🚨📝NEW PAPER 📝🚨

Recent study present an analysis of “the gap between the CO2 storage required to meet net zero targets and the slow maturation of regional storage resources.”

#NetZero
#EuropeanGreenDeal
#CarbonDioxideStorage
#EnergyTransition

🧵 1/12

Researchers estimate that “European storage rates need to boost 30-100x by 2030 to meet #NetZero by 2050. 🇨🇳 & North America face a similar challenge. The slow global progress of #CarbonStorage undermines the latest IPCC, IEA & EU transition pathways to net zero by 2050.”
2/12

“These pathways imply a radically in teased demand for carbon capture and storage & #NegativeEmissionTechnologies (#NETs), contributing 500 of 700 megatonnes of #CarbonDioxideRemoval annually by 2050.”

🚨NEW STUDY🚨

Four scenarios investigated by the researchers from LUT University for #CarbonDioxideRemoval services & e-fuels/chemicals export. It is a first study to explore the impact of such services on an exporting sunbelt country (Egypt🇪🇬 )."

🧵
1/7

The results show that 🇪🇬 can technically provide 5% of the required global #CarbonDioxideRemoval capacity via Direct Air Carbon Capture & Storage (#DACCS) starting from 2035, & 10% of Europe’s demand for e-fuels & e-chemicals starting from 2025 within land use constraints."

Plants are the best option for capturing CO2

"They naturally extract CO2 from the air and use it as feed. The more CO2 plants absorb, the less CO2 remains trapped in the atmosphere."

As plants decompose, CO2
is released back to the air

"If left alone, plants are eaten by other organisms and releasing the carbon back to the carbon cycle within months."

A recent study used "an Earth system model to examine the response of #OceanAcidification to idealized atmospheric #CarbonDioxideRemoval scenarios."

Details in a 🧵below ⬇️
1/8

"In the simulations, atmospheric CO2 is assumed to increase at a rate of 1% per year to four times its pre-industrial value and then decreases to the pre-industrial level at a rate of 0.5%, 1%, 2% per year, respectively."
2/8

Results show that "the annual mean state of surface ocean #carbonate chemistry fields including [H+] conc., pH & aragonite saturation state respond quickly to removal of atmospheric CO2. Yet, the change of seasonal cycle in CaCO3 chemistry lags behind the decline in atm CO2."

A recent study "uses a lightweight integrated assessment #model SCORE to explore possible scenarios using #CarbonDioxideRemoval for limiting #GlobalWarming to 1.5 °C by 2100."

"Particularly, this exploration quantify the impacts of relying on #CDR when accounting for:
1️⃣ possible under- and overestimation of the cost, potential, and availability (feasibility) of future CDR and
2️⃣ the compound effect with uncertainty in climate sensitivity."
2/9

"All scenario results show that aggressive near-term mitigation is required for limiting warming to 1.5 °C by 2100 for all levels of climate sensitivity, but that some amount of #CDR is likely required in the future even if climate sensitivity turns out to be extremely low."

🚨NEW STUDY🚨
"Six models are used in a recent study to analyze the climatic, environmental & socio-economic consequences of #overshooting a C budget consistent with the 1.5°C temp target along the cause-effect chain from emissions & #CarbonRemovals to climate risks & impact."
🧵

"Global climatic indicators such as CO2-concentration and mean temperature closely follow the #CarbonBudget #overshoot with mid-century peaks of 50 ppmv and 0.35°C, respectively."
2/10

Findings of this study highlight that "investigating #overshoot scenarios requires temporally and spatially differentiated analysis of climate, environmental and socioeconomic systems."

🚨NEW STUDY🚨

🌊Recent study "presents the mass balances linked with #CarbonDioxideRemoval using seawater as both the source of reactants & as the reaction medium via electrolysis following the “Equatic” (formerly known as “SeaChange”) process."

🌊Details in a 🧵 below ⬇️
1/12

"The #Equatic process, broadly detailed in (pubs.acs.org/doi/full/10.10…), involves the application of an electric overpotential that splits H2O to form H+ & OH– ions, producing #acidity & #alkalinity, i.e., in addition to gaseous coproducts at the anode & cathode, respectively."
2/12

"The #alkalinity that results, i.e., via the steady electrolytic pH pump results in the rapid precipitation of CaCO3, hydrated magnesium #carbonates (e.g., nesquehonite & hydromagnesite, etc.) or Mg(OH)2 depending on the carbonate ion-activity in solution."

🚨🆕STUDY🚨
"The study explored the wide range in #CDR deployment volumes across 1.5°C compatible & high overshoot pathways by evaluating the links btw CDR & conceptually linked scenario aspects, via focus on CDR in 2050 & scenario properties related to reaching #NetZero CO2."
🧵

"#CDR volumes
were further evaluated in terms of their relative and absolute contribution to total mitigation up until reaching
net-zero CO2, showing considerable variation across scenarios with a median relative contribution of around 20%."
2/7

"The volumes of #CDR in 2050 and 2100 and the cumulative amount throughout the 21st century were most strongly correlated to the degree to which CO2 emissions are reduced as a means of reaching net-zero CO2."

🚨PAPER🚨

#DAC of CO2 from the atm. is being explored as a tech. that can contribute to the goal of reaching #NetZero CO2 emissions.

A new study led by @DonglongFu1 showed that the use of zeolitic materials are feasible for DAC when it is integrated with H2O harvesting.
🧵
1/7

"A combination of a commercially available desiccant, AQSOA-Z02A, and a mordenite-type zeolite (MOR) enables
continuous operation of a designed #DAC system comprised of two
parallel units with a regeneration temperature of 100°C," research finds.
2/7

Furthermore, "the system
using pure #zeolite alone requires regeneration at temperatures between 200°C and 300°C."
