Sungreenh2

SunGreenH2 is a Singapore-based cleantech/advanced-materials company that develops nanoengineered electrodes, porous transport layers (PTLs) and electrolyser cell stacks for electrochemical water splitting. Its core technology, marketed as the NanoFuzeX platform, metallurgically fuses catalyst material into a porous metal substrate without a polymer binder, which the company says preserves the catalyst nanostructure while maintaining full metallic contact and avoiding the delamination associated with conventional coatings. The company states its stacks reach approximately 90% HHV efficiency using no platinum-group metals (no iridium or platinum), and describes the electrodes as independently validated and operating in commercial AEM systems at MW scale, with third-party characterisation and electrochemical testing completed at external research laboratories.

The product line spans catalyst-coated electrodes for alkaline, AEM and adjacent electrochemistry; nanostructured PTLs on nickel and titanium substrates (including an ultra-thin platinized PTL for PEM and a Ru-Ir-free titanium PTL for electrochlorination); and electrolyser stacks in 2 kW, 20 kW and 200 kW sizes, offered as stacks alone or as complete systems, plus a 20 kW "cube" (10 kg H2/day) and a 1 MW container (500 kg H2/day). Listed prices include US$1,557 for catalyst-coated electrodes, US$621 for the platinized PTL and US$3,880 for an AEM electrolyzer cell. Green hydrogen (alkaline and AEM electrolysis) is described as the beachhead market, with the same platform positioned for five adjacent electrochemical applications: CO2 conversion and e-fuels gas-diffusion electrodes, electro-oxidation and PFAS removal, nickel plaque electrodes for Ni-H2/Ni-Cd/Ni-Zn batteries, structured hydrogenation catalyst inserts, and urea/ammonia oxidation.

Earlier company and investor communications described the technology in terms of nanostructured electrodes that increase active surface area, raising current-density output by almost 2x while cutting precious-metal loading — reported as an order-of-magnitude reduction generally, and up to 30x lower PGM loading in PEM electrolysers — and reducing energy use by around 10%, with the technology described as applicable to almost all commercially available electrolysers.

Founding story

Company accounts state SunGreenH2 began in 2020 in Singapore when Tulika Raj, a commercial leader with about 15 years in the energy sector who had scaled renewable energy companies and led project investments at renewable funds, met Dr Saeid Masudy Panah, a multidisciplinary scientist with over ten years of R&D experience in thin-film solar cells, photodiodes and transistors who had invented a series of water-splitting electrodes. They concluded that his research could be applied to electrodes for green hydrogen and founded the company on the premise that net-zero targets cannot be met without accelerating green hydrogen, since direct renewable electrification addresses only about 25% of global CO2 emissions.

Business model

SunGreenH2 describes three routes to market: direct sale of finished electrodes, PTLs and stacks; licensing of its electrode manufacturing technology and, for AEM and CO2 electrolysis, its stack designs, transferred into a licensee's existing production line with materials supply and a royalty per square metre; and toll manufacturing, in which customers supply their own catalyst material and SunGreenH2 returns finished electrodes in the specified geometry under the customer's brand. It also offers standalone validation and testing services (XRD, SEM, adhesion and full electrochemical evaluation) delivered as documented reports. Licensing is presented as the mechanism for reaching gigawatt-scale volumes without gigawatt-scale capital.

Product sales at published unit prices (e.g. US$1,557 catalyst-coated electrodes, US$621 PTL, US$3,880 AEM electrolyzer cell), technology and stack-design licensing with materials supply plus a per-square-metre royalty, toll manufacturing fees, and paid characterisation/testing services.

Traction

By August 2022 the company reported trials of its materials with leading global electrolyser OEMs, a prototype electrolyser cell under demonstration at A*STAR's Institute of Materials Research and Engineering, secured pilot projects, and commercial collaboration opportunities with Molymet and Mitsubishi Heavy Industries, with opportunities explored in Singapore, the EU, North America, Japan and India. Its current website states that electrodes operate in commercial AEM systems at MW scale, that extensive third-party testing has been completed at external research and testing laboratories, and that manufacturing capacity is already in place and operating. A third-party startup directory records total funding of $4.5M as of February 2026.

Latest developments

The current website presents the NanoFuzeX platform with claims of ~90% HHV stack efficiency, zero PGMs, MW-scale commercial AEM deployments and in-place manufacturing capacity, alongside a three-route commercial model (product sales, licensing, toll manufacturing) and an expansion of target applications into CO2 conversion/e-fuels, PFAS removal, nickel batteries, structured hydrogenation catalysts and urea/ammonia oxidation. A third-party directory entry updated 22 February 2026 lists cumulative funding of $4.5M.
