Imagining an All-Renewable Grid With No Blackouts Without Long-Duration Batteries (stanford.edu) 227

Posted by EditorDavid from the going-green dept.
Slashdot reader SoftwareArtist shares an announcement from a Stanford University institute for environmental studies. "For some, visions of a future powered by clean, renewable energy are clouded by fears of blackouts driven by intermittent electricity supplies," the announcement begins.

"Those fears are misplaced, according to a new Stanford University study that analyzes grid stability under multiple scenarios in which wind, water and solar energy resources power 100% of U.S. energy needs for all purposes." "This study is the first to examine grid stability in all U.S. grid regions and many individual states after electrifying all energy and providing the electricity with only energy that is both clean and renewable," said study lead author Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford... Imagine all cars and trucks were powered with electric motors or hydrogen fuel cells, electric heat pumps replaced gas furnaces and water heaters and wind turbines and solar panels replaced coal and natural gas power plants. The study envisions those and many more transitions in place across the electricity, transportation, buildings and industrial sectors in the years 2050 and 2051...

Interconnecting larger and larger geographic regions made power supply smoother and costs lower because it upped the chances of available wind, sun and hydro power availability and reduced the need for extra wind turbines, solar panels and batteries. A significant finding of the study was that long-duration batteries were neither needed nor helpful for keeping the grid stable. Instead, grid stability could be obtained by linking together currently available batteries with storage durations of four hours or less. Linking together short-duration batteries can provide long-term storage when they are used in succession. They can also be discharged simultaneously to meet heavy peaks in demand for short periods. In other words, short-duration batteries can be used for both big peaks in demand for short periods and lower peaks for a long period or anything in-between.
Other findings:
  • Cleaner air would spare about 53,200 people from pollution-related deaths every year. It would also spare millions more from pollution-related illnesses. Total estimated health costs saved each year: $700 billion.
  • Building and operating a completely renewable grid may create 4.7 million long-term jobs.
  • Per capita household energy costs were nearly 63% less.
  • New electricity generators would occupy about 0.84% of U.S. land (versus roughly 1.3% occupied today by the fossil fuel industry).

      One place it comes from is not paying for the actual fuel or displosal of nuclear waste and so on which the current grid requires. Also, if the energy becomes cheaper since renewables are much cheaper, many more industries such as synthetic fuel product or farming under synthetic light become viable which wouldn't otherwise exist and so new jobs are created elsewhere as well.

      • Eliminating "costs" associated with waste disposal (etc.) means cutting jobs related to those things. All costs are, at some point, labor costs even if it's not immediately obvious. The only way to add total jobs without increasing burden on the consumer (or taxpayer) is to reduce the pay for each job.
        • ...or increase productivity per employer, which is what modern renewable sources may enable.

          • ...or increase productivity

            "Increasing productivity" is the OPPOSITE of "creating more jobs".

            Productivity is defined as the value produced divided by the hours of labor to produce it.

            So if renewables "create jobs" (more labor) to produce the same energy output, then they lower productivity.

            • Electrified future requires much more electricity generated than is being generated today. Hence there's no prospect of "the same energy output". Hence your argument is irrelevant.

              • Electrified future requires much more electricity generated than is being generated today.

                Electrification of cars requires only 20% more power and charging is variable demand that can fill troughs in current demand. So we will have better use of existing infrastructure rather than needing new capacity.

                Switching from gas furnaces to ground-loop heat pumps cuts energy use since the heat pumps are more efficient. So job losses in the gas industry will be greater than new jobs in green energy.

                • Those things are true. They still don't disprove what I said. Notice how you for example ignored hydrogen production for chemistry, agriculture, or metallurgy.

              I think there is some confusion here, introduced by the article. Your statement is correct, as long as the discussion is confined to the narrow area of energy production - and renewables may indeed require more jobs per the same unit of energy output.

              However, energy production isn't a stand-alone, independent economic component. It relies on a whole swath of other areas - coal mining, oil or natural gas extraction, pipeline construction and maintenance, other fuel transportation industries (like oil or LNG

Also, France has nuclear power to a large extent because France *is* a nuclear power (that is, it built up an industry to produce weapons).

          Last year, 42% of new electricity generation capacity in the U.S. came from land-based wind energy -- more than from any other source -- according to numbers in a series of reports from the Department of Energy (DOE) this week. By contrast, solar amounted to only 38% of new capacity last year.

          That is the vast majority of new capacity. Where subsidies and incentives come into play is accelerating the decommissioning of break even or profitable polluting generators before their end of life as well as financing new capacity where an energy producer might not have enough capital to replace all of their older generators.

The mining required would be environmentally catastrophic. They just ignore that one. Now this guy, with no experience in engineering or the energy industry is declaring you can just make 100% renewables work by just routing the power around. Seriously? Do you think engineers didn't already think of that one? You can make loads of money transferring power around. When it is efficient enough to make it work, we already do that. When it isn't, we don't. Capitalism has all sorts of problems, but using energy efficiently isn't one of them. Capitalism is ruthlessly efficient at using the least energy to do the most. Most heavy industries highest costs are from energy. They often will locate their sites near cheap power. We don't even bother to find bauxite sites anymore because we only locate them near cheap power already. Trying to find some sort of way to do these things even more efficiently is very difficult and some academic with no engineering or industry background certainly won't be able to do it.

      Man, the nuclear fan boys pop up in any energy related post nowadays.

      It would take a half century to deploy a meaningful number of reactors in this country (I mean, do you think we'd even find a meaningful number of communities to accept a nuke plant? I don't.) Not only do we need solutions sooner than this but in that time batteries will likely be all we need given their current rate of development and the massive sums of money being poured into developing better ones.

    And not enough on the negative impacts that don't kill you. Like how there's millions of people with long-term symptoms and effects left over from covid. Air pollution has a wide variety of nasty effects. Decreased intelligence is one of them, and an overall decrease in lung capacity. Never mind the cost of treating people who don't just drop dead.
    • They use deaths because they're an easier indicator to use; life/death is binary. It gets complicated & you have to draw sometimes arbitrary lines when dealing with other adverse health effects, i.e. How sick or injured do they have to be to be counted? But yes, deaths are just one of many detrimental effects from extracting, refining, transporting, & burning fossil fuels around where we live, work, & play.

      The article also talks about variable pricing to achieve flexible demand. It is a pity the study is paywalled. It would be interesting to know what level of demand flexibility they require.
      • I have often thought this would be a good idea. Essentially there could be some mechanism whereby the utility company advertises the price and smart appliances decide if they should use power or not. Refrigerators and air conditioners could let temperatures rise a bit to ride out temporary high prices, for example. Pool pumps and electric dryers could pause. Etc.

          There is some low hanging fruit like you mentioned. But there are also things which will irritate people. It is likely price will be often high when people switch on lights and TVs in the evenings. Worse, if it lasts longer and we need to decide whether to switch on fridges again or let the food spoil. Worst if it leads to stopping e.g. an electric furnace for metal alloy production (that adds hundreds thousand in costs to fix and restart it). That is the reason why the required level of demand flexibility

          I don't doubt you are right, but the above should help. In the UK you'd think there would be similar resistance, but it's pretty much vanished now. I'd like to say I can see on shore wind turbines from my garden and that it doesn't bother me. It doesn't bother me, but the next door house gets in the way of actually seeing them.

      You can get at some of the assumptions made on the Stanford website, they published a summary of the figures there if not the whole paper. I read it when this first came out a few weeks ago, although I haven't gotten the paper (maybe it's on scihub now, it wasn't at the time).

    I'm assured that making individual house chargers into grid-sources is Hard, so for up to four residences, a building can "merely" have car chargers that can be told by the utility to power that building, and subtract its needs from the grid. (As with all below, you would have the ability to p

  • ===Per capita household energy costs were nearly 63% less.=== I do not see the money I spend on energy dropping at all, let alone being 63% less. That raises a concern for me about the entire study, and what it's purpose was.
  • Then, the losers of this scenario know precisely what they stand to lose and they react with political contributions, lobbying, misinformation campaigns, forming trade groups to nip the competition in the bud, buying up patents and create obstacles, doing every thing they can do, legal, illegal, ethical or unethical, moral, immoral or amoral, to prevent the scenario from being realized.

    And those who stand to win by the scenario often are not paying attention, when they do they don't believe it, or they fall victim to misinformation campaigns. Thus a disruptor comes up only when it flies under the radar

    Case in point: Metal Hydride batteries. They looked promising in 1980s. Too promising, Oil companies bought the patents, specifically prohibited their use in automobiles, till they expired in 2019 they were owned by Exxon-Mobil. If all that R&D that went into Lithium Ion had gone into metal hydrides may be some breakthrough could have happened and it could be cheaper or less dependent on rare-earths... Remember Lithium ion did not look promising back then and was dismissed as a viable battery by the Oil companies.

    Then, how did it come to pass? There was demand for stored electric energy. Consumers were willing to pay up to 10,000 $/kWh. Yes, that is not a mistake or exaggeration. The cost of a Lithium Ion battery powering the huge video cameras lugged by the broadcasters, batteries of isolated weather monitoring stations ran into thousands of dollars in price, and their capacity was so pathetic it was measured in milli-ampere-hours. Not even in whole ampere-hours! Then came all those laptops, consumer video cameras, these guys were willing to pay 1000 $/kWh. The demand was so much Toshiba actually created a hydrocarbon fuel cell to power laptops! The butane fuel of the cigarette lighter powered fuel cell to power the laptops! Even before 9/11 FAA would not have allowed those gizmos on an airplane. A quart of butane fuel in every laptop on board? Come on you gotta be kidding!

    This market place was the one that was funding R&D on Lithium Ion batteries. Not pie in sky labs, not university professors begging for research grants from foundations and think-tanks. Bread and butter, dollar and cents, profits and costs of line managers of battery cells and manufacturers. Sony info-lithium batteries kind of things.

    Dot com boom created thousands of millionaires. It is inevitable one of them will have the crazy idea to duct tape 8000 lap top batteries and power a car. It is inevitable because, there was already a Datsun 210 powered by lead-acid batteries that will wipe the floor with the asses of Maseratis and Lamborghinis ... For two runs and then it will be back on the trailer to be recharged. So some dot com millionaire or the other would get into drag strips and someone will plant the idea of replacing the lead acid with laptop batteries. That millionaire turned out to be Elon Musk, who saw lot more than a drag strip toy in that idea. But that is how disruptors emerge.
