    MSE Insert:

    We've seen some debate on this thread about the relevance of some posts to the topic.

    To ensure the thread remains on topic for forumites wanting to discuss the latest news we're asking that all posts contain a link to the news you're discussing.

    For the purposes of this thread the "news" needs to be within the last two weeks.

    Back to Martyn1981's original post.

    ---

    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.

    Tough one this, Swansea Council want to proceed with the tidal lagoon, great. But they now need private investors outside of any government subsidy scheme, not so great.

    My understanding here is that the Swansea lagoon would produce leccy at a pretty high cost, up there with HPC, but, if it proves the consept, then much larger schemes such as the Cardiff lagoon (10x the generation) would generate at about half the cost.

    So Swansea is really important, but really just to get the industry going, a bit like the early high PV rates, to prove the technology but to encourage a larger rollout at a lower cost.

    I wonder if crowdfunding has ever gotten close to £1.3bn?

    They would already have the power cabling fitted for the tidal generation, plus the pv panels are more efficient when they are cooler, which they would be if they're surrounded by water.

    I don't really follow what the BBC fact-checkers are trying to say there ... for example, offshore wind development costs have fallen dramatically since the 2016 report they reference and the later 'more recent study' report from this year is of little relevance as it doesn't support the BEIS report at all - add to this the removal of the EU's MIP on PV panels and the associated effect on large-scale solar & everything changes ...

    Really just shows how ineffective the BBC fact-checkers can be if they have no understanding of the subject they're looking into .... Caroline Lucas also has a different battle to fight, not with the Government or the BBC, but with the NIMBY 'Greens' that habitually oppose on-shore wind developments on a 'loss of amenity' basis ... I'd suggest she would be more effective at delivering by concentrating the majority of her effort into changing lobby & protest group opinion through convincing them to consider the whole 2000 piece jigsaw picture, not just the tiny fragment they hold ...

    Yes, it's worth pointing out that Swansea and Cardiff built barrages almost entirely for aesthetic purposes. The Cardiff one is great to visit with a strong tourism angle.

    No idea if a tidal lagoon could be used for water sports. They would go from empty to full or full to empty in 3.5hrs, with a 2hr slacktide in the middle, so 9hrs of water from little to large and back to little. Perhaps too dangerous .... I've honestly no idea.

    Discussions about the Cardiff lagoon suggested that the barrage wouldn't be open to the public, other than say during a marathon or sporting event. The wall would almost be a half marathon in length, so I suppose you could have issues getting ill people off, or evacuating if a big storm blew in all of a sudden ...... again, making this up as I go along.

    Also a shame that it starts in 2012, as gas generation appears to have risen to displace coal, whereas it was at those levels in the late naughties and dipped down a bit when coal went up, but the sum of coal and gas has dropped roughly by the same amount as RE has grown.

    The graph they publish doesn't even bear any relation to the figures they quote in the article: "The total electricity generation in the UK stood at 336 terawatt-hours (TWh) in 2017, with 29.3% generated by renewable sources of energy."

    29.3% of 336 TWh is 98.4 TWh, but the graph below shows about 35 TWh.

    Ofgem has quarterly stats up to Q1 2018.

    Totaling up the last 4 available quarters gives 64.9 TWh (19.4 %) from wind + solar, 3.4 TWh (1.6%) from hydro and 25.9 TWh (7.7%) from biofuels. If we total them up we get 96.22 TWh (28.8%)

    That compares with nuclear at 63 TWh (18.9 %)

    I'm posting this article simply because I read the title and thought meh! and went to move on. Then it hit me that 355GW's of RE (over 5yrs) is no longer a blow my mind headline - I think that in itself is good news?

    Heard the one about RE generation being unreliable?

    Belgium faces winter blackouts amid nuclear reactor shutdowns

    A forced shutdown of one nuclear reactor in the lead up to winter may be regarded as unfortunate. But the closure of six of the seven reactors responsible for supplying 40% of Belgium’s electricity is raising eyebrows, even in a country so prone to chaotic administration.

    I know that all forms of generation have their pluses and minuses, but faults with nuclear reactors can mean the loss of GW's of generation all at the same time. Is it naughty to point out that the EPR design for HPC is the one being built by EDF in Flamanville that has a faulty reactor lid which will need replacing? And it hasn't even started generating yet!

    Excellent news with RE in some parts of the world closing in on existing coal generation costs (where the cost of the plant may now be fully amortized) so only reflects running costs, fuel etc.. This is important as it not only means RE replacing new FF generation, so a future win, but could mean RE displacing generation from existing FF powerplants, and thereby reducing existing carbon emissions from existing demand.

    Whilst not good news for Aussie coal mining, and the export industry, this article is very promising illustrating the speed at which RE is competing against coal generation, or to be clearer, competing against plans for new coal generation.

    Coal report says Australian exports have peaked and are in 'terminal long-term decline'

    The report said export volumes from the port of Newcastle, the world’s largest coal export harbour, peaked in 2016 and have begun a permanent decline. The conclusion is based on long-term trade forecasts for thermal coal and an analysis of Asian energy markets, where investment in coal-fired power is slowing.
    “Imported thermal coal is now entirely uncompetitive, and possible new markets such as India and Vietnam are pursuing cheaper, more sustainable renewable energy options,” said Buckley, the institute’s director of energy finance studies.

    Buckley said renewables were now about half the cost of imported coal in India.

    A short but interesting theoretical look at 2050 leccy prices, plus demand and supply.

    [The assumption is that demand will rise 2/3rds with a shift to EV's and heat pumps, which is very similar to other such estimates I have seen that average demand will rise from 40GW to 72GW.]

    Summers could be entirely powered by clean energy by 2050


    One thought that occurred to me, based on this assumption:

    But because of higher demand and lower solar output in winter, gas power plants would still be needed to fill in the gaps between November and February.

    Their owners would need an additional payment during winter for being ready to provide backup power when needed, to make the economics work.
    is that if payments are being made to gas to stand by anyway, then instead, we may see those payments going as curtailment to RE, since overcapacity of ever cheaper RE, and the reduction in CO2 emissions from further reducing gas generation, may be a cheaper option.

    Doubt we'll be able to predict the actual choice till we know what price and level of deployment short term battery storage ends up at, and also what amount of longer term storage we settle on, such as hydrogen, or LAES etc etc.

    From coal to pellets, made from waste material.

    Atlantis to convert Uskmouth coal-fired power station in Wales

    SIMEC Atlantis Energy has revealed plans to convert its Uskmouth Power Station in Wales, UK, from coal-fired to energy pellets.

    Using energy pellets that are produced from non-recyclable waste destined for landfill, the power station is expected to generate and export 220MW of baseload power to the grid.

    The energy pellets will be produced using technology developed by a joint venture (JV) between N+P Group (N+P) and SIMEC Energy called SIMEC Subcoal Fuels (SSF). Development will take place on land adjacent to the Uskmouth Power Station.

    This news is so startling that I'm sure it can't be right ..... can it?

    Indiana Utility Says Replacing Coal With Renewables Will Save Customers $4 Billion

    In fact, the analysis that went into creating the IRP shows the plan will save NIPSCO customers more than $4 billion over the next 30 years. The plan will see the role of coal decrease from 65% today to 15% in 2023 before reaching zero in 2028. The company owns and operates the 1900 MW Schahfer coal generating station located in Wheatfield, Indiana. Schahfer is one of the dirtiest facilities in the US, spewing out more than 8 million tons of carbon dioxide a year. Its newest units were built in the 1980s.
    Coal - 65% to zero in 10 years - this is not Trump's week!
