Endua

Endua is an Australian hydrogen technology company that designs and manufactures advanced PEM (proton exchange membrane) electrolyser systems and long-duration energy storage products. Founded in 2021, the company set out to address a persistent problem in the hydrogen sector: conventional hydrogen projects were typically too large, too expensive or too complex for most organisations to adopt. Endua's answer is a suite of compact, modular, plug-and-play systems that allow industrial and commercial users to produce green hydrogen on-site, where and when it is needed, rather than relying on long-distance transport and bulk storage. The company's core product line is built around PEM electrolyser technology. Endua offers compact electrolyser units rated at 250 kW (producing roughly 4.7 kg of hydrogen per hour) as well as industrial megawatt-scale solutions of 1 MW and above (about 18.8 kg/hr). These systems are designed to be complete, all-in-one packages that include the balance of plant required to begin generating hydrogen quickly, with autonomous operation and cloud-based monitoring. Endua states that its plug-and-play design can transform installation from months into hours, and that its compact systems eliminate hydrogen transport costs and bulk storage requirements while giving customers predictable supply and transparency over carbon and energy footprints. Alongside its electrolysers, Endua produces the "power bank," an all-in-one long-duration energy storage solution. The power bank is described as delivering 100 kW of power for up to 40 hours of continuous operation, with multi-day or multi-week storage capacity of 3 MWh per container. It is positioned as a generator replacement for remote energy systems, microgrids, mining, agriculture, environmentally sensitive locations and water treatment. Endua's technology traces back to roughly 15 years of research and development in PEM electrolysis conducted by Australia's national science agency, CSIRO. Endua combined that research with its own team's expertise in electrical engineering, manufacturing, green energy and hydrogen to engineer and manufacture its product suite. The company has been supported by reputable global partners and investors including Ampol, CSIRO and Main Sequence. Endua engineers and manufactures its technology in Australia and serves both domestic and international markets. Endua targets a wide range of hydrogen use cases, including chemicals, industrial heat and boilers, food production and preparation, green steel, energy, synthetic gas and e-fuel feedstock, liquid hydrogen, and mobility across land, marine and aviation. A notable demonstration of its technology was the deployment of an Endua power bank at Archerfield Airport, which the company presented as evidence that hydrogen technology can be viable in a critical commercial setting and as a practical pathway for businesses to adopt clean energy despite immature supply chains, logistical complexity, financial constraints and regulatory hurdles.

Endua was founded in 2021 in Australia to tackle a long-standing challenge in the hydrogen industry: hydrogen projects were either too large, too expensive or too complex for many organisations to adopt. The company's founding premise was to make green hydrogen production faster, at smaller scales and with fewer barriers. The technological foundation of Endua's products comes from roughly 15 years of research and development in PEM electrolysis carried out by CSIRO, Australia's national science agency. Endua combined this research with its own team's extensive expertise in electrical engineering, manufacturing, green energy and hydrogen to engineer and manufacture a suite of technologies enabling distributed, on-site production of green hydrogen. The company has been supported by reputable global partners and investors, including Ampol, CSIRO and Main Sequence. Endua designs and manufactures its advanced PEM electrolyser technology in Australia, serving industries both locally and internationally. Its product strategy centres on compact, modular, plug-and-play systems that eliminate the need for long-distance hydrogen transportation and bulk storage, reducing associated costs and environmental impacts. The company's portfolio includes PEM electrolysers ranging from 250 kW compact units to 1 MW+ industrial solutions, electrolyser stacks from 125–250 kW up to 1–5 MW, and the "power bank" long-duration energy storage system rated at 100 kW with 3 MWh per container. A significant milestone in the company's commercialisation came with the deployment of an Endua power bank at Archerfield Airport, documented in a February 2025 company blog post. The deployment was presented as a demonstration that hydrogen technology can be viable in a critical commercial setting, and as a practical pathway for businesses to achieve clean energy despite challenges such as immature supply chains, logistical complexity, financial constraints and regulatory hurdles. Endua framed the project as helping unlock the potential of hydrogen to meet business demands, noting Australia alone has a substantial potential hydrogen investment pipeline. Endua's technology targets a broad set of use cases: chemicals, industrial heat and boilers, food production and preparation, green steel, energy, synthetic gas and e-fuel feedstock, liquid hydrogen, and mobility across land, marine and aviation. The company positions its systems as delivering large-scale plant efficiency without the massive infrastructure investment, with predictable supply, autonomous operation and cloud-based monitoring.
