“…The second strategy (ii) is based on an advanced approach of co-processing CO 2 and water to produce fuels without intermediate H 2 production [ 16 ]. Such an approach has the great advantage of cutting the costs of producing, storing, transporting, and using H 2 , resulting in a much lower CAPEX, and even a lower OPEX, in terms of the safety measures to be implemented.…”

“…Such an approach has the great advantage of cutting the costs of producing, storing, transporting, and using H 2 , resulting in a much lower CAPEX, and even a lower OPEX, in terms of the safety measures to be implemented. A more probable approach is to use the Sun to power direct photochemical, photoelectrochemical, photobiochemical, and photobioelectrochemical routes of CO 2 reduction and water oxidation [ 15 ], producing fuels that can be called solar fuels for simplicity [ 16 ]. The TRL of such technology is very low (2–3), but of great interest for the future.…”

This paper discusses the epochal change in the reputation of carbon dioxide, which is now considered as a raw material alternative to fossil C for the synthesis of chemicals, materials and fuels, as opposed to a waste material that must be confined underground. In particular, its use as renewable C is compared to biomass. In this paper, a specific point is discussed: is ethanol (or any fuel) produced via the catalytic conversion of atmospheric CO2 different from the relevant biomass-sourced product(s)? The answer to this question is very important because it ultimately determines whether or not fuels derived from atmospheric CO2 (either e-fuels or solar fuels) have the right to be subsidized in the same way that biofuels are. Conclusions are drawn demonstrating that ethanol derived from atmospheric CO2 deserves the same benefits as bio-ethanol, with the additional advantage that its synthesis can be less pollutant than its production via the fermentation of sugars. The same concept can be applied to any fuel derived from atmospheric CO2.

“…An attractive case of CO 2 utilization is the biotechnological reduction of CO 2 to methanol [ 8 , 9 , 10 , 11 , 12 ] ( Figure 1 ), which has multiple uses as a raw chemical and fuel. This reaction has aroused much interest, and in recent years, several research groups have tried to take stock of much research efforts: reviews describing particular aspects of the reaction condition can be found in the literature [ 13 , 14 , 15 ].…”

The need to decrease the concentration of CO2 in the atmosphere has led to the search for strategies to reuse such molecule as a building block for chemicals and materials or a source of carbon for fuels. The enzymatic cascade of reactions that produce the reduction of CO2 to methanol seems to be a very attractive way of reusing CO2; however, it is still far away from a potential industrial application. In this review, a summary was made of all the advances that have been made in research on such a process, particularly on two salient points: enzyme immobilization and cofactor regeneration. A brief overview of the process is initially given, with a focus on the enzymes and the cofactor, followed by a discussion of all the advances that have been made in research, on the two salient points reported above. In particular, the enzymatic regeneration of NADH is compared to the chemical, electrochemical, and photochemical conversion of NAD+ into NADH. The enzymatic regeneration, while being the most used, has several drawbacks in the cost and life of enzymes that suggest attempting alternative solutions. The reduction in the amount of NADH used (by converting CO2 electrochemically into formate) or even the substitution of NADH with less expensive mimetic molecules is discussed in the text. Such an approach is part of the attempt made to take stock of the situation and identify the points on which work still needs to be conducted to reach an exploitation level of the entire process.

This paper tells the recent history of CO2 chemistry through the contributions from members of CIRCC to its birth and growth. Starting with the first transition metal complex bearing CO2 as a ligand synthesized in 1975 by the Aresta Group in Bari, the mode of bonding and the reactivity of coordinated CO2 are discussed. The early applications in chemo‐thermal, electrolytic, and biotechnological processes, and the use of SC‐CO2 as solvent and reagent are fields in which CIRCC partners have made pioneering contributions and continue to provide essential inputs. The paper is closed by highlighting key issues and challenges at stake, from capture to large‐scale conversion, investment infrastructure, progressive policies and standardized regulations needed to advocate carbon recycling as a pillar of future innovation in energy and chemical industries. CIRCC has been the nest of modern CO2 chemistry and the place where CO2 has always been considered a “resource” rather than a “waste”.
