In a stroke of supreme irony, it turns out that natural gas is more damaging to the environment than coal, according to the latest study HERE
In a nutshell:
“Even though carbon dioxide emissions are greater from burning coal than from burning natural gas, methane emissions can more than offset this difference,” Professor Howarth wrote in the paper.
“As a greenhouse gas, methane is more than 80 times more powerful than carbon dioxide when considered over a 20‐year period and so even small methane emissions can have a large climate impact.”
According to Professor Howarth, at every point along the chain of gas production methane was found to be leaking.
So really, they should be closing down the gas-fired power stations producing 30 percent of Britain’s power and going back to burning coal.
A masterly con job by the oil and gas industry,which of course is disputing the good professor’s research, while the environmentalists are disputing the industry’s disputation. And so it goes on…
I recommend everyone read the article and make their own mind up. Hopper’s conclusions are flawed! Give ’em the third degree.
Of course leaking Methane is bad, but the report specifically addresses the rapidly growing US Liquid Natural Gas industry. That US industry has been slapdash does not mean the rest of the world is too! Nor do US gas leaks mean the UK would benefit in any way by reintroducing coal burning power stations!
That methane is a bad greenhouse gas isn’t news. What’s more interesting is the subject being raised in connection with President Biden’s decision to ban the export of US natural gas. He’s chosen to retain this particular fossil fuel for use within the US, which is bad news for countries who need to import it.
Whether or not the US clamps down on other fossil fuel exports as well remains to be seen. It’s complicated. At the moment, the US imports about 8 million barrels of crude oil per day whilst also exporting a different 10 million barrels of crude. Yer wot? The reason is a mixture of history and chemistry. For a good few decades it’s been cheaper to import crude oil into the US than to extract it locally : no more easy gushers. So for a long time most US crude has come from Canada, Mexico and Venezuela.
As these countries all produce ‘Heavy Sour’ crude – a thick goo with lots of Sulphur in it. Consequently US refineries are almost all engineered to process Heavy Sour.
All change! Today the US produces a lot of ‘Light Sweet’ crude by fracking. ‘Light Sweet’ is refined with a different chemical process than that used on Heavy Sour because it’s thinner with much less Sulphur. Bottom line, to make use of their own fracked oil the US will have to replace almost all their existing refineries. No one rushing to do that because it’s seriously big money, but the balance will shift as soon as importing Heavy Sour becomes more expensive than fracking Light Sweet.
The strategic importance of energy supply is not lost on the US government. Nor are they alone. A likely reaction when resources become short is to restrict exports. Over the next 30 years any industrial oil producing country will be much more reluctant to export oil. What’s happening may not be obvious to consumers yet, but Governments around the world have taken note. How should their country prepare for a world in which oil and gas are not cheap and abundant?
