If completed, the Mountain Valley Pipeline will be a very large and long-lived methane delivery device. At the end of the line, the methane will be burned in power plants and furnaces, producing carbon dioxide. But now that wind, solar and battery storage are indeed quite ready and, in many places, cheaper than gas, the jig is up. Though the assertions that the pipeline is necessary and good for the climate defy logic, the political calculus is clear enough. Mr. Manchin was also a supporter of another large gas pipeline that would have originated in his state: the Atlantic Coast Pipeline, which I have been reporting on since 2019.
