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.

The impact of poor air quality The release of greenhouse gases into the atmosphere is well known to contribute to climate change, with carbon dioxide and methane being the subject of many global and national mitigation strategies that aim to break the vicious cycle of global warming. trillion, equivalent to 6.1 Accessed 03.03.23
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 ).
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 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.
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.
Several light hydrocarbons, such as methane, ethane and propane, are VOCs. Especially methane is a potent greenhouse gas, contributing to climate change. Several other VOCs including ethane, propane, butane, pentane, and hexane react with NOx to form ground level ozone which has harmful effects on human health and on plants.
These facilities can present a variety of potential hazards to human health. The company’s products are employed in commercial, institutional, municipal and light industrial markets, and in a wide variety of applications. New market example: cannabis cultivation.
One of the major obstacles to using hydrogen vehicles is the scarcity of fuelling stations – at present there are only around 60 in the whole of the US, for example, all located in California, with the number expected to swell to a more 100 by mid-2023.
You’ll understand what products and processes emit g reenhouse gases (GHGs), including the carbon-containing gases carbon dioxide and methane. At present, calculating a carbon footprint is completely voluntary, but has gained traction due to increasing stakeholder interest. Your carbon footprint can then be managed once understood.
The International Geoshpere-Biosphere Programme and Stockholm Resilience Center published a dashboard of 24 indicators that each depict a synchronous acceleration of upward trends from the 1950s to present day. If this permafrost thaws, it will release CO2 and methane which can even further accelerate global warming.
Coalition of campaign groups present wide-ranging plan to help countries meet and exceed the cuts the promised to make through the Global Methane Pledge. More than 110 countries have since signed the Global Methane Pledge, promising to reduce worldwide emissions of methane by 30 per cent by 2030, relative to 2020 levels.
Hydrogen is also present in compounds like methane and coal. produces annually comes from methane via steam reforming. These researchers theorized that oxidized hydrogen would cool the stratosphere and make more clouds, adversely affecting the polar vortex and increasing the holes in the ozone layer.
A carbon dioxide equivalent is a standard unit for counting greenhouse gas (GHG) emissions regardless of whether they’re from carbon dioxide or another gas, such as methane. This can present challenges which it’s important to be mindful of. As we know, GHG emissions are mainly carbon dioxide (CO 2 ).
On clear nights, he says, he can see the flares burning, releasing a gas cocktail of carbon monoxide and methane. By early June, the monitors registered a three-hour spike in ozone levels, which, if sustained over time, Nye said, would exceed federal guidelines. Ozone is an ingredient in smog and a respiratory irritant.
Hydrogen presents significant challenges when it comes to storage, given its molecular size and highly corrosive nature. It is also a more potent greenhouse gas than previously assumed, although these effects come about indirectly, when it interacts with other atmospheric gases to form methane and ozone.
While CO 2 may be the greatest contributor to climate change, other gases such as methane and nitrous oxide are also responsible for creating the greenhouse effect, therefore, solutions must also focus on the reduction of these gases. The severity of those impacts is tied directly to the amount of carbon dioxide we release.”
