Green Hydrogen Generation and Storage System 

The Green Hydrogen Generation and Storage System by Ecosense is a modular, reconfigurable educational and research-grade platform that replicates the complete hydrogen value chain—from renewable power harvesting to hydrogen generation and safe storage. Designed for engineering institutions, R&D labs, and clean energy centers, this system serves as a real-world replica of decentralized hydrogen production hubs. It enables comparative experimentation with leading electrolyzer technologies (PEM, AEM, Alkaline) and supports multiple input sources including photovoltaic arrays, PV emulators, and AC grid supply. With the flexibility to switch technologies and test variables under controlled lab conditions, this platform prepares students and researchers to design, operate, and optimize hydrogen infrastructure in alignment with future energy systems. 

Key Features

  • Choice of Electrolyzer Type: Configure the system with any one of the following electrolyzers:PEM (Proton Exchange Membrane); AEM (Anion Exchange Membrane); Alkaline Electrolyzer.  Each variant includes suitable purification, control, and safety features.
  • Multiple Power Source Options: Users can power the electrolyzer using: A real Solar PV Array or A Solar PV Simulator or standard AC grid electricity.This flexibility allows year-round experimentation in both lab and field environments.
  • Hydrogen Leak Detection & Safety System: Integrated leak detectors, solenoid valves, and NRVs provide real-time safety with auto-shutdown capability.
  • Real-Time Monitoring and Control: View live parameters such as voltage, current, hydrogen pressure, flow rate, and power output—ideal for student-led experiments and lab reporting.
  • Efficient Electrolysis and Hydrogen Production: Water electrolysis is driven by the selected power input and electrolyzer. The system includes flow-regulated water pumps, safety interlocks, and real-time monitoring of production parameters such as voltage, current, temperature, and gas output.
  • Safe Drying and High-Pressure Storage: Produced hydrogen passes through a drying column and is stored in high-pressure steel cylinders. The storage system includes check valves, pressure relief, regulators, and a desiccant system to ensure safety and long-term usability.
  • Integrated Control and Visualization Software: A LabVIEW-based control panel displays real-time sensor data and system performance. Users can define test profiles, adjust operating conditions, and export performance data for further analysis or publication.

How the Green Hydrogen Generation and Storage System Works

  • Electrical power from a renewable source or regulated DC supply is fed to the electrolyzer stack through an integrated power conditioning unit.
  • Purified and de-ionized water is supplied to the electrolyzer using a controlled pumping system to ensure consistent flow and pressure.
  • Inside the electrolyzer (PEM, Alkaline, or AEM), water molecules are split into hydrogen and oxygen through an electrochemical reaction.
  • Oxygen is safely vented or collected separately, while hydrogen is routed through gas–liquid separators and drying units to remove moisture.
  • The dry hydrogen passes through pressure regulation and flow-measurement stages for real-time monitoring and performance analysis.
  • Hydrogen is then stored in certified storage cylinders or tanks at controlled pressure levels.
  • Integrated safety systems—including pressure relief valves, hydrogen sensors, and emergency shutdowns—ensure safe operation at all stages.
  • Data acquisition software logs voltage, current, flow rate, pressure, and efficiency parameters for analysis and experimentation.
