Challenge

As wind energy projects expand in Newfoundland and Labrador, developers anticipate grid limitations during periods of low or no wind. This creates a need for innovative long-duration energy storage solutions to ensure reliable supply while maximizing the value of the province’s diverse onshore wind resources.

Strategy

Triple Point Resources Ltd. (TPR) explored the potential of leveraging the Fischells Salt Dome as a storage hub for compressed air, hydrogen, or a hybrid of both. The project was designed to evaluate these storage pathways within an energy systems optimization framework to determine the most effective and scalable solution.

Action

Angler Solutions contributed to Stage 0 of the project by:

• Developing an energy systems optimization model to assess integration of long-duration storage with onshore wind
• Screening storage concepts (compressed air, hydrogen, hybrid) across multiple scales and configurations
• Creating block flow diagrams of the storage processes to visualize technical pathways and integration options
• Conducting a techno-economic assessment, including Levelized Cost of Storage (LCOS) analysis
• Providing oversight and technical input during the systems impact study

Outcome

Angler’s Stage 0 work delineated a clear value proposition for TPR, providing forward-looking insights into the technical and economic feasibility of LDES at the Fischells Salt Dome. The analysis positioned TPR to play a potential role in Newfoundland and Labrador’s growing renewable energy sector and highlighted the opportunity for salt-cavern storage to shape the province’s future energy system.
