Simulated Wave Energy Hydrogen Electrolysis Performance Data

Featuring simulated performance data for a 1.25-MW proton exchange membrane electrolyzer powered by modeled wave energy converters. It includes 25-minute experimental profiles captured at 1 Hz, with variations in wave plant peak power (5 MW and 10 MW), accumulator use, and electrolyzer current ramp rates (200 and 400 amperes per second). The data is intended for planning and validating models of megawatt-scale hydrogen technologies.

Use Cases

• Validate hydrogen production models using 1-Hz hydrogen mass production data from a Coriolis flow meter under variable wave energy inputs.
• Analyze the impact of accumulator and pressure relief valve settings on system performance by comparing profiles with and without these smoothing components.
• Model electrolyzer response to variable power by training on data with different current ramp rates (200 and 400 A/s).
• Scale system performance simulations using profiles designed for four or eight 1.25-MW electrolyzer units.

Strengths

• Data is captured at a high 1-Hz frequency, providing detailed temporal resolution for dynamic analysis.
• Experiments test specific, documented system parameters including a 1.25-MW electrolyzer and simulated wave plants peaking at 5 MW and 10 MW.
• Includes controlled variations in key operational factors like accumulator use and current ramp rates for comparative study.

Limitations

• The dataset is based on simulated wave energy profiles, not real-world operational data from physical wave farms.
• The temporal coverage is limited to 25-minute experimental runs, which may not capture longer-term system behaviors or degradation.
• Data availability is restricted to specific experimental configurations (e.g., single electrolyzer stack), limiting generalizability to other system scales.
