Could Electric Cars Save the Coal Industry? (msn.com) 165

North Dakota has just 266 electric cars, the fewest of any state in America, reports the Washington Post. But the state's biggest booster for electric cars may be: the coal industry: The thinking is straightforward: More electric cars would mean more of a market for the [lower carbon] lignite coal that produces most of North Dakota's electricity, and if a long-shot project to store carbon emissions in deep underground wells works out, it might even result in cleaner air as well. "EVs will be soaking up electricity," said Jason Bohrer, head of a coal trade group that has launched a statewide campaign to promote electric vehicles and charging stations along North Dakota's vast distances. "So coal power plants, our most resilient and available power plants, can continue to be online...."

In North Dakota, Wyoming, West Virginia — and in the nine other states where coal is the main fuel for electric power plants — electric cars will still rely on the combustion of ancient carbon-based deposits for their energy unless other sources of power come to the fore... [C]oal remains by far the main fuel for power plants worldwide, and a recent surge in its price suggests that demand is not waning. Without an intensive turn to carbon capture — a technically feasible but commercially unproven technology — electric vehicles may not be able to make that much of a difference in the effort to reduce greenhouse gas emissions... [A] carbon capture experiment at the Milton R. Young Generation Station adjacent to the BNI mine, devised by a partnership of scientists and the Minnkota Power Cooperative, could make coal more attractive in the clean-energy future — if it works. The idea, known as Project Tundra, is to scrub the carbon dioxide out of the plant's exhaust smoke, condense it and inject it into deep wells...

Carbon capture has been a popular idea within the coal, oil and gas sectors for years now. The technology is not out of reach. Plenty of pilot projects have been launched. But so far no one has been able to make it a paying proposition. A pioneering $7.5 billion carbon capture power plant in Mississippi was razed with dynamite on Oct. 9 after its owners wrote it off as an 11-year-old economic failure. North Dakota hopes to break through that last barrier, for both coal and oil... If Project Tundra can show that stuffing carbon dioxide back into the earth is economically feasible, he said, "it's opening the door for a CO2 economy. It gives the lignite [coal] industry a way to survive." His group has launched a promotional campaign called Drive Electric North Dakota, which sponsors promotional events, conducts public attitude surveys and lobbies for EVs in the state capital...

Clean-air advocates range from dubious to dismissive. The promise of electric vehicles wasn't that they would spur more coal mining — or oil extraction...

And unproven though it may be, critics contend, the publicity surrounding carbon capture has created a false sense of complacency that world-changing solutions are just around the corner.

The Post also reports that "the oil sector, too, is putting its chips on carbon capture... "

      We don't have the time to waste to develop and scale up this notion of just shoving our pollution under ground

      My impression is that we have run out of time on the emissions side. The Glasgow deal that was just signed is the first time that a global climate agreement explicitly mentioned fossil fuels (which, holy crap), but ignores coal. Even if everybody holds to the agreement, we'll still reach a rise in temperature of 2.4C above preindustrial levels. In reality, it will probably end up being worse than that.

      These are the kinds of temperature increases which will result in half the world's population being regularly exposed to severe heat waves, substantial loss of arable land, a drastic increase in severe droughts, hundreds of millions of people will lose water availability, sea levels will continue to increase, which will result in widespread coastal flooding, and so on. We'll have hundreds of millions of climate refugees, even if we hold to the current agreements. Which we probably won't.

      The thing is that fixing the problem on the emissions side requires everybody to cooperate, and act against their short-term self-interest. Carbon capture does not.

      If we can't find a way to capture carbon, there's pretty much a 100% chance that we're screwed.

          The thing is that, once we have carbon capture technology that is effective and at least somewhat affordable, we only need one country (or very wealthy private entity) to pay for carbon capture, whereas we need dozens of countries to collaborate to reduce emissions effectively. I think it's more likely that we'll find one entity that will pay the cost of carbon capture, rather than getting every relevant country to pay the cost of reducing emissions.

        It also doesn't help that they're greenwashing lignite.

        The thinking is straightforward: More electric cars would mean more of a market for the [lower carbon] lignite coal that produces most of North Dakota's electricity

        Lower carbon content does not mean lower carbon emissions per unit energy generated. Lignite is generally seen as a particularly dirty coal. As is (correctly) summed up at the top of the Wikipedia article on lignite: "The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health"

        Lignite is not low-carbon because it's high-hydrogen; it's low carbon because its high in moisture and ash. These things don't make it burn cleaner and more energetically; they make it burn less cleanly and less energetically. As Wikipedia again (correctly) sums up: Primarily because of latent high moisture content and low energy density of brown coal, carbon dioxide emissions from traditional brown-coal-fired plants are generally much higher per megawatt-hour generated than for comparable black-coal plants, with the world's highest-emitting plant being Australia's Hazelwood Power Station[9] until its closure in March 2017.[10] The operation of traditional brown-coal plants, particularly in combination with strip mining, is politically contentious due to environmental concerns.[11][12]

          Even the .gov link next to the misleading claim that lignite is low carbon explicitly says "Lignite has the lowest energy content of the four [coal] types.".

          Most lignites are also higher in Sulfur (producing acid rain) and burning it results in much higher resulting amounts of fly-ash containing the toxic metals cadmium, copper, chromium, nickel, lead, mercury, titanium, arsenic, and selenium that now have to be managed as well.

        The agreement requires halving of emissions by 2030, which is highly unlikely. 2.7C seems more likely than 1.5C.
      • If we can mobilise our populations & spend trillions on wars, cutting carbon emissions doesn't seem impossible. Until someone comes up with an effective, feasible plan for carbon capture, how about we stop being distracted & work as hard as we can & what can do right now. The coal industry isn't going to save us.
      • The thing is that fixing the problem on the emissions side requires everybody to cooperate, and act against their short-term self-interest. Carbon capture does not.

        The carbon capture discussed here is on the emissions side.

        Carbon capture out of the atmosphere-- where the carbon dioxide conentration is low, at the hundreds of parts per million level-- is a pipe dream.

      We don't have the time to waste to develop and scale up this notion

      The people working on CCS are not the same people working on other solutions to AGW. So CCS is not delaying progress.

      Coal in general, and lignite in particular, is filthy stuff. But the reality is that we will be burning it for many years, so if we can use CCS to mitigate some of the harm, we should do so.

      There are some advantages to CCS in North Dakota. In addition to lignite, ND has plenty of partially depleted shale oil fields. The CO2 from the lignite can be compressed into a supercritical fluid and injected into existing wellheads. The CO2 displaces the remaining oil and forces it upward where it can be recovered. The recovered oil can pay for the cost of CCS.

        It's never been done on a large scale and would be complicated and expensive to retrofit. Is it actually cost-effective compared to filling ND with wind turbines, grid upgrades, and storage and simply not emitting the carbon other than that required for building that infrastructure (which of course needs to be accounted for, as well as not simply being divvied out over 50 years of production from windmills as it matters if there's a 'burp' from construction now, although CCS also needs construction).

        That only happens in dreams.
        In reality the very first thing that will be done once carbon capture becomes viable is the building of new coal power plants until the total CO2 output succeeds current levels. It's unavoidable unless coal is severely limited or even banned by regulations.

          Even with perfect carbon capture coal won't come back. Dirty coal is more expensive than wind, solar and natural gas. The fight is now between on shore wind and natural gas for electricity generation with off shore wind and solar following very closely behind. Just a matter of time before wind and solar overtake natural gas too. At that point it will be more expensive to burn fossil fuels and it will naturally come to an end.

          All people depending on fossil fuel industry for a meal ticket will be in trouble. But the economy will be expanding all those with portable skills will move on. Owners of stranded assets, workers who are not in a position to move on will be very bitter. The climate agreements and all the green tech will be politicized for their votes.

          I have no sympathy for the owners. But we can take care of the workers. There are just 50,000 coal workers left in America. We need their skill to properly close the mines safely, to stop mine subsidence, to stop random soccer teams from getting stranded deep inside etc.

          TL; DR = Coal is not coming back. I would support government taking care of workers with stranded skillsets due to the transition. Let the owners win and lose money by the rules of freemarket.

            I agree with you on a somewhat longer time frame. But i'm afraid that in the coming few decades coal will in many cases be seen as a viable option.
            In any case, i was talking about the dynamics of carbon capture and coal production, specifically whether carbon capture will reduce the CO2 output of burning coal.
            I don't think it will as history shows that any such improvements only lead to more careless use of whatever it is we have improved. Cars, for instance, have become much more efficient over the years,

        Most fridges have a power management which switches them off regularly to melt off ice sheets and thus increase the effectiveness of cooling. So fridges don't need to be switched on 24/7. Power needs during the night are so much lower that for a century, utilities urgently searched for possible consumers of superfluous electric energy, as storage was not feasible for the large amount generated, and switching off power stations and starting them again when demand increases in the morning is really expensive.

          Ice can get down to well below the freezing temperature of water, it's while it's forming that it consumes energy and interferes with the cooling process. Preventing moisture intrusion is the job of the door seal. Frost-free freezers actually have heated door sealing surfaces (and possibly other heated surfaces) and they go through a frost melting phase in order to prevent the doors getting frozen shut. If you catch them in the heating phase you can actually feel the warmth around the seal area. If you keep

Solar at best is a neat little trick to flatten peak demand during the day unless of course things are not in perfect alignment in which case it will do zip. At least wind has a chance of working most of the day and year, solar is by default useless roughly 50% of the time, and that's not even including bad weather conditions.

    Well, sure, coal is a finite resource. Estimates vary wildly as to how much is left - it could be as high as 100 years more supply, but the price will continue to rise, as it gets more complicated and expensive to extract it.
    Another 100 years of coal used at scale, is game over. Heck, 30 years is game over for civilisation as we know it today. We end up over 2.5c by the end of the century.

    The coal industry needs to be phased out as quickly as possible. The more we dither and delay with ideas of carbon capture, the longer it will persist.

    These ideas are simply those of an industry under threat and we all know they'll present the idea and just keep on kicking the can down the road in terms of capturing that carbon at a scale that is affordable and prevents further global heating. It isn't going to happen.

    Renewables are the future - and that absolutely includes nuclear power as a transitional "fix" whilst we work on better ways to harness safer renewable energy.

    The more we screw around with "work-arounds" for coal, the less time there is to replace it with that renewable mix (including nuclear.)

    As part of the change, jobs and livelihoods need to be considered. The coal industry employs a huge amount of people. The transition needs to include them.

    • The coal industry has been upscaling & automating much of its extraction technologies, e.g. mountain top removal, & over the past few decades has been shedding far more jobs than it's been creating. Additionally, working conditions & their health & safety records make coal mining & particularly undesirable career to go into. Coal's becoming economically untenable anyway, all it has left in sunk costs & enertia. Put it out of its misery & by all means help those coal mine communit
    • The coal industry employs a huge amount of people.

      The coal industry in the US employs fewer people than Arby's. Arby's comes in at #15 in rankings of fast food restaurants [qsrmagazine.com].

Because the local political leaders spent the last few decades claiming they'd bring coal jobs back instead of building up replacement industries.

Just because you lead a very privileged life doesn't mean it is even close to being reality everywhere else. In fact, to the average person, you sound like you're smoking something.

            You're not wrong, but you're also not right overall. It's not a surprise that new technologies come to the wealthy first. It would in fact be a surprise if they didn't. However, when the GP says "The fact is the price of solar panels is falling rapidly and like BEVs will become more affordable for the average person in time." they are absolutely correct on both counts.

        If you can afford it you won't regret it. I have both and I am very happy with it. The catch is the cost is still reasonably high so the ROI is several years. The good news is it is rapidly becoming more affordable so if you can't afford it now the odds are you will be able to with in a few years. I would certainly not by a new ICEV now, If a BEV is too pricey for you now I would suggest buying a good second hand ICEV that has already depreciated and use that until a BEV reaches your price point.

    • 5kW is a pretty slow charge --- 12 hours for a 60kWh battery (which is pretty common). And, you know, during the day --- one of the nifty advantages of BEVs is you can charge overnight while you're sleeping, which doesn't work for solar without a big house battery. With just the 5kW of solar panels and no battery, that could mean only being able to drive every other day.

        I'm having difficulty reconciling the first & last sentences in your comment. Which is it, safe or unsafe?

        You had trouble because you ignored the next to last sentence. Also, there are different kinds of safety. There's the kind where it's unlikely to spontaneously combust, and there's the kind where it's okay to emit the byproducts into the atmosphere. Coal and oil (and even refined diesel fuel) have the first kind but not the second. And then there's the kind where it's safe (or not) to produce it.

        • "Safe to emit..." - You know that close proximity to oil, diesel, & petrol is hazardous to people's health, right? And you do know that petrol cars also spontaneously combust, right? Where does that leave "relatively safe" in terms of health & safety?

  • That's an interesting way to spin lower amount of energy yield per waste produced.

    Even a woodland bumpkin should know that you get more heat out of the same mass/volume of dry wood than if you burn wet wood, which is why it's not a bad idea to let the wood dry for about 2 years before you use it. If your firewood is dry then the amount of wood-tar produced will be a lot lower as well, reducing one potential and difficult to see fire-hazard in your chimney, and thus requiring less maintenance for the firep
    • You get higher temperatures because the heat isn't going into changing the state of water, but you get the same amount of heat energy out. When the cresote forms on your chimney that heat energy is going into the pipe and then presumably into your room. Most people only have a short stovepipe to radiate so they need a high delta T in order to get effective heating of the room. But does any of that matter in the case of steam generation?

      My take on it is conservation. What if we find a use for that coal later

      • by fazig ( 2909523 )
        The energy density depends on how you measure.
        If you measure the total mass then dry wood does have a higher energy density, because less of the mass is wasted on the inert water. Energy density can be improved further by turning wood into charcoal and charcoal into coke. Of course every step involves a lot more work.

        This is also not a new principle as it was already known in the times of steam engines, where they preferred the high energy density bituminous coal for train engines over anything else.

Storage for the off periods is hard, expensive infrastructure needs to run 24/4 to be economic, you can't run a smelter for 6 hours a day and still make a profit.

    1) It is a solid, so we can't pipe it anywhere. We have to truck or rail it. So we burn gasoline to move coal. Incredibly stupid. (Note movement by sail ship is the cheaper than pipeline if the coal is at the shore and the coal plant is also at the shore. Only time pipeline is not the cheapest way to move stuff.)

    2) It is also old and found underground. So heavy impurities seep into it and get released when we burn it. The main ones we care about are Mercury and radioactive materials. Lead as well. No other fuel that we burn has these in quantity.

    3) It has no Hydrogen, just carbon and impurities. Hydrogen burns into water. Carbon burns into carbon monoxide and carbon dioxide. One is a deadly poison, the other a major green house gas. All other fuel has Hydrogen, so it is better.

    4) Coal processing is far more dangerous (both immediate and long term risk of cancer) than any other fuel extraction. You are more likely to die from radioactive poisoning if you are a coal miner than a Uranium miner.

    Coal is just about the single worst way to get energy that anyone has ever thought of, unless you care about whales, then whale oil is the worst and coal is 2nd worst.

    • 3) It has no Hydrogen

      27% of hydrogen produced commercially comes from coal. [coalage.com] (According to the coal industry. Other article say more like 18%)

      Hydrogen is the second-most prevalent element in coal, after carbon.

  • This is the only way this can work. Coal is barely economically competitive, but it becomes largely uncompetitive once carbon sequestration is accounted for. So, at the end, this isn't a win for these states, but the usual bailout for an uncompetitive form of energy generation. Might just as well subsidize horses as a "sustainable" form of transportation.
  • North Dakota charges a $120 road use fee for EV registrants since they cannot collect it with the gas tax.

    I primarily charge at home, which is coal-power.

    Every day you can see BNSF rail trains running through the state carrying coal.

    Solar panels don't work as well in North Dakota due to the weather (snow and ice covering them, hail, tornadoes, destroying them), and you have to own them 7-15 years to get a return on investment. During that time, you've had one of the weather-induced failures happen.
