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

We safely remove atmospheric carbon by accelerating rock weathering, the natural process of rainwater becoming alkalized as it returns to the sea.

Oceanic Enhanced Weathering

We grind alkaline rock into sand and deploy it in ocean waters.

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

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, fostering job creation, education, and climate resilience by tailoring projects to local needs.
