"Using seawater & low-carbon electricity, @ebbcarbon can remove gigatons of CO2 permanently at competitive costs."

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 Image
2️⃣ "Ebb intercepts existing salt water flows at the facility and processes the water before it returns to the ocean."
3/10 Image
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 Image
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 Image
5️⃣ "Ebb return the alkaline solution to the sea, where it immediately lowers the acidity of the sea water locally."
6/10 Image
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 Image
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 Image
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 recent field study conducted over the Great Barrier Reef has provided key insights regarding sea spray aerosols (SSA).

For the first time, it shows that SSA can reach the cloud base height, advancing Marine Cloud Brightening (#MCB) research.

DETAILS🧵1/8 Image
2/ MCB is a proposed climate intervention that aims to reflect more sunlight by enhancing marine clouds.

The concept relies on artificially generated sea spray aerosols (SSA) at the ocean surface and their transport in sufficient quantities to low-level maritime clouds.
3/ A portion of the SSA that reaches cloud height can act as additional cloud condensation nuclei and modify cloud microphysical properties, potentially reducing the amount of solar radiation reaching the sea surface.

🚨A new 3-year study found that by combining crushed rock + compost + biochar could remove 51.7 million tons of CO₂e/year—just by treating 8% of California’s rangelands.
#ERW #CDR #biochar

Here’s the details:🧵1/9 Image
2/ Researchers spread finely crushed metabasaltic rocks across test plots in Browns Valley, California, in each of 3yrs.

Along with the crushed rock, some of the applications included compost or a combination of compost & biochar (burned pine & fir left over from local logging). Image
3/ Other plots were treated with only compost, and a group of control plots received no treatment.

Throughout the year, the team monitored each plot for levels of soil organic and inorganic carbon, pore water dissolved carbon, aboveground biomass, and greenhouse gas emissions.
