Heating Systems

Heat produced from woody biomass accounts for a significant portion of renewable energy in the United States. Economic and federal policy factors driving institutional adoption of woody biomass heating systems have been identified and examined in previous studies, as have the effects of state policies in support of biomass heating. However, plans for a number of mid- to large-scale biomass facilities have been abandoned after being proposed in communities with many of the factors and policies considered favorable to the adoption of such systems. In many of these cases, opponents cited potential negative impacts on local air quality, despite being generally in favor of renewable energy. This study employed a zero inflated negative binomial (ZINB) statistical model to determine if state policies, air quality, and local attitudes toward renewable energy have a significant effect on the adoption and retention of distributed-scale biomass combustion systems used for institutional heating. State policy appears to have a negligible effect, while the influences of historic and current air pollution and local emissions appear insignificant. However, local attitudes in favor of renewable energy are associated with the adoption and retention of distributed-scale woody biomass heating systems. This is an indication of the importance of local support in determining the fate of future biomass energy projects.

Significant Attention

Community renewable energy projects have captured significant attention due to their potential to tackle climate change by socially and economically empowering local societies. Recently, however, various difficulties in the continuity of such projects over extended periods of time have been reported. As a case study, this article explores a woody biomass project, planned and put into practice by local people, which has lasted for over 10 years. The article first examines the process of collective decision-making among members who have diverse motivations. It then focuses on how the project objectives have been interpreted by individual members, paying particular attention to each member’s practice. The article shows that decisions related to the project were based on the diverse and constant social interactions between members, which focused on their collaboration rather than overall quantitative goals. I argue, both theoretically and empirically, that this vagueness of the overall goals has enabled the project’s continuity. Based on their own practices, it has allowed each project member to interpret the project and to gain a sense of its success. Diversity of practices within a project leads to plural sets of values, which bring sustainability to a project running in an uncertain context.

Development of renewable energy production is one of the main directions of decarbonizing the Ukraine’s energy sector as well as the forestry sector. Increase in woody biomass utilization efficiency at producing energy, alongside with securing the proper level of technological processes and technical equipment, also requires a reliable information support toolbox that would facilitate managerial decisions. An important constituent of this toolbox is represented by the regional assessments of energy function of forest plant communities. The information basis of the research is formed by the information from the industrial database of IA “Ukrderzhlisproekt”, which contains the detailed biometric characteristics of the stands in the studied region, as well as by a system of mathematical models for quantitative assessment of foersts’ live biomass and dead organic matter. As a result, the quantitative values of the total energy content in live biomass and daed organic matter of Zhytomyr Polissia’s forests were determined. The total amount of energy accumulated in vegetal biomass of the region's forests is 3035.7 PJ, which corresponds to 100.2 million tons of conventional fuel. At the same time, the share of the total energy content in dead organic matter is 11.1 %. The structure of energy content in vegetal biomass in the region is dominated by pine stands, which accumulate more than 60 % of the energy of forests of Zhytomyr region, including 70.8 % - in live biomass of tree trunks. More than 40 % of energy is accumulated in vegetal biomass of stands of I site index class, which mainly grow in fairly infertile forest growth conditions. In the general structure of energy content in dead organic matter (336.2 PJ) more than 60 % belongs to forest litter (212.8 PJ which is not considered a source of renewable energy), standing dead trees 12.3 % (41.3 PJ), dry branches – 17.8 % (close to 60 PJ). The results obtained in the course of the research will serve as an information background for the formation of a strategy for development of forest bioenergy in Zhytomyr region.

Cellulosic Feedstock

Biomass has attracted attention as a source of renewable energy. It is available in different forms such as lignocellulosic stalks of herbaceous and woody biomass. These forms of biomass should be prepared to go through bioconversion process or biofuel production. One of the major unit operations for preparation is size reduction, which increases the surface area available and breaks the structure of biomass. Size reduction is energy intensive and an expensive step of feedstock preparation. The characteristics of ground particles are the result of interactions between material properties and the modes of size reduction like shear, impact, and attrition. The fundamentals of size reduction of fibrous biomass are not well understood. This chapter summarizes the latest studies on modeling of size reduction of lignocellulosic and woody biomass.
