Understanding carbon dioxide transport in porous media and microalgae growth dynamics is essential for advancing carbon sequestration and biofuel production. Traditional methods, relying on bulk-scale experiments and computational modelling, lack the precision to observe microscale interactions in real-time. We propose developing microfluidic platforms to address these limitations. One platform will enable direct visualization of CO₂ movement in porous structures, providing insights into pore-scale transport mechanisms and their impact on storage efficiency. The other will facilitate controlled microscale culturing of Euglena sp., allowing precise investigation of environmental factors such as light, pH, temperature, nutrient concentration, and CO₂ absorption on growth dynamics. These microfluidic systems will enhance our understanding of carbon sequestration efficiency and optimal conditions for biomass production, contributing to sustainable energy and climate mitigation strategies.
