The world's first ocean carbon removal pilot facility has been relaunched by a Hawaii-based company ...

Heimdal, a Hawaii-based company, is developing a new "ocean-assisted" carbon removal technique that can permanently store CO2 as well as alleviating ocean acidification, according to a FastComapny report.

Saltwater is then pumped into a conveyor that is powered by electricity to keep the molecules in the water and reduce the acidity.

The acid is removed in the form of hydrochloric acid, which can be stored and sold separately. The process also produces hydrogen and oxygen as byproducts, which can also be stored. Meanwhile, the water is returned to the ocean, where it will help to capture CO2.

"When the excess acidity is removed from the ocean, it shifts how CO2 reintroduces back to how it was before the Industrial Revolution," Erik Millar, the co-CEO of Heimdal, toldFastCompanyin in an interview. "This shifts it away from being carbonic acid, which causes ocean acidification, and toward bicarbonate and carbonate. These are stable forms of mineralized carbon dioxide that make their way down to the ocean floor, where they are stored for more

Eliminating CO2 from the atmosphere is an oceanic task.

The ocean absorbs a huge amount of CO2, but the more CO2 it carries, the slower the process of transitioning towards the ocean''s saturated oceans, where the ocean has produced one third of the excess CO2 that humans have released into the atmosphere.

Researchers from the University of California Los Angeles (UCLA) announced their intention to establish a new business called Seachange, which uses CO2 in ocean water to be a material similar to seashells, allowing it to be permanently stored. Similarly, the process was designed to enable the ocean to absorb more CO2 from the atmosphere.

Heimdal has launched a solar-powered pilot facility utilizing the infrastructure of an existing desalination facility that already has the capacity to pump large amounts of seawater. The company claims that its technology has currently capacity to capture CO2 at a cost of $475 per ton, and the pilot plant is capable of producing 36 tons of CO2 per year. In addition, Heimdal hopes to build the next facility in Portugal or Dubai.

Carbon removal technology is rapidly developing, and economics may be a major concern. The UCLA researchers from Seachange said they would employ 1,800 employees, called SouthSouth, to remove 10 billion metric tons of carbon dioxide each year, resulting in a world of billions of dollars. According to a new IPCC report, the world will have to remove roughly six billion tons of CO2 per year by 2050 to avoid the greatest effects of climate change.
