China Successfully Mines Gas From Methane Hydrate In Production Run (oilprice.com)

hackingbear writes from a report via OilPrice.com: In a world's first, China has successfully extracted gas from gas hydrates in production run in the northern part of the South China Sea. According to the U.S. Department of Energy (DOE), global estimates vary, but the energy content of methane in hydrates, also known as "fire ice" or "flammable ice," is "immense, possibly exceeding the combined energy content of all other known fossil fuels." But no methane production other than small-scale field experiments has been documented so far. The China Geographical Survey said that it managed to collect samples from the Shenhu area in the South China Sea in a test that started last Wednesday. Every day some 16,000 cubic meters (565,000 cubic feet) of gas, almost all of which was methane, were extracted from the test field, exceeding goals for production mining. This is expected to help cut down China's coal-induced pollution greatly and reduce reliance on politically sensitive petroleum imports controlled by the US. "The production of gas hydrate will play a significant role in upgrading China's energy mixture and securing its energy security," Minister of Land and Resources Jiang Daming said on Thursday.

      Natural gas hydrate consists of methane locked in water crystals that also are called flammable ice. It is an enormous untapped energy source formed under high pressure and low temperatures in permafrost or under the sea. It is regarded as a clean energy option with high energy density and huge amounts of reserves. It releases less than half the amount of carbon dioxide when burned as do oil and coal, ministry officials said.

      It releases a lot less carbon than their existing coal fired plants and shit load less particulates, so a big improvement in that regard.

      From what I've read on the Methane (CH4) vs. CO2, it's not at all clear cut. CH4 is indeed a far worse greenhouse gas than CO2 - figures of 20-30x the heat trapping potential are often mentioned - but lingers in the atmosphere for a much shorter span of time than CO2 as natural processes tend to remove it within a decade or so. An additional problem is that those natural processes might be in the process of being overwhelmed by the sheer amount of CH4 being introduced into the atmosphere, both from natural sources (about a third of the total) and human sources like transportation and intensive livestock farming.

      Getting back to the question at hand, whether it's better for the environment to burn the CH4 vs. something else, you'd need to take into account exactly what is getting released into the atmosphere for a given amount of energy output. There are already technologies in place to limit CO2 emissions from coal-fired power plants, so if it's possible to do something similar for burning CH4, then there's no reason why it wouldn't be a much cleaner source of power than coal, GWh for GWh.

    Methane released unburned by itself, not only turns the world's temperature up. It does it on steroids! Burning methane does add carbon to the atmosphere; but it's a closed loop. (Every full grown tree absorbs 40 LBS of carbon a year.) Since the ice is going to melt anyways because of our stupidity with fossil fuels. Taking the burning option will slow things down. Because if we don't the ice will melt under the polar caps and be released in one big burp - jumping the world average temperature level to heights never perceived!!

    True, the planet will probably survive, but human society isn't quite so resilient. Rising ocean levels will displace billions (40% of the population live within 37 miles of a coastline), changing weather patterns will disrupt an already strained agricultural system & conflict over resources will further add to the "fun". Though would also say that there is still a chance of us completely destroying the planet, as humans are inconceivably stupid when it comes to survival. If you had a room with just enough food for 5 people to survive until rescue but a group of 20, instead of coming up with a clear, fair system of choosing those survivors and abiding by that choice those people would fight over those resources, likely destroying or wasting the resources in the process so that few if any people survived. On a planetary scale I can easily see as the situation becomes more dire humans literally eating/burning everything in sight in a vain attempt to survive. Eventually trashing the biosphere so badly that recover would take a long time if at all.

    Okay I'll bite.

    If someone tells your that we are running out of (insert fossil fuel here), what they are most likely talking about is economically viable (insert fossil fuel here) not absolute values. This planet has a ton of trapped energy, it's just ridiculous to think of the sheer amount of energy that has been stored in this planet over it's billions of years of existence. It's a ton of flipping energy and unless something significantly changes about how human's exist, there's just no hope in us ever extracting 100% of all of that energy from the planet, ever. Put bluntly, we will never ever reach a point where humans have extracted absolutely every single bit of energy stored in this planet. Be it coal, oil, natural gas, or whatever else, there's just simply too much of it that we'll never get *all* of it. There is a limited supply of economically viable fossil fuels. We are indeed getting more creative with things like fracking (invented in 2006) that's helped us extend our reach. But at some point even that too will not be enough and we will need another innovation to extend our reach further. Some industries, just haven't had any of those *break through* innovations and it really makes you wonder about their economic viability. We're pretty good as a species at innovating so we're going to always come up with new and interesting ways to extract energy form the planet. The question is less, will we be able to extract the energy and more will there be any buyers? If this technology can be made to be cheap and reliable, then China's sitting on gold here. If it's only going to save them a buck or two,
    then they'll just sit on the technology until energy prices in the other industries go up enough to make this gold. If it's never going to save them money, then this might very well be the last time we all hear about it. But again, it all comes down to less about how awesome we can innovate and more so to market pressures.

    The doomsday scenarios, unless you're talking about climate change which is a different topic altogether, is basically what happens if we run into a period of time where we've not yet hit the next innovation and energy prices are flying through the roof? It's not unrealistic to think that we might be in the middle of researching the next big thing and then poof (and by poof I mean over the course of several years), we're running low on X-Y-Z fuel that we can extract at $5 a unit. We've got at least ten years of X-Y-Z fuel but we extracted it at $23 a unit and we've got at least three decades worth of X-Y-Z fuel but it was extracted at $78 a unit. That's a doomsday scenario. If we don't find a way to get that $23/unit X-Y-Z fuel somewhere close to $5/unit X-Y-Z fuel, a lot of industries that rely on X-Y-Z are going to be hurting. Heaven forbid we have to tap into that $78/unit fuel. We have technically forty years worth of fuel but all at prices that either no one will want to pay, or at prices that will drastically change industries. Sometimes governments subsidize things to help get the price as close to something that will keep demand up, but that can only go so far. The point being, there's no physical shortage, we're not absolutely out of X-Y-Z, but we are running out of X-Y-Z that the majority of people will pay for.

    Absolute terms are silly to talk about. I think in the Asia-Pacific there's like enough coal to keep everyone in Japan, China, etc warm till 4000 or 5000 AD. But the majority of it is impure and would require an insane amount of processing before it actually became "fuel" grade coal. That's not also mentioning that a lot of it is difficult to get to, being trapped in complicated geological structures are aren't exactly the easiest thing to just drill through and have a stable tunnel running through it. Those are obviously things that eventually we'll have technical solutions for, but not right now. Also, if anyone wants to talk absolute terms. The sun is the way to go. It's got enough energy to power us for the next billio

    If that were a conventional gas well onshore, it would be pretty marginal for commercial viability - it would all depend on the availability of infrastructure to get it to market. For a well in deep water (it must be deep to have a low enough seabed temperature for methane hydrates to be stable), it would be an economic failure, because of those self-same infrastructure costs.

    This is expected to help cut down China's coal-induced pollution greatly

    This one project, no. If scaled up a lot (10^5 if not more), it might be significant. Which will take a considerable period of time because of the need to build that infrastructure. There are only so many deep water pipelay barges in the world.
