This week, the world watched what’s prone to be the fossil gas business’s single largest methane launch ever. An astonishing quantity of methane is floating up from the now-notorious Nord Stream 1 and a couple of pipelines and rising above the floor of the Baltic Sea. It’s a air pollution nightmare. It additionally pales compared to the huge quantity of methane that oil and gasoline operations always launch.
As much as 778 million customary cubic meters of methane gasoline might spew from the Nord Stream 1 and a couple of pipelines in a worst-case situation, in response to the Danish Vitality Company. That’s equal to just about a 3rd of Denmark’s greenhouse gasoline emissions for the whole yr of 2020.
The Nord Stream catastrophe “is an awfully large one-time occasion,” says Andrew Baxter, a chemical engineer turned director of vitality transition on the Environmental Protection Fund. “But it surely’s kind of emblematic of different large emissions from the oil and gasoline business of methane into the ambiance.”

As huge as this occasion is, runaway gasoline from the Nord Stream pipelines quantities to a fraction of the methane that routinely escapes from oil and gasoline fields, pipelines, and different infrastructure. Defective gear can leak for weeks. Corporations additionally “vent” gasoline — releasing it into the air — for nicely or pipeline upkeep or to maintain strain from constructing as much as harmful ranges of their gear. The oil and gasoline business releases 82.5 million tons of methane emissions a yr, by the Worldwide Vitality Company’s measure. That’s equal to the worst-case situation for the Nord Stream catastrophe going down each two days, Baxter tells The Verge. The US oil and gasoline business alone releases methane on the fee of a Nord Stream catastrophe about each two and a half weeks, local weather author and analyst Ketan Joshi calculated.
To be completely clear, what’s taking place with the Nord Stream 1 and a couple of Fuel Pipelines is much from extraordinary. “All presently accessible data signifies that that is the results of deliberate, reckless, and irresponsible acts of sabotage,” NATO mentioned in a press launch yesterday. Vladimir Putin has additionally accused Western governments of sabotaging the pipelines. The pipelines, which run from Russia to Germany, are a bodily embodiment of Western Europe’s reliance on gasoline, a lot of it coming from Russia. So earlier than fears of sabotage, these pipelines had been already a flashpoint for efforts to transition the European Union to wash vitality.
Neither is it regular to see almost half a mile of the floor of the ocean roiling with methane. The Danish Armed Forces launched mesmerizing video and pictures of the effervescent catastrophe within the Baltic this week. And whereas seawater can usually take up most of methane from smaller underwater leaks, stopping it from floating as much as the air, this isn’t the case with the Nord Stream catastrophe due to how huge the leaks are.
“The ocean can’t absorb that quantity,” says Mahmoud Khalifeh, an affiliate professor on the College of Stavanger who has researched gasoline leaks from offshore wells. Khalifeh expects greater than 90 % of the gasoline that escapes from the pipelines to make its means into the ambiance.
He additionally factors out that, in contrast to spilled oil that collects within the water, there’s not a lot that may usually be accomplished to wash up leaking gasoline. It merely dissipates into the water and air. It’s additionally harmful for authorities to ship in personnel to take care of the mess. The air high quality is just too horrendous, and sending in automobiles to wash issues up might spark an enormous blaze. In Nord Stream’s case, nonetheless, Mahmoud thinks hearth might mitigate among the dangers. Setting the methane ablaze would convert the plume to carbon dioxide, which may be 80 instances much less potent than methane as a greenhouse gasoline. It may additionally cease the methane from drifting ashore and polluting communities there. Lighting up extra gasoline, known as flaring, can be a method oil and gasoline corporations use to reduce methane emissions.
The UN Surroundings Programme launched satellite tv for pc pictures yesterday of the methane plume above the Nord Stream leaks. There are rising efforts to doc methane leaks from house as an growing physique of analysis reveals that many international locations are seemingly undercounting how a lot methane is leaking from oil and gasoline operations.
“It is a particular one-off occasion that’s obtained everybody’s consideration. However the oil and gasoline business emits tens of millions of tons of methane yearly, and that’s supercharging near-term [global] warming,” Baxter says. “I hope that this brings that into focus for extra folks, we’d like to have the ability to regulate [emissions from these] corporations and take this extraordinarily severely.”
