“…The fundamental stages and static baseline emissions of fast pyrolysis of corn stover are illustrated in Figure 1. Aspects surrounding bio-oil as an alternative energy source for electricity generation have been studied fairly extensively (Grassi and Bridgwater, 1993;Bridgwater et al, 2002). In recent years, interest in the potential for bio-oil to be upgraded via hydro-processing to bio-gasoline has grown Hsu, 2011).…”

A partial solution to problems associated with anthropogenic greenhouse gas (GHG) emissions could be the development and deployment of carbon-negative technologies, i.e., producing energy while reducing atmospheric carbon dioxide levels. Biofuels have been considered a possibility but have faced limitations due to competition with food production and GHG emissions through indirect land-use change (ILUC). In this article, we show how emissions from ILUC can potentially be reduced by producing food and bioenergy from biochar amended soils. The possibility of yield improvements from biochar would reduce the land requirement for crop production and thus, lead to a reduction in emissions from ILUC. In our application, biochar and bio-oil are produced via fast pyrolysis of corn stover. Bio-oil is subsequently upgraded into a fuel suitable for use in internal combustion engines. Applying the U.S. regulatory method used to determine biofuel life cycle emissions, our results show that a biochar-induced yield improvement in the U.S. Midwest ranging from 1% to 8% above trend can lead to an ILUC credit between 1.65 and 14.79 t CO 2 -equivalent ha −1 year −1 when future emissions are assessed over the next 30 years. The model is generalizable to other feedstocks and locations and illustrates the relationship between biochar and crop production.

“…Biomass conversion technologies have garnered more attention in recent years. The rationales of biomass utilization include long-term energy security, environmental benefits by recycling wastes and residues, reduction of greenhouse emissions, and economic development of rural areas . Wood and wood wastes are the most abundant biomass resource, comprising almost 64% of the energy that derives from biomass .…”

In recent years, chemical looping has evolved into a promising technique for carbonaceous fuel conversion. The chemical looping technology using biomass material as feedstock could provide a process that is environmentally attractive and sustainable. The focus of this study is to examine the kinetics of biomass decomposition and to evaluate the feasibility of using biomass as a renewable source for chemical looping processes. A series of thermogravimetric experiments were carried out under inert and reactive gas environments to investigate the kinetics of the devolatilization and gasification stages of biomass decomposition. Since tar derived from biomass pyrolysis is a major concern for many biomass conversion techniques, the cracking of biomass derived light tar using iron oxide-based composites was also investigated in a fixed bed reactor. Furthermore, a bench scale moving bed reactor was used to study the feasibility of biomass chemical looping in both cocurrent and countercurrent gas–solid contact modes.

“…Energy Conversion Factor of Biomass dedicated to energy production; and urban waste. Given the numerous applications of biomass and the variety of sources, it is not surprising that wide arrays of biomass conversion technologies are under development and commercialized [5][6][7][8]. However, the cost of collecting enough biomass to be used in commercial biomass energy conversion plants is remained as big hurdle for biomass energy conversion.…”

Biomass is recognized as one of important renewable energy sources because it can be converted and used as solid, gaseous and liquid forms. Also, biomass is one of promising ways to solve the depletion of fossil fuels and global warming problems. The information about local biomass energy potentials and space energy densities can be powerfully utilized to determine the scale of biomass energy conversion plant and to analyze economic effects. The latest data on domestic biomass resources, such as agricultural, forestry, livestock and urban wastes, were collected from various government organizations and institutes and were analyzed to calculate biomass energy potential and space energy density. As local areas in South Korea to collect biomass resources increased, energy potentials increased, but space energy densities of total biomass decreased.
