the future is here.

1. Reverse Osmosis

The process begins with a stream of concentrated brine. Heimdal uses reverse osmosis, or seawater desalination, as an access point for salt-concentrated water.

2. Electrolysis

An electrochemical cell separates the brine, extracting acids in the form of hydrochloric acid.

3. Reintroduction

The de-acidified solution is returned to the oceans.

4. De-acidification

The de-acidified seawater reacts with carbon dioxide through the ocean-atmosphere gas exchange, rebalancing the oceans pH to pre-industrial levels

5. Mineralization

When this interaction occurs above the calcite compensation depth (CCD), it prompts the restructuring of dissolved carbon dioxide into calcium and magnesium carbonates.


As de-acidified brine reacts with dissolved CO2 and prompts the mineralization process, it also enables the oceans to absorb more carbon dioxide from the atmosphere. This provides immediate relief to rising CO2 levels in the atmosphere and the ocean simultaneously, while safely and naturally sequestering it for hundreds of thousands of years.
