STORAGER HYP40 | PEM Electrolyser Stack | up to 104.77kW | 40 barg

STORAGER HYP40 – Modular PEM Electrolyser Stack

• The STORAGER HYP40 is a modular PEM electrolyser stack designed for industrial green hydrogen production. With an active electrode area of 475.3 cm² per cell and available configurations from 1 to 45 cells, the STORAGER HYP40 can be tailored to different hydrogen production capacities and electrical operating requirements.
• Depending on the selected cell count, the available configurations provide a hydrogen production capacity of approximately 0.44 to 19.68 Nm³/h at 100% load and a specified connected load of approximately 2.33 to 104.77 kW DC at 70 °C.
• In the listed 45-cell configuration, the STORAGER HYP40 provides a hydrogen production capacity of up to 19.68 Nm³/h at an outlet pressure of up to 40 bar(g), with a specified connected load of up to 104.77 kW DC.
• The STORAGER is one of four PEM electrolyser stack platforms developed by Hydrogen Innovation GmbH. PURIFIER, CUSTOMIZER, SUPPLIER and STORAGER provide different active cell areas for a wide range of system sizes and applications.
• Although the STORAGER HYP40 is technically available in configurations from 1 to 45 cells, the platform is particularly cost-effective for stack power requirements from approximately 40–50 kW upwards. For lower power requirements, the smaller SUPPLIER platform generally provides a more favorable price-performance ratio.
• Hydrogen Innovation GmbH supports customers in selecting the most suitable stack platform, active cell area and number of cells based on the required hydrogen production capacity, operating pressure and electrical system requirements. Our engineering team can also assist with the design and integration of the required balance-of-plant components.
• The STORAGER HYP40 builds on PEM electrolysis technology developed within HIAT gGmbH, the parent company of Hydrogen Innovation GmbH. Together, the companies draw on more than 15 years of experience in the research, development and industrialization of PEM electrolysis technology.
• The STORAGER HYP40 is made in Germany. Development and manufacturing take place in Germany, while final assembly and Factory Acceptance Testing are performed exclusively at Hydrogen Innovation GmbH’s facility in Schwerin.

Key Benefits

• Flexible stack configuration: Configurable from 1 to 45 cells to meet different hydrogen production capacities and electrical operating requirements.
• High-pressure hydrogen production: Hydrogen outlet pressure of up to 40 bar(g).
• Continuous full-load capability: The stack is designed for continuous operation at 100% rated load. The specified maximum output is not limited to short-duration peak operation and does not require time-based derating, provided the specified operating conditions and media-supply requirements are maintained.
• Scalable modular architecture: Suitable for combining multiple stacks in larger and redundant electrolyser systems.
• High hydrogen quality: Maximum oxygen content of 500 ppm in hydrogen, with an optional configuration for a maximum of 50 ppm.
• Long operating lifetime: Expected operating lifetime of more than 60,000 hours.
• Experienced engineering support: More than 15 years of PEM electrolysis expertise within Hydrogen Innovation GmbH and its parent company HIAT gGmbH.
• Made in Germany: Developed and manufactured in Germany, with final assembly and Factory Acceptance Testing performed exclusively in Schwerin.
• Safety and conformity: CE marked and designed and assessed in accordance with ISO 22734:2019.

Technical Specifications

• ¹ The specified stack-voltage and connected-load values include a design safety margin. The actual voltage and electrical power consumption of a newly delivered stack are typically significantly lower.
• ² Continuous full-load operation requires compliance with the specified operating temperature, water flow, pressure and media-quality requirements.
• ³ Following commissioning, the stack undergoes an initial conditioning phase with a temporarily elevated voltage degradation rate. The rate subsequently decreases and typically stabilizes at approximately 8–10 µV/h per cell. Actual behavior depends on operating conditions, load profile and operating cycles.

Hydrogen and Oxygen Performance

Process and Cooling Water Requirements

• ⁴ Cold start and stack-assisted warm-up are possible from a water inlet temperature of 5 °C. During warm-up, stack voltage and hydrogen production capacity are limited to protect the stack. Full rated hydrogen production capacity is typically available from approximately 45–50 °C.
• The oxygen and process/cooling-water sides share a common loop with a maximum operating pressure of 2.5 bar(g). At 100% stack load, the reference water flow is 126.7 L/min at Beginning of Life and 178.3 L/min at End of Life. During partial-load operation, the water flow may be reduced according to the thermal load, provided the temperature increase across the stack does not exceed 5 K.

Dimensions, Weight and Media Connections

• ⁵ Stack length and weight vary depending on the selected number of cells.
• The listed dimensions and weight apply to the 45-cell configuration. Stack length and weight vary according to the selected number of cells. The STORAGER is equipped with 1″ female BSPP media connections as standard. Adaptations to compression-tube fittings in commonly available sizes from 1″ downwards can be provided to meet customer-specific system requirements.

Safety and Conformity

• The STORAGER HYP40 is CE marked and has been designed and assessed in accordance with ISO 22734:2019. Each stack undergoes Factory Acceptance Testing at Hydrogen Innovation GmbH’s facility in Schwerin, Germany prior to delivery.

Typical Applications

• Industrial green hydrogen production
• Modular and scalable electrolyser systems
• Decentralized hydrogen generation
• Power-to-gas and energy-storage systems
• Research, pilot and demonstration plants
• Customer-specific system integration

Availability and Delivery

• The typical delivery time for a STORAGER HYP40 is approximately 10–12 weeks. The final delivery schedule depends on the selected cell count, connection configuration, project requirements and current production capacity and is agreed individually with the customer.
