The escalating atmospheric concentrations of carbon dioxide (CO2) due to human pursuit which includes fossil fuel combustion, deforestation, and industrial production make contributions considerably international warming climate change. Carbon capture storage (CCS) usage (CCU) technology provide viable solutions for mitigating those emissions. This paper critiques various CCS CCU techniques that specialize their ability applications, stressful situations, environmental impacts. While technologies promising consequences in decreasing capability, they're associated with better acidification toxicity comparison standard techniques. Alternatively, present an opportunity convert CO2 into valuable products, thereby imparting a sustainable approach greenhouse gas reduction. But, these face challenges consisting high expenses, energy consequences, the need social recognition. study provides comprehensive assessment modern technologies, evaluates affects, discusses future prospects implementation reducing

Development of an Effective Microalgae Cultivation System Utilizing CO2 in the Air by Injecting CaCO3

Energies, Journal Year: 2024, Volume and Issue: 17(17), P. 4475 - 4475

Published: Sept. 6, 2024

Recognized as the third-generation biomass of future, microalgae are increasingly viewed a promising solution for sustainable production biofuels, often referred to “green gold.” Extensive research is being conducted across upstream, midstream, and downstream sectors develop fundamental technologies that enable efficient economical large-scale cultivation. Recent studies suggest microalgae-based biofuels have potential meet global energy demands. However, challenges such spatial constraints in site selection high cost transporting CO2—an essential component pH regulation photosynthesis—pose obstacles. Here, this study demonstrates by supplementing air-only medium with CaCO3, Chlorella sorokiniana can effectively utilize airborne CO2 produce biomass. In laboratory-scale culture conditions supplied only air, adding 5 mM CaCO3 (pH 7.8) could maintain stably compared untreated 9.5) improved concentration lipid content 17.68-fold 9.58-fold, respectively. bench-scale conditions, cultures supplemented exhibited 9-fold increase 7.15-fold concentrations those cultivated air alone. With emerging an resource future generations, cultivation technology utilizing will be critical enables commercial-scale using without artificial supply facilities.

Tackling Old Challenges in Microalgal Biotechnology: The Role of Photobioreactors to Advance the Technology Readiness Level

Processes, Journal Year: 2024, Volume and Issue: 13(1), P. 51 - 51

Published: Dec. 29, 2024

Microalgae biotechnology has taken the world by storm. However, despite its great potential promise, it still cannot be considered a fully consolidated technology due to crucial challenge: low rates of biomass productivity. To overcome this hurdle, photobioreactors have been developed as an innovative solution, promising increase efficiency microalgae cultures providing optimized conditions. results obtained with these systems do not always meet initial expectations, and their large-scale implementation faces complex technical challenges. In light this, present review addresses main aspects related design engineering photobioreactors, highlighting potentialities limitations in overcoming critical challenges microalgal biotechnology. Furthermore, we discuss current technological readiness level commercial index microalgae-based bioproducts from perspective industrial-scale production.
