“…7 DACCS systems offer some flexibility compared to other CDR technologies, since they can remove CO 2 independently from point sources, both in time and space. 6,8 Consequently, optimal locations can be selected, considering CO 2 storage potential and local costs for energy supply. 9 DAC systems are usually based either on aqueous solutions with High Temperature regeneration (HT DAC), or on solid sorbents with Low Temperature regeneration (LT DAC).…”

Prospective energy scenarios usually rely on Carbon Dioxide Removal (CDR) technologies to achieve the climate goals of the Paris Agreement. CDR technologies aim at removing CO2 from the atmosphere in a permanent way. However, the implementation of CDR technologies typically comes along with unintended environmental side-effects such as land transformation or water consumption. These need to be quantified before large-scale implementation of any CDR option by means of Life Cycle Assessment (LCA). Direct Air Carbon Capture and Storage (DACCS) is considered to be among the CDR technologies closest to large-scale implementation, since first pilot and demonstration units have been installed and interactions with the environment are less complex than for biomass related CDR options. However, only very few LCA studies - with limited scope - have been conducted so far to determine the overall life-cycle environmental performance of DACCS. We provide a comprehensive LCA of different low temperature DACCS configurations - pertaining to solid sorbent-based technology - including a global and prospective analysis.

Closing the carbon-, hydrogen-, and nitrogen cycle with renewable electricity holds promises for the mitigation of the facing environment and energy crisis, along with the continuing prosperity of the human society. Descriptors bridge the gap between the physicochemical factors of electrocatalysts and their boosted activity and serve as guiding principles during the rational design of electrocatalysts. The optimal adsorption strength of key intermediates is potentially accessed under the tendentious guidelines proposed by indicators, such as d-band center, ΔG H , E O* , coordination number (CN), bond length, etc. Here, in this review, a comprehensive summary of the recent advances achieved regarding the descriptors during the rational design of electrocatalysts that aims for the recycling of C/H/N-containing chemicals is offered. The review is initiated by providing the necessity of the development of efficient electrocatalysts and then the physics behind the d-band center is introduced. Then a summary of the recent progress relating to the development of electrocatalysts under the guidance of descriptors is reviewed. Following that, an extended discussion regarding the experimental or theoretical characterization of the d-band center and the descriptors beyond it is provided. Finally, perspectives and challenges in this area are offered.

CO2 conversion to added value products using green processes in terms of source of energy, energy consumption, and/or management of raw materials obtained from waste materials are very attractive approaches for a modern sustainable society. In this work, such approaches are integrated, converting CO2 into ethanol by using polluted air as feeding gas. More specifically, recycled permanently polarized hydroxyapatite catalysts are prepared by applying a thermally stimulated polarization process to pork, beef, and chicken scrapped bones. The recycled bone catalysts are used to perform a series of reactions fed with polluted air and only powered with solar energy using a solar furnace. Reactions are conducted for 5 days and 1 month. Results demonstrate significant decarbonization, converting CO2 into valuable chemical products with high selectivity toward ethanol (up to 99.6%).
