With increasing global energy consumption and need for smart, cleaner electricity, the
world demands responsible power generation. The majority of the world primary power generation
is still based on fossil fuels which contributes to increasing greenhouse gas emissions and
consequent climate change. Integration of solar energy with fossil fuel-based power plants is an
effective solution that can mitigate carbon emissions.
Post-combustion carbon capture is one of the promising technologies that mitigates carbon
dioxide (CO2) emissions, but it has associated with it, heat and electricity requirements for the CO2
capture process and the CO2 compression systems. In solvent-based carbon capture systems, the
required thermal energy is always extracted from low-pressure steam from the power plant to meet
the reboiler duty in the carbon capture reboiler. This results in a decrease in unit efficiency and
power generation. A possible way to overcome this drawback is by employing solar-assisted post
combustion carbon capture which would significantly compensate on the power plant due to
absorbent regeneration. In this approach, a solar thermal system is integrated with an amine-based
carbon capture process.
This study focused conducting a preliminary design on how to couple a concentrated solar
thermal plant to carbon capture pilot-scale plant in Mexico. This thesis also discusses the
advantages of the methodology to get the optimal results of the coupling. This further provides
guidance on the possible ways to fully design and integrate solar thermal energy with post-carbon
