Reuters report that the leak rate of methane from the damaged pipes is 22920 kg per hour. The ruptures on the Nord Stream natural gas pipeline system under the Baltic Sea have led to what is likely the biggest single release of climate-damaging methane ever recorded, the United Nations Environment Programme said on Friday.
Interesting to also compare and contrast the rates of methane release supposedly coming from the melting of the Siberian permafrost. According to wikipedia(!) this is 17 million tonnes a year, or 0.3 million tonnes a week?
I read somewhere that as the valves are turned off all that's escaping is the gas in the pipes, and this in total is about the same as Germany typically uses in 2 days. So a lot of gas to waste but over a year and globally it's not a significant release.
