Subsurface Salt Cavern Hydrogen Storage Model

Underwrite 500,000 m³ solution-mined deep salt caverns storing 10,000 tonnes of pure compressed hydrogen at 200 bar with nitrogen cushion gas optimization (delivering 300 GWh of seasonal multi-month energy resilience to power grids). Model hydrogen storage tolling tariffs ($0.45/kg stored/mo), and 30-yr IRR.
