PEM electrolyser systems for industrial hydrogen production
The EZ-400 and EZ-2000 are fully integrated, containerised hydrogen production systems for industrial-scale deployment. Available in two sizes—400 kg/day and 2,000 kg/day—these systems deliver high-efficiency hydrogen production with minimal site integration requirements. Designed for organisations scaling hydrogen production from demonstration to commercial deployment, fleet refuelling operations, and industrial hydrogen supply.
Endua brings deployment expertise and technical partnership. We understand real-world hydrogen systems and help accelerate time-to-market across Asia Pacific markets.
5–100% turndown enables seamless renewable energy integration. Capture off-peak grid energy, track wind and solar variability, and optimise around peak pricing.
55.1 kWh/kg system efficiency delivers superior performance against conventional alkaline systems. Better energy economics mean lower operating costs at every production scale.

Frequently asked questions
Technical questions about the EZ-400 and EZ-2000 electrolysers
-
The EZ-400 and EZ-2000 use identical PEM electrolyser stack technology and deliver the same efficiency and performance characteristics. The difference is production capacity. The EZ-400 produces 400 kg/day of hydrogen; the EZ-2000 produces 2,000 kg/day. Both are containerised, modular systems suitable for on-site deployment. Choose based on your hydrogen demand and site constraints.
-
Yes. Both systems are modular. You can deploy a single EZ-400 and add additional units as hydrogen demand grows. The systems integrate seamlessly—you're adding capacity, not replacing infrastructure.
-
Both systems deliver hydrogen at 30 bar. This pressure significantly reduces downstream compression requirements compared to low-pressure or atmospheric PEM or alkaline systems. For industrial supply, it reduces compressor stages and parasitic losses. The economic benefit compounds over the system's operating life.
-
The EZ-400 and EZ-2000 accept potable water per ASTM D1193 Type I. Both systems include onboard water purification to handle modest conductivity variations typical of municipal supplies. For challenging water sources, you may need additional polishing stages in your water treatment circuit, but this is application-specific. Our team will assess your water source during the design phase.
-
Yes. Both systems operate across a 5–100% turndown range. Load response is linear—current scales proportionally with input power, making control straightforward for operators and automation systems. This flexibility is particularly valuable for renewable energy integration and managing variable electricity pricing.
-
Both the EZ-400 and EZ-2000 are containerised and modular. They can be transported and redeployed to a new site with minimal civil works. Connection points are standardised (power, water, hydrogen outlet), so site preparation is straightforward.
-
Both systems are engineered to meet AS 22734:2020 (hydrogen production by electrolysis), AS/NZS 1200:2015 (pressure equipment), AS/NZS 3000:2018 (electrical equipment), and AS/NZS 60079-14:2024 (hazardous area equipment). Systems arrive pre-certified and ready for deployment.
-
Installation and commissioning timelines depend on site preparation, electrical infrastructure, and water treatment requirements. Typical deployment ranges from 4–12 weeks from site selection to first hydrogen production. Our team will provide a detailed project timeline during the design phase.
-
Yes. The 5–100% turndown range enables seamless renewable energy integration. The system tracks solar and wind output, captures off-peak grid energy, and optimises around peak pricing periods. Load response is straightforward for automation systems and operators.
