When sourcing electrolysis technology for hydrogen (H₂) production, several critical pitfalls can impact project success, particularly concerning quality and intellectual property (IP). Below is a structured overview of common pitfalls and how to navigate them, with a focus on ensuring high-quality systems and protecting IP rights.
1. Quality-Related Pitfalls in Sourcing Electrolysis Systems
A. Overlooking Technology-Specific Performance Metrics
- Pitfall: Assuming all electrolyzers (e.g., PEM, Alkaline, SOEC) perform similarly without assessing real-world efficiency, durability, and response dynamics.
- Impact: Poor H₂ yield, higher OPEX due to inefficiency, or system failure under variable loads (e.g., renewable integration).
- Mitigation:
- Demand validated performance data under relevant operating conditions (load range, start-stop cycles, temperature).
- Require third-party testing reports (e.g., NREL, TÜV, DNV).
- Include performance guarantees in contracts (e.g., H₂ output, specific energy consumption in kWh/kg H₂).
B. Inadequate Assessment of Component Quality
- Pitfall: Focusing only on stack performance while neglecting balance-of-plant (BoP) components (e.g., compressors, dryers, power electronics).
- Impact: System downtime, safety risks, or suboptimal integration.
- Mitigation:
- Conduct full-system audits, including BoP.
- Verify material certifications (e.g., corrosion-resistant materials in contact with KOH or humid H₂).
- Require lifecycle testing data (e.g., >60,000 hours for industrial PEM systems).
C. Underestimating Long-Term Degradation
- Pitfall: Accepting initial performance without degradation rate analysis.
- Impact: Rapid decline in H₂ output or efficiency over time; unexpected maintenance costs.
- Mitigation:
- Require degradation data (e.g., <0.5–1% per 1,000 hours for PEM).
- Include warranty clauses tied to performance decay.
- Prefer suppliers with field-proven installations.
D. Ignoring Certification and Compliance
- Pitfall: Procuring systems without proper safety and quality certifications.
- Impact: Regulatory non-compliance, insurance issues, safety hazards.
- Mitigation:
- Ensure compliance with ISO 22734, IEC 62282, ASME BPVC, and local codes.
- Verify ATEX/IECEx certification if used in hazardous areas.
2. Intellectual Property (IP)-Related Pitfalls
A. Unclear IP Ownership in Custom or Co-Developed Systems
- Pitfall: Collaborating on electrolyzer design or integration without clear IP agreements.
- Impact: Disputes over ownership, inability to scale or modify the system, or third-party infringement claims.
- Mitigation:
- Define IP ownership upfront in contracts (e.g., background vs. foreground IP).
- Use joint development agreements (JDAs) with clear clauses:
- Who owns improvements?
- Can the buyer use the design elsewhere?
- Are there licensing rights?
B. Hidden IP in Proprietary Components
- Pitfall: Using electrolyzers with black-box components (e.g., catalysts, membranes) where IP is tightly controlled.
- Impact: Vendor lock-in, inability to service or replace parts independently, cost escalation.
- Mitigation:
- Require technology transparency for key components.
- Negotiate right-to-repair or spare parts licensing.
- Evaluate open-design or modular systems where feasible.
C. Infringement Risks from Supplier
- Pitfall: Sourcing from a vendor whose technology infringes third-party patents.
- Impact: Legal liability, project delays, or forced system redesign.
- Mitigation:
- Require IP indemnification clauses in procurement contracts.
- Conduct freedom-to-operate (FTO) analysis for critical components (e.g., PEM catalysts, bipolar plates).
- Prefer suppliers with strong patent portfolios and transparent IP strategies.
D. Export Control and Geopolitical IP Risks
- Pitfall: Sourcing from jurisdictions with export restrictions or weak IP enforcement.
- Impact: Supply chain disruption, reverse engineering, or loss of proprietary integration know-how.
- Mitigation:
- Assess geopolitical risks (e.g., rare materials, dual-use tech).
- Include confidentiality and non-disclosure agreements (NDAs).
- Consider onshoring or local assembly to retain control.
Best Practices Summary (H₂-Focused)
| Area | Best Practice |
|——|—————|
| Quality | Demand real-world performance data, third-party validation, and lifecycle guarantees. |
| Technology Fit | Match electrolyzer type (PEM, Alkaline, etc.) to H₂ use case (e.g., PEM for dynamic operation). |
| IP Clarity | Define ownership, licensing, and indemnification in contracts. |
| Supply Chain | Audit supplier IP position and component sourcing. |
| Compliance | Ensure adherence to H₂ safety and quality standards (ISO, IEC). |
Conclusion
Sourcing electrolysis systems for H₂ production requires balancing technical performance, long-term reliability, and IP security. Avoiding these pitfalls ensures not only a high-quality hydrogen output but also protects your organization from legal, operational, and financial risks. Always conduct due diligence, involve technical and legal experts early, and prioritize transparency with suppliers.
