Ocean Carbon Removal Operations Underway in Nova Scotia Harbour

Planetary Technologies is conducting ocean carbon-removal operations in Halifax harbour, Nova Scotia. The company uses a process called Ocean Alkalinity Enhancement, which involves adding a chalk-like substance to seawater to increase its pH and allow it to absorb atmospheric carbon. Proponents state this process helps offset ocean acidification and will not harm local marine life, including mackerel and sea turtles. However, some marine scientists have expressed concerns about adding extra materials to the harbour waters.

The operation is part of a growing number of companies attempting to speed up natural carbon cycles in the ocean to decrease atmospheric carbon. This technology aims to rebalance ocean chemistry over long timescales. The activity raises questions regarding the environmental impact of large-scale geoengineering projects in the region.

Nova Scotia is currently focused on developing sustainable marine technology solutions, and the provincial government is providing funding to the seafood industry for energy efficiency projects.
