Hysata pioneers the world’s most efficient electrolyzer for economical green hydrogen production

Green hydrogen has become a crucial player in the worldwide pursuit of sustainable energy solutions. Produced through the electrolysis of water using sustainable energy sources, green hydrogen offers a carbon-neutral alternative to fossil fuels. Nevertheless, the path to establishing green hydrogen as a cost-effective solution has been filled with obstacles, mainly stemming from the limitations and expenses tied to conventional electrolysis methods.

Introducing Hysata, an innovative Australian start-up that is transforming the hydrogen production industry with its cutting-edge capillary-fed electrolyzer technology. This blog explores Hysata’s unique approach, its technological progress, and the potential influence on the green hydrogen economy.

The Challenge of green hydrogen production

Green hydrogen production involves the process of splitting water into hydrogen and oxygen using electricity generated from sustainable sources such as wind and solar power. Although the idea is simple, putting it into practice has proven to be more challenging. Traditional electrolyzers, which have been around since the 1800s, suffer from significant inefficiencies. Usually, these systems have an efficiency rate of approximately 75%, resulting in a significant amount of input energy being wasted as heat instead of being utilized to generate hydrogen.

Traditional electrolyzers are not only inefficient, but they also contribute to the high cost of hydrogen production and put a significant strain on renewable energy resources. In order for green hydrogen to become a practical substitute for fossil fuels, it needs to be produced in a manner that is both efficient and cost-effective. This is where Hysata’s cutting-edge technology comes into play.

Hysata’s technological breakthrough

Hysata, based in Wollongong, Australia, has created an advanced electrolyzer that has the potential to revolutionize the financial aspect of producing green hydrogen. The company’s capillary-fed electrolyzer (CFE) has an exceptional efficiency of 95%, which is significantly higher than the industry standard. This achievement is made possible by an innovative design that effectively eliminates the formation of gas bubbles, which has long been a significant cause of inefficiency in conventional electrolyzers.

The capillary-fed electrolyzer

The core innovation of Hysata’s technology lies in its capillary-fed design. Conventional electrolyzers employ a membrane to effectively separate the hydrogen and oxygen gasses generated during the process of electrolysis. Nevertheless, this membrane also generates resistance, resulting in energy inefficiencies. Hysata’s design revolutionizes the function of the membrane, utilizing it as a pathway to directly supply the electrolyte to the electrodes. This method prevents the build-up of gas bubbles, which can often clog the electrodes and decrease overall efficiency.

The separator in Hysata’s electrolyzer has a structure similar to that of a kitchen sponge when observed at the microscopic level. This structure is fully saturated with the electrolyte, which allows for optimal conductivity while effectively maintaining separation between the gasses. Hysata’s design ensures a direct contact between the electrodes and the electrolyte, resulting in reduced resistance and enhanced efficiency.

Economic and environmental impact

Hysata’s electrolyzer offers a remarkable level of efficiency, resulting in substantial cost savings for hydrogen producers. As a specialist in renewable energy, Hysata’s technology significantly lowers both operational and capital costs with an energy requirement of only 41.5 kWh per kilogram of hydrogen. This increased efficiency not only enhances the competitiveness of green hydrogen compared to fossil fuels, but also expedites the shift towards a decarbonized energy system.


One of the main challenges hindering the widespread adoption of green hydrogen is its relatively high production cost. Conventional electrolyzers typically consume approximately 52.5 kWh of energy to generate one kilogram of hydrogen, resulting in a costly and less appealing process when compared to hydrogen derived from fossil fuels. Hysata’s electrolyzer boasts an impressive 95% efficiency, consuming a mere 41.5 kWh per kilogram. This remarkable feature greatly reduces the levelized cost of hydrogen (LCOH).

With the decreased energy demand, hydrogen producers can reach their cost goals ahead of schedule. Hysata is striving to achieve a cost of less than $2 per kilogram for hydrogen production, a crucial milestone in making green hydrogen economically feasible and competitive with traditional fuels.

Commercialization and future Prospects

Hysata’s transformation from a university laboratory to a prominent figure in the green hydrogen industry showcases the power of groundbreaking technology to foster sustainable progress. The company has successfully secured significant funding and formed strategic partnerships to expand its production capabilities and introduce its technology to the market.

Funding and partnerships

Hysata has received substantial funding from prominent international investors such as bp Ventures, Templewater, and the Clean Energy Finance Corporation (CEFC). The recent investment round of $111.3 million USD will allow Hysata to increase its production capacity and continue advancing its technology. The company aims to achieve gigawatt-scale manufacturing by 2025, establishing itself as a significant player in the global electrolyzer market.

Aside from securing financial support, Hysata has established valuable alliances with prominent figures in the industry. The company’s electrolyzer technology will undergo a trial at the Stanwell Power Station in Queensland, Australia. This trial is part of a commercial demonstration project that has received support from the Australian Renewable Energy Agency (ARENA) and the Queensland Government. These trials will be instrumental in confirming the effectiveness of Hysata’s technology in practical scenarios and setting the stage for widespread implementation.

Global impact

Hysata’s technology has the potential to make a significant impact on a global scale. With a robust pipeline of nearly 40 GW of conditional orders and letters of intent from customers worldwide, Hysata is well-positioned to make a substantial impact in the global hydrogen economy. The company’s cutting-edge electrolyzer design, along with its affordability and exceptional efficiency, establishes it as a frontrunner in the shift towards sustainable hydrogen.


Hysata‘s groundbreaking capillary-fed electrolyzer is a major advancement in the pursuit of cost-effective and high-performing green hydrogen generation. With a focus on improving the performance of conventional electrolyzers and making hydrogen production more affordable, Hysata is playing a crucial role in maximizing the benefits of green hydrogen as a sustainable energy solution. With the world’s increasing focus on achieving a net-zero future, Hysata’s cutting-edge technology is set to make a significant impact in reducing carbon emissions in challenging industries and accelerating the global transition to cleaner energy sources.

The story of Hysata highlights the significance of innovation and collaboration in addressing the critical energy issues faced by our world.
