Lillianah is scaling ocean CO2 removal with their integrated phytoplankton cultivation, release, and MRV stack. By working in marine dead zones they leverage huge amounts of nutrient runoff to enable their diatoms to grow en masse, preventing harmful algae growth and capturing carbon through natural sinking to ocean depths. Alongside carbon removal, they benefit local ecosystems by restoring biodiversity and helping fisheries.
