Brineworks is an Amsterdam-based climate-tech company founded in 2023 by Gudfinnur Sveinsson and electrochemist Dr. Joseph Perryman. Its patented electrolyser captures CO₂ directly from the air while simultaneously generating substantial volumes of hydrogen, creating a cost-effective feedstock pair for sustainable aviation fuel and e-methanol. The system is designed to run intermittently, matching the variable output of wind and solar power without performance loss, which lowers operating costs and aligns with the falling price of renewable energy. This flexibility, combined with inexpensive materials, targets the current bottleneck in scaling e-fuels for hard-to-abate sectors like aviation and shipping. Aviation accounts for roughly 2.5 % and shipping over 3 % of global CO₂ emissions, providing a large market need for Brineworks’ solution. The company plans to scale its technology to pilot level with the new capital and aims for commercial readiness by late 2026. No revenue or user metrics have been disclosed.
