“…The regeneration energy costs for their sorbent reach as low as 1.29 MJ kg À1 CO2 . 8 This represents a 45% energy cost reduction compared with commercial amine-based sorbents and is lower than any solid porous sorbents reported in literature across a wide temperature range.…”

“…detrimental oxygen evolution, as illustrated in Figure 2. 8 In practice, metal NPs coat the Li 2 O/Li 2 O 2 particles, providing stability. However, uncertainties remain as to how the solid catalyst drives conversion between Li 2 O and Li 2 O 2 within the bulk of the lithium oxide particle.…”

“…Nevertheless, empirical results clearly demonstrate that a catalyst is a prerequisite for this reaction, and in its absence the cell undergoes detrimental polarization. 8 Understanding this is critical for further development of this technology, most notably in eliminating the considerable voltage polarization during discharge and to minimize the inactive catalyst loading within the composite architecture.…”

“…Metal organic frameworks resemble a sponge, filled with magnetic nanoparticles that adsorb carbon dioxide gas. Otherwise known as magnetic induction swing adsorption (MISA), the advantage of the process is that it requires one-third of the energy input (used mainly to regenerate the capture media) compared to any other reported CO2 capture method (Sadiq et al, 2020).…”

We evaluate suggestions to harness the ability of calcifying organisms (molluscs, crustacea, corals and coccolithophore algae) to remove permanently CO2 from the atmosphere into solid (crystalline) CaCO3 for atmosphere remediation. Here, we compare this blue carbon with artificial/industrial Carbon dioxide Capture & Storage (CCS) solutions. An industrial CCS facility delivers, at some cost, captured CO2, nothing more. But aquaculture enterprises cultivating shell to capture and store atmospheric CO2 also produce nutritious food and perform many ecosystem services like water filtration, biodeposition, denitrification, reef building, enhanced biodiversity, shoreline stabilisation and wave management. We estimate that a mussel farm sequesters three times as much carbon as terrestrial ecosystems retain. Blue carbon farming does not need irrigation or fertiliser, nor conflict with the use of scarce agricultural land. Blue carbon farming can be combined with restoration and conservation of overfished fisheries and usually involves so little intervention that there is no inevitable conflict with other activities. We calculate that this paradigm shift (from ‘shellfish as food’ to ‘shellfish for carbon sequestration’) makes bivalve mollusc farming and microalgal farming enterprises, viable, profitable, and sustainable, alternatives to all CCUS industrial technologies and terrestrial biotechnologies in use today.

“…Many adsorbents controlled parameters such as cost and efficiency are directly related to the regeneration process. For example; MOF s ¢ half-life, quality, cost, and efficient adsorption capability necessitate a low regeneration energy [21,22]. Recently, a calcium-based metal-organic (named Ca(squarate)) framework shows interesting high stability and high adsorption selectivities.…”

Ab-initio Molecular Dynamic (MD) and static Density Functional Theory (DFT) are used to study the structural and bonding properties of small hydrocarbon adsorbates inside Ca(squarate)-Metal Organic Framework (MOF). Car-Parrinello Molecular Dynamics (CPMD) simulations of a single-adsorbate-MOF structure are used to obtain the adsorbate most preferred site of adsorption. This site is used for further structural and bonding analyses using static DFT. Unlike many other MOFs; we found that the Ca(squarate)-MOF physisorbs and weakly binds small adsorbate molecules such as C2H2, C2H4, C2H6, and C3H8 with no observed charge transfer and minimal hybridization with the MOF orbitals. No Covalent bonding is seen and no considerable distortion of the nearby lattice is observed at the site of adsorption. The calculated binding energies decreases as the H content in the adsorbate molecule increases and found to be -18.71 kJ/mol, -18.14 kJ/mol, -15.75 kJ/mol, and - 4.47 kJ/mol for C2H2, C2H4, C2H6, and C3H8 molecules respectively. Density of State (DOS) and a Crystal Orbital Overlap Population (COOP) analyses show that the interactions between C and H atoms in the molecule and C and O atoms in the MOF have antibonding characteristics near the Fermi level. These antibonding states tend to destabilize the overall electronic structure of the combined adsorbate/MOF system and hence decrease the binding energies of these adsorbates inside the MOF.
