Planetary develops technology that accelerates the ocean’s ability to remove atmospheric carbon dioxide by safely boosting the planet’s largest natural carbon removal mechanism, the geologic carbon cycle. The company partners with leading scientific institutions, regulators, and coastal communities to ensure its methods meet rigorous environmental and social standards. Its approach centers on deploying alkalinity-enhancing interventions in marine environments to increase CO₂ uptake, though detailed technical specifications were not provided in the article. Current pilot projects are generating data on effectiveness and ecological impact, positioning Planetary to refine and scale its solution. The newly secured funding will be used to deepen research and development, expand pilot installations, and grow the firm’s operational footprint. Financially, Planetary has raised a $7.5 million seed round; no additional revenue, user, or prior funding figures were disclosed.
