Methanol production from renewable sources: A techno-economic assessment

The urgency of taking actions against climate crisis is unprecedented. The human-produced CO2 is the largest contributor to global warming, which drives the climate change. Many countries around the world have committed to net-zero greenhouse gas emissions in the next coming decades. Power-to-X (PtX) technologies in combination with carbon...

Modelling and Numerical Investigation of Taylor Flow on the Performance of Electrochemical Flow Cells

Electrochemical reduction of CO2 using renewable energy sources is one of the promising avenues to pursue towards mitigating the emissions of the notorious CO2. However, the CO2 electrolysis in aqueous systems, due to the low solubility of CO2, are severely limited by mass transfer. State of the art review shows that a significant amount of the...

Electrochemical synthesis of CO2-methanol utilizing direct air capture, CO2 electrolysis and H2O electrolysis: A life cycle assessment

This thesis examines the production of an alternative liquid hydrocarbon fuel, namely CO2-methanol, produced utilising DAC, CO2 electrolysis, H2O electrolysis and thermo-catalytic synthesis. The reason for such research lies in a persistent growth in global energy demand, a significant share of which comes from liquid fuels, in the present...

Optimizing the design of a CO2 electrolyser for producing formate to improve flow distribution and gas bubble flow: Experimental and numerical investigation of several designs

The worlds energy demand is rising as a result of industrial activity and advances in countries around the world. Fossil fuel sources are used to meet this demand for much of the world [1]. The way in which energy is handled causes pollution e.g., CO2 emissions, inducing climate change, therefore a more sustainable industry is desired [2, 3]....

Electrochemical Reduction of CO2 to CO in Membrane Electrode Assembly (MEA) Setup

The global concern of the increasing levels of CO2 is growing quickly in the recent years. Therefore, a lot of research is currently underway with respect to closing the carbon cycle. The electrochemical reduction of CO2 is a promising technology that could help utilize the CO2 as a feedstock to produce chemicals and fuels, while storing the...

Addressing The Potential of Alternative Configurations for CO2ER Supply Chains

As global climate change concerns intensify, the search for renewable-based alternatives to products and processes that rely on fossil fuels becomes ever more important. A process that has been championed is the co-electrolysis of carbon dioxide and water, under the supply of renewable energy, via high-temperature solid oxide electrolyser...
