Generally, hydrogen is produced from renewable and non-renewable energy sources. However, production from non-renewable sources presently dominates the market due to intermittency and fluctuations inherent in renewable sources. Currently, over 95 % of H 2 production is from fossil fuels (i.e., grey H 2) via steam methane …
