Renewable natural gas - or RNG - is methane produced by decomposing organic matter. The key to National Grid’s plan is using their same pipeline distribution system, but providing a different mix of gas, said Stephen Woerner, regional president of the utility: “We eliminate fossil fuels and we replace them with renewable natural gas and green hydrogen.” Thousands of miles of pipes in Massachusetts leak methane, and are being repaired and replaced at an estimated cost of $20 billion. Methane, the main component of natural gas, has a shorter lifespan than carbon dioxide, but is far more effective at trapping heat. By mid-century, if the company fails to change its business model, the net-zero requirements of the state climate law will essentially put it out of business.
The company’s “clean energy vision” is designed to transform the way the gas utility provides heat throughout its New England territory, while continuing to rely on its vast gas infrastructure.Ĭurrently, most homes and businesses in the region burn natural gas for heat, which National Grid distributes to customers through a network of pipelines. National Grid today released a plan to go fossil-free in order to meet Massachusetts’ 2050 net-zero climate emission targets. (Charles Krupa/AP) This article is more than 1 year old.
