We are tasked with assessing the feasibility of repurposing concrete weapons bunkers located in Umatilla, Oregon to store hydrogen gas. Hydrogen gas has been identified as an important raw material in the production of fertilizer and a potential source of fuel alternative. The scope of this project will include preliminary research on methods to encapsulate hydrogen gas in existing concrete structures with a focus on polymer-based liners and sprays. Along with a feasibility study on these methods based on their financial cost and required maintenance. Additional considerations will be made regarding the structural integrity of these chambers, their performance under pressurization, and their permeability. Deliverables for this project are as follows: projected mass of hydrogen gas able to be stored per bunker, suggested pressure to store the hydrogen gas, suggested lining material, suggested pre-storage bunker maintenance if applicable, projected cost per bunker not considering pressurization costs, and projected cost of storage per kilogram of hydrogen gas.
