Scenario analysis of Taiwan's nuclear phase‐out strategy with time series forecasting

AbstractElectricity generation in Taiwan is mainly from thermal, nuclear, and renewable sources. With nearly four decades of monthly data (from January 1982 to January 2022) used in analytics, the forecasting results reveal the patterns of electricity generation in Taiwan. Exponential smoothing and Holt–Winters seasonal models are used for time‐series forecasting, and scenario analysis is applied to simulate possible paths for nuclear phase‐out in Taiwan by 2025. Taking the fact of Taiwan's lack of energy independence into account, transition for nuclear phase‐out may require a substantial leap to meet the demand. The feasibility of electricity generation using current thermal power capacity and renewable energy remain challenging.

Environmental and Economic Assessment of Wood Pellet Production from Trees in Greece

Biomass is a renewable, economic and readily available resource of energy that has potential to substitute fossil fuels in many applications such as heat, electricity and biofuels. The increased use of the agricultural biomass can help the agricultural based societies in achieving energy security and creating employment without causing environmental degradation. However, the viability and feasibility of electricity generation from agricultural biomass depends upon the availability of biomass supply at a competitive cost. The present study investigates the availability of agricultural biomass for distributed power generation in Greece (Kozani). The study concludes with a discussion on significance and challenges of decentralized electricity generation for rural energy supply, including brief description about economical, social, environmental and technical aspects of bioelectricity. With the application of the life cycle analysis applied, the environmental and economic impacts that will occur in the region of Kozani in Greece, where a biomass wood pellets production workshop is operating, have been assessed. The total annual emission of CO 657.9 gr, HC 22.36 gr, PM 67.94 and NOx 8.832,2 gr was calculated. The economic evaluation estimated the payback period for the investment in this plant to be approximately 3 years.

Study on the Feasibility of Electricity Generation from Biogas Produced from Municipal Solid Waste and the Biodigestion of Henhouse Manure

Despite consisting of residual material in some processes, solid waste still presents huge potential for recycling, reuse, and energy use, either through thermochemistry or biochemistry. Municipal Solid Waste (MSW) can be energetically exploited by converting landfill gas (LFG) to electrical energy. In addition, animal manure can also undergo biodigestion, generating biogas that can also be harnessed energetically. Achieving economic viability is difficult when evaluating Thermal Power Plants (TPP) using biogas, especially in cases of smaller cities (in the case of LFG) or when animal populations (biodigestion) are smaller. This study presents three scenarios for electricity generation using biogas in a case study of a small city located in Itanhandu (MG), Brazil. This study sought to evaluate the benefits of using two sources for biogas production, these being LFG and the anaerobic digestion of henhouse manure. In the first scenario, a project generating electricity using LFG was analyzed. In the second scenario, energy was generated via biogas coming from manure collected at henhouses. The third scenario considered electricity generation from both sources. The results demonstrate that TPPs based only in LFG are not economically viable, while the other two scenarios present positive results as to their economic viability, showing that the biogas volume coming from manure collected at henhouses is sufficient for electricity generation at the TPP with landfill gas. This result could be beneficial both as a solution for Solid Waste Management (MSW) as well as providing an additional energy generation solution near to the city.

Feasibility of electricity generation using WECS in the selected locations of Tigray region (Ethiopia)

This paper presents the feasibility of electricity generation using WECS in the selected locations of Tigray region in Ethiopia. Weibull parameters were obtained using the energy pattern factor method (EPFM). A linear agreement was observed between mean wind speed and power density. Analysis of the present value of cost per kilowatt hour was estimated for selected wind turbines at different hub heights. In addition, regardless of the location, power law curve fit provides higher regression than the linear curve fit. From the analysis of results and discussion, it is revealed that (WECS)III has the least progressive ratio when compared with (WECS)IV. Finally, the average specific cost per unit for all chosen turbines at Mekele and Chercher is comparable to the cost per kWh charged by EEPCo, except for a few turbines in this study.

Electricity generation from Taihu Lake cyanobacteria by sediment microbial fuel cells

AbstractBACKGROUND: Cyanobacteria are rich in carbohydrates and proteins as well as other nutrients. In recent years, its efficient treatment and utilization has become an important topic for debate. The feasibility of electricity generation from Taihu Lake cyanobacteria by sediment microbial fuel cell (SMFC) was investigated and its performance evaluated by comparing with glucose‐fed and acetate‐fed SMFCs.RESULTS: A SMFC using acidic fermentation broth of Taihu Lake cyanobacteria generated a maximum power density of 72 mW m−2 with COD removal of 76.2% and substrate degradation rate (SDR) 0.607 kgCOD m−3 d−1. A power density of 51 mW m−2 with COD removal of 72.0% and SDR of 0.573 kgCOD m−3 d−1 were obtained with an acetate‐fed SMFC. The redox peaks in the voltammogram curves of the SMFC fed with acidic fermentation broth of Taihu Lake cyanobacteria suggested mediating compounds existed during its stable operation. The electron transfer was possibly carried out by cell‐bound redox components or biofilm formation with electroactive bacteria on the anode surface.CONCLUSIONS: This paper describes a potential method to recover sustainable electricity from Taihu Lake cyanobacteria, and the acidic fermentation of pretreated cybanobacteria could significantly enhance the power output and COD removal.

Electricity Generation from Leachate Treatment Plant

Tehran has a population of over 12 million and produces more than 7500 tons of waste every day. Tehran’s municipal solid waste is processed and landfilled at Kahrizak disposal center. Due to inappropriate waste management, a lake with a leachate volume of 180,000m3 has been formed. To solve this problem a leachate treatment plant is currently under construction. A byproduct of leachate treatment is biogas. In this study, the feasibility of electricity generation using biogas has been investigated. Considering that 68.81% of the waste is degradable, the produced leachate has a high organic load (COD = 53900 mg/L and BOD = 34400mg/L). The results showed that a power plant with a capacity of 1.8 MW could be constructed in the site. This electricity can be utilized in Kahrizak Disposal Site and also sold to the network (10 US cents/ kilowatt). Financial analysis using ProForm software shows 1.3 years of payback period and emission reduction of carbon dioxide equal to 5752 tones/year in comparison with the natural gas power plant. Therefore this project is financially feasible for private investors with internal rate of return equal to 77% or mo

The membrane-less SMFC developed voltage gradient of 0.78 to 0.8 V with maximum power of 0.014 mW/cm2 observed at 10 I©. Maximum current density of 67.85 × 10-6 (mA/cm-2) and power density of 52.92 × 10-6 (mW/cm-2) was recorded. Native bacterial culture present in dairy waste sediment was used as catalyst for electricity generation. Bacteria present in dairy sediment showed the potential to generate electricity without any mediators (redox dyes). Production of renewable energy (bioelectricity) utilizing organic substance is an economical and sustainable process.
