Japan's Richest Man Outlines Renewable Energy Plan 224

itwbennett writes "Speaking at the launch of his Japan Renewable Energy Foundation, Masayoshi Son, founder and CEO of Softbank, outlined a plan to rebuild Japan's energy infrastructure. Son said the country could shift to renewable energy sources for 60 percent of its electricity requirements over the next two decades. He called for a 2 trillion yen (US$26 billion) 'super grid' across the country, and underwater off the coast, that would zip electricity around cheaply and efficiently to meet demand."

    With so few traditional energy resources, Japan will a very difficult time reaching that goal. A few judiciously placed Gen-IV nuclear reactors would be a good idea unless they think they can reach their goal solely through wave energy and geothermal. Not sure what their solar and wind potential might be but they need a solid baseload option to replace nuclear.

      Well, at the very least he's on the right track about the grid itself. If it weren't for the 50-60 split, they wouldn't have had to worry about power outages.

      Currently Gen IV plants are in the research stage. Since they take 20+ years to build, I don't think Japan can afford to risk building a theoretical device to meet today's demand. Since Japan is an island, offshore wind power is probably ideal.

      Let me get this straight. The most successful Japanese business man is going balls to the wall for renewable energy after his country has just experienced what still could become the worst nuclear accident ever. You:

      - Probably have significantly less money that can be invested in ANY project (not that you would bother investing in Japan if you did).
      - Probably do not even HAVE any assets in Japan at risk.
      - Did not even take the time to look up what Japans real alternative energy profile looks like.


      You know, I am assuming you are a fellow American because that seems to be what Americans do all the time, tell the rest of the world what is best for them without even bothering to learn anything about their situation (Hell, it is how Japan first got into the nuke business, to begin with). However, do you think the nuke industry really needs posts like yours? It is really sad to see little people like yourself cheer on the giants who wouldn't lose any sleep if they smeared your little life all over the pavement. Even more pathetic from the eyes of those who have been direct victims of such industry giants.

        Ever heard of Chernobyl, which nearly made the whole of Europe inhabitable, required 600,000 "liquidators" to be mobilised to build a cover on top of the reactor (most of which died of severe radiation poisoning less than 20 years later), bankrupted the USSR (it cost hundred of billions of modern dollars), and removed 10 million of acres of land from Belarus and Ukraine?

        The Fukushima disaster is not close to being the worst nuclear accident at all.

            Not so much...It's a bit in between both of your extremes...

            However deaths appear to be limited to about 1,000 or less (quite possibly under 100) except children getting thyroid cancer.

            Large areas of the land are livable again with basically double normal background radiation (comparable to living in a city with a lot of stone buildings like New York).

            Substantial areas are still (and will be for about 600 years) uninhabitable.

        I've always been a staunch support of renewables but they have to be appropriate to the demand and the location. As one of the world's largest consumers of energy as well as a very developed society, they really can't afford to react out of fear. While this was a great disaster, how many of the 50-odd nuke plants were affected? The biggest problem is that divided grid with only 3 frequency converter stations in the whole country.

    • by gstrickler ( 920733 ) on Monday September 12, 2011 @05:39PM (#37381176)

      Japan is one of the few places that could possibly be powered completely by geothermal. There isn't nearly enough wave energy to supply the planet, nor is there sufficient wave energy near Japan to supply Japan. With a combination of geothermal, wind, hydro, and possibly some solar or wave, Japan might be able to go completely renewable. Most industrialized countries don't have access the the abundant geothermal resources Japan has (due to their location on the edge of the "ring of fire").

      Of renewable sources, solar and wind are the ones that can supply enough power for the world, but both are intermittent sources that are not well suited to supplying either base-load or peak-load power without a significant amount of on-demand energy storage added to the grid. On demand energy storage can be in the form of batteries, super capacitors, gravity reservoirs (e.g. pump water uphill to a reservoir during periods of excess generation, release it through turbines when needed), etc. However, solar requires huge amounts of land. Solar and wind each need more than 4x average demand installed (even with on-demand storage, more still without on-demand storage) because they only average ~25% of installed capacity. Neither solar or wind is viable in all areas, and with it's intermittent nature, the grid must have significantly more capacity to route from locations with excess to locations with a shortage.

      Bottom line, for most of the world, nuclear and/or fossil fuels are the only currently viable means to meet the difference between renewable capacity and peak demand. Fossil fuels will be exhausted in 50-250 years (~50 yrs oil, slightly longer for natural gas, 200+ years coal). Since plants have a 40-80yr life span, fossil fuel plant built today, could run out of fuel before the plant is used up. Nuclear is the only long term solution that is viable today, and even that needs to move to a thorium fuel model with breeder reactors and fuel reprocessing in order to last more than a few hundred years.

        solar requires huge amounts of land

        Even beyond all of the roofs that are readily available for such use?

        • by gstrickler ( 920733 ) on Monday September 12, 2011 @07:45PM (#37382064)

          Yes. Peak solar radiation on the ground is ~ 1kW/m2 in the summer (may be higher in the tropics), and you get that on a cloudless day for a few hours in the middle of the day. It drops off pretty quickly as the sun drops out of the peak. Clouds also lower it dramatically, and you get less in spring, fall, and winter. And less at higher latitudes. And of course, there is none at night.

          Assuming a 2000 sq ft, 3 level home (upstairs, downstairs, and basement), that's about 667 sq ft (~62 m2) of flat roof area. That's a peak of 62kW radiation reaching the roof for a few hours a day in the summer. The best commercial PV solar panels are ~20% efficient, so that's ~12.4kW peak, and if the weather is good an average of maybe 50% of that over 12-15hrs of sunlight, you might produce 70kWh-100kWh on a good summer day You'll be lucky to get half that in the winter. Of course that will be lower as you go to higher latitudes. So, in the summer, with some type of energy storage to give you power when you use it most (early morning, dinner time, evening), a house with it's entire roof covered with PV panels might produce enough power to sustain itself. But that's only 3 months of the year. The rest of the year, you're operating at an energy deficit. If you live where it's frequently cloudy, or north of about 40 degrees latitude, you're not even going to break even in the summer unless you have a very energy efficient home.

          It's not that it's impossible, but most current houses aren't built to be energy efficient enough, nor do they have energy efficient water heaters, heating systems, air conditioning systems, appliances, lighting, or electronics. People have built houses that are powered entirely from solar (usually a combination of PV and thermal) and/or wind. It's just very expensive to do it, and it still requires lifestyle changes.

          And that's not counting industrial energy uses, workplace usage, street lights, traffic signals, or charging electric vehicles (which will be necessary to get off fossil fuels)

          Japanese energy consumption is lower per household, but a home with 62m2 of rooftop space there is very rare, they probably don't average 1/2 that.

          Solar is the ultimate renewable energy source, as long the sun stays in it's main hydrogen burning phase and the earth remains ~ 93M mi (150M km) from the sun, so it's probably good for another 5B years. But until we figure out how to efficiently convert solar to usable power and integrate the collectors into most of our buildings, and build a grid with lots of energy storage and that can transport energy around the world (it's always day/night somewhere), and do it for a lot less than current cost, solar isn't the solution. Long term, it's the best option, but we're at least 100 years off from that just in building the infrastructure to make it possible, and we need several technology breakthroughs to build and utilize that infrastructure. And the politics of power sharing across nations is a big obstacle to any worldwide power grid.

      • Your post is very informative. I think I see an obvious solution from what you've posted.

        Most industrialized countries don't have access the the abundant geothermal resources Japan has (due to their location on the edge of the "ring of fire").

        Let's use the ground as a battery and then geothermal to recapture it!

        What I can't figure out is why nobody in Japan is talking about geothermal. There has been a lot of talk about increasing wind power (and it is noticeably expanding at a good rate already), and building big solar farms (some at sea, which seems like a completely daft idea). But I haven't heard a single word on expanding geothermal, which should be the key for this kind of undertaking. What I'd like to know is why not. The existing geothermal plants seem to be working acceptably, so it should be feasible. I'm a bit suspicious that these renewable initiatives are not as serious as the appear.

          In Japan a 20 MW geothermal plant would cost $50 million. Let's say 4,000 MWs is a typical nuclear plant and that its cost is $6 billion. Japan would have to build 200 geothermal plants at a cost of $10 billion just to replace a single Fukushima Dai-ichi plant. That's $4 billion more than necessary. And it'd be even worse figuring in the cost of infrastructure to connect 200 power plants to the grid. Perhaps that's why nobody is talking about geothermal in Japan.

      • Ignoring how there are lots of energy storage solutions that are improving from batteries to hydrogen stored in metal hydrides, what about simple thermal storage in molten salt?
        http://www.physorg.com/news/2011-07-gemasolar-solar-thermal-power-hours.html [physorg.com]
        "The Gemasolar 19.9-MW Concentrated Solar Power system is a âoepower towerâ plant, consisting of an array of 2,650 heliostats (mirrors) that aim solar radiation at the top of a 140-m (450-ft) central tower. The radiation heats molten salts that circulate inside the tower to temperatures of more than 500 ÂC (932 ÂF). The hot molten salts are then stored in tanks that are specially designed to maintain the high temperatures. This cutting-edge heat storage system enables the power plant to run steam turbines and generate electricity for up to 15 hours without any incoming solar radiation."

        Why not just have solar PV heat molten salt, too? So, there are solutions.

        Thorium power would be cool, true. But we'll probably have hot or cold fusion soon enough, rendering it obsolete.

        • by gstrickler ( 920733 ) on Monday September 12, 2011 @10:56PM (#37382942)

          Converting electricity to heat and vice-versa is not very efficient. Converting solar PV to heat is a terrible idea for that reason. You'll lose energy converting electricity to heat, then even more converting back. Much better to just use solar thermal in the first place. Carnot's theorem [wikipedia.org] says the efficiency of heat to work conversion is limited by the ratio of absolute temperatures of the heat source and heat sink (e.g. ambient temperature). With a cooling source at 300K (27C), you need at least 600K heat source to achieve 50% efficiency.

          Thorium reactors are known to work. We've never demonstrated a self sustaining fusion reaction outside of the massive gravity well of a star. If/when we do, then maybe fusion will make thorium reactors obsolete, but right now, fusion is still a pipe dream.

        "Say what you want, but Softbank really brought the iphone revolution"

        No, not really. They were a newly started/aqcuired network (softbank bought a failing network wholesale) with few customers and a reputation for lousy infrastructure. They were the only network willing to accede to Apple's conditions for selling the iPhone (rumour has it Apple was holding out for NTT Docomo to the end but the negotiations fell through). Apple got a compliant network and Softbank got a cash cow to drive subscribers.

        But Softbank only "brought the iPhone revolution" because they were the only network willing to bend to Apples conditions.

            If you lived in Tokyo, then virtually any company will have reasonably good coverage. But Japan is a lot bigger than Tokyo. When I first came to Japan I was with Softbank mainly because they supposedly have an English help line (although every time I called it, it was out of service). Living in a small town in Shizuoka prefecture, I could not conduct telephone calls in my apartment because the signal was poor. I had to go out doors. Wherever I went, I had about a 50% chance of receiving telephone calls. Well, I don't phone a lot, so I put up with it, and 3G coverage was OK, so I could get email. But over time, the 3G coverage got worse. It got to a point where I couldn't connect to the network most of the time, and I couldn't get emails. Softbank was cheap, but last year I changed to Docomo since "cheap and not working" is not as good as "expensive and working".

            Similarly, I have been using Yahoo! Softbank ADSL (Hikari is only being rolled out in my town this month). I had good internet connection initially for about 6 months, and then it slowed down to dialup speeds. I phoned them up (in Japanese since their English help line didn't pick up) and got a new modem. That one lasted another 6 months. Rinse and repeat. After going through 6 modems, they decided that there must be something wrong with my line (you think...). So they scheduled NTT to come and look at the line. No change. So they remotely tuned the receiver on my modem and that fixed it for 3 weeks. At that point they didn't know what else to do, so I was left with dialup speed (or less) for a good year. I'm 50 meters from the end office, and while it's hard to fault Softbank for a crappy phone line (they don't own the phone lines), given the fact that new modems fix the problem for a while, I have to think that the modem is not as robust as it could be. As I said, Hikari is being rolled out this month and I'm already scheduled to be switched over to NTT.

            As far as the iPhone goes, it is true that Softbank was the first to roll out a smart phone. All the other carriers refused to carry the iPhone as the other poster noted. But it wasn't long before Docomo came out with the Xperia (Android). In fact you will notice now that Android phones absolutely bury the iPhone in numbers and popularity. The iPhone is still popular with foreigners, but I barely see any Japanese people carrying one.

            I also think you are wrong to say that Softbank brought the "iPhone revolution". Whether or not the other carriers realised the importance of smart phones at that time, or whether they were waiting for Android phones I don't know. Au was especially slow, but has certainly jumped in with both feet as you can know choose from something like 6 different Android models. Even Softbank carries Android phones now. When the revolution came, it was Android, not Apple.

            Like I said. I don't doubt that your experience with Softbank was good. Friends of mine in big cities use Softbank and are happy. But with respect to the OP's point that Softbank has a horrible network compared to Docomo and Au, he's right on. Softbank is virtually unusable in a lot of places in Japan, which is why it isn't popular. And while we can give credit where it's due for taking a chance on smart phones, the bigger companies did a much better job following through and dominate the market in that area too.

            I'm not as hard on Softbank as the OP. I'm happy there is some competition. I just wish it were stronger.

      Hey, now while I'm no fan of either stimulus plan I object to the "wealth redistribution" class warfare rhetoric. We can't discuss class unless it is to defend the wealthy!

      To be more serious, the wealthy have been waging a PR driven class war against everybody else for decades; both of Obama's plans give in heavily to the ruling class and still had/have a big uphill battle for the tiny portion that is ok. This current one will not pass for multiple reasons; one of the big ones being that tax loopholes the wealthy use to CHEAT are being closed to help fund tax cuts for the rest who've been picking up the bill for the wealthy --- the wealth HAS been redistributed upwards at increasing amounts for decades; their pay goes up while the rest are lucky to keep up with inflation (and most do not; including myself... I've never had a job that kept up with inflation.)

      Tax derivatives less than 1% and you pretty much fix our budget issues. "Business" which does not benefit the real economy should be taxed like the gambling it is. Instead, we continue to let them expand their addiction to our retirement funds and soon our social security funds.

      Sigh... we could have replaced all of our coal power plants for that price, or expanded all of our overloaded interstates by a lane, or, hell, built a smart grid of our own.

      Honestly what is wrong with a little wealth redistribution?
      I realize it is not popular on slashdot, but if that is what our economy needs so be it. When the rich have all the money they don't spend it. If we give that to the poor, they will spend it right away.

    That is the important item. In addition, add storage. Once you have that, you can move in and out with energy generation.

    ....hardware isn't your area of expertise, Mr. Son. Japan needs nuclear power, it is even less suited to wind & solar than other places, and has practically no fossil fuels. However, nuclear energy can be cleaner, safer, and more efficient than it is, by the use of molten salts for cooling and fuel delivery. The best example of this are Liquid Fluoride Thorium Reactors...see http://www.EnergyFromThorium.com

      When will you guys finally understand, that doing everything just one way is the surest way to fail. There is no reason not to use wind, solar, geothermal or biomass where it is available and where it can be used sustainably with minimal (additional) damage to the environment. Of course, it's not necessarily cheap and I don't believe there is enough of them to provide for all the energy we need.

      But again, no reason not to use them, provided that the public isn't being mislead about costs and usefulness of the results. Otherwise, it's going to end just like NASA.

    A few obvious questions about those renewable energy sources he wants to use:

    Which ones? Are they used in a sustainable way? Where will it be placed? Who will finance it how? What are the limits to environmental damage and destruction caused by them? How will energy from wind and solar be stored? Who will pay for use and installation of storage? What will be the energy source for the other 40% of electricity? What will they do about the other 60% or so of energy that are not electricity and are currently provided mostly by gas and oil, being used for heating, industrial processes and powering vehicles?

    Just wondering if his plan fixes and replaces the 2 different power grids Japan has. They have a 50Hz grid and a 60Hz grid, with several power converts between the grids, but they can only handle about 1GW of power transferred between the two grids (which is why when the earthquake/tsunami caused many of the nuclear plants to shutdown, even though they had the capacity on the other grid to handle the losses, they didn't have the ability to transfer the power to the other grid, and had to have rolling blackouts in Tokyo since it was located in the same grid affected by the shutdowns).

    a massive grid that would run 36,000 kilometers and link Japan with countries including India, China, and Russia.

    It's only a matter of time until we have Buckminster Fuller's Dymaxion power grid. [youtube.com]

I am more bored than you could ever possibly be. Go back to work.

Working...
