A call to (green) arms: a rallying cry for green chemistry and engineering for CO₂ capture, utilisation and storage

Abstract

Chemists, engineers, scientists, lend us your ears… Carbon capture, utilisation, and storage (CCUS) is among the largest challenges on the horizon and we need your help.

(Non-)Kolbe electrolysis in biomass valorization – a discussion of potential applications

“…Other possibilities involve the capture of CO 2 and further utilization as a C 1 building block. [108][109][110][111] In this regard, the electrocatalytic reduction of CO 2 112 or the thermocatalytic reverse water-gas shift 113 display two promising paths. Not yet well explored are challenges and potential opportunities of an up scaling and continuous operation.…”

“…One renewable resource hydrogen is obtained from biomass such as water, natural gas, crude oils, hydrocarbon, and organic fossil materials. Recently glycerin has become increasingly available as a by-product of the manufacture of bio-diesel, and this renewable feedstock has improved the production of epichlorohydrin, a largely used chemical for the manufacture of epoxy resins 25 . Some other solvents which can be distilled, purified, and reused such as acetone, methanol, ethanol, acetonitrile, etc.…”

Encapsulated Amino‐Acid‐Based Ionic Liquids for CO2 Capture

“…Post‐combustion stands as the most appealing emission sources due to an easy retrofit of existent and new technologies into existing power plants. Although gas separation has long been used in natural gas industry, counterbalanced by the increased value of the post‐treated streams, post‐combustion is still seen as a non‐efficient, costly and, ultimately, unfeasible process …”

“…Furthermore, envisioning the use of green solvents is indispensable for a clean energy production, anthropogenic CO 2 capture, transportation, and/or reconstitution into value‐added products. Nonetheless, if one aims at developing a technical and economically viable process for carbon capture, the pursuit on improving CO 2 solubility, viscosity, heat capacity and mass transfer of sorbents must be addressed from a process engineering perspective, as highlighted by Leclaire and Heldebrant in their recent “ call to arms ” perspective . As emphasized by the authors, the community should shift focus from just enhancing equilibrium capacity to focus on the principles of green chemistry and green engineering, to make Carbon Capture, Utilization and Storage (CCUS) a reality.…”
