In recent years, we have experienced significant increases in greenhouse gas emissions and with this, weface grave consequences worldwide. Transitioning to renewable energy is essential but to be fully effectiveat reducing GHG emissions from very hard to decarbonise industries, deployment of additionaltechnologies like carbon capture technology will also be required. Microalgal growing systems are anotherviable carbon capture technology due to their very high capture rates and ability to grow in many differenttypes of conditions. Microalgal growing systems have a lot of potential to mitigate climate change and arean effective and sustainable method of sequestering CO2 on a large scale. Therefore, in order to optimizemicroalgae's CO2 capture efficiency, key factors such as light levels, pH, temperature, availability ofnutrients and strain selection must be considered. Photobioreactors with advanced configurations, includingflat-plate designs with PIAT internals and sequential-flow bubble column reactors, will have greater CO2absorption and biomass productivity than traditional photobioreactors. The reduction of CO2 in theatmosphere globally can be facilitated by successfully resolving key issues related to reactor optimization,CO2 delivery, and strain performance of microalgae, complemented by genetic engineering and theapplication of carbonic anhydrase enzymatic solutions. For this reason, continuous research and innovationare critical to realizing the benefits of microalgae for climate change mitigation and as a potential green andrenewable means of advancing to a sustainable future. This research project examines optimization methodsfor algal systems for effective direct air capture (DAC) from biological, technological, and economicperspectives
