        It’s only fine until those sulfates react with water vapor in the atmosphere to form sulphuric acid. That stuff rains back down and contributes to ocean acidification which is causing serious harm to all sorts of marine ecosystems.

        This is wrong in some many ways. To add to the already mentioned. Ocean water is the largest carbon dioxide buffer by absorbing CO2 to become carbonic acid. As the sulfur acidifies the Ocean, this “competes” with the carbonic acid, increasing the CO2 emissions from the Ocean.

        In other words, all geoengineering tropes end up being horseshit.

        Also, the cooling effect sulphate aerosols can cause only really happens at high altitudes. At low altitudes the reflected light is less likely to escape to space, and the aerosols fall out of the air faster.

        Even if they reached high altitudes, one of the effects of being in the atmosphere is moving with the wind, across entire hemispheres. And at tropospheric heights, sulphates, their products, and other byproducts of combustion may destroy ozone at significant levels.

        There may come a day where aerosol-based geo-engineering becomes a part of climate management, but it’s definitely not with bunker fumes.

    Some of these ships would carry green hydrogen and new lithium batteries and old lithium batteries (to be recycled) and whatnot. Also at least some oil would be still needed for fine chemicals like meds or (idk what’s proper english term for that) large scale organic synthesis like plastics, or even straight distillates like hexane (for edible oil extraction) or lubricants. Some of usual non-energy uses of oil can be easily substituted with enough energy like with nitrogen fertilizers but some can’t

      We aren’t consuming batteries anywhere near the rate we consume oil and coal. Hydrogen even less than batteries.

            Yeah, there’s no reason to be transporting hydrogen long distances. You can make it anywhere that has water and electricity. And if you’ve transitioned to a hydrogen based economy (which is a big if), ships wouldn’t run on oil any more anyway, so there’s no problem there.

              there absolutely is? What if i can buy hydrogen at 1$ per ton, from the hydrogen production empire, meanwhile in the manufacturing empire hydrogen is produced at 2$ per ton. Economically, it would make sense to buy that hydrogen from the hydrogen production empire.

              It’s not going to be as significant as a trade as something like coal and LNG obviously, but the market IS going to do this in some capacity. And it’s a beneficial thing for everybody.

                  obviously not, and that’s mostly going to be military contracts more than anything.

              Yeah but your electricity also needs to be produced by reusable manners, which commonly results in solar power. And since the intensity of solar rays and the amount of sunny hours per day vary on the global scale there are some countries which are capable of producing more hydrogen and cheaper than producing locally. I know that the German government is looking at Marocco to establish a hydrogen production and import.

            you really think this is going to stop the globalism aspect from happening? If you can ship something, and get better market rates on it, you’re going to do it. Economics follows the cheapest route, not the most efficient.

            It also just makes sense if you think about it. Places like alaska are going to struggle to generate green energy compared to another place like, texas for example. If you can ship in green hydrogen much cheaper than you can locally produce energy, why wouldn’t you? It’s a reasonable solution to the problem of supply and demand scaling.

                last i checked industry is the primary energy consumer. Sure there’s less people in alaska, but it was just an example i picked, and the market economics would still be applicable there. If it’s cheaper to buy hydrogen, than it is to produce locally sourced power, that’s going to be what happens.

            no we can’t make hydrogen everywhere, there will be regions with large excess of renewable energy compared to population. these places could export hydrogen. you also don’t need a lot of transport if crude is extracted near place where it’s used, like for example heavy crude from alberta

              The problem with the comparison is hydrocarbons are the energy source, hydrogen is no it’s just the energy carrier. It is very inefficient to convert energy to hydrogen then convert it back again. Something like 60% round trip efficiency. Not to mention the cost and loss in loading into containers and shipping it around the world. It’s also not a very dense fuel per volume especially compared to oil. It’s just way easier and cheaper to have cables that run from one place to another. They are already building one from Australia to Singapore and if it’s successful that will probably open the floodgates. There aren’t many places that are more than 2000 miles away from large sources of renewable energy even if your thinking places like Alaska which could do hydro if there ever was dense enough populations anywhere that would consume it.

            That implies that we can make electricity everywhere, which is technically true but not really the case because there’s countries with more and with less free space, with more suitable places and less suitable places to put renewables.

        There’s alternative processes, and if you avoid burning oil and coal for fuel you can basically do all that with the amount of oil that’s in easy reach instead of using tar sands or drilling into even more difficult to reach places.

          You have to be careful when talking about steel because coal is both an ingredient (steel is iron + carbon) and used for heating afaik. You can take coal out of the heating step (confusingly called steel making) but not out of the ingredient step, unless you want to find a different carbon source.

            There’s (admittedly comparatively expensive) alternative processes, and even if you stick to the old process and just stop using coal for electricity generation you’d cut coal use by 75%.

            Not to mention, the carbon that stays in the steel doesn’t actually go into the atmosphere, so there’s less CO2 emissions for that specific use if you can substitute the fuel used for heating.

            you’re probably talking about direct reduced iron and it’s really a problem that can be dealt with easily, just chuck a piece of coke when it’s molten for the second time in electric arc furnace (and maybe electrodes introduce enough carbon). substituting coke with hydrogen works also on “ingredient step” if you mean by that fuel needed to reduce iron ore to iron

            maybe there’s a way to make electrowinning iron economical, and it’d be pretty green too, but i don’t know if it is workable

            e: you can also avoid need for met coal if you use methane or syngas for direct reduced iron process

          the problem with tar sands is a fundamental energy conversion issue. It’s really hard to refine because you don’t get nearly as much energy out as you put in, compared to something like fracking.

          It may become reasonable in the future with really cheap renewable energy and higher oil prices for example, but as of right now, it’s economically unviable.

        Everything that comes out of a petrochemical plant can be made without oil, in fact BASF had recipes in place for decades now and is switching sources as the price shifts. Push come to shove they can produce everything from starch. It’s also why they hardly blinked when Russia turned off the gas.

        The carbon that actually ends up in steel is a quite negligible amount (usually under 1%, over 2% you get cast iron), you can get that out of the local forest, and to reduce the iron hydrogen works perfectly, the first furnances are already online.

          Water/wind/solar is cheaper now, and it’s not even close. It’s electrifying communities that never had any sort of electrification before since they can buy a few panels and bypass the (often corrupt) power utility in the country. The intermittency is a problem, but it’s still better than not having it at all.

          So yes, it looks like they’ll skip carbon-based energy entirely. This is similar to what’s happened with landlines in these regions; they skipped straight to cell phones.

    Fun fact: through the 1800s coal-powered steamships mostly replaced sailing vessels for the transportation of people and time-sensitive cargo around the world. But steamships were highly inefficient and required frequent re-coaling, and locally available coal was dirtier and contained less thermal energy than the good stuff that Britain (who was doing by far most of the shipping) got from Wales and other places on their island. Because steamships could not efficiently and cheaply haul the coal that they needed around the world to restock the coaling stations, this was done instead by an enormous fleet of sailing colliers. So the “steam revolution” of the 1800s was actually a steam/wind-power hybrid. It wasn’t until the advent of triple- and quadruple-expansion steam engines, turbines, and greatly improved boilers in the early 1900s that steam-powered vessels could efficiently and economically haul their own fuel. And even with that, wind-powered cargo vessels remained economically viable and operating in significant numbers right up until the start of WWII (that’s II, not I).

    A great read is The Last Grain Race by Eric Newby, about his time as a sailor aboard Moshulu (a large steel sail-powered cargo ship) in 1938-1939. Moshulu went on to star in The Godfather Part II as the ship which brings young Vito Corleone to New York, and is now weirdly enough a floating restaurant in my city of Philadelphia (I’ve never eaten there but I want to).

      Offhand I believe we have a few that can do light oil, but most of ours wouldn’t want to change over even if offered to do so for free. Rather the reason is the US has a lot of chemical engineers and capital and so is good at refining the more challenging to deal with and cheaper to get heavy oils while selling the easy to refine and therefore more valuable light oil we dig up down in Texas to places that have more primitive refineries.

      While we could retrofit all of our our refining capacity to use our oil, it doesn’t make financial sense because your spending a lot of money to switch to an more expensive input, so companies arn’t going to want to do it unless the government forces them to, and the government would only force them to if it wanted to spite everyone else and raise domestic gas prices.

            dude. we are not talking about the gasoline. we are talking about the oil being used to make the gasoline. what percentage of the crude oil being refined into American gasoline is American produced crude oil?

      actually, it’s already happening, why do you think LNG is such a massive export from the US right now?

    Yeah but if I’m not mistaken, emissions from shipping are quite low anyways. It’s something like 2-5℅ of all our emissions, so it’s pretty low priority.

        Yeah but my point was moreso that there are more important things to focus on that are probably easier to do. I mean, reducing shipping by just the fact you don’t need to ship oil anymore is pretty nice, it’s free reduced emissions, I’m just saying that it’s not that big of a deal. It is a nice plus however.

      all freight traffic is a pretty significant dent, i think the net total for all of transport is something like 15-20% of total emissions, so.

    to be perfectly clear, this probably wouldn’t help much, since we would likely just move to shipping something like hydrogen across the ocean anyway…

      Hydrogen is just worse natural gas. They crack natural gas to produce hydrogen, and its fucking terrible. Hydrogen creates about 4 times more CO2 than diesel, simply by how the vast majority of it is manufactured

        Hydrogen isn’t about energy production, it’s about storage

          Yes, a potential future application, in a system where we basically always have more renewable electricity than we can use could see some great hydrogen-based storage in hydrogen.

          But that’s not the world we live in today.
