Economic Assessment of Microalgae-Based CO₂ Utilization in Power Plant Sector in Malaysia

Abstract

Fossil fuel-fired power plants are the largest source of Carbon Dioxide (CO2) emissions. Microalgae-based Carbon Capture and Utilization (CCU) has becoming one of the promising technologies to reduce CO2 emissions due to the ability of microalgae to absorb the CO2 for photosynthesis. Integrating this technology with other CO2 mitigation practices such as co-firing biomass with coal may potentially becoming a potential solution to solve the aforementioned issue towards achieving total negative emissions. In this study, the economic potential of integrated coal-fired power plant comprising of biomass co-firing with microalgae-based CCU (Bio-CCU) is investigated.
