Growing Innovation Beneath the Waves

Ocean Grows Limited is a Hong Kong-based social enterprise dedicated to advancing sustainability through marine innovation, education, and environmental restoration. Founded with a mission to address climate change and food insecurity, we focus on unlocking the vast potential of the ocean—through underwater farming, algae cultivation, and STEM education that connects people with the planet.

Our work begins beneath the water. We are developing one of Asia’s first underwater cultivation systems, capable of growing not only algae but also herbs, leafy greens, and other vegetables in a controlled marine environment. These systems are designed to conserve freshwater, reduce land use, and capture carbon—creating a climate-resilient food source while restoring marine ecosystems.

At the heart of our approach is algae, one of nature’s most powerful resources. In partnership with researchers from The University of Hong Kong and algae farming specialists in Taiwan, we cultivate various algae species for environmental, nutritional, and material applications. Our pioneering Ocean Brick project, for example, explores the use of algae extracts to create sustainable construction materials that are strong, insulating, and low-carbon.

Beyond technology, we believe education is key to long-term impact. Ocean Grows has developed a suite of STEM learning programs, sustainability workshops, and algae-themed experiences for schools, corporates, and the public. We’ve collaborated with leading institutions, including Ocean Park Hong Kong, to deliver marine education in a fun, hands-on format that nurtures environmental literacy and action.

Through innovation, collaboration, and community outreach, Ocean Grows Limited is not just farming the ocean—we’re cultivating a movement. A movement toward carbon neutrality, marine regeneration, and a deeper respect for the planet we call home.
