"#Geoengineering—a mechanism to mitigate sea-level rise—has garnered scientific interest in line with the present state of #ClimateChange. This newly published study investigates traditional+modern SG tech through a systematic literature review."
🧵1/6 Image
The results suggest that "conventional and pioneering #geoengineering techniques can decrease sea-level rise, and those optimal results would be achieved through the cooperation of methods." 
2/6 ImageImageImage
"Ultimately, findings from this review informed five strategies: 🔸tactical application of conventional #geoengineering; 🔸optimisation through technique alignment;
🔸adaptation to receding coastlines;"

🔸"a global platform for project collaboration;
🔸progression of research capabilities

These strategies, in turn, informed a procedural guideline for policymakers who seek to mitigate sea-level rise."

🚨NEW REVIEW PAPER🚨

"This review provides an extensive evaluation of recent advances in multiscale models used for the theoretical physical descriptions of #DirectAirCapture."

🧵
1/8 Image
"Reviewed (CO2 mass) transfer works span from the ab initio density functional theory calculation relationships to mesoscale Monte Carlo, molecular dynamics simulations & micro-kinetics, adsorption/desorption, & most commonly-investigated specific macroscale concept."
#DAC
2/8 Image
The modelled #DAC processes properties reported in the literature have been compared by the authors of this review paper, which allowed them "to identify the most effective sorbents."

🚨NEW PAPER🚨

"A comprehensive #bioenergy accounting model with a multi-dimensional analysis was
developed in a new study based in #China by combining spatial, life-cycle, and multi-path analyses."

Summary in a 🧵 below ⬇️
1/6 Image
Accordingly, "the #bioenergy production potential and #GHG emission reduction for each distinct type of #biomass feedstock through different conversion pathways were estimated in the study."
2/6 Image
"The sum of all available organic waste (21.55EJ/yr) & energy plants on marginal land (11.77EJ/yr) in China produced 23.30EJ of #bioenergy & reduced 2535.32Mt CO2-eq emissions, accounting for 19.48% & 25.61% of China’s T energy production & C emissions in 2020, respectively."

🚨NEW PAPER🚨
"A promising solution to nullify the net embodied #GHG emissions of civil infrastructure is the use of C-negative materials for concrete manufacturing. C-neutral coal ash & agriculture/forestry by-products, like #biochar, exhibit a high CO2 uptake potential."
🧵
1/8 Image
📝 A lately published paper aimed "to explore the viability of using #biochar as a #CarbonSink and to develop carbon-neutral #concrete with improved performance."
2/8
📉 Experimental findings suggest that "the optimal amount of biochar (1%) slightly improves hydration and mechanical properties, but the combination with mineral additives significantly enhances the performance."

🚨PAPER🚨

The newly published article focuses on the physical & chemical aspects of #CO2 #storage via liquid & solid chemical carriers & sorbents & gives an overview of the energetics around their use & options for their future development.
#CarbonRemoval
#CarbonStorage
🧵
1/7 ImageImage
Research pointed that "exciting opportunities for coupling #capture and medium to high maturity multi-year #storage technologies could support #CarbonRemoval in the coming decades."
2/7 Image
Highlights of the analysis are:
🔸"The remarkable #storage capacity of oxalic acid & formic acid (CO2-density of 1857 kg m−3 & 1152 kg m−3, compared with condensed liquid CO2 at 993–1096 kg m−3, respectively)."
