Seawater restoration
to rebalance the climate

Why Seawater Restoration Matters
The ocean is one of Earths most powerful climate allies, absorbing about a quarter of the carbon dioxide we emit each year. But as emissions rise, the ocean is reaching a breaking point.
Coastal waters, rich in life and vital to local communities, are becoming more acidic, harming ecosystems and weakening the oceans natural ability to regulate the climate.
Planetary is working to fix this imbalance. We restore the chemistry of seawater so it can do what it has always done: support life and protect the planet.
How Our Process Works
Planetarys seawater restoration process uses ocean alkalinity enhancement (OAE).
We introduce purified alkaline minerals into coastal outfalls at existing infrastructure sites, such as powerplants or wastewater treatment facilities.
This boosts the waters buffering capacity, allowing the water to convert more atmospheric carbon dioxide into stable bicarbonate.
The result of this process is permanent carbon removal, reduced ocean acidity, and stronger marine ecosystems.
Reforestation accelerates carbon dioxide removal on land.
Seawater restoration increases removals on our coasts.
Partners
OCP: Our Process
Our Ocean Carbon Platform
High-Purity Minerals
We recover natural alkaline minerals from industrial byproducts using our patented process.
Infrastructure Integration
We introduce minerals to water flowing through existing coastal facilities like wastewater and power plants,
reducing acidity and restoring balance
Scientific Oversight
We partner with academic institutions and regulators to ensure safety and performance.
Third-Party Verification
We measure the outcomes of our projects and submit the results to third-party verifiers to produce high quality, certified carbon removal credits
Code of Conduct
Planetary is committed to developing OAE that is ethical and sustainable by all metrics.
Our Code of Conduct was written to guide all our work, including our project development and our lab science. It applies to everyone who participates in this work with and on behalf of Planetary.
In every stage of our operations we strive to be:
- Safe
- Impactful
- Science-Driven
- Engaged
- Transparent
Safe
We follow the laws, rules, and guidelines in every region where we operate. In jurisdictions with weak regulatory requirements, we conduct our operations in line with emerging best practices for deployment.
Impactful
We focus our science and operations on measurably and safely reducing atmospheric CO2. The environmental impact of our work is the primary measure of our success, and we prioritize it even in cases where it may not maximize profitability.
Science-Driven
We collaborate with world-class scientific institutions and researchers to evaluate the safety and effectiveness of our methods in managing CO2. Our research strives to be rigorous, responsible, and relevant and takes active steps to reduce research bias and increase accuracy, using third party verification when possible.
Engaged
We proactively seek out dialogue with stakeholders, including local communities at each project site. We address concerns and work with stakeholders to achieve shared success and address unforeseen issues.
Transparent
We measure, verify, and share the results of our testing and the ongoing environmental impacts of our developments.
