“…Although the evidence analyzed does not include anything substantial about air pollution, an inference could be made given the GHG reduction scope of the project. A comparison [67] of pollutant emissions between biomass-and diesel-based power generation shows that bioenergy reduces SOx and NOx emissions but is higher on the scale (on per MWh basis) when it comes to PM10 (Particulate matter of 10 micrometers or less) emissions. Having said that, given the size of many small remote communities, air quality is often not a major concern in terms of energy production, a point emphasized by the Executive Director of Alaska Energy Authority: "Most of the communities with these systems do not have air quality issues and this is not a major concern" (M01).…”

Harvesting Local Energy: A Case Study of Community-Led Bioenergy Development in Galena, Alaska

et al. 2022

Community-led bioenergy projects show great promise to address a range of issues for remote and Indigenous Arctic communities that typically rely on diesel for meeting their energy demands. However, there is very little research devoted to better understanding what makes individual projects successful. In this study, we analyze the case of the Galena Bioenergy Project (Alaska)—a biomass heating project that uses locally sourced woody biomass to help meet the heating demands of a large educational campus. Using project documents and other publicly available reports, we evaluate the project’s success using three indicators: operational, environmental, and community level socio-economic benefits. We find that the project shows signs of success in all three respects. It has a reliable fuel supply chain for operations, makes contributions towards greenhouse gas reductions by replacing diesel and has improved energy and economic security for the community. We also examine enabling factors behind the project’s success and identify the following factors as crucial: community-level input and support, state level financial support, access to forest biomass with no competing use, predictable demand and committed leadership. Our findings have important implications for other remote communities across the Boreal zone—especially those with nearby forest resources. Our examination of this case study ultimately highlights potential pathways for long-term success and, more specifically, shows how biomass resources might be best utilized through community-led initiatives to sustainably support energy security in Arctic communities.

Techno-Economic and Environmental Performance of Two Distinct State-of-the-Art Solar-Assisted District Energy System Topologies

This study introduces a novel, ambient-temperature district energy system topology that enables bi-directional mass flow to booster heat pumps and includes distributed solarthermal generation. The ambient system topology is described, and a corresponding detailed model is developed in the MATLAB-Simulink® environment. An equivalent model is developed for a conventional, supply-return district system utilizing hot water (at 75°C) and chilled water (at 15°C), allowing for the direct comparison with the proposed topology-both with and without solar-thermal integration-in technical, environmental, and economic analyses. Technical performance is assessed using a system coefficient of performance and solar fraction, environmental performance is estimated using carbondioxide equivalent emissions, and economic performance is characterized using a levelized cost of energy approach. Annual simulations are conducted for the case study of an urban district energy system in Ottawa, Canada, connected to 12 commercial building clusters.The ambient-temperature system achieves an annual system coefficient of performance of 1.40 without solar assistance and 1.43 with solar assistance. The conventional system achieves annual coefficients of performance of 1.26 and 1.28, respectively. The solar fractions of the ambient and conventional systems are 5.5 and 4.0% for heating and 9.3 and 10.0% for cooling, respectively. Despite these noted improvements in performance with solar-thermal, the technical findings indicate that the rooftop solar collection fields are undersized relative to system loads due to rigid rooftop space constraints. Nonetheless, the ambient system (without solar) decreases annual carbon emissions by 32.16% relative to the conventional system, a significant improvement. Furthermore, while the ambient system's levelized cost of energy is higher than the conventional both without solar (8.1 iii vs. 6.0¢/kWh) and with solar (11.0 vs. 9.2¢/kWh
