Carbon to Sea Initiative

What Carbon to Sea Initiative does

Carbon to Sea Initiative is a non-profit philanthropic organization founded in 2022 that operates as the leading grant-making body dedicated to evaluating ocean alkalinity enhancement (OAE) as a carbon dioxide removal (CDR) approach. The organization funds scientific research and operates physical field research infrastructure to determine whether OAE, which accelerates the ocean's natural capacity to draw down atmospheric CO2 by adding alkaline minerals or removing acid from seawater, can safely and permanently remove CO2 at the scale required this century. It positions itself as the leading philanthropic funder of OAE research without commercial interests, and is explicitly pathway-agnostic across mineral-based and electrochemical OAE approaches, with a stated commitment to publish results regardless of whether OAE proves favorable or unfavorable.

The initiative runs four interconnected programmatic lines: Foundational Research and Technology Development (grants to scientists and engineers), Field Research Sites (a growing global network with sites in Hvalfjörður, Iceland and Halifax, Canada, plus a "Joint Learning Opportunity"), Policy & Communications (advocacy for public funding and regulatory frameworks), and Responsible Sector Development (an Annual Convening, Data Management Guidelines, and Monitoring & Verification standards). Its core "technology" is not a software product but a coordinated research framework: controlled-environment field sites that let scientists focus on science rather than logistics, combined with standards-setting activities intended to build a transparent, accountable ocean-based CDR sector.

Carbon to Sea does not sell products or services and therefore has no commercial revenue model; operations are funded by philanthropic donations and grants to researchers. Its primary "customers" are the global scientific research community and governments/regulatory bodies working on climate and ocean policy. With 1-10 employees and an Executive Director (Dr. Antonius Gagern) supported by a board of trustees, the organization functions as a small coordination and funding hub for a much larger ecosystem of grantees, partner researchers, and policy stakeholders across North America and Europe.

Core offering

Carbon to Sea Initiative is a non-profit philanthropic organization that funds and operates programs to evaluate ocean alkalinity enhancement (OAE) as a carbon dioxide removal (CDR) approach. It provides grant funding to exceptional scientists and engineers worldwide, operates a global network of field research sites (Hvalfjörður, Iceland and Halifax, Canada), advocates for policy frameworks and public funding, and promotes responsible sector development for ocean-based CDR.

Product overview

Carbon to Sea Initiative is the leading philanthropic funder of ocean alkalinity enhancement (OAE) research, operating without commercial interests. The organization operates as a unified platform for evaluating ocean-based carbon dioxide removal through grant-making and direct programs. Its portfolio consists of four interconnected components: OAE Research Funding (foundational research and technology development grants), Field Research Sites (global network of controlled research environments in Iceland and Canada), Policy & Communications (advocacy for public funding and regulatory frameworks), and Responsible Sector Development (best practices, data guidelines, and monitoring/verification standards). The initiative is outcome-agnostic, funding research regardless of whether results prove OAE favorable or unfavorable.

Direct peers

• Equatic: Commercial OAE company building one of the largest ocean alkalinity enhancement plants to date and selling carbon removal credits. Directly comparable as a parallel OAE operator, though Carbon to Sea is a research funder rather than a credit seller.
• Ebb Carbon: Commercial OAE company using electrochemistry to produce alkalinity for ocean CDR. Closest functional peer — both work on ocean alkalinity pathways to permanent CDR, divided only by funding-vs-commercial posture.
• Planetary Technologies: Early-stage company developing mineral-based ocean alkalinity enhancement for CDR. Operates in the same OAE niche Carbon to Sea funds, making it a direct technical parallel.
• Captura: Ocean-based CDR startup using direct ocean capture. Operates in the same ocean CDR category even though its electrochemical pathway differs from OAE.
• Carbon Removal Alliance: Nonprofit coalition advancing responsible policies and practices across all CDR pathways. Closest sector-organizing peer — both are nonprofit conveners shaping CDR norms, though Carbon to Sea is OAE-specific.

Broad incumbents

• Carbon180: Climate-focused nonprofit working across CDR policy, research, and deployment with a broader portfolio than OAE alone. Comparable as a climate-research/policy nonprofit, but operates across multiple CDR pathways.
• The Ocean Foundation: Major ocean-focused philanthropic nonprofit supporting marine conservation, restoration, and policy. Comparable as a mission-driven ocean nonprofit and major field-builder, though not specifically CDR-focused.
• Heirloom Carbon: Largest direct air capture (DAC) startup using limestone-based CDR technology. Comparable as a CDR operator pursuing permanent removal at scale, though operating via DAC rather than OAE.
• Climeworks: Leading commercial DAC company and biggest name in the CDR sector. Comparable as a CDR scale player whose commercial deployment creates the macro market context for Carbon to Sea's research.

Others

• Frontier (Stripe Climate): Advance market commitment purchasing CDR credits from a portfolio of suppliers. Comparable as a downstream funder/buyer in the CDR ecosystem that depends on the research advances Carbon to Sea enables.
