US Funds Aggressive Tech To Cut Solar Power Costs 272

coondoggie writes "The U.S Department of Energy wants researchers and scientists to 'think outside the box' and come up 'highly disruptive Concentrating Solar Power technologies that will meet 6/kWh cost targets by the end of the decade.' The DOE's 'SunShot Concentrating Solar Power R&D' is a multimillion dollar endeavor that intends to look beyond what it calls the incremental near-term to support research into transformative technologies that will break through performance barriers known today, such as efficiency and temperature limitations."

        The natural counter-argument is the question: Should the government stop funding research simply because some of the funds will (likely) reach undeserving parties?
        It's not black and white. If there's been a history of wasted resources related to this particular objective, then more strict regulation should be enacted (and the natural reply to this would be: regulation is both expensive and corruptible... I guess some middle-ground is necessary).

        How do you think nuclear got started? Once we went beyond coal, gas and hydro the cost of developing new sources quickly got too high for the market to fund. We, as a society, need this stuff to ensure our future prosperity and comfort so we have to encourage development.

        You could argue that government is bad at investing in things, but part of that is because it is the only body willing to invest in expensive new technologies where the risk of losing out on your investment is high. Just look at the number

        You could easily swap "solar power" for "defense systems". The scandals related to government support of solar power pale by a few orders of magnitude to the overt graft and fraud in military research and acquisition. What's your point? Are you suggestion that we shouldn't be funding either?

          This. At the peak of their research time lines the Manhattan project and the Apollo projects reach 0.4% of our GDP spent JUST on those individual projects. I would submit that this kind of commitment is what it will take to get solar/wind/whatever to "the next level." Either way the technology is going to improve and we'll eventually get "there." The question is how long we want to wait and what kinds of resources are we willing to commit to it?

        Yes. Of course the "scandal that comes to mind" ignores the what, 99%+ of those funds that were NOT involved in a scandal there were put to work as intended. Heck, let's be generous to your point and say only 90% weren't scandal-laden. Also, solar power is now beating grid parity in parts of the US, largely thanks to solar incentives and investment over the last several years getting the market going. Not just in the US, but here, in europe, and in china as well. This is a huge moment, where those with enough capital in parts of the us (including the northeast) could choose to "prebuy" their electricity for the next 25 years with PV... WITHOUT incentive... and not lose money compared to grid electricity. In a few more years it's going to be a slam dunk.

        Public policy works. Funding research works. Give up the tired, weak whining that it's not perfect. Waiting for teh "free market" to fix it all isn't perfect either, and it cares a lot less for the collateral damage of a sudden catastrophic shift than we do.

        That's still a mostly bogus number. Besides the hard facts (cents per kW under STC, usually called kWp or kW peak) that number also includes projections about the longevity of the cells and the environmental conditions of their use, which are wide open to manipulation.

        The interesting numbers for solar cells are kWp/m^2 so that you can calculate the area you need and the price per square meter so that you can calculate the upfront cost.

        • The value of kWp/m^2 is a factor in the overall result. If someone managed to find an extremely cheap solution that takes up more space than usual, that's still useful in certain situations. Of course the opposite is also true -- if you find an expensive way to convert solar energy more efficiently (using a smaller footprint), there's a use for that too. Advancement in both cases is beneficial.
        • For materials research, I expect that $/kWh is the more important figure. Obviously you need to know the price per square metre once you start thinking about engineering a device, but this work will be tacking problems of longevity, efficiency and cost first and foremost.

    • That assumes that the only way the US can benefit from advances in the technology is if US companies are producing the technology. In fact, cheaper solar is a massive benefit to all countries, no matter who builds the tech. In my ideal world governments would do far more of this and they would share the results of the R&D far more openly and leave companies to compete by doing what they do best (taking the tech and either marketing it well, enhancing build quality or reducing costs further).

    Achieving 6c/KWHr for baseload ie available any time you want it 24 hours a day, with solar is a fundamentally hard problem. You're up against the 2nd law of thermodynamics. Solar energy is both dilute and intermittent.

    Nuclear is far easier. It is starts out incredibly concentrated. Third generation plants like the AP1000 are extremely safe. If you don't want to reuse the waste it's easy enough to bury it 1 km underground where it won't bother anyone.

    It's far easier to change the minds of people than the laws of Physics.

    Looks like the USA and Europe will leave it to China to develop cheap nukes and become the driver of human civilization in the 21st century.

    • by Hentes ( 2461350 )

      Yes, the biggest problem with energy today is not production but storage and transportation. But nuclear has similar problems as its output can't be changed effectively. Consumption changes rapidly, and the only way to solve this today is a mixed system, where the constant part of electricity is produced by nuclear and coal while the dinamic part is produced by gas and water.

        Modern or new Nuclear can load follow as much and as fast as you like (aka *not* PWR or BWR that suck on every metric). Just because 40 year old designs couldn't does not mean they can't.
      • But nuclear has similar problems as its output can't be changed effectively.

        Not really. Properly designed nuclear plants (e.g. Bruce Nuclear) can do that just fine. You just adjust the power output via the steam loop rather than the reactor, neatly dodging the xenon poisoning problem.

      This is solar thermal, not photovoltaic. The basic idea is to grab a large area where the sun is pretty much always shining during the day (you do have a desert or two, you know), set up a lot of mirrors, and heat the top of a tower. Fill the tower with some form of salt that will become liquid at high temperature, and will hold heat well (solving the night time issue), and they use the heat from the salt to power a conventional steam generator. There are a few installations of this sort, and it works well. They're just looking at how to make it a little cheaper.
    • I recently heard that the reason solar is becoming so popular is that water costs in certain areas are starting to increase significantly. That means the cost of any power generation that requires water for cooling (like nuclear generation) are seeing their costs uncontrollably increase.

      Add to that the fact that more and more people are starting to work from home and small/distributed power generation (like solar plants) starts to become more and more cost effective.

        Umm, no.

        Power generation that uses water for cooling typically sucks the water directly from a river, and spits out the slightly warmer water back into the river.

    But the gov't shouldn't be subsidizing anything, it shouldn't be taxing/borrowing/printing and subsidizing with that money. It should leave people alone and should allow them to work it out in the market.

    How would gov't know that the best course of action is these solar panels or anything for that matter? What gov't should be doing is stepping out of the way, dramatically shrinking its own spending (now 10% of US population is working for gov't, this includes contractors and military, this gov't force should be 100 times smaller).

    But the point is that private sector has to figure out the way, companies must try and fail, most of them will fail, somebody will figure something and if that doesn't happen, then there is no way, and gov't spending is just a waste and another resource mis-allocation.

    They really shouldn't be preventing private companies and people from trying more stuff with nuclear power, that's most likely the only true source of energy that we will be able to use once oil and coal and gas run out. Nuclear and at some point thermonuclear. Solar is great for local applications, but it will not replace the constant need for energy that only things like oil/coal/gas/nuclear/hydro can supply. At some point this will become the revelation that people don't have a choice and they have to rely on nuclear.
