Carbon removal company Gigablue has entered into an agreement with SkiesFifty, a firm investing in net-zero solutions, to sequester 200,000 tons of CO2 over the next four years, according to a Jan. 14 press release.
Gigablue’s technology focuses on scalable permanent carbon removal solutions leveraging the oceans, the company said.
Gigablue said it relies on a marine carbon fixation and sequestration method, which is expected to offer a lower-cost route to sequestering carbon with biogeochemistry.
The core of its carbon removal solution is a “novel” substrate consisting of a contained nutrient shell and a gravity-controlling core that acts as the optimal environment for local phytoplankton growth, Gigablue said.
“Once the phytoplankton multiply and reach a sufficient amount, the controlled sinking trigger activates, and the substrate, together with the attached carbon, sinks to the bottom of the ocean for permanent storage,” the company said.
The agreement, coupled with a growing pipeline of offtake agreements set to be announced in the coming months, puts Gigablue on a path to remove a gigaton of carbon dioxide by 2035, the company said.
"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,” said Ori Shaashua, co-founder and chief commercial officer of Gigablue.
