i2Cool Secures Series B Funding to Scale Passive Cooling Technology With Potential Maritime Applications

## i2Cool Raises Series B to Advance Passive Cooling Technology Shenzhen-based materials technology company i2Cool has secured tens of millions of yuan in Series B financing from TopoScend Capital, according to a PR Newswire announcement dated September 8, 2026. The funding round signals growing investor confidence in passive radiative cooling solutions — a technology segment with emerging relevance across energy-intensive industries, including maritime shipping. ### Use of Proceeds The company says the capital will be deployed across four priority areas: the development of standardised nanoparticle production lines, continued advancement of its core cooling technologies, recruitment of specialist talent, and commercial expansion into key global markets. Standardising nanoparticle production is considered a critical step toward making passive cooling materials commercially viable at scale — a challenge that has historically limited the technology's adoption beyond laboratory and pilot settings. ### Why It Matters for Maritime Passive radiative cooling technology, which dissipates heat without the need for external energy input, has attracted attention as a potential tool for reducing thermal loads on vessel hulls, cargo containers, and onboard equipment. As the maritime industry faces intensifying pressure to cut fuel consumption and greenhouse gas emissions under IMO decarbonisation targets, energy-free cooling solutions could offer an incremental but meaningful contribution to overall efficiency gains. While i2Cool has not publicly detailed specific maritime partnerships or vessel-based deployments, the company's stated focus on 'priority global markets' and standardised manufacturing suggests a strategic push toward industrial-scale clients — a category that includes shipowners, port operators, and logistics infrastructure providers. ### Company Background i2Cool is a spinout rooted in advanced materials research, specialising in nanoparticle-based coatings and films engineered to reflect solar radiation and emit heat into the atmosphere. The technology operates without electricity, positioning it as a complementary solution alongside active cooling and energy management systems. TopoScend Capital, the lead investor in this round, focuses on deep-tech and advanced manufacturing investments in the Chinese market and internationally. ### Outlook With Series B funding now secured, i2Cool is expected to accelerate both its production capacity and its business development pipeline. Industry observers will be watching whether the company moves to formalise partnerships within the maritime and offshore sectors, where hull coating innovation and thermal management remain active areas of commercial interest. *Source: PR Newswire*
