Petrophysical and Mechanical Characterization of the Volcanic Rocks in the Hellisheiði Geothermal Field and implications of Thermal Fracturing in CO2 mineralization

The level of advancement in the understanding of the mechanical properties of volcanic rocks is comparatively lower than that of sedimentary rocks. As part of the SUCCEED Project (Synergetic Utilisation of CO2 Storage Coupled with Geothermal Energy Deployment), which aims to investigate the feasibility of injecting captured and produced CO2 into...

Closing the carbon cycle: Active Carbonation technology for concrete production as possible sequestration method: A TIS analysis on the Dutch concrete system

Carbon dioxide can be used during concrete production, which leads to stronger concrete as well as a sequestration method for CO2. While these technologies are developed quite far, they are currently not being used within society nor is there any systemic overview of the system and a reason why these technologies are not used. This thesis...

Effect of microstructural changes in copper during the electrochemical conversion of CO2 to hydrocarbons

Excess CO2 in the atmosphere has been a troublesome problem for humanity for the last few decades now. Academics, governments and industries are working together to tackle this problem to avert a global warming disaster. Research on many technologies is in progress to tackle global warming, with carbon capture being one exciting solution. The...

Carbon Utilization by Mineralization: Design, simulation and evaluation of a novel conceptual process

Carbon mineralization is a form of carbon utilization in which carbon dioxide is reacted with a calcium or magnesium-bearing mineral, herewith forming a carbonate. Previous research has found that mineralization shows the ability to permanently store large amounts of CO2 while at the same time delivering a product of potential added value,...

Thermodynamic, Transport and Structural Properties of Deep Eutectic Solvent Mixtures Relevant to Capture and Conversion of CO2 to Value Added Products: A Molecular Dynamics Study

The current industrial application of carbon capture utilization and storage (CCUS) is limited due to technological drawbacks such as high energy demand and environmental pollution. Ionic liquids (ILs) and deep eutectic solvents (DESs) are considered promising alternative solvents for the capture of carbon dioxide (CO2). DESs are often...

Pre-Processing of a CO₂ feedstream in a CCUS methanol microplant

When experimenting with the compression of a gas similar to the output of a CO2 Direct Air Captureunit using an off-the-shelf lubricated compressor, Zero Emission Fuels B.V.(ZEF) encountered severecondensation, damaging the compressor. This explorative study aims to identify the cause of thisproblem, create a concept solution, and test this...

Offshore transport, conditioning and storage of Carbon Dioxide: A comprehensive method to evaluate the suitability of existing offshore infrastructure for the transport and storage of carbon dioxide

This report presents the first simple and comprehensive method to effectively compare different infrastructure configurations for reservoirs that have been found suitable for long-term storage of carbon dioxide. Modelling the different transport phenomena along the chain, this study identified a fixed set of input parameters and used them to...
