Hydrogen Electrolysis Performance from Historical Wind Profiles

1 Hz data captures hydrogen production from a 1.25-MW proton exchange membrane electrolyzer driven by a historical wind profile. The profile was derived from a five-year analysis of a single 1.5MW GE wind turbine, selecting the most variable four-hour period from December 25, 2022. This dataset provides a baseline for modeling megawatt-scale hydrogen technologies under variable renewable inputs.

Use Cases

• Model electrolyzer response to variable power input using 1 Hz hydrogen mass production and current data.
• Validate proton exchange membrane electrolyzer performance simulations against real-world 1.25-MW system data.
• Analyze the relationship between scaled wind power profiles and DC current applied to the electrolyzer stack.
• Forecast hydrogen output using time-series data of power translated to current at 1 Hz frequency.
• Assess stack aging effects by examining changes in the minimum safe operating current over time.

Strengths

• Data is captured at a high 1 Hz frequency, enabling detailed temporal analysis.
• Based on a five-year historical wind data analysis (2020-2025) from a specific 1.5MW turbine.
• Focuses on a real, megawatt-scale 1.25-MW proton exchange membrane electrolyzer system.
• Provides a calibrated translation from wind power (kilowatts) to electrolyzer current (amperes).

Limitations

• The wind profile is derived from a single turbine at one location, limiting geographical representativeness.
• Electrolyzer data corresponds to a specific, scaled four-hour test period, not continuous long-term operation.
• The actual minimum safe operating power for the electrolyzer changes over time due to stack aging.
