Carbon Capture and Utilization (CCU) technologies have been proposed as a means to mitigate greenhouse gas emissions from fossil fuel plants in São Tomé and Príncipe, a small archipelago off the west coast of Central Africa. Qualitative methods were employed, including semi-structured interviews and participant observation in fossil fuel plants and surrounding areas. Data was analysed using thematic analysis. Interviews revealed that local communities have a nuanced understanding of CCUS technologies, with some viewing them as potential sources of employment and revenue, while others are concerned about environmental impacts and technological complexity. The study highlights the importance of community engagement in assessing CCU technology adoption. Future research should incorporate these insights into policy frameworks for sustainable energy development. Local authorities should prioritise stakeholder dialogue to address concerns and facilitate acceptance of CCUS technologies, while researchers need to develop more interactive educational materials for communities.
