Project Description

Type of Project: Analysis
Category: Hydrogen Fuel Pathways
Objectives: Conduct a boundary analysis of hydrogen production by fermentation of glucose or other carbohydrates; Determine the energy and materials balances and order-of-magnitude economics of hydrogen production by fermentation.
Technologies Considered: Fermentation unit; raw gas compressor; pressure swing adsorption (PSA); cell recovery unit; glucose
Inputs:
  • Description: Hydrogen production rate
  • Units: MMSCFD
  • Supporting Information: At 435 psig
  • Description: Cost of glucose; costs of steam and electricity
Methodology/Approach: Discounted cash flow analysis
Models Used: Aspen Plus 10.2
Data Used/Contributing Research:
  • 2002 NREL design case for bioethanol production
Outputs: Capital cost projection for 50 MMSCFD hydrogen production by fermentation, hydrogen sales price required for a 10% after tax real internal rate of return
Sensitivities Studied: Effect of hydrogen yield and the cost of glucose on the feedstock cost; effect of variations in fixed capital on the required hydrogen price; effect of glucose concentration on required hydrogen price; effect of variations in the required internal rate of return on required hydrogen price
