Regulatory hurdles significantly hinder the adoption of molten salt energy storage (MSTS) technology across multiple dimensions:
1. Lack of Standardized Design and Safety Codes
Molten salt systems face challenges due to absent design codes, leading to inconsistencies in safety and efficiency. Current frameworks for thermal storage tanks lack clarity, increasing risks of operational failures and complicating regulatory approval processes.
2. Material and Operational Qualification
Material compatibility remains a critical issue, as high temperatures, radiation, and corrosion demand specialized alloys and cladding, which require nuclear-grade qualification. Additionally, instrumentation challenges—such as radiation-resistant sensors and leak-proof components—lack proven solutions, delaying system validation.
3. Policy and Compensation Uncertainty
Molten salt grid storage struggles with unclear revenue models, as policymakers have yet to establish standardized compensation frameworks akin to FERC Orders 841/2222 (which apply to battery storage). Without defined tariffs or tax incentives for thermal storage, investment lags.
4. Prototyping and Validation Gaps
Testing requirements for novel designs often involve non-prototypical experiments, which regulators may view as insufficient without extensive validation. This raises costs and prolongs licensing timelines, particularly for integrated renewable energy systems.
5. Regulatory Focus on Established Technologies
Existing regulations prioritize electrical storage (e.g., batteries), leaving thermal storage like MSTS underdeveloped in policy frameworks. This imbalance slows R&D funding and pilot project approvals.
Key Regulatory Challenges
| Area | Impact | Source |
|---|---|---|
| Design Codes | Inconsistent safety standards | |
| Material Standards | High costs for qualified nuclear materials | |
| Revenue Models | Unclear monetization pathways | |
| Testing Protocols | Prototyping delays |
Addressing these hurdles requires harmonizing safety codes, accelerating material certifications, and integrating molten salt storage into grid compensation mechanisms.
