Shengshui Tech Cuts Green Hydrogen Costs with New Tech

A Chinese startup is making significant strides in reducing the cost of green hydrogen production, a critical step towards widespread adoption of this clean energy source. Shengshui Technology, a Hefei-based firm established in 2019, has successfully developed proprietary technologies for key components used in water electrolysis, aiming to dismantle cost barriers that have hindered the scaling of hydrogen fuel.

The company recently secured over 100 million yuan (approximately $12 million USD) in a Series A funding round. This investment was led by NIO Capital, with participation from Lenovo Capital, Zhongan Capital, and Hefei Innovation Investment. The capital infusion is earmarked for expanding production capacity to meet growing demand and constructing new manufacturing facilities.

Shengshui Technology focuses on developing and manufacturing essential materials for Proton Exchange Membrane (PEM) and Anion Exchange Membrane (AEM) water electrolyzers, including catalysts, proton exchange membranes, and membrane electrode assemblies (MEAs). Their strategy hinges on domestic innovation to drive down costs, making green hydrogen a more economically viable alternative to traditional, carbon-intensive hydrogen production methods.

Dr. Wang Xinlei, the founder, highlighted China's position as the world's largest hydrogen consumer, with the majority currently derived from coal. This "grey hydrogen" production is a major source of CO2 emissions. Green hydrogen, produced via electrolysis using renewable energy, offers a path to decarbonization. A significant portion of PEM electrolyzer costs is attributed to the MEA. Shengshui Technology has tackled this by developing ultra-thin MEAs, pushing towards 25-micrometer thickness from the current 50-micrometer standard. Their innovative "hydrogen blocking layer" technology effectively prevents hydrogen permeation, maintaining high current efficiency (over 97%) and stability even under pressure, while significantly reducing the need for expensive iridium in their catalysts.

These technological advancements have led to a dramatic cost reduction. The initial cost for a 1-megawatt PEM hydrogen production system, which stood at approximately 10 million yuan, has been reduced to around 1.177 million yuan (about $270,000 USD) with their 50-micrometer MEA. Projections suggest that with the 25-micrometer MEA, this cost could fall further to approximately 700,000 yuan (about $160,000 USD). Furthermore, the company has developed proprietary recycling techniques for precious metals, maintaining a high residual value of 40-45% for PEM electrolyzers, contributing to a lower total cost of ownership.

With production facilities in Hefei and Shanghai capable of supporting gigawatt-scale projects, Shengshui Technology has already shipped over 40,000 MEAs and anticipates its revenue to approach 100 million yuan (around $12 million USD) in 2025. The company projects a doubling of orders annually for the next two years and plans to launch several tens of megawatt-scale green hydrogen production plants in collaboration with clients by 2026. An international business center in Singapore is also operational, signaling an aggressive push into global markets.
