Equatic押注海洋碳去除可规模化，在新加坡建造全球最大工厂
UCLA孵化的Equatic将一项100万新元挑战赛奖金转化Equatic-1，这是全球最大的海洋碳去除工厂，计划于2026年第一季度在土司启动。
Equatic
做的是什么生意
Equatic, an American startup founded out of UCLA, removes carbon dioxide from seawater with a patented electrolysis process that also produces green hydrogen; it sells carbon-removal credits and hydrogen while building demonstration and commercial plants with national partners.
启动资金：Equatic won S$1 million from Temasek Foundation's The Liveability Challenge in 2021 as SeaChange; the Equatic-1 plant is a US$20 million facility co-funded by PUB, Singapore's National Research Foundation and UCLA's Institute for Carbon Management; a US$11.6 million Series A closed in August 2025.
起因
Equatic was founded around research at UCLA's Institute for Carbon Management and entered Singapore through Temasek Foundation's The Liveability Challenge in 2021, winning S$1 million in catalytic funding under its former name SeaChange. The premise was that the ocean, which already absorbs roughly 30% of human CO2 emissions, could absorb more if chemistry changed the seawater being returned to it — a route to carbon removal that does not compete for land the way forests or direct-air-capture plants do.
经过
Two pilot plants, one at PUB's desalination research site in Tuas and one at the Port of Los Angeles, began removing 100 kg of CO2 per day in April 2023. Equatic then committed to Equatic-1: a US$20 million demonstration plant at Tuas co-funded by PUB, Singapore's National Research Foundation and UCLA, designed to start at 1 tonne of CO2 per day and scale to 10 tonnes — roughly the annual tailpipe output of 870 cars — while producing about 300 kg of hydrogen daily. The schedule slipped from an original late-2024 target while system designs were finalized, and on 2025-08-11 the company closed a US$11.6 million Series A led by Temasek Trust's C3H with Kibo Invest as co-lead, earmarked for engineering its first commercial-scale, 100-kilotonne facility.
结果
As of late August 2025 Equatic-1 was still expected to begin operations in the first quarter of 2026, with initial installation phases due to start by end-September 2025; the company was simultaneously engineering its first commercial-scale carbon-removal facility in North America, and counted Boeing among buyers of its carbon-removal credits.
背景
Equatic是一家源自UCLA碳管理研究所的美国初创公司，押注海洋可以成为可扩展的碳去除机器。其专利海水电解技术从附近海水淡化厂吸入的海水中去除溶解二氧化碳——将其转化为类似石灰石的固体，可固定气体超过一万年——而同一过程将水分解为氢气，为公司提供第二产品。
公司通过淡马锡基金会“宜居挑战赛”进入新加坡，2021年以SeaChange名义赢得100万新元，并于2023年4月通过两个试点证明技术，每个试点每天去除100公斤二氧化碳。随后公司承诺建设Equatic-1，一座价值2000万美元的示范工厂，位于土司，由国家水务机构PUB、新加坡国家研究基金会和UCLA共同资助，设计从每天1吨扩大到10吨二氧化碳，同时产生约300公斤氢气。
原定2024年底的时间表出于设计定稿而延迟，运营预计在2026年第一季度。2025年8月，Equatic完成1160万美元A轮融资，由Temasek Trust的C3H平台领投，新加坡投资办公室Kibo Invest联合领投——公司计划利用这笔支持工程化其在北美的首个商业规模10万吨级设施——同时专家警告海洋碳去除方法仍年轻，必须监测其对海洋化学和海洋生物的影响。
这件事要成立，得有什么
- 海洋已经吸收约30%人类二氧化碳排放，因此增强这一自然汇可避免植树和直捕对土地和水资源的需求。
- 在同一电解步骤中产生氢气为实现该过程提供第二收入流，使碳去除不仅作为信用购买方的纯成本。
- 与PUB合作使Equatic获得实际基础设施、监管监督和技术可信赖的归宿，该技术需证明可在工程规模运行而非仅实验室。
- 示范工厂特意先于商业工厂：Equatic-1每天10吨的产出是为A轮融资所工程化的10万吨设施进行预演。
可借鉴之处
气候初创公司可以以里程碑换取合作伙伴：PUB的名称、场地和共同出资为这项新颖海洋技术提供了营销无法购买的机构信誉。
后续进展
截至2025年8月24日，Equatic处于里程碑之间：土司Equatic-1由于设计的延期预计2026年第一季度启动，8月11日宣布的1160万美元A轮融资正在资助其首个商业级北美设施的工程。其ISO 14064监测经Isometric和Puro.earth注册处验证，支撑出售给波音的信用；2024年Earthshot决赛入围地位使土司工厂成为考验海洋碳去除是否在监管机构和科学家接受的规模上有效的标杆。
