Due to environmental concerns and cost issues, coal is currently being phased out from usage in electricity production. Regardless, there remains a massive stockpile of coal reserves along with a large industrial complex and a robust distribution/processing infrastructure. As such, coal should be considered for usage in other energy areas. Since coal is simply a solid hydrocarbon, it can be converted over for usage as a transportation fuel. The Fischer-Tropsch process that underlies this conversion is well established with some countries like South Africa currently using it at large scales. Unfortunately, this conversion process has a large carbon footprint, even when using carbon capture technology. However, the blending of coal-based fuels with biodiesel has been found to be more carbon neutral than standard diesel or biodiesel alone. Additionally, coal can be used as an alternate to methane for hydrogen production. Given carbon capture technologies and the existing coal infrastructure, these two uses of coal provide opportunities for a sustainable and economical use of coal as a transportation fuel.

由于环境问题和成本问题，煤炭目前正在逐步停止用于电力生产。无论如何，仍有大量煤炭储备以及大型工业综合体和强大的分销/加工基础设施。因此，应考虑将煤炭用于其他能源领域。由于煤只是一种固体碳氢化合物，它可以转化为运输燃料。作为这种转化基础的费-托工艺已经在南非等一些国家得到广泛应用，目前正在大规模使用它。不幸的是，即使使用碳捕获技术，这种转化过程也会产生大量碳足迹。然而，已发现煤基燃料与生物柴油的混合比标准柴油或单独的生物柴油更能实现碳中和。此外，煤可作为甲烷的替代品用于制氢。鉴于碳捕获技术和现有的煤炭基础设施，煤炭的这两种用途为可持续和经济地使用煤炭作为运输燃料提供了机会。
