Ocean-Based Climate Solutions

We are catalyzing and supporting research and development for carbon dioxide removal technologies that build on the ocean's natural processes.

Ocean-Based Carbon Dioxide Removal: Road Maps for Research, Development and Demonstration

The ocean safely holds more carbon than any other part of the biosphere and has the potential to contribute even more to removing and safely storing carbon. While the ocean has enormous potential for carbon dioxide removal (CDR), and there are a number of emerging ocean-based carbon dioxide removal approaches, a great deal more research, development, and evaluation is urgently needed. To help focus and facilitate action, Ocean Visions worked with experts from around the globe to develop five interactive and ‘living’ road maps that identify key actions needed to advance our collective knowledge of ocean-based CDR pathways. This knowledge is critical to determining what role, if any, each may ultimately play in addressing the climate crisis.

Supporting Innovation

Ocean Visions supports innovation and the creation of new potential solutions at the ocean-climate nexus. We provide tailored expert support to selected competitors for the $100M XPRIZE Carbon Removal through the Ocean Visions Launchpad, which helps to test and validate team technologies and business models in order to improve their chance of success. We also advise and evaluate selected innovators through direct technical assistance and third-party evaluation.

Building Community

A growing number of scientists, entrepreneurs, policymakers, NGOs, and foundations are exploring methods that could boost the ocean’s capacity to remove carbon dioxide (CO2) from the atmosphere. The Ocean CDR knowledge hub brings together stakeholders to advance the state of knowledge, build bridges across disciplines, and help the community move towards testing and piloting the most promising ocean-based carbon dioxide removal approaches.


Learn more about the various types of ocean-based carbon dioxide removal approaches: artificial downwelling, deep sea storage, electrochemical ocean capture, macroalgal cultivation, marine ecosystem restoration, microalgae cultivation, and ocean alkalinity enhancement. And explore our new section in Frontiers of Marine Science – Ocean Solutions. The goal of the Ocean Solutions section is to develop an integrated and adaptive knowledge base of ocean solutions research that will facilitate the translation of science and engineering into applied solutions at regional and global scales.
