提供了更清洁的能源未来,但比天然气带来更高的安全风险. 蓝色的排放量较低,尽管生产成本较高,但在经济上仍然可行.
科学领域:
- 能源科学与技术 能源科学与技术
- 化学工程是化学工程的组成部分.
- 环境科学环境科学
背景情况:
- 是全球能源转型中的关键替代燃料.
- 天然气 (NG) 是一种主要的化石燃料,具有成熟的基础设施.
- 需要进行比较分析,以了解对NG的生存能力.
研究的目的:
- 进行技术经济分析,比较气和天然气.
- 评估安全风险,能源输出,排放和成本效益.
- 为气和液化天然气实施战略提供见解.
主要方法:
- 技术经济比较分析.
- 对安全危害的评估 (可燃性范围,点火能量,火焰速度).
- 计算每公斤天然气,液化天然气,灰色和蓝色的能量输出和二氧化碳排放量.
主要成果:
- 气比天然气具有更高的安全风险. 能量输出随着转换而减少:NG (48.60 MJ/kg) >LNG (45.96 MJ/kg) >灰色 (35.45 MJ/kg) >蓝色 (31.21 MJ/kg).
- 每公斤二氧化碳排放量:NG (2.72公斤)
- 经济可行性:灰色是最有利可图的 (0.609美元/公斤NG),其次是蓝色 (0.390美元/公斤NG) 和液化天然气 (0.061美元/公斤NG).
结论:
- 利益相关者必须权衡能源效率,环境影响和采用气的经济因素之间的权衡.
- 蓝色是一种可行的选择,减少了排放和利能力,尽管生产成本更高.
- 技术经济分析对于在能源转型中做出明智决策至关重要.
