“…Converting CO 2 into fuels and high value-added chemicals has attracted significant worldwide interest in the past few years, as it not only contributes to mitigating greenhouse gas emissions but also produces valuable chemical commodities [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] . As such, CO 2 conversion and utilization should be taken both an integral and important part of greenhouse gas control and sustainable development.…”

With mounting concerns over climate change, the utilisation or conversion of carbon dioxide into sustainable, synthetic hydrocarbons fuels, most notably for transportation purposes, continues to attract worldwide interest. This is particularly true in the search for sustainable or renewable aviation fuels. These offer considerable potential since, instead of consuming fossil crude oil, the fuels are produced from carbon dioxide using sustainable renewable hydrogen and energy. We report here a synthetic protocol to the fixation of carbon dioxide by converting it directly into aviation jet fuel using novel, inexpensive iron-based catalysts. We prepare the Fe-Mn-K catalyst by the so-called Organic Combustion Method, and the catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). The conversion reaction also produces light olefins ethylene, propylene, and butenes, totalling a yield of 8.7%, which are important raw materials for the petrochemical industry and are presently also only obtained from fossil crude oil. As this carbon dioxide is extracted from air, and re-emitted from jet fuels when combusted in flight, the overall effect is a carbon-neutral fuel. This contrasts with jet fuels produced from hydrocarbon fossil sources where the combustion process unlocks the fossil carbon and places it into the atmosphere, in longevity, as aerial carbon - carbon dioxide.

“…The Carbon Capture Storage (CCS) technology is fast developing, and the potential of producing synthetic fuels from the captured carbon is exciting [2,14,28]. The CCS technology currently relies on temperature swing adsorption using amine [29]. Studies, however, are on to advance the knowledge of cryogenics, membrane separation, and algae-based systems that can be adopted in the nearest future [28].…”

The future of internal combustion engine-powered automobiles hangs in the balance unless clean fuels are available in commercial quantities. Electricity-powered vehicles will displace the internal combustion engine-powered automobiles. However, electricity-powered vehicles are yet to meet some of the automobile demands. A paradigm shift with attendant infrastructural change is necessary for its adoption. Synthetic fuels promise to be the solution. Their invention dates back to the early twentieth century when the concern was not about climate change. The search for alternative fuels later metamorphosed to when fossil fuels reserve depletion and petroleum derivatives cost became a concern. The alternatives were made available in biofuels. The prevailing challenge is now climate change. It is the consequence of the emission of greenhouse gases from the combustion of petroleum derivatives in automobiles. Synthetic fuels show the potential of coming to the rescue despite the prevailing hurdles. The future holds a potential promise of converting greenhouse gas (CO2) to liquid fuels that will allow little or no disruptions to the current transportation infrastructure network. It is, therefore, necessary to encourage further studies on the production of synthetic fuels. The environmental and economic benefits of commercially available synthetic fuels promise to be enormous.

“…Continuously converting the fossilized carbon into atmospheric CO 2 through expeditious extraction and consumption has left the carbon loop unbalancd leading to adverse climate changes and a dearth of raw material (fossils) (Hoornweg et al, 2013;Dowson and Styring, 2017). With substantial increase in the world population, need for sustainable feedstocks has also increased.…”

Microalgae are most versatile organisms having ability to grow under diverse conditions and utilize both organic and inorganic carbon sources. Microalgal photosynthesis can be employed to transform carbon dioxide (CO 2 ) into essential bioactives and photofuels. In this study, microalgal growth under modified headspace gas compositions which are CO 2 + H 2 (1:1), CO 2 , H 2 and Air was evaluated to determine the photosynthetic efficiency and bioactives production. A marked enhancement was observed in quantum yield (Fv/Fm: 0.77) and CO 2 biosequestration rate (0.39 g.L −1. d −1 ) under CO 2 + H 2 headspace gas condition as compared to the other experimental variations. The chemoselective functioning of Rubisco under varying gas concentrations was determined, where elevated CO 2 conditions negate the oxygenase activity under a high CO 2 /O 2 ratio which enabled higher CO 2 sequestration. The enhanced CO 2 sequestration and altered redox conditions through H 2 addition under the monophasic operation have also led to a higher average degree of unsaturation (DU) and carbon chain length (CCL) of the fatty acids produced. This study provides an approach to augment photosynthetic efficiency and lipogenesis through non-genetic modifications along with the feasibility to cultivate microalgae in integration with industrial flue gases. Exploiting the true potential of microalgae would provide sustenance from climatic changes and environmental pollution concurrently producing biobased products analogous to the fossil-derived products.
