Final version of my paper on the GHG footprint of LNG exports from the US is now published. Conclusion? LNG has a larger climate impact than any other fossil fuel, including coal. http://doi.org/10.1002/ese3.1934

Congrats. You've suffered a lot of slings and arrows. Hopefully the rigorous science you've put in this paper will finally silence the LNG defenders or at least put them in their place.
For upstream + midstream methane, 2.8% of production, plus emissions from liquefaction plant, tankers, etc. Keep in mind that a lot of gas is burned to power the liquefaction & tankers, which has a multiplicative function on the upstream & midstream methane. Most CH4 emissions are not "leaks"
Cool thx - much appreciated, both your work and taking questions!
Right.
And if we electrify liquefaction...?
I'm in bc, Canada and they're threatening to make taxpayers subsidize LNG with cheap clean power so they don't cook us all.
Electrify the liquefaction of gas? No. We need all the electricity we can get for beneficial electrification of heating and transportation. And we need to move towards 100% renewable electricity. Using electricity to prop up the natural gas industry is just wrong.
Copy that. I'm sold. It's what's being discussed here as part of the argument for making fracked gas into a "climate solution".
But I agree. Bad plan. Just wrong. :)
Qatar isn't that far behind, its gas is offshore and relatively easy to recover and transport and they aren't fracking shale to get it. I'd be interested if that made a difference
Of course it would, but is it significant is the question
It would be a bit disappointing to think in the week the UK decommissioned its last coal plant that the Qatari gas is just as bad
Although you can use gas to balance for wind intermittency, which you can't do with coal, so it is still better for the overall emissions from the grid
No, Europe has responded by greatly reducing gas use over past 2 yrs. They do not need any more LNG from the US. That's a false narrative promoted by oil & gas.
Europe, and other regions depending on russian gas are far from having ditched out russian gas completely, this is not oil and gas propaganda but a fact.
That's true in the UK, more wind and solar generation reduces the amount of LNG imported. Power generation here is currently 30% of the total demand. It's often less as winds are light today.
Reduction of fossiles is s must and always possible, however one has to understand that decarbonisation is on a one order magnitude longer timescale than mitigation of a crisis as the russian genocide. Always and everywhere
Most of the natural gas in the UK comes from the Norwegian sector of the North Sea. My whole working life was in the UK gas industry starting before conversion to Natural Gas from manufactured towns gas. It's clear we need to reduce burning fossil fuels of all kinds.
You can have worked in the gas industry since the fossilation of its generating microfauna, but what I said above stands correct.
Europe is still depending on russian gas and we need the US shale gas for a long phase out time
It was a strategic error for Europe to become so dependent on Russian gas, it was abundantly clear what Putin was like after he took power. I don't disagree with your views, the dependency on Russian gas is much reduced but still there.

Did u double check? ;)
What leakage rate is assumed here? I think 4% was the breakeven I last read.
What if we get all those pipe fittings good'n'tight?
Right.
And if we electrify liquefaction...?
