Carboniferous

‍Preserving plants to remove carbon dioxide‍

Carboniferous stores unused plant matter in naturally occurring, underwater brine pools to keep carbon out of the atmosphere – permanently.

Get in Touch Our Approach

Validating sequestration in deep hypersaline anoxic basins.

Scaling to 1M metric tons of per year of carbon dioxide removal.

Sequestering 1Gt+ of CO2 per year.

OUR PROCESS

Marine Anoxic Carbon Storage (MACS) is a process for large-scale carbon dioxide removal (CDR).

We preserve excess biomass, e.g. unused plant stalks left over after agriculture processes, in extremely salty, oxygen-free (anoxic) basins in the ocean's floor. This dramatically slows the rate of decomposition, preventing carbon from re-entering the atmosphere.

HOW PLANTS FIX CARBON

MACS relies on the natural process of photosynthesis to remove carbon.

Plants absorb CO2 as they grow in the spring and summer. The plant absorption rate exceeds that of man-made emissions.
‍
Plants release CO2 as they decompose in the fall and winter.
‍
By arresting that state of decomposition, Carboniferous's MACS approach — the preserving of agricultural plant stalks in anoxic basins — is removing C02 from the atmosphere for at least 1,000 years.
