Abstract:

Hydrogen has the potential to be a sustainable alternative to the fossil fuels currently used in the transportation sector. The aim of our study is to appoint that producing hydrogen from biomass can be considered a green technology. There are three options for producing hydrogen from biomass. Our efforts must be focused on maximizing the reforming and shift conversions along with maximum economical recovery of hydrogen from the PSA. This work demonstrates that hydrogen can be produced economically from biomass. The pyrolysis-based technology, in particular, because its coproduct opportunities, has the most favorable economics.

I. Introduction

In the last 10 years, the defining issues with respect to H2 economics have changed dramatically. Reducing the demand on fossil resources remains a significant concern for many nations. Renewable-based processes like solar or wind-driven electrolysis and photobiological water splitting hold great promise for clean hydrogen production; however, advances must still be made before these technologies can be economically competitive. For the near- and mid-term, generating hydrogen from biomass may be the more practical and viable, renewable and potentially carbon-neutral (or even carbon-negative in conjunction with sequestration) option [1]. In 2004, the International Energy Agency's (IEA) Program on the Production and Utilization of Hydrogen launched its new Task 16, Hydrogen from Carbon-Containing Materials, to bring together international experts to investigate some of these near- and mid-term options for producing hydrogen with reduced environmental impacts. In addition to large-scale fossil-based production with carbon sequestration and production from biomass, small-scale reforming for distributed generation is included in the activity [2]. The wide range of options for sources, converters and applications shown in Fig. 1, though not exhaustive, illustrates the flexibility of hydrogen and fuel cell energy systems.
