    Green, ethical, energy issues in the news. 9th Jun 15 at 7:25 AM
    I thought it might be a good idea to have a thread for posting general news items that may be of interest.

    PV and the 'Solar in the news' thread attract a lot of interest, so here's a thread for all the other goings on.

    Another One Bites The Dust: Cost Of Wind Power Cancels Kansas Coal Facility Expansion

    Even the Koch brothers with all their money can’t fight the benefits that renewable energy adds to a utility company’s bottom line.

    Hi All

    Interesting comments from Rolls Royce following the offshore wind price mic drop ...

    Some light reading on nukes if you can stay awake, but here's the bit on SMR's:-

    The World Nuclear Industry Status Report 2017

    Conclusion on Small Modular Reactors

    Since 2015, when WNISR included a section on small modular reactors, there have been two kinds of developments. First, as we have documented above, a few SMR designs have progressed towards construction as well as completion; one SMR project (in China) is reportedly to start up in 2018. But the implication of this progress is questionable because of the second development, namely the decline in even the stated interest, let alone the actual market for SMRs that can be backed up with financial commitment. A good example of the decline in interest can be seen in the case of the HTR-PM being built in China. When construction of that reactor started, there was talk about building 18 more such reactors. That has vanished, presumably because of the realization of the high costs of electricity from these power plants. Unfavorable economics is also the reason for there being no market for the SMART reactor in South Korea.

    The decline in interest in SMRs is, of course, related to the decline in the interest in large nuclear reactors as well. The problems associated with mPower and the Westinghouse SMR are, in the final analysis, related to the absence of a market for SMRs in the United States. Likewise, many developing countries claim to be interested in SMRs but few seem to be willing to invest in the construction of one.

    This latter factor has made it more difficult, perhaps impossible, for any SMR design to become a commercial success. This is clearly illustrated by the saga of mPower. Despite the expenditure of hundreds of millions of dollars, some of the biggest companies in the nuclear business could not succeed in commercializing a reactor design that had been described by The New York Times as being in the lead in the race to develop SMRs, in part because it had “the Energy Department and the T.V.A. in its camp”.

    Of course, with powerful entities like the U.S. Department of Energy continuing to financially support the construction of SMRs, it is possible that one or two SMR projects might even start getting built over the next decade or beyond. But it appears that such projects would have to be supported by government funding in a major way if they are to be completed. There is no sign at this point that SMRs could play any major role in tomorrow’s electricity generating business.

    Renewable Energy Sources To Account For 85% Of Global Electricity Production By 2050

    “Until 2050 the electricity share of energy demand will grow from 18% to 40% yet this transformation is not happening fast enough. Speeding up the acceleration of electrifying sectors like heat and transport will be one vital measure to put the brakes on global warming. The climate challenge is not an engineering challenge, but one of governance. We call upon all stakeholders to maximise the electrification of their operations.”
    So leccy is just a small(ish) part of the problem, but 85% of 40% is a massive increase by 2050.

    RE plus storage getting cheaper, and options greater than just Li-ion.

    VIZn claims to deliver energy storage for renewables at record low price

    Installing a 30MW, 4-hour duration VIZn zinc-iron battery storage system to a new 100MW solar PV plant could, through a US$0.04 power purchase agreement (PPA), result in a 7% internal rate of return (IRR), VIZn claimed. Energy-Storage.News was told by the company’s spokesman that this IRR included total turnkey costs and ongoing operational costs.

    For a quick(ish) lesson on RE today and the future, this article is absolutely great. Worth a read, and a click-on and ponder of each graphic, which are very educational.

    Also worth noting the IEA projections. They expect solar to become the leading source of leccy in the future, despite all of their projections being linear, and massively wrong. Even in 2016 they were projecting annual deployments of PV of approx 50GWp pa through to 2040, but 2017 will be around 100GWp.

    Very interesting. And does make one wonder what on earth the government was thinking when it pulled the plug on much of it's RE support and threw it's weight behind Hinckley Point.
