摘要

本研究对喀麦隆农村地区电气化和烹饪的一些能源系统进行了技术、经济和环境分析。看来，最经济的解决方案是将沼气用作烹饪燃料和发电（BG/Bgc系统），LCOE为0.000622千瓦时- 1美元。使用光伏能源进行电气化和电烹饪的PV/BT/Ec系统是最佳的环保解决方案。PV/BT/LPG、BG/Bgc和BG/Ec系统的二氧化碳减排率分别为86.694%、83.962%和73.373%，也是很有前景的环保解决方案。对研究区域沼气潜力的经济分析表明，沼气作为烹饪燃料的商业化比沼气发电的商业化更有利可图。在25年的项目周期内，总收益为66,865,000美元，投资回收期为13年5个月24天。

Profitability analysis of renewable energy technologies for electrification and cooking in rural areas

This study proposes a technical, economic and environmental analysis of some energy systems for electrification and cooking in a rural area of Cameroon. It appears that the most economical solution is based on the biogas used as cooking fuel and for electricity production (BG/Bg_c system) with a LCOE of $0.000622 kWh⁻¹. The PV/BT/E_c system using PV energy for electrification and electric cooking is the best environmental solution. The PV/BT/LPG, BG/Bg_c, and BG/E_c systems, respectively with a CO₂ emissions reduction rate of 86.694 %, 83.962 % and 73.373 % also appear as promising environmental solutions. The economic analysis of the biogas potential in the study area showed that the commercialization of biogas as a cooking fuel is more profitable than the commercialization of electricity produced from biogas. A total benefit of $66,865,000 could result over the 25-year project lifespan with a payback time of 13 years 5 months 24 days.
