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.

However, industry has yet to provide the kind of comprehensive data needed to estimate how far any possible climate benefits from switching to blue hydrogen produced by the planned projects may offset the residual CO2 emissions and methane leaks associated with making it.

We are betting the bank on hydrogen. But are we ready for it?

Envirotec Magazine

Researchers of the University of Groningen discuss the challenges it currently presents. Just after the Big Bang, the universe was shrouded in a mist of hydrogen, and this oldest element is still all around us: in water (H 2 O), natural gas (with main component methane CH 4 ), and ammonia (NH 3 ).

ExxonMobil Urges EU to Remove ‘Policy Hurdles’ Slowing Oil Industry’s Hydrogen Plans

Currently, more than 99 percent of hydrogen used in the EU is “grey hydrogen” made from natural gas in a process known as “steam methane reformation” that has high carbon dioxide (CO2) emissions. It could also contribute to increases in ground-level ozone pollution — which is harmful to human health.

Nitrous oxide levels are on the rise

Envirotec Magazine

Nitrous oxide is a greenhouse gas and one of the main stratospheric ozone depleting substances on the planet. Widely known as “laughing gas”, used for its anesthetic effects, nitrous oxide (N2O) is also regarded as the third most important long-lived greenhouse gas, after carbon dioxide (CO2) and methane.

MIT Study Shines a Light on Hydrogen and Natural Gas in the Leak Debate

Hydrogen Fuel News

The study found that hydrogen leaks, though impactful, are about three times less damaging to the climate than methane leaks (the primary component of natural gas) on a per-mass basis. When hydrogen leaks, it reduces atmospheric hydroxyl radicals (OH), which act as natural detergents by breaking down methane.
