Abstract:
As a part of our green hydrogen initiative, the techno-economic feasibility of green hydrogen production via steam reforming of bioethanol (ESR) for forecourt application was evaluated. This was compared with the conventional steam methane reforming (SMR) process. Various techno-economic parameters such as capital cost of the forecourt unit, ethanol price, carbon tax, and natural gas price were evaluated. This techno-economic analysis for green hydrogen production clearly shows that ethanol price had the largest impact on the cost of hydrogen, which was about a sixth higher than that produced via SMR. While further process improvements may lead to some marginal reduction in capital costs the ethanol price clearly dictates the cost of hydrogen. Fuel ethanol enjoys around 51-cents/gallon subsidy in the United States and this factor should be considered while assessing the future costs if the subsidies were withdrawn. Thus the combined effect of various factors such as reduction in ethanol price, subsidies, carbon emission tax, and increased natural gas price will play an important role in making this option of green hydrogen from ethanol competitive with SMR hydrogen costs.
