Seawater carbon removal: Building world’s largest demonstration plant in Singapore
Following two successful pilot projects, Singapore national water agency, PUB and Equatic will build the world’s largest ocean-based carbon dioxide removal plant in Tuas, Singapore to demonstrate and test the technology’s effectiveness and potential future scalability.
Singapore's PUB and Equatic are set to construct the world's largest ocean-based carbon dioxide removal plant in Tuas, aiming to demonstrate its effectiveness and scalability by mid-2024. Equatic's innovative process generates carbon-negative hydrogen while removing CO2 from seawater, potentially enhancing the ocean's carbon absorption capacity. As part of Singapore's net-zero ambitions, the plant underscores PUB's commitment to sustainable water management and reducing emissions.
The plant, leveraging modularity and scalability, aims to remove 10 metric tons of CO2 daily, with the potential to remove 10 billion tons annually. Powered by renewable energy, it aligns with PUB's strategy to reduce energy consumption and advance sustainability. The success of this pioneering project could set a precedent for transformative climate action worldwide.
TECH DIVE: Membranes and the anti-fouling holy grail
From water purification to pharmaceutical production, membrane technology plays a crucial role in various industries. We highlight some of the latest developments to combat fouling associated with the process and companies reshaping the landscape of membrane technology.
Membrane technology is vital in various industries, but fouling remains a significant challenge. Dr. Graeme Pearce highlights unmet needs in seawater RO and removing persistent organics like PFAS. Despite advancements, fouling persists, spurring innovation in alternative materials like ceramics and graphene. Biomimetic membranes, nanotechnology integration, and smart membrane technology are being developed to enhance efficiency and sustainability.
Companies like ZwitterCo, Hydranautics, NX Filtration, and Dupont are pioneering solutions to combat fouling, from BWRO membranes to biostatic environments. These innovations, alongside ongoing research, promise continued progress in membrane technology, addressing pressing environmental challenges across industries.

Day Zero: Will Mexico City run out of water?
Mexico City, home to over nine million people, with more than 22 million living in its metropolitan area, is running out of water. It is also sinking.
Mexico City, home to over nine million people and with over 22 million in its metropolitan area, faces a dire water crisis compounded by sinking land. Conflicting narratives debate the immediacy of "Day Zero," with some predicting imminent water depletion while others suggest the city can endure for a few more years. The crisis stems from a convergence of factors: climate change-induced drought, urban infrastructure vulnerabilities, and overexploitation of the aquifer beneath the sinking city. Efforts to mitigate the crisis include reductions in water flow from external sources and investments in infrastructure improvements, but long-term sustainability remains uncertain without collaborative, innovative solutions.
Despite proactive measures by local authorities and agencies to address immediate concerns, Mexico City's water crisis persists, demanding unified action from local, national, and international stakeholders. As the city grapples with the complexities of climate change, geological challenges, and infrastructure vulnerabilities, achieving a sustainable water future requires innovative, lasting solutions and collective commitment across communities and industries.
