Deep Sky, a Canadian carbon removal project developer, has partnered with Equatic, an ocean carbon capture company, to begin construction of the first commercial-scale ocean-based carbon dioxide removal (CDR) plant in Quebec, Canada.

The plant, which is said to be capable of removing 109,500 tons of carbon dioxide from the atmosphere annually while producing 3,600 tons of green hydrogen, is slated to be the world's largest ocean-based carbon removal facility. Furthermore, the facility is expected to support Equatic to reach its carbon dioxide removal target at less than USD 100 per ton by 2030. 

The plant’s design will be based on the modular electrolyzers used at Equatic-1, Equatic’s recently unveiled demonstration project in Singapore. The modular architecture allows the installation, operation, and maintenance of individual units to be staged and stacked, facilitating systematic rapid expansion and efficient operations. The plant is expected to be operational between 2026 and 2027.
