ImpactAlpha, March 22 — Nova Scotia-based Planetary Technologies adds alkalinity to the ocean to resist acidification and enhance the seas’ natural ability to sequester carbon from the atmosphere.
Planetary (formerly Planetary Hydrogen) says the process enables the ocean to store carbon for tens of thousands of years and reverses damage caused by acidification due to climate change.
The company has raised $7.8 million to launch pilot facilities in Quebec and Nova Scotia. Shopify has pre-ordered some of the credits Planetary aims to remove with the facilities. Leftover purified alkaline rocks can produce zero-carbon green hydrogen fuel, the company says.
