessary to reduce CO2 emissions significantly and rapidly. Since approx. 80% of current primary energy use is based on fossil fuels, most of the IPCC emission scenarios that meet the global two-degree limit, require that carbon capture and storage (CCS) is deployed for major industrial sectors, such as heat and power and process industries.

In this course you will learn about a wide range of aspects related to carbon capture and storage. The course will include lectures, exercises, lab visit, industrial seminar and a independent project related to some interesting aspect of CCS and will be closely coupled to research.

After the completion of the course you should

  • understand the factors affecting the global carbon budgets for limiting warming to 1.5 ºC and 2.0 ºC and have knowledge of approximate
  • allowable carbon emissions in relation to current anthropogenic emissions.
  • understand the main technical and economic challenge with carbon capture processes.
  • understand the technical function of the most common carbon capture processes, and be able to describe their advantages and limitations.
  • understand the importance of heat integration for reducing capture cost in industrial processes.
  • understand how hydrogen can be generated from different energy sources and utilized as an energy carrier with no emissions of CO2.
  • understand the main features of a CO2 transportation system.
  • understand the basic geology needed for geological storage and the main mechamisms and also identify possible risks and ways to minimize these risks.
  • recognize how the structure and properties of materials at the atomic level related to their function in different CCS systems.
  • understand the main techniques proposed for achieving negative emissions, and understand how Bio-Energy with Carbon capture (BECCS) and Direct Air Capture (DAC) functions and their possibilities and challenges.
  • understand main possible strategies for utilization of CO2 in products and chemicals and the limitations of such usage.
  • understand how Life Cycle Assessment can be used to evaluate CCS/BECCS systems.
  • understand the policy-related challenges for carbon capture and bioenergy with carbon capture and storage and the level of governance these are best addressed.
  • understand how CCS/BECCS systems could be integrated into a future energy system portfolio.
  • critically evaluate and conduct research with respect to a specific challenge related to CCS and also discuss the results and implications in relation to other areas, e.g. ecological, economic, ethical, societal.

The course is composed of the following main elements,
1. Lectures (28 h)
2. Open-ended independent project within CCS and Negative Emissions
3. Industrial seminar (half-day)
4. Lab tour to CCS facilities at Chalmers
