This is just exchanging one greenhouse gas for another. Burning methane still produces carbon dioxide. That isn't "clean."

Neat concept, but we really need to lean away from any greenhouse gas emitting fuel. This is money, time, and effort that could have gone into something else. Too much combustion is the problem.

Man. I'm pretty sure cyanide is worse as far as poisons go. If we can sip antifreeze instead that's at least a little better.

None are better than another, some are merely worse. It might take more antifreeze to kill you, but they'll both kill you.

Consider methane a nearly literal greenhouse as it rapidly traps heat and co2 a wool blanket. Methane traps a lot very quickly, and CO2 keeps it here.

They both need capture and scrubbing in some nature, not conversion.

But the difference is that nobody needs to drink poison, but the world still actively and perpetually needs energy. I'm 100% in agreement that we're destroying the planet, but there needs to be time allowed for compromise and conversion to other methods unless you're planning on literally killing half the human population yourself, because that's what it'll take to convince a lot of them.

If you have three different acids, all corrosive yet some are merely more acidic than others, would you say any of them are good to pour on your face?

In the same vein, I was saying all greenhouse gasses are bad and some are worse than others. None of them are "good" all of them are "bad" it is merely that some are worse than others.

Pushing off the due date and claiming this is "clean" is bad. Offer it, utilize it as a stopgap sure... It's foolish to call it "clean" or think it "better." It is merely buying time on the clock.

Difference is this gas is already being released to the atmosphere where typical oil and gas is extracted from deep underground and added to the atmosphere. It's more like recycling rather than adding.

Except it’s not. Methane is 20 to 40 times worse for the atmosphere than CO2. It’s exchanging an extremely bad GHG for a significantly less harmful one, reducing carbon emissions impact 20-fold.

You literally said “it is not a solution”, when in fact it is very much a valid solution which significantly improves our carbon emissions. It’s not a perfect solution, but if we only pursued perfect solutions our society would grind to a halt. Perfect solutions hardly exist.

For example, if you think electrifying everything is the ideal solution you may want to look at the environmental and human rights impact of lithium and cobalt mining.

I also happen to agree mining conditions are terrible and that can be done better too. That isn't the discussion at hand. The discussion is whether this is "clean" or a "solution" and it is neither when other actual solutions exist.

How can you in one breath defend this as great yet imperfect then turn around and make such an accusation when I offer another imperfect, yet non extinction event forming solution.

Did i say it was perfect? Never made the claim. But it at least damages a country side and not the entire atmosphere and is a solution to global climate change. How the people in those mines are treated is an entirely different subject and one I happen to think needs fixing as well. You are making a lot of assumptions.

> Burning methane still produces carbon dioxide. That isn't "clean."

Methane is a much stronger greenhouse gas than carbon dioxide. They estimate this by using carbon dioxide as a baseline and calculating the Global Warming Potential (GWP) of methane. With this measure the GWP is how many multiples of the energy absorbed by the material vs that of carbon dioxide.

Methane Vs CO2: Which Is the Most Potent Greenhouse Gas As White House Unveils New Pledge

> Methane has a GWP of between 28 and 36 over 100 years, according to the EPA, meaning it is significantly more potent as a greenhouse gas than CO2.

This is the equation for burning methane: CH4 + 2O2 -> CO2 + 2H2O

That means that each liter of methane will produce one liter of carbon dioxide (equal moles are roughly equal volumes for gasses at the same temperature and pressure). So burning a liter of methane instead of releasing it is about the equivalent of saving 30 liters of carbon dioxide from the atmosphere, in terms of global warming. This doesn't include using the energy produced to reduce the amount of diesel that doesn't need to be burned to run vehicles.

That means the process the article is talking about is significantly more "clean" environmentally.

thisischemistry t1_ituy9zp wrote

Right, this is simply a bridge. It's much better than allowing methane to be released into the atmosphere and carbon dioxide to be produced from burning diesel fuel. Eventually both methane and carbon dioxide production should be reduced as much as possible through other methods.

It will take time to make that kind of transition and this is a good intermediate solution until we get there.

Calling something "clean" is a relative term. Pretty much everything is "dirty" in some sense but it can be less so than earlier methods. This idea is more "clean" than what it supplants. There are also ideas that are more "clean" than this one, but which aren't ideal at this time.

To be fair, here's what the article said:

> However, a CEFC spokeswoman added it would be open to taking on additional local fleets interested in trying the cleaner fuel.

They didn't call it "clean", just "cleaner". Yes, the company is named Clean Energy Fuels Corporation so that's a bit misleading but I can forgive it since that's a marketing thing. Calling them Cleaner Energy Fuels Corporation doesn't really ring as well.

Marketing can't just be written off an forgiven, it's the only "education" on the subject matter some people ever get. They're happy to tell a newsperson the truth because they know the average person rolling up and filling their tank didn't read it. They saw "BIOCLEAN!" and heard some marketer say "We're trapping methane and turning it into fuel, keeping the methane out of the atmosphere and helping to fight climate change!"

Then they go in thinking "wow, isn't this great. I'm doing my part!" All the whioe we ignore the CO2 emissions for another 20 years because it's "not as bad" and most people don't realize it's even producing CO2.

Then you have to tell people this beautiful clean coa- sorry, methane they've been burning is actually bad now and they need to stop. Now you're trying to wrest the wheel in a direction we could have been driving in 20 years ago, but someone's marketing team came up with a real good pitch and bent the truth just so.

It isn't marketing. It's lying.

This isn't introducing new carbon like cowboy fossil fuels does, this is carbon that was sources from the atmosphere and was going to be released back into the atmosphere as methane, which takes 20 years to decay and is 80x more potent than the CO2 it decays into anyways, so this is actually just skipping that step meaning it has a positive effect.

It isn't " clean" because it is still combusting something to produce CO2. The other greenhouse gas that, sure, might be "less bad" but is still melting ice caps and acidifying the oceans. As is the major problem with all of our excessive combustion.

That came from and would return to the atmosphere anyways. It isn't producing new carbon how is that hard to understand?

No, coal is polluting several toxic and radioactive compounds in addition to releasing new carbon. There is no such thing as "clean coal". Wildly different, and I think you only perceive it to be the same through a lack of understanding of the science and the difference between fossil sourced natural gas and methane that is already part of the carbon cycle.

That methane would not have been produced without human intervention. That is my entire point.

That many cows exist because of humans.

That much methane is produced as a part of that cycle... Because of humans.

Just because it came from and would return naturally does not mean that we are not dramatically accellerating the process.

Granted coal pollutes more, but the equivalance is there when we are talking about the precipice that we are standing on with climate change. The emitted carbons are what I'm talking about.

I'm not going to pretend I have a solution to methane, but putting it in cars and turning it into more CO2doesn't scream "clean" or "solution" to me. It screams delay and marketing.

That's a stronger argument to burn it as fuel because, and I repeat, that carbon came from the atmosphere in the first place. So if you're concerned about an increased ratio of methane, you support converting it back to CO2.

>I'm not going to pretend I have a solution to methane, but putting it in cars and turning it into more CO2doesn't scream "clean" or "solution" to me. It screams delay and marketing.

It isn't "more" because that carbon was already in the environment. It is clean because it's non-polluting. It isn't "delay" because it's in place of, carbon adding fossil fuels.

But it is... It is carbon that was trapped in grass being released as gasses. The carbon was in the environment i. The exact same way fossil fuels were.

We had cows eat grass, convert the solid, non-greenhouse carbons in that grass into methane, and we are then releasing that into the atmosphere as a gas.

This is not a direct co2 to methane to co2 process, you are ignoring where that carbon was in the first place. In plants. Just like fossil fuels... Or have we forgotten fossil fuels are mostly from plant matter?

It is absolutely more. It is taking solid carbons and releasing them as gasses producing more co2 in the atmosphere than there was before.

Not forgetting this at all, you're forgetting that most of it doesn't end up buried to eventually become fossil fuels either. Most of it is released back into the environment as methane through decay. It takes special circumstances such as pete bogs, wetlands, dense rain forest and shallow ocean basins for plant and animal matter to accumulate, be persevered and buried faster than it could decay to eventually become fossil fuels.

That is why we find fossil fuels in concentrated pockets and not as a fairly uniform distribution. Almost none of the carbon sequestered by grass on the plains grazed by cattle will end up that buried as that.

>It is absolutely more. It is taking solid carbons and releasing them as gasses producing more co2 in the atmosphere than there was before.

sigh as was already stated multiple times and as you're very last point even attempted to address, no, it is not more carbon, it is carbon that was already in the atmosphere, it is the exact amount as was there before it was captured by plants and that's where it would return or have stayed without our involvement, except it would have spent it's first 20 years after reentry as methane.

How fast do you think grass dies and decays rather than being mowed through by cows? How fast do you think it decays into CO2that isn't then immediately absorbed by the growth around it? Clear a field and kill the grass on the regular and that is not the "natural" process you're alliding to. Volcano eruptions are "natural" too, so I guess we just keep marching toward a new paleolithic era at a human-accelerated rate because "well, volcanos explode all the time."

Just because there is a natural parallel does not mean this is equivalent. You're comparing slow natural decay to rapid, acid and enzyme-based decay due to the overpopulation of a certain animal in concentrated locations.

I addressed that it is an acceleration of natural processes. Just because it would happen over time does not mean it is ok to press fast forward on the process. This is a foolish argument.

The parallel drawn was merely to point out that whether we are speaking fresh grass or old fossilized plant matter, it is still "carbon that existed in the environment." The fuel was trapped deep underground before we drilled and fracked for it. I even said I'd agree further if you were talking about someone capturing from a methane vent.

This is not that. This is taking methane that we are producing at an accelerated rate and turning it into CO2 that we will be releasing at an accelerated rate.

No matter what, this is humans still releasing solid carbons from their trapped forms into the atmosphere and accelerating the process. That is the root problem.

It isn't "clean" it isn't a "solution." It's fine and dandy as better-than-methane but at this point in the game more can-kicking isn't what we need. We need to find a way to stop releasing carbons as gasses as entirely as possible. It is, of course, going to happen... But doing it in every single vehicle is a bad idea no matter how you slice it.

You realize cows can't eat it faster than it grows and don't magically conjure more carbon into existence by doing so right? It the surrounding plants would have to wait 20 years for that CO2 to be available again and it will be available again anyways.

This isn't an argument against burning this methane, it's an argument against unsustainable farming practices. Which I'll certainly agree with you on.

>The parallel drawn was merely to point out that whether we are speaking fresh grass or old fossilized plant matter, it is still "carbon that existed in the environment." The fuel was trapped deep underground before we drilled and fracked for it.

No there is a big difference, the fossil carbon had been out of the environment for hundreds is millions of years, while the methane we're capturing and burning is actively part of the carbon cycle.

>This is taking methane that we are producing at an accellerated rate and turning it into CO2 that we will be releasing at an accellerated rate.

...You realize it's physically impossible to do that at a faster rate than sequestered right? Again, nothing in this process conjures more carbon atoms into existence and no new carbon atoms are introduced that weren't already in the atmosphere. If we are to feed cattle at an accelerated rate we must grow food for them at an accelerated rate which sequesteres CO2 at an accelerated rate. The only hitch is that methane naturally decays over 20 years and is 80x more potent than the CO2 it was before, this will rate match with it's production but we can increase the ratio, you are correct on that. Again however that is an argument for burning it to skip that time period

>No matter what, this is humans still releasing solid carbons from their trapped forms into the atmosphere and accellerating the process. That is the root problem.

No, it isn't, your entire argument is based around "we're doing this more than natural" but that starts with CO2 that was already in the atmosphere we are not, in any way, releasing CO2 that wasn't already there or while soon be returned there.

>It isn't "clean" it isn't a "solution." It's fine and dandy as better-than-methane but at this point in the game more can kicking isn't what we need.

It is by definition clean and a solution to reduce methane in the atmosphere while cutting fossil emissions at the same time. Not utilizing this would be kicking the can and prolonging the problem. No one is suggesting we do this for every vehicle, I doubt we can fully scale methane capture from waste to run all our energy off of it. But it is a sustainable resource we actually have a net benefit from utilizing and has uses as a niche for applications where batteries just don't get the job done.

And the rate of growth is not equivalant to the rate of consumption. That's the problem. We consistantly undergrow and use other wastes to make up that lack of growth.

Hell, we could easily be growing meat in labs with 0 methane production if we could get over it. Just tell some muscle cells to start growing and cut off a slab whenever you're hungry for some meat. It'll grow back soon enough.

That is the other point. Because of how late this has come, I feel that the resources could have gone elsewhere.

These statements are in contradiction, but if it would have been "clean" 30 years ago it's all clean now. Science doesn't change how it works because time passed.

>And the rate of growth is not equivalant to the rate of consumption. That's the problem. We consistantly undergrow and use other wastes to make up that lack of growth.

Again, an argument for addressing unsustainable farming, which I agree with both crop and animal, but not an argument for not utilizing the methane already being released and putting it to use that also reduces it's warming impact.

>Hell, we could easily be growing meat in labs with 0 methane production if we could get over it. Just tell some muscle cells to start growing and cut off a slab whenever you're hungry for some meat.

While our technology is pushing this capability, it's not that simple or cheap, it also still has to source its composites (including carbon) from somewhere and so there isn't much of a distinction here. It's also not just from cows you know?

The article is about a station that's new, but capturing methane releases from waste isn't, we've been doing that for awhile, so what resources? the methane that's literally better burned than left alone to be released as is? Every gas plant, every converted truck, every ship, running on this is one not adding carbon to the problem.

And the statements are not. This is not clean and should not waste things actually clean (for the atmosphere) resources should get. That does not mean the product should not exist for uses when fuel is needed. Indeed utilize it... But don't call it "clean" and act like it's the end. That is it.

Having a gas station for vehicles specifically is my argument, I suppose. If using it as a fuel is viable, use it in the use cases that absolutely need combustible fuel. Vehicles don't need that.

I've been speaking of vehicle use the entire time. I've been speaking of our production of methane the whole time. Not about naturally ocurring methane. Not of use cases that are outside of a gas station on the side of the road. That's the biggest over-user of combustible fuels. If methane use in areas where combustion is absolutely needed helps? Cool! Not talking about those.

I'm speaking specifically of this application. A fuel station made for vehicles that combust fuel on the road. You are arguing many other points that do not apply. You even stated that that is what the article is discussing. That is what I am discussing. No more. No less. I am not talking about non-anthrogenic carbon emissions.

But we also need to be looking at the root and trying to stop our own methane emissions entirely. Because those vehicles are the end of a chain that need not exist. That is my entire point. This is kicking the can, not cutting our methane emissions which is what needs to happen. Because there are so many natural sources that our anthrogenic production is overloading the system.

That was... Kinda my point. It's what I was talking about from the start.your "why not utilize it" argument is absolutely beside that point when my entire point was to say "this is just exchanging one gas for another in vehicles... It doesn't address the root... It just kicks the can."

I said it was clean because it's byproducts are water and CO2, these aren't toxic pollutants and CO2 emissions are an issue because of introducing new carbon causing an increased greenhouse effect and ocean acidification. This isn't new carbon though it was, and will regardless, remain a part of the environment.

>Science indeed does not change. Conditions do. 20 to 30 years ago, we weren't as poor off in all of our greenhouse issues and this kind of planned can-kicking would have been much more beneficial.

Right but that doesn't change the science on if it's clean or not and I already addressed how not replacing some fossil fuel usage with this sooner is actually can kicking.

>That does not mean the product should not exist for uses when fuel is needed. Having a gas station for vehicles specifically is my argument, I suppose. If using it as a fuel is viable, use it in the use cases that absolutely need combustible fuel. Vehicles don't need that.

Yeah but it's something we can do right now to add to the effort to reduce fossil fuel usage, not in place of other efforts. It dosen't come with the same limitations that batteries do in certain applications, shipping for instance. Largely I agree though batteries are a clear way to go for land vehicles (at least in most applications) and burning it in a power plant would be more efficient.

Ah well, that would be a difference in what we were talking about, because I was talking about capturing and burning methane from waste that would return to the atmosphere if we did nothing anyways.

I agree vehicles aren't the most efficient use of it with some exception and absolutely we should be getting off fossil sourced natural gas as well as every other fossil fuel as fast as possible.

Some disagreement here, that methane would largely exist if more dispersed in nature, this also acts as a or part of cutting those methane emissions by releasing it as the CO2 it came from and would return to anyways. I suppose if we buried and sealed it that would be removing carbon but attempts at that kind of carbon capture have been dubious and as long as we're in a capitalist framework, financially uninspired to pursue in earnest.

>That was... Kinda my point. It's what I was talking about from the start.your "why not utilize it" argument is absolutely beside that point when my entire point was to say "this is just exchanging one gas for another in vehicles."

Yeah I was at no point suggesting we should replace all vehicles with this and that we could scale capturing methane from waste alone for all our energy needs. Regardless of what we could, could not, and should do to reduce the amount of methane in the atmosphere at one time as part of the carbon cycle, we might as well use what's already there especially when doing so just converts it back to what it was and out of a more harmful form faster. Not at all suggesting we try to intentionally make more of it.

Then I think we actually... Mostly agree, and I'm glad we kept up the discussion!

As for that, you're mostly right I think, but that dispersion is important. The greater surface area makes it easier to break down in other ways and keeps it from creating concentrated blankets. A pasture is like sticking a straw in the water and blowing bubbles rather than using a fine aerator. The aerator will get some in solution at least, rather than just jetting gobs of the less dense gas up to the top. Hell, if we had many smaller pastures rather than big industrial ones, that could even help. There are a lot of ways to tackle things that I am in no way qualified to speak on.

My only point really was to say "neat but... Why not just stop producing as much methane? And how can we truly call this 'clean?'

I was in no way trying to say this wasn't beneficial in some way, just that it doesn't address the fact that we're creating too much anthropogenic methane to begin with and that this narrative and the conflation of "clean" with being the perfect solution - especially in marketing - is... Misleading.

Perhaps I am arguing semantics here, but had they even called it "green" rather than "clean" I'd have had less to say. To call it "clean," to most, is to imply that it is the solution, not just an effort. Feels like poorly disguised marketing around something that could otherwise have a decent application with a more transparent understanding.

Yeah we seem to mostly agree, just confusion on the exact thing we were each talking about.

I completely agree with all of that.

And yeah it's also true that fossil fuel companies muddied the word "clean". And nothing is a perfect solution either, we just have several imperfect solutions that can all work together at various scale with a variety of effectiveness and drawbacks.

I'm glad we kept it going too, thanks for the actual discussion instead of the arguing and science denial I've experienced elsewhere on this post. o7

Agree on all points eh? Gee, thanks. :p

But hey, none of us are. We're mostly arguing opinion here. Fact-backed, but opinion. I'm glad we found the disconnect! I find that truly is where "argument" comes about. Most folks wanna agree, just not at the cost of their morals and standards. But we're all flexible too, or should be. Nobody wants what they think is worst it's just the ignorant sorts that wanna stick their head in the sand that cause issues.

But yeah, the perfect world it'd be like the water cycle. Trap the methane, convert it to CO2, plant the food crop, trap the CO2, rinse, and repeat. The problem I see here is just people seeing this and people calling it "clean" and going "so... That's it, right?" when we still have reduction efforts and alternative solutions in other fields and all that to consider. That's all. This one effort just feels like a "no duh, why didn't we do this 20 years ago? Now this effort is too late!

I am glad it helps! I just... don't think it helps enough in this field. And I just don't want to see it turned into a marketing ploy as manipulatable as "carbon offsets" and all that. Just raising a flag, not chaining to the tree. Lol.

And of course, I'd never directly deny science. It is because science says that we are in an emergency state that I hold this very opinion! Passionate and a bit of a tight pull on the rope, if you'll forgive further idiom; but, i live on the west coast of the US and breathing smoke is rather unpleasant. I'd like to see reduction in production ASAP. XD

And to you a cheers on that. I appreciate your passion and for presenting fact and arguing through logically with me. If ever either of our logics could be flawed. We're human, after all, that's why we temper it with fact. My view, at least. But I ramble! Have a wonderful one, stranger-friend. o7

Why do we need less CO2? If you plan to feed the world a vegetarian diet, most crops are at peak productivity around 1000-1300 ppm of CO2. They also use 10-15% less water for that output.

We are currently at 450ppm CO2. Plant death occurs at 150ppm CO2.

Well, if you plan to have humans to feed, turning the planet into a literal greenhouse - the entire reason they are called "greenhouse gasses" - isn't exactly beneficial to those humans. They don't do well in high heat, high CO2 environments.

CO2 traps heat. Less than methane, but for a longer period of time. If you wanna make a super carbonated environment indoors in a real glass greenhouse... By all means. Doing that to the planet is a very, very bad idea for humanity. For many reasons.

Unless you like the idea of acidic, overflowing seas and a return to the paleolithic environment.

Hydrogen is the way to go for the automotive industy and internal combustion engines. The only by-product is water. The only issue is that's it's incredibly expensive to produce liquid hydrogen, and it has a nasty habit of exploding.

Hydrogen has a lot of tough problems to conquer and it may never be a viable energy storage medium. It embrittles components, it tends to leak easily, it's expensive to produce, difficult to transport and store, and so on. It's also not a fuel, it's an energy storage medium so you need to produce the energy to create it in the first place. At that point you might as well put that energy into a medium that doesn't have all the problems that hydrogen has.

There are a few promising methods of using hydrogen to store energy but they are still in the experimental stages and may never get off the ground. For example, you can store hydrogen in metal hydrides or use it to produce ammonia and then release it from those to use as a fuel when you need it. There are still problems to be overcome with these storage methods but they are probably leaps and bounds better than storing hydrogen as a cryogenic liquid or under high pressures.

Indeed, it's a little out of realm for now... But should a breakthrough hit I'm immediately inboard. The most viable stopgap seems to be EV.

I'd love to just see a drop in EV engines. Maybe offer scrap discounts for trading the motor. I think a few are out there, but if it takes off... Hoo!

We need battery exchange stations and easily exchanged batteries at that. Why spend a year charging when you can have 100 in the back and hot-swap them for an exchange and charge a differential fee? If the battery is bad, maybe have a battery recycling fee. There are ways to do it that make sense in the interim!

Drop in EV batteries have been thoroughly explored and the industry has not found them to be viable yet. They are massively heavy and swapping something that weighs well over 1,000lbs cannot be done as quickly as just charging the battery from a fast 480V charger.

Similar for dropping in an EV motor into an existing gas vehicle. That is a massive structural change and by the time you get into replacing the frame, it’s cheaper to get a new vehicle. Sure it can be done in a lab but it is not large scale commercially feasible.

My point was more that we make it feasible. It doesn't have to be all profit all the time when the planet is, in some places, literally on fire because of the changes being brought on.

Indeed it has its barriers and I never said it was a perfect solution either... But if we can find ways to build skyscrapers in weeks, we can find ways to do these things. The problem, as ever, is "profit."

No hydrogen car burns the hydrogen. Theyre using fuel cell, which is full og platinum catalyst and makes electricity from hydrogen-oxygen reaction. The rest of the car is regular electric car.

Also, hydrogen for vehicle use isn't a liquid. Only highly compressed gas. It'd be cryogenic if it was liquid and freeze everything, just like ice forming on space shuttle main tank.
