Exclusive: the climate startup of Brineworks technology increases $ 5.5 million

The Amsterdam -based startup says that it has quickly developed a low -cost patented technology in the past two years that has used sea water to draw seawater from CO2, which creates significant quantities of hydrogen in the process. The system, known as electrolysis, produces hydrogen and CO2 which can be stored and sold as sustainable aviation fuels (SAF) and an e-methanol for shipping. CEO GUDFINNUR SVEINSSON said Fortune In an exclusive interview, the new financing will be used to evolve the system at the pilot level, targeting a product ready for trade by the end of next year.

“What this (financing) allows us to do is really to pass our technology to the next step,” said Sveinsson. “The damage to these very low costs in direct air capture will be the key to extracting historical emissions from the atmosphere and storing them permanently, but also to increase these low-cost energy supports such as E-Fuel for shipping and aviation.”

Sveinson has said that Brineworks technology is designed for intermittent operation, which only allows it to operate on the cheapest available electricity sources “: solar and wind. This helps reduce costs and differentiate its business model from competitors, he said.

BrineWorks has partners in North America, Europe and Asia, and seeks to trace projects in North Africa and the Middle East “to start demonstrating technology on a larger scale, presenting that it works in different climates, which is very important for scalability,” said SveinSson.

The startup recently received a funding subsidy of $ 1.8 million from the Accelerator Program of the European Innovation Council, which invests in startups and SMEs.

The company was founded in 2023 by Sveinson, a graduate of the University of Columbia with training in climate policy and innovation, and Joseph Perryman, an electrochemist who completed his postdoctoral research at the University of Stanford. Perryman is now working as CTO de Brineworks.

The seed financing tour was led by Seax Ventures, a world capital-capital company based in San Francisco, which has just launched a climate-oriented fund.

“I think they have revolutionary technologies,” said Kid Parkhariyanon, founder and director of director at Seax Ventures, explained Fortune.

Seax Ventures often invests in businesses in the start-up phase, including Bitkub, one of the largest crypto scholarships in Southeast Asia, and an energy type, a merger-energy company that was estimated between $ 214 and $ 321 million following the main financing towers in 2025.

Global Investments for Renewable Energy Development had a record for the first half of 2025, reaching $ 386 billion and up 10% compared to the previous year, according to the monitoring of Bloombergnef renewable energies. This growth has been largely stimulated by the world’s offshore wind and small solar energy on a small scale. The international energy investment report of the International Energy Agency estimates that capital flows to the energy sector should reach $ 3.3 billions this year, investments in renewable energies doubling that of investments towards fossil fuels. Low emission fuel will represent $ 40 billion, the report said.

As the investment of renewable energies increases, companies seek to differentiate themselves from competition.

“We have imagined the electrolyzer of the future – and now he is here,” PERRYMAN said in a company statement.
