Hydrogen is emerging as an important energy vector that can accelerate the path toward net-zero emissions. Given its diverse application and its potential to abate carbon emissions, it is ideally suited as an enabler to the circular carbon economy. This H2 Cost Analysis tool provides a quick, simple, and convenient analysis for electrolysis and SMR- based hydrogen production options. Users can alter values for a large set of input parameters to assess the corresponding impact on the levelized cost of hydrogen production and financial performance of the use case.
