Canadian satellite firm updates NS leak rates
Canadian satellite operator GHGSat, which has deployed a constellation of six satellites to monitor global methane emissions, said October 5 updated measurements of natural gas leaking from Nord Stream pipelines under the Baltic Sea had tripled from original estimates.
The latest measurements, recorded September 30, indicate a leakage rate of some 79,000 kg/hour from the Nord Stream 2 pipeline, up from initial measurements the same day, from a different satellite, of 29,000 kg/hour. The larger measurement is the equivalent to the emissions released by burning more than 2mn pounds of coal in an hour.

“What our satellites observed is a significant emission coming from one of the four leaks in the Nord Stream 2 pipeline and underscores the critical role technology can play in a crisis situation,” GHGSat CEO Stephane Germain said. “Moving forward, satellite observations and data will play an increasingly important role in the detection and mitigation of significant emissions, such as this.”
On October 2, the Danish Energy Agency announced that all four leaks from the two Nord Stream pipelines had been stopped, which was confirmed the following day by GHGSat observations.
