Request for Proposals: Ocean-Based Carbon Dioxide Removal Analogues

The ClimateWorks Foundation supports research grants to help close key knowledge gaps to advance ocean-based carbon dioxide removal (CDR), and to catalyze public and philanthropic interest in this field of research. Ocean Visions has a multi-pronged program to support accelerated research and development of ocean-based CDR. Together, ClimateWorks Foundation and Ocean Visions seek to award up to two,18-month grants to evaluate the effectiveness and environmental impacts of ocean-based CDR approaches via the study of field-based analogues. Ocean-based CDR analogues are defined as marine settings that remove carbon dioxide (CO2) from the atmosphere via processes that could theoretically be replicated, accelerated, and scaled.

The grant size of a project proposal should not exceed $220,000. However, if there is a compelling reason for this RFP to support one large project (up to $440,000), applicants are invited to make that case in their proposal form.


To achieve climate targets set out in the Paris Accords, very large quantities of CO2 must be removed from the atmosphere. The ocean is Earth’s largest CO2 sink due to its various natural biological and geochemical processes. Such processes could potentially be replicated, amplified, and scaled in order to sequester atmospheric CO2 faster than would otherwise occur naturally.

Based largely on theoretical work or very small experiments, ocean-based CDR approaches have shown the potential to capture significant amounts of CO2. Ocean Visions’ road maps to accelerate the development and testing of ocean-based CDR approaches have identified the critical role of small, controlled field trials in providing real-world evidence of carbon sequestration potential, environmental co-benefits, and environmental risks. Yet there remain social, legal, and economic barriers that are slowing the initiation of field trials. As a stepping stone, ocean CDR analogues can serve as an opportunity to evaluate efficacies of CDR and environmental impacts of specific approaches.

Ocean-based CDR analogues are defined here as marine settings where the effects of ocean-based CDR approaches can be investigated due to a similarity in the process of carbon capture and storage, which would give insight to the CDR capacity and environmental impacts if that process were accelerated and scaled. Analogues may be nature-based (e.g., natural deposition of macroalgae in deep ocean environments) or a consequence of a historic or present-day anthropogenic activity (e.g., alkalinity flux into the ocean due terrestrial liming).

Projects evaluating CDR in blue carbon ecosystems (mangroves, seagrasses, salt marshes) fall outside the scope of this RFP.


Projects should identify a field-based ocean CDR analogue and:

  • Quantify atmospheric CO2 flux into the ocean, and
  • Evaluate environmental co-benefits and environmental risks of the process that removes CO2 from surface waters.

Methods should focus on in-situ observations, however, where data are already available but have not yet been synthesized or incorporated into models to inform CDR effectiveness and environmental impacts, desk research is a possibility as well.

Peer-reviewed scientific publications will ultimately be expected, but by the end of the grant duration (18 months) grantees should be prepared to produce a project summary that addresses the following topics:

  • How the analogue improves our understanding of carbon sequestration, permanence, environmental co-benefits, and environmental risks in that environment.
  • Critical physical, biological, and chemical properties of interest that affect the CDR capacity, environmental co-benefits, and environmental risks of the analogue.
  • Lesson learned from this analogue that could inform the design of controlled, experimental field trials, including measurement tools and data infrastructure needs.


Applicants can be from any country. Applicants must submit a pre-proposal, which will be evaluated by ClimateWorks Foundation and Ocean Visions staff. A subset of applicants will be selected and invited to submit a full proposal. Full proposals will be peer-reviewed by an Advisory Committee selected by Ocean Visions.

Applicants can use this RFP to co-fund and expand the scope of an existing project, as long as that project fulfills the scope of this RFP.

Applicants may submit or be part of more than one pre-proposal.

This Request for Proposals is generously supported by funding from the ClimateWorks Foundation Carbon Dioxide Removal (CDR) Program, and undertaken in partnership with Ocean Visions’ Ocean-Based CDR Program. Among other roles, OV will convene expert review panels as part of the process. ClimateWorks launched the CDR Program in 2018 to catalyze and promote the CDR field. In addition to working on terrestrial carbon dioxide removal issues, the CDR Program supports research to address key scientific gaps as well as major community-building initiatives to bring to light the ocean’s potential role in CO2 removal.

Product Aims to Accelerate Development and Testing of Macroalgae-Based Carbon Sequestration

Ocean Visions’ new “living” digital road map allows for global crowdsourcing approach

Ocean Visions today released the first in a series of five “living” digital road maps that identify specific pathways forward to accelerate the development and testing of ocean-based carbon dioxide removal approaches.

The first of these maps—the Macroalgae Cultivation and Carbon Sequestration Road Map—was introduced to potential users at the 2021 Ocean Visions Summit.

During 2020, Ocean Visions convened experts from multiple disciplines, sectors, and geographies to build these road maps. Numerous workshops helped to identify technology readiness, scaling potential, uncertainties, obstacles, opportunities, and first-order priorities for moving the field forward. The effort focused on three ocean-based carbon dioxide removal (CDR) domains, as well as two cross-cutting issues of importance.

These road maps are intended to catalyze attention and action around the most critical priorities to move these fields forward. The road maps will be regularly updated and refined as advances emerge in science, technology, governance, and policy.

Carbon dioxide removal (CDR) is increasingly acknowledged as an imperative for slowing climate change, in lockstep with reducing emissions. To date, however, most of the development around CDR approaches and technologies has been focused on terrestrial solutions, such as afforestation.

“Removing legacy carbon pollution from our air and water is essential to a healthy ocean, and to interrupting dangerous warming and acidification. The ocean represents an enormous opportunity to sequester carbon, but ocean-based carbon dioxide removal approaches are poorly understood and underinvested,” says Ocean Visions Executive Director and Chief Innovation Officer Brad Ack. “These road maps are designed to help overcome those obstacles.”

The cultivation of macroalgae, or seaweed, has the potential to play a critical role in sequestering carbon. While there are a number of emerging pilot initiatives, a supportive framework is lacking. The road maps are intended to provide this framework, allowing scientists, engineers, cultivators, entrepreneurs, investors, philanthropists, and more to collaborate across the globe to drive progress on the most critical priorities for scaling the field.

“This new road map will help a multisector community better understand and assess challenges and opportunities related to field testing, commercial scaling, philanthropic engagement, and public support—all grounded in an evidence-based, precautionary approach towards implementation,” Ack says.

Support for the suite of open-source digital road maps comes from ClimateWorks and Schmidt Marine Technology Partners.

Ocean Visions 2021 Summit to Showcase and Explore Diverse Solutions for Pressing Ocean Challenges

Prominent researchers, innovators, decision-makers, and funders will discuss new road maps for ocean-based solutions to the climate crisis, equitable solutions for coastal inundations and sea level rise, development of marine circular economies, and much more.

The Ocean Visions 2021 Summit, “Towards a Global Ecosystem for Ocean Solutions,” will be held May 18-21, 2021. The biennial Summit will feature prominent researchers, innovators, decision-makers, and funders—all of whom are working to accelerate solutions for the greatest challenges facing our ocean.

Against the backdrop of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030), this year’s summit will convene a diverse community on the cutting edge of creating and advancing solutions in the ocean-climate nexus.

Opening the four-day summit with a conversation on catalyzing ocean solutions is Scripps Institution of Oceanography Director Margaret Leinen, Georgia Tech College of Sciences Dean and American Geophysical Union President Susan Lozier, Woods Hole Oceanographic Institution President and Director Peter de Menocal, Chairman of Ocean Visions and Georgia Tech Ocean Science & Engineering Director Emanuele Di Lorenzo, Co-Founder of the Early Career Ocean Professional network under the UN Decade Erin Satterthwaite, and Ocean Visions Executive Director & Chief Innovation Officer Brad Ack.

The Ocean Visions 2021 Summit is expected to bring together more than a thousand participants from many parts of the globe to engage in meaningful conversations on the most effective approaches to address the major ocean-climate challenges. Sessions include:

· Accelerating the Ocean’s Power to Sequester Carbon and Reverse Climate Disruption

· Equitable Solutions for Coastal Inundations and Sea Level Rise

· Healthy Ocean & Healthy People

· Marine Circular Bioeconomy: Sustainable Food, Bioenergy, & Biomaterials

· Harnessing Innovation to Accelerate Ocean Solutions

· Towards a Global Ecosystem for Ocean Solutions (GEOS)

“We used to think the ocean was beyond human’s ability to affect; we now know that our ocean is under enormous stress from an ever-expanding human footprint. From overfishing, habitat alteration, and a host of pollutants flowing into the ocean, to the existential threats posed by too much carbon dioxide in the atmosphere and the ocean, we desperately need the power of human ingenuity to redesign the systems causing the pain,” says Brad Ack, executive director & chief innovation officer at Ocean Visions. “This conference is all about that re-design; breaking down the silos that exist among research universities and institutions, professional ocean-focused societies, NGOs, IGOs, foundations, business and financial institutions to work together on new solutions.”

The Ocean Visions 2021 Summit is complimentary to attend. Registration is required to have access to the virtual summit portal. For more details on the program and to register, please visit:

Ocean Visions’ Experts to Advise/Evaluate Innovation Tackling Ocean Acidification

Pilot project will develop new electrochemical approach to mitigate ocean acidification and enhance ocean-based carbon sequestration

Ocean Visions today announced an advisory relationship with The College of Engineering and Applied Sciences at Stony Brook University to pilot and evaluate a new approach aimed at mitigating ocean acidification and enhancing ocean carbon sequestration. The project, Safe Elevation of Alkalinity for the Mitigation of Acidification Through Electrochemistry (SEA MATE), will use electrochemistry to remove acids from the ocean.

During the 2021 phase of the pilot, SEA MATE will prototype an acid removal technique to combat ocean acidification. An additional anticipated benefit of the SEA MATE process is the capture of atmospheric carbon dioxide and its safe long-term sequestration in the ocean as bicarbonate. Ocean Visions has assembled an Expert Team to provide scientific review and guidance on the design of experiments, data analysis, hypothesis testing, and safe operating thresholds. The team will ultimately produce an independent evaluation of the overall potential of the approach, including environmental costs and benefits.

The effort is supported through a partnership between the Jeremy and Hannelore Grantham Environmental Trust (GET) and Ocean Visions to identify and test technology-based solutions to climate impacts in the ocean. The partnership is founded on shared missions to slow, and ultimately reverse, the planet’s climate crisis.

“Excess carbon dioxide in our air and the ocean is causing dramatic disruptions to our planet; cleaning up this pollution is critical to restore our ocean,” says Brad Ack, executive director & chief innovation officer for Ocean Visions. “SEA MATE is a promising approach to address one of the most critical impacts of this carbon pollution – ocean acidification – while also tackling the direct cause of too much carbon dioxide in the air and water.”

“We clean up after oil spills, we should also clean up the ‘acid spill’ caused by carbon dioxide emissions,” says Dr. Matthew Eisaman, assistant professor in the Department of Electrical and Computer Engineering at Stony Brook University, and SEA MATE project lead.

Together with Dr. Brendan Carter, a principal investigator and research scientist with the University of Washington, Eisaman will share SEA MATE plans and findings with the Ocean Visions’ Expert Team, which will provide external, third-party review and guidance directed at increasing the probabilities of safe, successful outcomes and subsequent deployment. Specifically, the Ocean Visions’ Expert Team will:

  • Review SEA MATE’s research and development plan and provide feedback and advice on ways to optimize the design and implementation of the research and development plan to maximize overall performance, efficacy, and data integrity.
  • Review potential environmental risks and benefits and upstream and downstream impacts of the electrodialytic process and advise on how to minimize any potential negative impacts and maximize positive impacts.
  • Provide review and advice on design of monitoring systems and protocols to measure overall performance, and, in particular, carbon sequestration and environmental impacts of the electrochemical process developed by SEA MATE.
  • Review results of the laboratory testing, field tests, and model results as they become available.
  • Provide publicly available intermediate and final evaluation reports of the SEA MATE process. These reports will review the overall effort, the validity of the findings, any areas of disagreement and suggested next steps with respect to the research and development plan.

Ocean Visions’ Expert Team members include Dr. Ellen Briggs, Dr. David Ho, Dr. Kristy Kroeker, and Dr. William Tarpeh. Dr. David Koweek, Ocean Visions Science Director, is overseeing the effort.

Cleaning up the most dangerous pollutant

With help from Schmidt Marine Technology Partners, Ocean Visions is working to accelerate the pace of marine carbon dioxide removal

Reposted from Schmidt Marine Technology Press

Every second of every day, the equivalent of five Hiroshima-sized bombs’ worth of heat energy is absorbed by the ocean—the result of greenhouse gasses put into the air by human activities. “The oceans are absorbing a staggering amount of heat,” says Brad Ack, a Schmidt Marine Technology Partners’ grantee and executive director of Ocean Visions. “This silent catastrophe is destroying much of what we care about in the ocean.” Additionally, the ocean absorbs about 30% of human-caused carbon pollution.

Together, excess heat and carbon dioxide are bleaching corals, melting sea ice, and acidifying the sea at alarming rates. Yet few organizations are addressing the root cause of these problems. That’s where Ocean Visions comes in. Founded in 2019 by a dozen of the world’s most respected ocean science organizations, including the Scripps Institute of Oceanography and Stanford University, Ocean Visions is a research consortium and network dedicated to solving to the ocean’s most pressing problems—starting with the carbon dioxide pollution that’s leading to rapid warming and acidification.

A new path, backed by science

Until recently, most efforts to mitigate climate change have focused on stemming the flow of greenhouse gasses emissions into the atmosphere. But the Intergovernmental Panel on Climate Change says that alone, turning off the tap won’t keep global warming from exceeding 1.5 degrees Celsius. We also need to remove billions of tons of “legacy” carbon dioxide already poisoning our air and water.

To that end, Ocean Visions’ first goal is to identify the most promising technologies for increasing the ocean’s capacity to sequester and permanently store carbon dioxide in marine environments. While carbon dioxide removal (CDR) is beginning to gain acceptance as a critical tool, removing carbon dioxide from the ocean has remained relatively underexplored compared to terrestrial approaches. Yet the ocean holds enormous potential to increase it’s already-outsized role in carbon cycling, and to do so by mimicking and enhancing natural and geological processes already underway.

Ocean Visions is taking a leadership role in drawing attention and resources towards a methodological approach to technology development, backed by top scientists and conservationists. So far, the team has is working on three main focus areas. The first is cultivating macro-algae, such as giant kelp, which removes carbon from the ocean in the same way that trees remove carbon from the atmosphere.

The second is adding alkaline substances, such as lime or natural minerals, to the ocean to reduce acidity. Known as ocean alkalization, this process converts marine carbon dioxide to other, harmless molecules. The ocean then sucks more carbon dioxide from the air to restore equilibrium.

The last method is separating carbon dioxide from seawater using electrochemical processes, similar to the way direct air capture technology removes carbon dioxide from the atmosphere.

Ocean Visions isn’t deploying these technologies itself. Instead, it’s providing a platform for researchers, businesses and others to work together on the highest priority developmental areas to ultimately figure out if these are, in fact, sustainable, equitable and scalable solutions for reducing carbon dioxide pollution in the world’s oceans.

Mapping the future of carbon dioxide removal

Schmidt Marine is providing vital support for Ocean Visions’ work. In summer 2020, Schmidt Marine helped fund a series of workshops hosted by Ocean Visions, in which experts identified the current state of each technology, the challenges and obstacles each face, the social and environmental costs and the next steps. The findings will soon be published in an open-source online roadmap. Researchers, inventors and entrepreneurs will be able to pull from and add to the map, eventually advancing carbon dioxide removal technologies toward testing, deployment and commercialization.

“Essentially, Schmidt’s funding is pivotal in the development of technology roadmaps,” Ack explains.

Over the next decade, Ack hopes that these roadmaps will help move ocean-based carbon dioxide removal from an undervalued tool to a widely-deployed strategy in the fight against climate change. It’s a shift that can’t come soon enough. “The ocean has shielded humanity and terrestrial biodiversity from the worst ravages of climate change so far, but it has borne an enormous cost in doing so,” he says. “It’s continuing to bear that cost, but its tolerance is running out.”

Ocean Visions Expert Panel to Advise & Evaluate Carbon Dioxide Removal Experiment

Ocean Visions works to transform science and engineering into scalable, equitable, and sustainable ocean solutions.  In furtherance of this mission, Ocean Visions has partnered with the Grantham Environment Trust to evaluate and advance effective ocean-based climate solutions.  Under this agreement, Ocean Visions and the Grantham Environmental Trust work together to evaluate the science and engineering of proposed ocean-climate innovations, and Ocean Visions provides third-party advice and assistance on research, development, field testing, impact analysis, and optimization to Grantham Environmental Trust grantees.

New Partnership to Deploy Ocean-Based Solutions to Climate

The Jeremy and Hannelore Grantham Environmental Trust (GET) and Ocean Visions Inc. (OVI) are pleased to announce a partnership to identify and test technology-based ocean-climate solutions.

This new partnership is founded on shared missions to work to slow, and ultimately reverse, the climate crisis our planet is confronting.  Both organizations understand that while reducing current and future emissions of CO2 is urgent and necessary, it is no longer sufficient. Even with dramatic reductions in global emissions, hundreds of gigatons of carbon dioxide will still need to be safely removed from the atmosphere and ocean. Large-scale carbon dioxide removal (CDR) is essential to arresting climate disruption and achieving climate restoration.

The GET/OVI partnership is focused on the identification, development, testing and, ultimately, potential deployment of ocean-based technologies that can draw down CO2 from both the atmosphere and the ocean.  The partners agree on the tremendous potential role the ocean can play in CO2 removal and permanent, safe storage.

Ocean-based CDR technologies are much less developed than land-based alternatives, but there are a number of promising ocean-based approaches including large-scale macroalgae (seaweed) cultivation, microalgae cultivation, ocean alkalinity enhancement, artificial upwelling and downwelling, and others.  More pathways will be developed over the coming decades, and each will require careful assessment.

This GET/OVI partnership is not prejudging approaches or outcomes but is based on the principle that evaluation and understanding of ocean/climate solutions needs to be accelerated.  Each potential solution needs input and energy from different scientific and engineering disciplines to move this important field forward.

This partnership brings together the intellectual and institutional capacity of universities and research institutions with the skills of inventors, entrepreneurs, investors, and civil society.  The partners will:

  • Review and validate the science and engineering of particular opportunities.
  • Provide guidance on risks, risk avoidance, validation frameworks, upstream and downstream impacts, and lifecycle analysis.
  • Advise on the design of monitoring and evaluation frameworks.
  • Collaborate on trials and experiments needed to evaluate technologies and their impacts.

An important element of this OV/GET partnership is the broad spectrum of GET’s potential funding. Depending on stage, GET is able to fund applied research, sponsored research and make early, patient investments. Any investments will be made as part of GET’s Neglected Climate Opportunities program and any proceeds from such investments will, in turn, all be used to fund climate-related grantmaking.

OVI and GET are together committed to objective and rigorous scientific analysis, collaboration, and openness as we move this partnership forward.  If you would like to be involved, or just to be kept informed, join the Ocean Visions mailing list or email any request to
