The development of carbon capture technology has been slow, partly due to high costs. However, the American startup Captura is developing ocean carbon capture technology that promises to halve these costs.
The company has already attracted investments from notable enterprises such as Japan Airlines and Saudi Aramco, and plans to fully launch its operations by 2026.
Innovative floating carbon capture factories
Captura's design involves setting up floating factories at sea. These factories use electrodialysis to convert part of the seawater into acid, which is then mixed with seawater to carbonate it. The carbonated water is then passed through a filtration membrane to separate out the carbon dioxide.
