Abstract

As a densely populated country experiencing rapid economic growth, Bangladesh faces a surging demand for energy. Despite efforts to develop renewable energy sources, coal remains a significant share of the energy mix with a consumption of 2,099,900 tons. However, conventional coal utilization raises environmental concerns like greenhouse gas emissions and other hazardous pollutants. To tackle these issues, viable solutions like clean coal technologies come into play. These encompass high-efficiency low-emission (HELE) power stations, carbon capture utilization and storage (CCUS) systems, integrated gasification combined cycle (IGCC), as well as supercritical and ultra-supercritical steam cycles (S/USC), providing adequate means to reduce the ecological effects tied to coal-powered electricity production. This paper asserts that the strategic adoption of clean coal technologies can play a pivotal role in shaping Bangladesh's sustainable energy future, contingent upon robust policy frameworks, environmental impact and recommend that the government must incentivize HELE, CCUS, and clean coal as well as promote international collaboration. Moreover, modern coal preparation techniques and the future research direction are also discussed in this paper and additionally this study suggests that HELE technologies are more suitable for Bangladesh than other current technologies. These strategies have the potential to yield enhanced economic benefits and offer viable solutions for achieving the clean and efficient conversion of coal resources.

可持续能源的创新之路:孟加拉国洁净煤技术的进步--综述
作为一个人口稠密、经济快速增长的国家,孟加拉国面临着能源需求激增的问题。尽管孟加拉国努力开发可再生能源,但煤炭仍在能源结构中占有重要份额,消耗量达 209.99 万吨。然而,传统的煤炭利用方式引发了温室气体排放和其他有害污染物等环境问题。为了解决这些问题,清洁煤炭技术等可行的解决方案应运而生。这些技术包括高效低排放(HELE)发电站、碳捕集利用与封存(CCUS)系统、整体煤气化联合循环(IGCC)以及超临界和超超临界蒸汽循环(S/USC),为减少煤炭发电对生态环境的影响提供了充分的手段。本文认为,战略性地采用洁净煤技术可在塑造孟加拉国可持续能源未来方面发挥关键作用,但这取决于强有力的政策框架、环境影响,并建议政府必须激励 HELE、CCUS 和洁净煤,并促进国际合作。此外,本文还讨论了现代煤炭制备技术和未来的研究方向,并认为 HELE 技术比其他现有技术更适合孟加拉国。这些战略具有提高经济效益的潜力,并为实现煤炭资源的清洁高效转化提供了可行的解决方案。
