-Inside the tiny corner of Spain that lies in the middle of North Africa [[https://kraken12s.at/|kraken официальный сайт]]
+UK project trials carbon capture at sea to help tackle climate change [[https://kra34c.cc/|кракен]]
+The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently.
-In ancient Greek and Roman legend, the Pillars of Hercules –marking the edge of the known world – were mighty columns that once stood either side of the strait where the Mediterranean Sea meets the Atlantic.
+The practice is not free of controversy, with some arguing that carbon capture is expensive, unproven and can serve as a distraction from actually reducing carbon emissions. But it is a fast-growing reality: there are at least 628 carbon capture and storage projects in the pipeline around the world, with a 60% year-on-year increase, according to the latest report from the Global CCS (Carbon Capture and Storage) Institute. The market size was just over $3.5 billion in 2024, but is projected to grow to $14.5 billion by 2032, according to Fortune Business Insights.
-One was on the Rock of Gibraltar, a pocket of British territory next to mainland Spain, and the other was Ceuta, a prominent outcrop on the North African coastline.
+Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions.
-Today, Ceuta is a Spanish exclave, a piece of a country entirely surrounded by another, in this case Morocco. And while it may only be 18 miles from the Spanish mainland, this tiny pocket of Europe in Africa is one of the most unusual places on either continent.
+In the UK, where the government in 2023 announced up to £20 billion ($26.7 billion) in funding to support carbon capture, one such project has taken shape near the English Channel. Called SeaCURE, it aims to find out if sea carbon capture actually works, and if it can be competitive with its air counterpart.
-Surrounded on three sides by water, Ceuta is protected by high medieval walls, stone citadels and barbed wire that all hint at its tumultuous history.
+“The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team.
-With an area of just seven square miles and a population of around 85,000 people, this peninsula jutting abruptly into the Mediterranean Sea has been in the possession of Spain since 1580.
+“But it also means it’s very straightforward to take that carbon out of the water.”
-But the exclave is more than just a colonial hangover; with architecture, culture and cuisine blending influences from both sides of the Strait of Gibraltar, this could be Spain’s most multicultural city.
+Pilot plant
+SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute and remove an estimated 100 tons of CO2 per year.
-“Ceuta was given the title of the most loyal city in Spain,” Mila Bernal, a local tourism office representative, told CNN Travel. “Because the citizens decided they wanted to be Spanish, not Portuguese.”
+“We wanted to test the technology in the real environment with real sea water, to identify what problems you hit,” says Halloran, adding that working at a large public aquarium helps because it already has infrastructure to extract seawater and then discharge it back into the ocean.
+The carbon that is naturally dissolved in the seawater can be easily converted to CO2 by slightly increasing the acidity of the water. To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says.
