SeaO2's direct ocean capture (DOC) assets and intellectual property will survive the company's bankruptcy through a split acquisition, with CarbonBlue taking over the physical assets and CTRL-S acquiring the IP, co-founder Ruben Brands announced.

The deal closes out a bankruptcy filed just months ago by the Netherlands-based startup, which had raised over $2 million to develop an electrochemical process that uses renewable electricity to extract CO2 directly from seawater.

Who gets what from the SeaO2 estate?

The split works along two lines:

• CarbonBlue, led by Iddo Tsur, takes over SeaO2's assets, including the hardware behind its electrochemical capture system.
• CTRL-S (Climate Tech Rescue, License & Scale), led by Jason Hochman, acquires the intellectual property developed by SeaO2's team.

Both pieces were the core of what SeaO2 said it wanted to preserve when it declared bankruptcy. At the time, the company stated it was "actively exploring a restart," arguing that its technology, patents, a pilot deployment and accumulated know-how held high value in the ocean-based carbon dioxide removal (CDR) field.

That restart now takes the form of a handoff rather than a rescue. Brands, writing in a publication announcing the transfer, thanked the two acquiring companies directly.

"A big thank you to Iddo Tsur at CarbonBlue and Jason Hochman at CTRL-S and their teams for their trust and for the constructive way we got here," Brands wrote. "The technology, know-how and ambition we built over the past years now get the chance to move forward, and I'm confident that in their hands SeaO2's work will create even more impact."

Why did SeaO2 fail?

Founded in 2021, SeaO2 spent roughly five years building a DOC system designed to be affordable and scalable. The approach attracted over $2 million in funding, including $1.9 million for a water-to-e-SAF project, but the capital did not arrive fast enough to get operations running.

Despite public calls for further support, the company could not close the funding gap within the timeframe it needed. Brands attributed the bankruptcy to capital that moved too slowly, not to a failure of the technology itself.

The pattern is not unique to SeaO2. The funding gap that sank the company stands as one of the major obstacles facing CDR developers across the full spectrum of pathways and approaches — from direct air capture to ocean-based electrochemical methods.

What happens to the technology now?

For the DOC field, the transfer keeps a working electrochemical process and its associated patents in play rather than leaving them dormant in a bankruptcy estate. CTRL-S's name — Climate Tech Rescue, License & Scale — signals its model: acquiring distressed climate IP and licensing or scaling it under new ownership. CarbonBlue, which is developing its own water-based carbon removal approach, gains hardware assets that complement the IP transfer.

The deal structure means SeaO2's technology will continue under two separate operators, with each company integrating a different piece of the estate. Whether the pilot deployment and know-how translate into operating capacity under new ownership will depend on how quickly the acquirers can fund and deploy what they inherited.

Brands himself is moving on. He says he is starting a new chapter and is looking for experienced founders, serial entrepreneurs, and technology and research experts to collaborate on new opportunities.

The milestone to watch now is the first commercial deployment of SeaO2-derived technology under the CarbonBlue and CTRL-S banners — the test of whether a bankruptcy transfer can preserve a CDR pathway that capital markets declined to fund the first time around.
