This investigation performs a cost-benefit analysis with economic incentives concepts
(opportunity cost and profit index), discounted indices and adjustment techniques (twotier
learning curve and cost-capacity scaling methods) to support comprehensive financial
decisions about investment on biohydrogen plant. A life-cycle assessment is utilized to
construct four scales of the production of commercialization, which are the bench/laboratory
scale, pilot scale, demonstration scale, and commercial scale, to evaluate entire
economic feasibility.
The results reveal that the levelized cost of energy (LCOE) of biohydrogen will be
approximately USD 2 to 3/kg. All financial indices reveal biohydrogen is economically
feasible of investment and will be commercialized successfully before the timelines in
many official reports. Results reveal decision-making criteria should include the economic
incentives. LCOE of biohydrogen is less sensitive
