CO2utilization: an enabling element to move to a resource- and energy-efficient chemical and fuel production

CO 2 conversion will be at the core of the future of low-carbon chemical and energy industry. This review gives a glimpse into the possibilities in this field by discussing (i) CO 2 circular economy and its impact on the chemical and energy value chain, (ii) the role of CO 2 in a future scenario of chemical industry, (iii) new routes for CO 2 utilization, including emerging biotechnology routes, (iv) the technology roadmap for CO 2 chemical utilization, (v) the introduction of renewable energy in the chemical production chain through CO 2 utilization, and (vi) CO 2 as a suitable C-source to move to a low-carbon chemical industry, discussing in particular syngas and light olefin production from CO 2 . There are thus many stimulating possibilities offered by using CO 2 and this review shows this new perspective on CO 2 at the industrial, societal and scientific levels.
