CCS Reservoir Simulation using Graph Neural Networks: Building ML solutions for efficient CO2 subsurface modelling

Reducing cost and improving computability of reservoir simulation is an important goal in the process of enabling CCS (Carbon Capture \& Storage) as a large-scale technology for mitigating CO2 emissions. In terms of computation time data-driven approaches have potential to outweigh the performance of numerical reservoir simulators, learning...

CCS: A Framework for Development: A Policy and Project-oriented Framework for the Evaluation of Integrated Carbon Capture and Storage (CCS) Projects; a Case Study Approach

As the world grapples with the escalating challenges of climate change, Carbon Capture and Storage (CCS) emerges as a crucial solution, especially for decarbonizing dominant industries such as steel, cement, and petrochemicals. The Intergovernmental Panel of Climate Change (IPCC) and the International Energy Agency (IEA) have highlighted the...

Evaluation of carbon reduction options in industrial combined heat and power plants

Industry is a major contributor to the rise in global CO2 emissions, constituting one fifth of the global energy consumption, of which significant amount is provided by fossil fuel combustion. Following the Paris agreement, emphasis has been made on decarbonization of the industrial sector. This thesis focuses on industrial decarbonization by...

The artificial carbon sink: Using products to fight climate change

This project considers the implications of carbon-negative materials in product design. It speculates on a future where decarbonization of different sectors of the economy increases the ubiquity of carbon-negative materials. Under these conditions, certain materials become a source of negative emissions, and their consumption benefits the planet...

The economic competitiveness of green hydrogen based on its alternatives for the Dutch industry: A comprehensive overview of the cost development of green hydrogen alternatives in the Dutch process industry from 2021 to 2050

As the energy transition is starting to accelerate, the Dutch industrial sector is in danger of falling behind with its decarbonisation efforts. Green hydrogen is often suggested as a key-player to decarbonize the industry, replacing fossil fuels used for process heat generation as well as in hydrogen feedstock production. As there are an...

Syngas Purification: Design of a Rectisol® based purification plant for the removal of impurities and simultaneous capture of CO₂ from the works arising gases of an integrated steel mill

The steel making industry is highly energy intensive and a great contributor of greenhouse gas (GHG) emissions. It generated between 7% and 9% of direct emissions from the global use of fossil fuels in 2017 [1]. Gas emissions in an integrated steel mill (ISM) arise mainly from three streams: coke oven gas (COG), blast furnace gas (BFG) and basic...

An improved carbon dioxide thermodynamic model applied for reservoir simulation: Implementation of an improved thermodynamic model in Delft Advanced Terra Simulator (DARTS) and an investigation into the effects of impurities on gas plume behaviour

Geological storage of COኼ is a crucial and upcoming technology to reduce anthropogenic greenhouse gas emissions. Due to the buoyant characteristic of injected gas, the security of underground storage is a major concern. To asses the security of COኼ storage, an accurate prediction of the gas plume behaviour is essential. In this study, a fully...

Optimization Strategies of CO2 Injection for Sequestration and EOR

The current situation with green gas emission requires the development of low carbon energy solutions. However, a significant part of the modern energy industry still relies on fossil fuels. To combine these two contradictory targets, we investigate a strategy based on a combination of CO2 sequestration with Enhanced Oil Recovery (EOR) in the...

Power To Paris: The Role of Carbon Capture and Storage in a Future European Electricity System that Abides by the COP21 Climate Agreement

To limit global warming to 2 degrees Celsius in 2100, the European power sector needs to transform. Renewable energy capacity is required to reach this ambition, together with transmission and storage capacity to maintain grid stability. Carbon capture and storage could potentially decrease the required renewable energy capacity, while...
