NIHPA (Nuclear Integrated Hydorgen Production Analysis) is an Excel-based discount cash flow calculator for hydrogen production by integrating light water reactors with high temperature steam electrolysis (LWR-HTSE) or low temperature electrolysis (LWR-LTE).

The tool incorporates the following features:

• Discounted cash flow and levelized cost of hydrogen (LCOH) analysis
• Sensitivity analysis with respect to select financial performance metrics with output ‘tornado’ charts
• Profitability analysis represented by heat maps using the two most sensitive parameters
• Electricity versus hydrogen production preference analysis by comparing change in net present value (∆NPV) between LWR-HTSE (or LWR-LTE) and business-as-usual electricity production to the grid
• Competitiveness analysis by comparing the calculated LCOH for LWR-HTSE (or LWR-LTE) with that of steam methane reforming, which is the conventional process to produce hydrogen
