Field Test Plan for Underground Hydrogen Storage Demonstration in a Porous Reservoir SHASTA: Subsurface Hydrogen Assessment, Storage, and Technology Acceleration Project

Summary

This document, SAND2024-11124R, outlines a field test plan for the Subsurface Hydrogen Assessment, Storage, and Technology Acceleration (SHASTA) Project, aiming to demonstrate underground hydrogen storage (UHS) in a porous media reservoir in the United States. The core challenge is to prove the safety and feasibility of UHS in porous media, which currently accounts for 90% of U.S. natural gas storage sites, compared to the 10% represented by salt caverns where hydrogen storage has already been proven. The approach involves a 4-year project plan, including a 2-year hydrogen injection-production cycle, targeting a depleted natural gas sandstone reservoir. Key parameters for the demonstration include storing approximately 2 BCF of hydrogen over 6 months at a rate of 20-100 MCF/day and operating at a pressure of around 1200 psi. The plan emphasizes following API best practices (API RP 1171) for natural gas storage, adapted for hydrogen, and includes extensive risk analysis, well design, and environmental monitoring.
