Gigablue is currently conducting a trial off the Otago coast as part of its push for regulatory changes to allow marine carbon storage in New Zealand. The company has proposed alterations to marine regulations to proceed without consents, aiming for commercial viability while generating scientific evidence.
However, the Environmental Protection Agency (EPA) rejected two applications from Gigablue in late 2025, citing concerns over illegal dumping and environmental effects. Despite these setbacks, Gigablue received permission for a modified trial involving 55 kg of substrate.
Experts warn that marine carbon removal technologies require rigorous validation, emphasizing a cautious approach to commercialization. New Zealand's regulatory framework and adherence to international agreements, such as those prohibiting ocean fertilization, remain critical to the operation's future.
