A startup creating expertise to take planet-heating carbon dioxide out of the ambiance simply signed a cope with a state-owned water utility in South Korea to construct a pilot challenge that mixes the brand new local weather tech with seawater desalination.
The primary-of-its form collaboration is meant to wash up a number of the air pollution from an enormous hub for petrochemical manufacturing close by, on high of supplying contemporary water to heavy industries within the space.
Relying on the way you take a look at it, partnerships like this may very well be an modern approach to reduce the environmental harm from very soiled enterprise, or a approach to maintain fossil fuels flowing when the world wants cleaner alternate options. Both approach, it’s an instance of how the fossil gasoline trade is cozying up with rising applied sciences, like direct air seize (DAC), that are imagined to struggle local weather change but in addition have skeptics frightened about whether or not it would grow to be a crutch for giant polluters.

“We really type of agree with the critique that in case you do a DAC challenge, and that makes you extra water insecure, or extra local weather weak, or if that perpetuates fossil fuels on the grid, that’s an issue,” says Luke Shors, president of the California and New Zealand-based local weather tech startup Capture6 that inked the deal. “We really assume these initiatives can accomplish a number of local weather objectives, and that’s why we must always pursue them.”
Shors’ firm signed a memorandum of understanding (MOU) this week with South Korean water utility Okay-water and wastewater therapy firm BKT. Collectively they’ll develop what they are saying is the world’s first absolutely built-in facility for carbon elimination and water administration utilizing seawater desalination.
Capture6 plans to construct Undertaking Octopus, a carbon elimination plant that it hopes will ultimately take away a whole lot of 1000’s of tons of carbon dioxide from the ambiance every year — a feat {that a} rising variety of startups world wide are attempting to attain.
What’s distinctive about Undertaking Octopus is the way it’s anticipated to work in tandem with a plant that turns seawater into contemporary water. One draw back with desalination vegetation is that they produce salty brine that may be dangerous when launched into the encircling atmosphere. Capture6 as an alternative makes use of that wastewater in its carbon elimination course of, extracting salt that it then makes use of as a feedstock for a liquid sorbent that reacts with CO2 within the air.
The answer traps CO2 which, after mixing with calcium, produces a limestone or chalk-like mineral that retains the greenhouse fuel from escaping again into the ambiance. Contemporary water is one other byproduct of the method.
This no silver bullet for local weather change or drought, and these applied sciences include their very own prices. DAC and desalination vegetation each use quite a lot of power. And for the reason that pilot facility will likely be plugged into the grid, which means it would nonetheless be powered largely by fossil fuels and producing the identical greenhouse fuel emissions Undertaking Octopus is supposed to wash up.
Furthermore, the ability is actually being constructed to service the Daesan Industrial Advanced that produces 40 p.c of South Korea’s petrochemicals derived from oil and fuel. “[The industrial complex] will exist, proper? It doesn’t matter what we do. So I believe that’s why it’s crucial for us to be on the identical time sensible,” says Leo Park, vp of strategic improvement at Capture6. “I assume it’s essential for us to scale back their carbon footprint any approach we are able to.”
If it’s in the end capable of develop right into a commercial-scale facility, Undertaking Octopus may seize as much as 500,000 metric tons of CO2 yearly as soon as absolutely accomplished. The pilot facility is meant to attract down simply 500 metric tons of atmospheric carbon dioxide a 12 months, and the MOU additionally consists of plans to filter one other 500 metric tons of CO2 from smokestacks earlier than it’s launched into the ambiance.
Altogether, that’s only a fraction of the 17 million metric tons of carbon dioxide Daesan pumps out every year. And to succeed in world objectives of stopping local weather change set below the Paris Settlement, polluters must slash their CO2 emissions in half this decade. The plan at Undertaking Octopus is to start out development on the $2-3 million pilot this 12 months, however breaking floor on a doubtlessly $100-200 million industrial facility won’t occur till late 2026 on the earliest.
