Table 3: Hydrogen production cost assumptions

Production costs of hydrogen could be lower still in regions that utilize negatively priced electricity. Electrolyzer costs are based on costs to manufacture the units with overhead and profit levels associated with mature industries, not retail costs of electrolyzers at present which include significant costs for development, tooling, and other business startup costs. Production costs do not include costs associated with liquefaction, which are discussed in more detail below.
