For hydrogen to become part of everyday life, clean hydrogen must first be economically viable.
We lower clean hydrogen production costs to expand its use.One of the biggest barriers to clean hydrogen deployment is production cost. HydroXpand cannot set electricity prices, but we can improve stack performance, durability, manufacturing cost and production capacity.
Improving only one metric does not lower the real cost of hydrogen. Since our founding, we have advanced all four within the same product and manufacturing process.
Higher performance and durability, lower stack manufacturing cost, and greater production capacity.
As stack performance improved, we progressively raised rated current density while maintaining the target efficiency range.
Representative stack performance at the same current density, temperature and KOH concentration
We extend continuous operation while reducing the rate of cell-voltage rise, improving stable production time and stack replacement intervals.
Representative HydroXpand stack tests at each stage. Operating conditions may vary by development stage.
We are lowering estimated stack manufacturing cost through coordinated improvements in materials, component design and assembly.
Estimated stack manufacturing cost converted at KRW 1,350 per USD. BoP and system costs are excluded.
We expand production space, staffing and standard processes to increase annual HXS-2 production capacity.
Planned HXS-2 capacity based on 10 production staff, 250 working days per year and one shift
HydroXpand does not treat these metrics in isolation. We design and manufacture electrodes, catalysts, stacks and systems so performance, durability, manufacturing cost and production capacity improve together within the same products and processes.
Explore our technologyThe three founders met in a hydrogen lab at KAIST and completed master's and doctoral degrees in Chemical and Biomolecular Engineering. Together, they published more than ten hydrogen papers in journals ranked in the top 1% by JCR. HydroXpand was founded in December 2023.
We started the company to carry laboratory performance into real products and customer sites. More than 50 customers in 12 countries now use our electrodes and stacks, including large companies, universities, research institutes and distributors.
Technical honesty is our most important principle. When something falls short, we do not hide it. We explain how we plan to address it and when. That is also why every performance figure on this site includes its test conditions.
When something falls short, we do not hide it. We clearly share how we plan to address it and when.

Issued a manufacturer's EU declaration of conformity (DoC) for the 2 kW HXB-V1 system and applied the CE marking. Trademark classes 35 and 37 were registered the same month.
Launched the 2 kW AEM system HXB-V1 and the HXS-2 stack. Selected the same month as a deep-tech startup in D.Camp Batch 6.
First place among 7,377 teams at Korea's largest startup competition, run jointly by ten government ministries. Together with the Chung Ju-yung prize two months earlier, this completed a sweep of Korea's two biggest startup competitions.
Started at the KAIST Munji campus in Daejeon.
Top prize in the climate tech track at Korea's largest private-sector startup competition, run by the Asan Nanum Foundation.
Korea Investment Accelerator, Company K Partners and IBK Capital joined as new shareholders.
Chosen as a clean tech startup.
Relocated electrode, stack and system manufacturing and testing from Daejeon to Dongtan, Hwaseong.
Combining our AEM stack technology with their system manufacturing capability.
The engineers who design and build our stacks also service them, so customers receive technical support from the team that made the product.
