  • This study has investigated the life cycle of three biomass feedstocks including forest residue, agricultural residue, and whole forest for biohydrogen and biopower production in Alberta. Three technologies are studied for biohydrogen production; these include the Battelle Columbus Laboratory gasifier, the Gas Technology Institute gasifier, and fast pyrolysis. The life cycle greenhouse gas emissions for nine biohydrogen pathways lie in the range of 1.20–8.1 kg CO2eq/kg H2. Biomass feedstocks in various forms (chip, bale, pellet, and torrefied pellet) are analyzed for direct and parallel co-firing technology. Biomass can be co-fired with coal in the scale of 7.53−20.45%, depending on the types of feedstocks and densification technologies. The life cycle greenhouse gas emissions for nine biopower pathways lie in the range of 957−1091 kgCO2eq/MWh. This study also analyzes the life cycle acid rain and ground level ozone precursor emissions, and evaluates net energy ratio for various biohydrogen and biopower pathways.
