    Solar/wind + battery storage is cheaper than natural gas and a hell of a lot cleaner. It makes no sense to go for a more expensive, dirtier form of energy.

      there’s not enough lithium on this planet to store enough energy for like half of europe nevermind entire world

      you know how to do this the right way? use pumped-storage hydropower. need more? build more, then dump power into heaters (or better yet heat pumps) on demand from grid since fossil fuel heating will be replaced anyway. (we’re nowhere close to this, but it can sink a lot of energy quickly while not using it at some other times)

        Pumped hydro is both very geologically limited and environmentally detrimental. That technology alone will not substantially reduce the need for other power storage technologies/ peaker plants.

          Pumped hydro is both very geologically limited and environmentally detrimental.

          If you are willing to live with the very considerable impact and are willing to do a costly megaproject, one possibility that I’ve raised before: it’d be possible to go implement Atlantropa, but instead of using it (exclusively) to generate hydroelectric power, as its creator envisioned, use it for pumped storage. The world will never need more energy storage than that could provide.

          https://en.wikipedia.org/wiki/Atlantropa

          Atlantropa, also referred to as Panropa,[1] was a gigantic engineering and colonisation idea that German architect Herman Sörgel devised in the 1920s, and promoted until his death in 1952.[2][3] The proposal included several hydroelectric dams at key points on the Mediterranean Sea, such as the Strait of Gibraltar and the Bosporus, to cause a sea level drop and reclaim land.

          The central feature of the Atlantropa proposal was to build a hydroelectric dam across the Strait of Gibraltar, which would have generated enormous amounts of hydroelectricity[4] and would have led to the lowering of the surface of the Mediterranean Sea by as much as 200 metres (660 ft), opening up large new areas of land for settlement, such as in the Adriatic Sea. Four other major dams were also proposed:[5][6][7]

          • Across the Dardanelles to hold back the Black Sea
          • Between Sicily and Tunisia to provide a roadway and to lower the inner Mediterranean further
          • On the Congo River below its Kasai River tributary, to refill the Chad basin around Lake Chad, provide fresh water to irrigate the Sahara, and create a shipping lane to the interior of Africa
          • Extending the Suez Canal and locks to maintain connection with the Red Sea

          Sörgel saw his scheme, which was projected to take more than a century, as a peaceful pan-European alternative to the Lebensraum concepts that later became one of the stated reasons for Nazi Germany’s conquest of new territories. He envisioned Atlantropa as a way of providing land, food, employment, electric power, and, most of all, a new vision for Europe and neighbouring Africa.

          There are two very considerable issues there:

          • First, dropping the Mediterranean Sea by 200 meters is going to have a very large impact on the coasts of northern Africa and southern Europe. Sörgel considered that desirable, but obviously there are going to be a lot of people who don’t like such a change.

          • Second, if it’s permitted to build structures in this new area – as was originally intended – then a rupture of the dams would produce cataclysmic flooding; we would essentially have recreated the Zanclean flood:

            Ninety percent of the Mediterranean Basin flooding occurred abruptly during a period estimated to have been between several months and two years, following low water discharges that could have lasted for several thousand years.[3] Sea level rise in the basin may have reached rates at times greater than ten metres per day (thirty feet per day). Based on the erosion features preserved until modern times under the Pliocene sediment, Garcia-Castellanos et al. estimate that water rushed down a drop of more than 1,000 metres (3,000 ft) with a maximum discharge of about 100 million cubic metres per second (3.5 billion cubic feet per second), about 1,000 times that of the present-day Amazon River.

            The Royal Air Force bombed two dams in Germany during World War 2 to flood an industrial area in Germany. Russia just blew up a hydroelectric dam in Ukraine that caused a mess and water to drop upstream by 2 meters. If such a dam were to be attacked in a war like that, it would be horrendous. We’d be talking about a water depth difference a hundred times that and a far larger area.

          EDIT: And a third, I suppose – if you take water out of the Mediterranean via evaporation and pumping, it will eventually wind up elsewhere, and we live in an era where sea level rise is already a concern, so it’ll cause sea level rise elsewhere. Would eliminate concerns about sea level rise for the Mediterranean, though…

            There is also the issue that if building nuclear plants takes too long and is too expensive to be the solution, then such a project would also be too late to matter. Also transmission losses likely mean this is a solution for much less of the world population than you think. If we had a truly global lossless grid, then we would need much less energy storage to begin with.

            Impracticalities aside, absurd geoengineering what-ifs are entertaining. Thanks for sharing.

      How exactly is the production of batteries cleaner and cheaper than the production of natural gas?

        Mostly because natural gas is a one and done thing when it is used. Batteries can be recycled. Production of natural gas is largely done through racking which destroys the groundwater. While batteries often require mining (excluding mechanical ones), they often can be broken down and reused in new batteries. And of course there is the greenhouse gas emissions from methane that are horrible. Methane is extremely leaky. Methane usage emits about as much greenhouse gas emissions as coal does.

        In the US, the major source of natgas is now fracking.

        And uh, fracking is about the most gross extraction method for anything you can dig out of the ground.

            Typically not by injecting toxic carcinogens into the ground to do so, like we do with fracking.

            Also I’ve not heard of any strip mining activities that turn a town’s only water supply into something that’s flammable, but I perhaps missed that?

            Or the ongoing incidents of child and adult cancer caused by this itty bitty little toxic waste issue.

              No need to flat out lie in order to make a point.

              Unless you want to honestly double down on the “I am so ignorant that I honestly believe mines do not contaminate surrounding areas” card you should take off for the day, rest up, and try again tomorrow bud.

                  Not your friend for one. For the other, I don’t need to “bring the receipts” to demonstrate that mining and battery production is not good for the environment.

                  Anyone who needs that is too mentally feeble to be a part of this discussion and should recuse themselves for their own safety.

          Do you want the math or would you prefer less reading and more pictures?

          Nothing like an ignoramus to try and make someone else feel stupid for asking a question.

          Since you are all knowing, explain to me exactly how deep earth mining is less costly and better for the environment than deep earth drilling.

          Or did you think we just magically pull batteries from thin air at 0 cost?

            Easy, just compare the amount of pollution required to make a battery and a solar panel with the amount of pollution required to extract and burn fossil fuels for the equivalent power output over the duration of the renewable’s working lifetime.

            Oh, and don’t forget. Fossil fuels are useless without an engine to burn them, so you need to account for those infrastructure costs as well.

        You make the batteries once, and the pollution due to production is spread over the 10-15 year lifetime of the battery. During that time gigawatt hours of clean power sloshes in and out of them. This in contrast to having to produce enough gas to make all of those gigawatt hours once, then throw the gas away as co2 and get more, along with the attendant pollution.

          Batteries have infinite energy now? No storage issues due to electrical surges, heat, cold, or anything else that makes batteries sub optimal? While seemingly by magic, mining rare earth minerals spreads its environmental impact over 10-15 years of the lifetime of the battery with 0 negative impact to the area the mine is located?

          Oh wait… None of that is true so I guess you can try again.

            I have no idea what you are trying to say. Batteries have an environmental impact, but so does fracking for natural gas. You have the impact up front making a battery, but charging it with renewables does not have continued environmental impact. But if you use gas, you’re going to have to use an awful lot of it over that time period to offset the clean power you’re able to use when you have a battery. And that gas has a very high environmental impact, continually, over that entire time period.

            I didn’t say batteries have NO impact, but they have less impact than continually mining and burning fossil fuels.

              It really is too bad about the weak life cycle, poor charge/discharge rate, and incredibly low voltage that begin the story of “Why don’t we just use sodium ion batteries?” and place it directly in the “tragedy” section of the book store.

                    Once. They are pulled from the ground once. After which they are essentially infinitely recyclable.

                    Oil/gas is extracted then used a single time and it’s gone.
