Carbon Capture and Energy Storage

Exploring the innovative intersection of technology and environmental science, this bachelor's thesis delves into the critical areas of Carbon Capture and Energy Storage (CCES). It addresses the escalating concern of atmospheric CO2 levels by presenting a comprehensive analysis of carbon capture methods and energy storage solutions. Through a blend of theoretical research and practical modelling, this thesis contributes to the ongoing dialogue on sustainable energy practices by developing a functional model capable of generating electricity from compressed air that simulates compressed CO2.

The research adopts a multifaceted approach, using both qualitative and quantitative methods to investigate Carbon Capture and Storage (CCS) technologies alongside Compressed Air Energy Storage (CAES) systems. Through the integration of theoretical analysis and the construction of a functional energy storage model, the thesis provides a thorough examination of the technological and economic aspects of CCS. This includes the investigation of different CO2 capture techniques - post-combustion, oxyfuel combustion and pre-combustion - and their impact on energy efficiency and environmental impact. The practical component also involved the design and optimisation of a centrifugal compressor in Python, using a genetic algorithm to improve the overall efficiency of the model.
The results demonstrate the feasibility and scalability of CCS and CAES technologies as viable solutions for reducing greenhouse gas emissions and promoting renewable energy storage. The research highlights the potential of CCS to mitigate climate change by effectively capturing and storing CO2 emissions from industrial sources. In addition, the functional CAES model demonstrates a promising approach to energy storage that addresses the intermittency issues associated with renewable energy sources. Finally, it is worth noting that the model was constructed using a self-assembled 3D printer and CNC machine.
