In recent decades, many countries have shown a growing interest in Underground Coal Gasification (UCG) as a potential clean and environmental-friendly means of harnessing coal energy for power generation, and production of hydrogen, diesel fuel, etc. While Bangladesh may have good UCG potential that can be utilized to alleviate the country's current energy scarcity, this avenue has remained completely untapped up to now. In this work, the possibility of UCG implementation in five (05) indigenous discovered coalfields of the country was evaluated for the first time by using the preference selection index (PSI) method. This novel technique was considered to prioritize coalfields for gauging UCG potential. The PSI method is chosen over numerous traditional multi-criteria decision-making (MCDM) techniques, because it selects the best alternative from given alternatives without deciding the relative importance between attributes. The study indicated Jamalganj coalfield as the most suitable for implementing the UCG technique with a 93.6% potential. The second priority is Khalaspir coalfield with around 70.0% prospect and the other three coalfields - Dighipara (64.7%), Barapukuria (63.5%), and Phulbari (58.3%) may have UCG suitability in decreasing order of preference. The deduction is expected to assist the cogitation of energy-sector researchers and facilitate the decision-making of relevant authorities, policy makers, planners, and entrepreneurs.
近几十年来，许多国家对地下煤气化（UCG）越来越感兴趣，它是一种潜在的清洁且环保的利用煤炭能源进行发电以及生产氢气、柴油等的方式。虽然孟加拉国可能具有良好的地下煤气化潜力，可用于缓解该国当前的能源短缺问题，但到目前为止，这一途径仍完全未被开发利用。在这项工作中，首次使用偏好选择指数（PSI）方法对该国五个本土发现的煤田实施地下煤气化的可能性进行了评估。这种新技术被认为可对煤田进行优先级排序，以衡量地下煤气化潜力。之所以选择PSI方法而非众多传统的多标准决策（MCDM）技术，是因为它能从给定的备选方案中选出最佳方案，而无需确定各属性之间的相对重要性。研究表明，贾马尔甘杰煤田最适合实施地下煤气化技术，潜力为93.6%。其次是哈拉斯皮尔煤田，前景约为70.0%，其他三个煤田——迪吉帕拉（64.7%）、巴拉普库里亚（63.5%）和普尔巴里（58.3%）的地下煤气化适宜性依次递减。预计这一推论将有助于能源领域研究人员进行思考，并促进相关当局、政策制定者、规划者和企业家的决策。
