"#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
The recent paper reviews "the literature and maps the role of Process Integration (PI) in #NETs deployment." 2/7
"Techniques such as mathematical programming, pinch analysis (PA), process graphs (P-graphs), are powerful methods for planning #NET systems under resource or footprint constraints." 3/7
"Other methods such as multi-criteria decision analysis (MCDA), marginal abatement cost curves, causality maps, and machine learning (ML) are also discussed," in this study. 4/7
"Current literature focuses mainly on bioenergy with carbon capture and storage (#BECCS) and afforestation/reforestation (#AR), but other #NETs need to be integrated into future models for large-scale #decarbonization," study found. 5/7

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." 2/7
"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." 3/7
🚨🌊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."
🧵
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."
3/9
Recent research analyzed "future wildfires burned areas & C emissions under #SolarGeoengineering & Shared Socioeconomic pathways (SSPs) scenarios & assessed how the different geoengineering approaches impact #fires."
