ISO 16110-2:2010

Overview - ISO 16110-2:2010 (Hydrogen generators | Test methods for performance)

ISO 16110-2:2010 specifies standardized test methods for performance of packaged, self-contained or factory‑matched hydrogen generators that convert a fuel into a hydrogen‑rich stream. It applies to stationary hydrogen generators with capacity less than 400 m3/h (at 0 °C and 101 325 kPa). The standard defines the test boundary, measurement techniques, test plans, procedures, calculations (including efficiency) and reporting requirements to ensure repeatable, comparable performance data for systems used with fuel cells, compression/storage systems or other hydrogen users.

Key technical topics and requirements

• Scope & system boundary: Clear definition of which subsystems and energy/recovery streams are included (fuel, air/oxidant, steam, cooling, electrical inputs, hydrogen output, waste heat, etc.).
• Measurement techniques: Requirements for instruments and methods to measure electrical power, fluid flow rates, temperatures, pressures and gas composition; conformity with referenced standards is required.
• Fluid composition & heating value: Procedures for measuring or calculating composition and heating value of input fuels and output hydrogen‑containing streams (natural gas analysis referenced to ISO 6974 / ISO 6975).
• Operational states: Definitions and tests for cold state, start‑up time, standby state and steady‑state production.
• Test plan & uncertainty: Guidance on test modes, frequency, duration and uncertainty analysis to meet measurement targets.
• Safety & execution: Safe operation of generator and test equipment during testing.
• Calculations & efficiency: Methods to calculate electrical input, flow rates, fuel/steam/hydrogen energy, and overall hydrogen generator efficiency (informative annex explaining definitions).
• Reporting: Summary, detailed and full report templates and informational annexes (symbols, uncertainty guidance, fuel heating value, reference gas).

Practical applications

• Performance verification during development and factory acceptance testing.
• Comparative benchmarking of hydrogen generator products.
• Commissioning and acceptance testing for stationary hydrogen supply systems (e.g., fuel cell power plants, hydrogen fueling stations).
• Supporting certification, procurement and lifecycle energy accounting by providing consistent, auditable performance data.

Who uses this standard

• Hydrogen generator manufacturers and system integrators
• Test laboratories and certification bodies
• Fuel cell OEMs and hydrogen infrastructure operators
• R&D teams and energy auditors evaluating hydrogen production efficiency
