Gigablue, a company specializing in carbon dioxide removal (CDR) solutions, has announced a substantial new mCDR agreement with aviation sustainability company SkiesFifty.
Under the four-year agreement, Gigablue will remove the striking amount of 200,000 tons of CO2, a deal that represents the largest marine carbon removal to date.
This partnership builds on a successful collaboration between the two companies back in July 2024, and it falls in line with SkiesFifty’s goal of investing in scalable technologies that would contribute towards a net-zero future of the aviation industry.
Gigablue has developed an original biogeochemistry mechanism powered by marine carbon fixation and sequestration (MCFS).
In its essence, Gigablue’s carbon removal technology represents a substrate made up of a nutrient shell and a core that has a gravity-controlling capacity, providing the optimal environment in which local phytoplankton can grow and flourish.
With the help of the substrate, the phytoplankton multiply, and once they reach a sufficient amount, the controlled sinking trigger activates, prompting the substrate along with the attached carbon to sink to the ocean bottom for permanent storage.
This system, naturally powered by sunlight, water, and gravity, signals Gigablue’s promising potential for storing CO2 at a gigaton scale in a safe and cost-effective manner.
Ori Shaashua, co-founder and chief commercial officer at Gigablue, shared that this agreement validates the scalability and effectiveness of their technology.

He stated, “We are harnessing the basic building blocks of life on Earth—water and sunlight—to create a financially sustainable carbon removal solution. This will be the largest marine carbon dioxide removal offtake agreement to date and proves our technology’s viability in the market.”
The agreement with SkiesFifty is one of many offtake agreements that Gigablue is set to announce in the following months.
According to the company, once all partnerships are operational, Gigablue will be well on its way to achieving gigaton carbon removal levels by 2035.
