🚨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 exportingΒ sunbeltΒ country (EgyptπŸ‡ͺπŸ‡¬ )."

🧡
1/7 ImageImageImage
The results show that πŸ‡ͺπŸ‡¬ 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."
2/7 Image
"The provision of both services enhances the domestic energy system performance by reducing the levelised costs of important feedstocks, #CarbonDioxideRemoval and hydrogen, as well as other domestic cost metrics and system losses."

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."
2/6 Image
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 marine research team led by Professor Yan Qingyun has proposed a method "to assess the net #CarbonSink of marine #macroalgae (Gracilaria) cultivation. Then, they computed net C sink of Gracilaria cultivation in China based on Gracilaria's annual yield in the last 10yr."
🧡 Image
Also, "the net #CarbonSink trend of #Gracilaria cultivation in the next ten years was predicted by the autoregressive integrated moving average model (ARIMA)."
2/9
Finally, researchers "explored the potential #CarbonSink increase and methane reduction related to #Gracilaria cultivation in China through a scenario analysis."

🚨NEW STUDY🚨

"#NegativeEmissionsTechnologies are needed to achieve #NetZero emissions, but their deployment will depend on regional & national circumstances, technology availability, & decarbonization strategies."

In this regard, a new study is done. Details below in a 🧡
1/7 Image
The recent paper reviews "the literature and maps the role of Process Integration (PI) in #NETs deployment."
2/7 Image
"Techniques such as mathematical programming, pinch analysis (PA), process graphs (P-graphs), are powerful methods for planning #NET systems under resource or footprint constraints."

🚨NEW STUDY🚨

Recent research analyzed "future wildfires burned areas & C emissions under #SolarGeoengineering & Shared Socioeconomic pathways (SSPs) scenarios & assessed how the different geoengineering approaches impact #fires."

Results are discussed in a 🧡 below ⬇️:

The major conclusions and implications drawn from this study are as follows:
2/13
1️⃣ "The global total #wildfire burned A is projected to rise under the unmitigated scenario (SSP5-8.5) & drop under the 2 #geoengineering scenarios (#SolarIrradianceReduction & #StratosphericSulfateAerosols) based on a comparison of the averages of 2091–2100 as to 2021–2030."
