A significant part of the cost for carbon capture and storage (CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific cases of carbon capture and utilization (CCU). In this manuscript, we investigate how much the parasitic energy of an adsorbent-based carbon c...

Since CO2 is a readily available feedstock throughout the world, the utilization of CO2 as a C1 building block for the synthesis of valuable chemicals is a highly attractive concept. However, due to its very nature of energy depleted "carbon sink", CO2 has a very low reactivity. Electrocatalysis offers the most attractive means to activate CO2 through reduction: the electron is the "cleanest" r...

Achieving a net climate benefit requires that captured CO 2 (from stack emissions, directly from air or any other source) does not return to the atmosphere. There are several negative-emissions technologies will meet this criterion. First, underground storage, possibly coupled with mineralization underground, creates essentially permanent removal. Second, can be mineralized above ground into be...

The growth of meat-spoiling Pseudomonasfragi 72 was studied on a defined salt medium supplemented with L-aspartate, citrate, creatine, creatinine, D-glucose, L-glutamate, and L-lactate. The utilization of the different carbon sources was followed in batch and continuous culture and under the influence of oxygen limitation and carbon dioxide inhibition (50% CO2 in air). Under nonrestricted atmos...

a,b-Unsaturated carboxylic acids are important chemicals, and can be used as basic materials in the production of plastics, superabsorbent, polymers, and rubbers. Various synthetic methodologies for their synthesis have been developed, for example, oxidation of propene over heterogeneous catalysts at high temperature yielded the a,b-unsaturated carboxylic acids and hydrocarboxylation of alkynes...

Sulfidogenic consortia enriched from an estuarine sediment were maintained on either 2-, 3-, or 4-chlorophenol as the only source of carbon and energy for over 5 years. The enrichment culture on 4-chlorophenol was the most active and this consortium was selected for further characterization. Utilization of chlorophenol resulted in sulfate depletion corresponding to the values expected for compl...

CO2 fi xation is a potential technology for the realization of photocatalytic CO2 reduction and synthesis of organic compounds from CO2 as a starting material. Many studies of CO2 fi xation or utilization have investigated ultra-visible light induced photocatalysis on semiconductors such as titanium dioxide1), silicon carbide1) and strontium titanate2) in heterogenous aqueous media. Biological ...

Improving our comprehension of diverse CO2 activation pathways is of vital importance for the widespread future utilization of this abundant greenhouse gas. CO2 activation by uranium(III) complexes is now relatively well understood, with oxo/carbonate formation predominating as CO2 is readily reduced to CO, but isolated thorium(III) CO2 activation is unprecedented. We show that the thorium(III)...
