“If we are able to unlock growth in the open ocean, which we think is possible, it has the potential to be very large,” Odley told the MIT Technology Review last year.

But sources say initial efforts to move beyond the coast have not produced much kelp.

The fact that Tide’s remote imaging system is running shows that the teenage sugar kelp seed on the lines is growing in the ocean, Odley said in an email that, to the knowledge of the company, this had not been achieved before.

He acknowledged that “yields and consistency are not yet in line with what is needed to remove large-scale carbon.” But he said the company has not yet met its expectations, and some initial efforts focused primarily on technical testing of the company’s systems and deployment methods.

He and Justin Reese, a senior scientific adviser at Running Tide, added that scientists already know that kelp grows in the open sea, because there are variations. They said the company would continue testing on a small pilot scale until it had identified the best species, locations and conditions.

“No one said this would be easy,” Odlin says, noting that they are working with complex biological systems and a wide variety of macroalgi species. “Some will work really well; Some are not; Some will have huge variations… it’s part of systems optimization that takes years. ”

“It may take 30, 40 deployments to get this traction and get it right,” he added, adding that the company is still “a long way” away from “significant deployment”.

Departure

Staff has been out in recent months, according to LinkedIn, including Margox Philippi, director of oceanography; Raj Saha, Senior Data Scientist; Olivia Alcabes, data research scientist; Jean Bertrand Contina, agronomist lead for macroalgi production; And Maxwell Calloway, Senior Calp Biologist. They either did not respond to inquiries or declined to comment for this part.

According to the career networking site, most of the researchers left the company after less than a year and many only after six months.
