FluviusH2 Backed by HKSTP Co-Investment Accelerator Fund in Seed Round

FluviusH2 Receives Seed Investment from HKSTP Fund

FluviusH2 Limited, a Hong Kong green-hydrogen startup also known as 江河绿氢, has raised seed funding from the HKSTP Co-Investment Accelerator Fund. The fund is the sole investor in the round.

What FluviusH2 Does

FluviusH2 develops bio-enzyme-coupled water electrolysis, an approach aimed at producing zero-carbon hydrogen at lower cost and with lower energy use than conventional methods. The company is based at Hong Kong Science Park.

Its team consists of new-energy scientists and chemical engineers, including several UK-trained doctorate holders. The team's expertise spans research and development, hydrogen system integration, and commercial partnerships.

The company targets applications across industry, transportation, and energy storage — three areas where hydrogen is frequently positioned as a decarbonization pathway.

Leadership

FluviusH2 is led by founder and CEO Duan Zehui.

The HKSTP Co-Acceleration Fund

FluviusH2 became one of the first four investees of the HK$500 million Co-Acceleration Fund managed under HKSTP (Hong Kong Science and Technology Parks Corporation). The fund's backing places the company among an initial cohort of selected startups.

Acquisition Perspective

FluviusH2 sits at the intersection of hydrogen production technology and electrolysis innovation. Its bio-enzyme-coupled water electrolysis approach targets two of the persistent challenges in green hydrogen: cost and energy consumption. If the technology performs at commercial scale, those are precisely the levers that determine whether green hydrogen can compete in industrial, transport, and storage applications.

The company's location at Hong Kong Science Park and its selection as an early investee of the HKSTP Co-Acceleration Fund give it access to an established innovation ecosystem in Hong Kong. Its team combines academic credentials — including UK-trained doctorate holders — with capabilities in system integration and commercial partnerships, a mix that matters for moving electrolysis technology from the lab toward deployment.

For acquirers and strategic partners in energy, hydrogen, and industrial technology, FluviusH2 represents an early-stage asset in the green hydrogen value chain. The company's focus on lowering the cost and energy intensity of hydrogen production addresses a market need that spans multiple end applications, from industry to transportation to energy storage.

At seed stage, with backing from the HKSTP Co-Investment Accelerator Fund, FluviusH2 is positioned to advance its bio-enzyme-coupled electrolysis technology and pursue commercial partnerships in its target markets.
