Ephemeral harnesses the ocean’s ability to absorb and store CO2.

We safely remove atmospheric carbon while building coastal resilience against storms and sea level rise

Our approach accelerates rock weathering, the natural process of rainwater becoming alkalized as it returns to the sea.

We grind alkaline rock into sand and deploy it as nearshore sandbars.

As the sand dissolves, it transforms CO2 into harmless carbonates, locking carbon away for over 100,000 years.

 

 

 

 

Coastal Protection

Our sandbars protect beaches, which provide coastal communities with a physical barrier against increasingly severe storm surges and rising sea levels.

By absorbing and deflecting the energy of large waves, the structures fight shoreline erosion while preserving beaches for recreation and tourism.

 

 

 

 

 

 

Ocean Health

CO2 emissions cause ocean acidification; harming marine life, habitats, and the communities that depend on them.

Our process neutralizes this acidity, restoring ocean chemistry and preserving ecosystems.

 

 

 

 

 

Climate Justice

The regions least responsible for climate change are often the most vulnerable to its effects.

We prioritize deployments in these communities, helping them adapt to rising sea levels and more frequent storms.
