Cool Company Raises · $53.5M
Captura raises a $53.5M round
The ocean is an immensely powerful force of nature, and our greatest ally to reverse the tides on climate change. By studying the planet’s natural cycles, Captura designed a solution that removes CO2 from the ocean and harnesses its ability to heal the climate—a process known as Direct Ocean Capture. Developed and proven in Caltech’s laboratories, our unique Direct Ocean Capture technology runs with just two ingredients: seawater and renewable electricity. It extracts CO2 directly from seawater to be permanently stored or reused. This amplifies the natural equilibrium between the ocean and atmosphere, drawing carbon out of the air and into the ocean to rebalance. Captura’s approach requires no rare-Earth minerals, adds nothing to the ocean, and leaves no chemicals behind. It’s a low-cost, large-scale carbon removal solution that is environmentally sound.
