Take a step-by-step walkthrough of how their solution works in a 🧵 below ⬇️

1️⃣ "@ebbcarbon with aquaculture farms, desalination plants, ocean research labs, and other industrial sites that process seawater."
2/10
2️⃣ "Ebb intercepts existing salt water flows at the facility and processes the water before it returns to the ocean."
3/10
3️⃣ "Using low carbon electricity, Ebb run the salt water through a stack of ion-selective membranes that separate it into acidic and alkaline solutions."
4/10
4️⃣ "Ebb measure and monitor the pH level and volume of the alkalinity we produce in real time. This enables us to safely return it at levels within the ocean's natural pH variance."
5/10
5️⃣ "Ebb return the alkaline solution to the sea, where it immediately lowers the acidity of the sea water locally."
6/10
6️⃣ "Over weeks to months, the alkaline solution reacts with dissolved CO2 in seawater to create bicarbonate (HCO3), a stable form of carbon storage for 10,000+ years."
7/10
7️⃣ "With more CO2 locked away as bicarbonate, the ocean will naturally equilibrate and sequester more CO2 from the air. Ebb measures the CO2 removed from the air using sensors in the water and ocean and carbonate chemistry models."
8/10
8️⃣ "By partnering with the ocean, Ebb Carbon has the potential to be one of the most energy efficient and cost effective ways to reverse the impacts of climate change both locally and globally."

A new study from Colorado State University's Dept. of Soil & Crop Sciences & the Graduate Degree Program in Ecology found “that #regenerative practices—including integrating crop & livestock systems—were successful as long-term #CarbonStorage solutions.”
🧵 1/7
Researchers conducted a “global systematic meta-analysis of the effects of #regenerative management practices on Soil Organic Carbon (#SOC), Particulate Organic Carbon (#POC) & Mineral-Associated Organic Carbon (#MAOC) in cropland.”
2/
They found that:
1️⃣ “no-till (NT) and cropping system intensification increase #SOC (11.3% and 12.4%, respectively), #MAOC (8.5% and 7.1%, respectively), and #POC (19.7% and 33.3%, respectively) in topsoil (0 to 20 cm), but not in subsoil (>20 cm).” 3/
The study, published in @Nature, “is the first of its kind to show the sustained benefits of tree diversity on a large spatial scale, in terms of #storing#carbon and nitrogen in the soil. It reinforces the importance of biodiversity conservation in forests.”
2/8
The researchers analyzed “Canada's National Forest Inventory database & used statistical modeling to provide new evidence of a link between greater tree diversity & higher soil C & N accumulation in natural forest ecosystems over decadal time scales.”

1️⃣ 💵 @Microsoft & @Orsted ink “one of the world's largest” carbon removal deals as Microsoft buys 2.76 million tonnes of #CarbonRemoval from Ørsted using #BECCS. To be delivered over 11 years.
2️⃣ 💸Buyers working through Frontier have binding contracts for $53 million with the startup @CharmIndustrial to remove 112,000 tons of CO2 between 2024 & 2030.
*“Charm turns waste biomass into bio-oil & stores it underground for +1000 years.”
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."
