This document contains a pre-feasibility economic analysis for a proposed green hydrogen plant project from renewable energy powered electrolysis. It includes inputs and assumptions for project costs, financing structure, electrolyzer system specifications, production estimates, and operating expenditures. Key details include a 1000 MWe electrolyzer plant using alkaline electrolyzer technology, targeting commercial operation in 2025 with a 30-year analysis period. Capital costs and financing during an 18-month construction phase are modeled on a monthly basis.
