“…In the same sense, biochemical conversion utilizes enzymes or microbial catalysts to convert CO 2 and water to various products such as methane, methanol, CO, and biomass . The most promising species include spirulina microalgae, cyanobacteria, and carbonic anhydrase, , with the efficiency of the process being reliant on the organism and its growth rate, tolerance for contamination, and control of operating condition.…”

CO 2 can be converted into value-added products such as fuels, chemicals, and building materials, adding an economic incentive for CO 2 capture and green economy, while also reducing the environmental footprint of hard-to-abate industries such as aviation, construction, and metallurgy. Nonetheless, most available technologies for direct CO 2 conversion, while promising, are still in early development stages, facing technical and economic challenges for their scale-up, questioning their viability to truly instill a timely impact on global CO 2 emissions. Furthermore, a clear environmental benefit should be obtained for the new processes versus the traditional ones they are replacing in the market. In this perspective, we examine the range of available technologies for direct CO 2 conversion using thermal, electrical, and photochemical routes and mineralization including the advancements in their role in synthesizing a range of resulting products from methanol, methane, carbon monoxide, and solid carbonates. We offer insights on the trends in current research and development and the required direction to expedite the technological readiness of attractive CO 2 conversion technologies in terms of catalytic material and reactor design. We also highlight the important role of modeling (molecular and process levels) as an enabling tool to deploy these technologies at the commercial scale originating from understanding their behavior at the molecular level. Lastly, we highlight the significance of carrying out reliable life cycle analysis in identifying the environmental hotspots as well as gaps in the technology that allows improving their environmental footprint and economic attractiveness.

“…Carbon sequestration methodologies such as biotic carbon sequestration and abiotic/geological carbon sequestration methods have been studied in the recent past. − Carbon sequestration through biomass-producing plants in wetlands, terrestrial, biota and aquatic regions are some of the biotic carbon sequestration methods. Moreover, biotic carbon sequestration routes are not just cost-efficacious and sustainable but also produce value-integrated products such as biodiesel, bio-oils, bioethanol, biomethanol, and dimethyl ether. ,− In recent years, scientists have converted CO 2 into antioxidants, biochemicals and biofertilizers through different metabolic pathways in the presence of different heterotrophic and autotrophic microorganisms. − Even though soil and microbial carbon sequestration are highly effective, the rate of CO 2 fixation is low, and it requires a lot of soil and the entire life cycle to fix CO 2 . Abiotic or geological carbon sequestration methods are also utilized for carbon sequestration in depleted oil and natural gas reservoirs.…”

Immediate measures are required to tackle global warming and climate change that may require the storage of enormous quantities of anthropogenic CO2 in geological and oceanic reservoirs. In terrestrial storage sites, CO2 is buoyant due to the subsurface temperature profile. Therefore, if the reservoir is not adequately sealed, stored CO2 can escape from geological formations. Alternatively, oceanic sequestration has immense potential to facilitate long-term sequestration of CO2 beneath the seafloor, thereby assisting the wider scientific and industrial community to make the world carbon neutral. There is a far-reaching scope for discussion in this aspect that will open up new avenues for future developments in this area. This article discusses the long-term viability, environmental sustainability and economic potential of CO2 sequestration in the form of hydrates into oceanic and subsea sediments. Analysis shows that at above 2800 m depth, CO2 is denser than seawater, which offers an additional gravitation barrier for CO2 to escape. This article offers an in-depth analysis of CO2 sequestration conditions, along with challenges and outlook with relevance to hydrate-based CO2 sequestration in oceanic conditions. Moreover, the crucial role of negative buoyancy and hydrate-forming zones (NBZ/HFZs) and analysis of depth criterion in oceanic conditions have been highlighted. The review also envisages that sequestration in NBZ region offers stable storage for years even in geological perturbation and earthquakes; however the depth of HFZ and NBZ regions depends on sedimentary type, storage conditions, temperature and pressure.
