Industrial Direct Ocean Capture (DOC) based on electrolysis

Based on our research into ocean-based carbon removal companies, this article discusses industrial Direct Ocean Capture (DOC) technologies based on electrolysis. For example, Planetary Technologies develops an electrolyzer to produce naturally abundant alkaline minerals like Mg(OH)₂ and adds Mg(OH)₂ solution to seawater to enhance local alkalinity for CO₂ sequestering. Equatic develops an electrolytic flow reactor for in-situ CO₂ removal from seawater by precipitating CaCO₃ and MgCO₃. In addition to CO₂ removal, these electrolysis-based DOC technologies can produce valuable byproducts of hydrogen.
