This is a bad article. Its misrepresenting the paper its based on.

The study this article is based on was represented here on Lemmy 4 days ago with a much better (but still not great) article. That Lemmy conversation is : HERE

I'll post here the important piece I posted there:

The study author’s argument isn’t against methane or even fracking per se. Its against the extra pollution from EXPORTING methane by ships.

I would paraphrase the study author’s position more clearly as: “A ship full of coal produces less pollution than a ship full of liquid methane because of all the leakage and energy needed to make that ship full of methane then back to burnable natural gas”

If I'm not mistaken, coal mining itself is a major methane emitter. I wonder if they account for that in this comparison?

We need real action on power - renewables and nuclear are the future.

[–] TehBamski@lemmy.world 2 points 4 weeks ago (1 children)

1000% agree.

It can become frustrating to learn or deal with people who haven't informed themselves about the advancements in nuclear power. Safer methods of energy generation have been developed since the Fukushima incident (March 2011.)

[–] xmunk@sh.itjust.works 2 points 4 weeks ago

Honestly, at the time Fukushima happened the reactor was already decades out of date - we had technology at the time that would have prevented any disaster (i.e. molten salt reactors using thorium that self destruct safely if a chain reaction occurs).

Two of the renewables are intermittent: solar and wind.

They only provide energy some of the time.

That means that you need to have something else to step in when they aren't providing energy.

We don't have the capacity to just store all that energy when they are outputting power to fill in those gaps. Batteries aren't even remotely-feasible. Pumped hydrostorage is our best option, but you can only do that in places with favorable geography.

What it generally means today, in practice, is that if someone is using solar or wind, they used to use coal and now use natural gas to fill in those gaps. If you use solar or wind, you're also tying yourself to natural gas.

For a number of places, if you're using natural gas, you cannot pipe it in. Like, take Guam. They're a little island out the middle of nowhere. They can't pipe in natural gas, need to have it converted to LNG so that it can be shipped in. Europe has some natural gas, but less than the US, and unfortunately two of the convenient neighboring places to get it that might pipe it in are Russia, which promptly started using said pipelines as leverage, and Africa, which has countries that would like to sell it to Europe but suffer from political instability.

If your natural gas pipeline gets too long, then LNG becomes more-efficient. LNG has something like an IIRC 30% overhead to liquify it, but once you do that, you're mostly done. With a pipeline, you have to keep pumping it to keep the gas moving. There's a break-even point where LNG becomes more-efficient if you have to move it further. I looked that up at one point, and IIRC, even security and practicality issues aside, it wouldn't be economically-viable to run a trans-Atlantic pipeline: LNG is more-energy efficient, because the distance is so far.

Hydroelectricity is renewable and doesn't have that problem (well, barring extreme, extended droughts, but it comes with a lot of flexibility in generation), but it's limited by geography; you can only put hydroelectric dams in some places. Also, there are some people who get upset about the ecological impact on rivers, since it changes whether fish can go up and down the river and when and how much water flows.

Geothermal power is renewable and also doesn't have that problem, but is also limited by geography.

With nuclear, you've got a raging anti-nuclear crowd.

EDIT: One point in LNG's favor -- I went reading about current LNG systems a while back. They're...presently not very efficient, and it'd be possible to do engineering work on them to improve efficiency. Basically, if you're liquifying LNG in the US and shipping it to Germany and then regassifying it, you're running what amounts to a gargantuan air conditioner compressor. You're making the gas very hot in the US, then producing very cold output decompressing LNG in Germany. Right now, the heat and coolness on each end are "thrown out", not used for other processes, which is why there's overhead. So, IIRC Germany is (or was during the crisis, dunno what's going on now) using floating LNG regassification plants, things that are basically converted LNG tankers. Those things deal with all the coolness they're generating by having their LNG regassified by dumping it into the water. So we're spending a lot of money and energy to heat up water or air or something in the US and then chill German port waters (in fact, I was reading some article a while back that people were a bit worried about the ecological impacts of the chilling). It'd be possible, if you were going to use LNG, to reuse some of that energy, which would avoid that waste.

In California, part of the California State Water Project involves pumping water up over the mountains to where it's needed. That costs energy. But it's set up to recover some of the expended energy by having the descending water drive hydroelectric power plants. Same kind of idea -- you can refine the process to eliminate overhead.

geothermal is not really limited by geography as its really down to drilling depth. there is a laser drill tech that may allow for way more. Then also upfront cost vs long term as most houses could save on heating and cooling with geothermal that does not go very deep.

No. With nuclear you have very real unmitigatable risks and very real insanely high costs. Which also don't solve anything as nuclear production isn't fitting demand fluctuations either, so you still need mass storage (or waste overproduction 90% of the time, combined with already insane costs).

The raging crowd is the pro-nuclear cult on social media that ignores reality and sputters sci-fi fairy tales all day long in the name of their savior.
