Abstract
- Hydrogen from renewable energy is considered a promising alternative to traditional petroleum-based transportation fuels. Potato steam peels can be used as feedstock to produce hydrogen through fermentation processes. Life cycle assessment is used as an analytical tool to evaluate the main environmental benefits and burdens of using potato steam peals to produce hydrogen rather than to feed animals. Inventory data are derived from the literature and ecoinvent. Impacts are evaluated using IMPACT 2002+. The results show that producing hydrogen from potato steam peels offers clear advantages over a direct use of peels to feed animals. A factor of two to three is observed in the reduction of greenhouse gas emissions, in the savings of non-renewable resources and in the reduction of human health impacts. The two-stage bioreactor is observed to consume around 25 MJ and to emit between 1000 and 1500 g of CO 2 per kilogram of hydrogen produced.
