Exploring underwater methane sources with mass spectrometry

Envirotec Magazine

In December 2022 the research vessel Polarstern explored methane sources in the South Atlantic using an underwater mass spectrometer. Enormous amounts of methane are trapped in the ocean floor worldwide. Methane is a harmful greenhouse gas. The higher the data density, the more accurate the mapping of methane sources.

Travel emissions drop added to lockdown methane surge, says new research

Envirotec Magazine

Reduced transport emissions led to lower levels of hydroxyl radicals – which could be said to act like a detergent to remove methane from the atmosphere, researchers say. Until now, the causes of the 2020 surge in methane – second only to carbon dioxide as a driver of climate change – had been unclear. ppb in 2019.

Wastewater sector emits nearly twice as much methane as previously thought

Envirotec Magazine

Municipal wastewater treatment plants emit nearly double the amount of methane into the atmosphere than scientists previously believed, according to new research from Princeton University. If the results from those 63 plants are representative, actual methane emissions from wastewater treatment facilities across the U.S.

Cheltenham methane leak detected from space

Envirotec Magazine

In what seems to be a first, a UK methane leak has been spotted from space, and mitigated. Methane leaking from a faulty pipe in Cheltenham, Gloucestershire, was picked up by satellites orbiting 500km overhead in April 2023. The source, near Cheltenham, was releasing methane at a rate of over 200 kg/hr.

UK substantially underestimates its methane emissions from oil and gas production – and many other countries probably do too

Envirotec Magazine

A newer, more accurate method for calculating methane emissions from offshore oil and gas production suggests that the United Kingdom severely underestimates its greenhouse gas emissions. Researchers conclude that as much as five times more methane is being leaked from oil and gas production than reported.

Measuring methane at landfill sites using drones

Envirotec Magazine

Viridor is working with UAV expert High Compliance, to understand the flight characteristics required for effective methane emissions surveys. The company has established a project team to plan a series of methane measurement surveys across several UK sites. Methane is a product of the waste we receive and outside of our control.

Measurements show huge methane peaks in the atmosphere after the Nord Stream leaks

Envirotec Magazine

The methane leak resulting from the damage to the Nord Stream gas lines in the Baltic Sea is estimated to be equal to the size of a whole year’s methane emissions of a country like Denmark or a city the size of Paris. Several ICOS stations in the Nordics observed huge methane peaks after the Nord Stream pipes were damaged.
