Overview

• UCLA and Singapore's national water agency PUB are collaborating to build the world's largest ocean-based carbon dioxide removal plant, named Equatic-1, in Singapore.
• Equatic-1 aims to remove 3,650 metric tons of CO2 annually and produce 105 metric tons of carbon-negative hydrogen, using a process involving electrolysis of seawater.
• The project, valued at $20 million, is expected to be operational by 2025 and will be built at PUB's R&D facility in Tuas, western Singapore.
• The technology could significantly contribute to global climate efforts by enhancing the ocean's capacity to absorb CO2 and producing clean hydrogen fuel.
• Concerns exist about the ecological risks of ocean-based carbon dioxide removal, prompting calls for more research into its benefits and dangers.
