"The Amsterdam-based startup claims it has rapidly developed a low-cost, patented technology over the past two years that uses seawater to pull CO2 from seawater, which creates significant amounts of hydrogen in the process. The system, known as electrolysis, produces hydrogen and CO2 that can be stored and sold as sustainable aviation fuels (SAF) and e-methanol for shipping. CEO Gudfinnur Sveinsson told Fortune in an exclusive interview that the new funding will be used to scale the system to pilot level,"
""What this (funding) is allowing us to do is really to take our technology to the next stage," Sveinsson said. "Getting to those very low costs in direct air capture will be key to both extract historical emissions out of the atmosphere and store them permanently, but also to scale up these low-cost energy mediums like e-fuels for shipping and aviation.""
"Sveinsson said Brineworks' technology is designed for intermittent operation, allowing it only to run on the "cheapest electricity sources available": solar and wind. This helps drive down costs and differentiates his business model from competitors, he said. Brineworks has partners in North America, Europe, and Asia, and is looking to map out projects in Northern Africa and the Middle East "to start demonstrating the technology at larger scales, showcasing that it works in different climates, which is very important for the scalability,""
Brineworks raised $5.5 million in seed funding to scale a seawater electrolysis system that extracts CO2 and produces hydrogen for low-carbon fuels. The patented process pulls CO2 from seawater while generating hydrogen that can be stored and sold as sustainable aviation fuel (SAF) and e‑methanol for shipping. The company plans to use the funding to reach pilot scale and target a commercially ready product by late next year, aiming for market entry by the end of 2026. The system is designed to operate intermittently on cheap solar and wind power to minimize costs. Brineworks has partners across North America, Europe, and Asia, seeks demonstration projects in Northern Africa and the Middle East, and recently received a $1.8 million grant from the European Innovation Council Accelerator. The company was founded in 2023 by Gudfinnur Sveinsson.
