"#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

🚨 In a NEW study published today, researchers presented an analysis of the atmospheric sulfur budget using nine state-of-the-art global circulation models with interactive aerosol modules & sulfur chemistry.
In particular, "researchers showcase the burdens of the main sulfur species represented in these models (OCS, sulfate aerosols, and SO2), as well as their latitudinal and vertical distribution and seasonal variability. Emission and deposition fluxes were also discussed."
2/12
FINDINGS:
"Sulfate aerosol, carbonyl sulfide & SO2 behave very differently in the atm, providing insight into the modeled processes. OCS is almost chemically inert in troposphere & is primarily influenced by transport mechanisms but undergoes photolysis in stratosphere."

#CarbonDioxideRemoval
#CDR
🧵0/17
@SthlmExergi signed a contract with @Microsoft covering 3.33M tonnes of permanent CDRs over 10 years from BECCS plant at Värtan, Stockholm. "The agreement represents the world's largest permanent removals deal to date."
The Midwest Nuclear DAC Hub (MINDAC) – one of the 19 #DirectAirCapture projects announced for award negotiations by @ENERGY, received the $4 million investment by the DOE.
🚨NEW study explored a system that combines enhanced olivine weathering (EOW) with increased C fixation by diatoms.
EOW can boost ocean's ability to sequester DIC while stimulating diatom growth, which in turn would fix more C & reinforce biological C pump processes. #CDR
🧵1/8
In this study, researchers investigated the short-term synergistic CO2 removal effects of an olivine–diatom coculture system & found that:
2/8
1️⃣ "Over a 6-day incubation period, the olivine dissolution was 92%–144% higher in the olivine–diatom groups compared with the olivine-only groups."
🚨🚜 @Veolia, the UK’s leading resource management firm, has partnered with UK biotechnology startup, @fabricnano, to apply enzymes to rocks to trial faster, permanent #CarbonRemoval directly from the atmosphere.
#EnhancedRockWeathering
“With this world-first trial pairing biology with geology to accelerate rock weathering for carbon sequestration, @Veolia aims to reduce the energy consumption, emissions and timescales for carbon removal by utilizing enzymes to accelerate the natural weathering process.”
2/9
“@fabricnano’s patented technology immobilizes the Carbonic Anhydrase enzyme directly onto large particle basalt, accelerating carbon sequestration timelines from decades to just a couple of years.”
