Description

​

The HySupply Cost Analysis Tool is a Microsoft Excel Workbook developed to model the hydrogen output and costs involved in the production of green hydrogen from solar, wind and combined solar and wind (referred to as hybrid) power plants in Australia. The tool extends beyond current state-of-the-art models, by providing the user the complete freedom to define their desired plant capacities and design a wide variety of configurations to integrate the electrolyser and the renewable power plant, which include options for a grid connected, off grid and battery connectivity. 

​

Solar and wind traces for various locations around Australia (already preloaded with additional option for the user to include their own) are used to model the operation of an electrolyser within the region to simulate and visualise hourly hydrogen generation to establish the eventual amount of hydrogen generated each year of operation. The tool also considers generally under-explored electrolyser and power plant operating factors such as variation of electrolyser efficiency with load, electrolyser/power plant efficiency degradation with operating life, conditional options to overload the electrolyser amongst many other features.

​

A subsequent cost model then establishes the capital and operating costs associated with generating the amount of hydrogen, which are then used to estimate the levelised cost of hydrogen through a discounted net present value analysis.
