Coal-to-gas switching in the power sector, as happening in the U.S., has been a key driver of near-term greenhouse gas emissions reductions. Can this success be replicated around the world? Here, we explore the limits of a global, plant-level, coal-to-gas transition arising from pipeline availability constraints. Globally, only 43% of coal capacity is within 14 km of a nearby pipeline, the median distance for recent coal-to-gas conversions. Furthermore, plant-to-pipeline distance distributions vary widely–only 30% of coal capacity in India is within 14 km of a nearby pipeline. Most global coal fleets are in the intermediate space of balancing two competing interests–having a young coal fleet with high “avoided” emissions potential through coal-to-gas switching but without access to low-cost gas resources. A global stocktake based on coal fleet age, pipeline access, and natural gas supply security suggests that a coal-to-gas transition in the power sector is unlikely to be a universal climate solution.

电力行业全球煤改气可行性的管道可用性限制

正如在美国发生的那样，电力部门的煤改气一直是近期温室气体减排的关键驱动力。这种成功能否在世界范围内复制？在这里，我们探讨了由管道可用性限制引起的全球工厂级煤制气过渡的局限性。在全球范围内，只有 43% 的煤炭产能位于附近管道 14 公里范围内，这是近期煤改气的中位距离。此外，工厂到管道的距离分布差异很大——印度只有 30% 的煤炭产能位于附近管道 14 公里范围内。大多数全球煤炭船队处于平衡两个相互竞争的利益的中间空间——拥有一支年轻的煤炭船队，通过煤改气转换具有很高的“避免”排放潜力，但无法获得低成本的天然气资源。基于煤炭船队年龄的全球盘点，
