Greens target tots, teeth and solar power
THE Greens have urged disenchanted Labor voters to think twice about supporting the Coalition and instead switch their vote to the Greens, pledging free preschool, more dental funding and solar thermal power plants. The Greens' federal leader, Bob Brown, joined candidates at Balmain Town Hall yesterday for the party's campaign launch in a suburb that was once Labor heartland. Balmain and Marrickville are the two lower house seats the party is tipped to win on March 26. The upper house MP David Shoebridge said there was a clear appetite for change that would not be met by the Coalition, which is widely backed to win the election and could, with the support of the Shooters and Fishers and Christian Democratic parties, control the upper house. Advertisement: Story continues below ''Real change isn't electing a new government that is just going to outsource, to downsize, to franchise and to privatise our key assets and public services,'' Mr Shoebridge said. Three big policy commitments were made at the launch, including three new baseload solar thermal plants in the state's central west. The first plant would cost $2.1 billion, paid for by issuing $525 million of Green Bonds for each of the four years of construction. The party also pledged to provide two years' free preschool education for every child, a program targeting 10,000 children in its first stage at a cost of $128 million, and to boost dental care funding by $102.5 million. Senator Brown said the Coalition leader, Barry O'Farrell, should not be trusted on the environment: ''We've already seen a much more moderate Coalition regime [in Victoria] bring 400 cattle into the delicate alpine national parks of Australia, with no scientific study.'' A recent Newspoll showed primary support for the Greens plummeting 6 points to 11 per cent, while a recent Galaxy poll showed a boost in Greens support in Marrickville to 44 per cent of the primary vote compared with Labor's 33 per cent. The Coalition yesterday dismissed the Greens' attacks and pointed to their federal alliance with Labor on issues such as the carbon tax. The Greens have ruled out preferencing Labor in the upper house and most lower house seats. http://www.smh.com.au/national/state-election-2011/greens-target-tots-teeth-and-solar-power-20110313-1bt28.html |

As I mentioned to you previously Solar Thermal would be the ideal way to go however it costs are massively high and excessive when compared with the cheaper alternatives.
The cheapest energy is coal. The next best alternative to coal is nuclear. It is clean, it safe and it is cheap. |

Masdar Raises $600 Million for U.A.E. Solar Project With Total,
AbengoaMasdar, the Abu Dhabi-backed renewable energy company, and its European partners Total SA (FP) and Abengoa SA (ABG) raised $600 million in financing for the Shams 1 concentrated solar thermal plant. Shams Power Co. received a 22-year loan from 10 lenders including BNP Paribas (BNP), which is also the financial adviser, and National Bank of Abu Dhabi PJSC (NBAD), according to an e-mailed statement today. Abu Dhabi, the capital of the United Arab Emirates and holder of almost all of the country’s oil reserves, is expanding its use of solar and wind power in an effort to become a regional hub for renewable energy. The emirate is building Masdar City, a business and residential complex designed to emit minimal carbon emissions, and serves as headquarters for the International Renewable Energy Agency. Shams 1 will be one of the largest concentrated solar power plants in the world, extending over an area of 2.5 square kilometers with a capacity of 100 megawatts. Concentrated solar reflects sunlight, usually with mirrors, to heat liquids that generate power with steam turbines. Photovoltaic plants use solar panels that convert sulight directly to electricity. Shams Power, which will build, operate and maintain Shams 1, is 60 percent owned by Masdar. Total and Abengoa hold 20 percent each. Construction began in the third quarter of 2010 and will be completed in two years, the statement said. http://www.bloomberg.com/news/2011-03-07/masdar-raises-600-million-for-shams-solar-project-with-total-abengoa.html |

Researchers Use Molten Salt Mixtures to Boost Solar Thermal Plant Efficiency
Siemens aims to enhance the solar thermal plant’s efficiency and in turn reduce power generation costs. Hence, the company’s researchers intend to use molten salts, a blend of potassium and sodium nitrates, in solar thermal projects. To achieve this aim, Siemens plans to build a pilot facility in Portugal for testing application of molten salts as a heat transfer medium in parabolic power plants. The parabolic power plants employ concave parabolic mirrors, which focuses sunlight using an absorber tube. The tube allows the heat transfer medium to flow through it. Later, the heat gets transformed into power by a generator and a steam turbine. Heat transfer medium’s highest working temperature determines the thermal power process efficiency. University of Evora in Portugal has been chosen for construction of the pilot facility. The plant will be equipped with a steam generator, pipework system, solar components and pumps to manage the temperatures and properties of heat transfer media and molten salts. Siemens’ scientists will use the pilot results for implementation at commercial plants with more than 50 MW of installed powers. Federal Ministry for the Environment, Germany is funding this solar thermal pilot plant project. Siemens Corporate Technology and Siemens Energy researchers work on a major goal to enhance properties and composition of molten salts. Molten salts will be used as an alternative for thermal oil. This boosts the working temperatures ranging from 400° to over 500° Celsius. High vapor pressure and extremely flammable property are major drawbacks of thermal oil, whereas molten salts have about zero vapor pressure and they are non-flammable. Hence, power plant operations will be safe without pressure. In addition, molten salt mixtures possess greater heat storage ability and they are economical for use. http://www.azom.com/news.asp?newsID=28387 |

Renewed fears about the technology may also snuff out a nuclear renaissance worldwide that had been sparked by fears over climate change and a need for low-carbon energy.

I was just doing some research, and found that in 2004 we had 50GW of electricity generation.
So I presume in 2020 we will need about 55 - 60 GW of generation. 50% of that generation is currently from coal. That fits with Ziggy's 25 NPPs, each being about 1.5 GW. Each station might have multiple reactors. So how much will 25 nuclear reactors cost to build? |

Debating with myself. This is fun.
http://nuclearfissionary.com/2010/03/23/new-nuclear-construction-vogtle-unit-3-and-4/ So, in Georgia USA, two of these units are being built, total cost US$14B. That's $7B each (if we could build them that cheaply - I am sceptical). And the owners are accessing $3.4B loan guarantee from the US government. $7B x 25 ----- $175B. And extrapolated for 25 units, that involves about $42B worth of loan guarantee from the government. Plus infrastructure costs. |

In my opinion, the only thing that matters is how much we GENERATE now (because we know that works) and what the projections are. 50GW in 2004 (i'm sure the more current figures are out there, but I didn't find them in my quick search), with some growth - I thought a conservative 55-60 GW. |

No, 2 x AP1000s will produce 2200 MW. 25 AP1000's will produce half of Australia's current total electricity requirement. ie 25 x 1.1 GW = 27.5 GW, which is half of the 55 GW we will need (rough figures). 1.

Don't think that the 'pro-nuke' lobby is suggesting 100% nuclear power......because as far as I can see, they're NOT.... The only suggestion is to replace the coal power stations with nuclear power..and since some of the coal power station produce as little as 12mw, you wouldn't even need as many nuclear power stations as there are coal power stations... It's a combination idea (from MY view, anyway)....Solar, wind, hydro, tidal, maybe gas (although that's still a little Co2 intensive) AND some nuclear for backup, at night, or when it's a still day etc... So you'd probably only need a quarter or less of the current number of coal stations...just to take up the load at night, or when the wind drops, or what have you.... |

The ability to ever calculate accurately just what "LONG TERM" costs we will be left to deal with, when talking about Nuclear Power, is the hidden expense that never seems to be considered, when discussing the economic viability of Nuclear, vs Renewable Energy options.
Until that glaring commission is rectified, then we are really making judgment calls, based on false figures. The following article gives a bit of info on just that subject, and is worth a browse, especially if the cost of Nuclear Power is the dominant reason that you would support it over Solar. http://centernanosociety.blogspot.com/2011/03/long-term-energy-generation-costs.html |

Gizmo, take a deep breath and read what I wrote. Half of Australia's current electricity generation is coal fired. The other half comes from other sources. That's about 25 GW from coal. If we replace all the coal fired power stations with Nuclear (that's my assumption), that coincides with Ziggy's estimate of 25 reactors (ie 25 reactors at 1.1 GW each). Does that make sense to you? And a government enquiry would assume that the technology currently being installed in the USA (back in 2007) would be the way to go - what else would you install? The reactors that they are phasing out? |

And THAT is where you made the mistake Ernie......while 'half' of Australia's current power generation IS coal powered, that doesn't mean that we'd need as many nuclear reactors as our current coal power stations... nuclear produces a far higher MWH rating than some (or most) of the coal stations...some of the 'current' coal power stations produce as little as 12MWH....So 2 nuclear stations would more than replace 10 coal stations.......A 151 Mw coal station (of which there are several) produces only 15% of the power that an AP1000 reactor produces, yes???

Title: Re: Solar Thermal Energy For Australia Post by Ernie on Mar 16th, 2011 at 3:46pm
But ziggy recommended 25 (reactors or power stations).
He didn't say one, or five, he said 25. Yes, you could replace several coal fired power stations with one NPP. That's not in question. So I guess you;re now saying that the number of (reactors/power stations) is fluid? How many then? |
Title: Re: Solar Thermal Energy For Australia Post by Ernie on Mar 16th, 2011 at 3:47pm
"that doesn't mean that we'd need as many nuclear reactors as our current coal power stations"
We would need enough to generate the same amount of electricity that the coal stations that are being replaced produce. Logical? |
Title: Re: Solar Thermal Energy For Australia Post by life_goes_on on Mar 16th, 2011 at 3:52pm
A nuclear power station houses more than one reactor.
If you could supply all of the country with just one power station - you'd still need a minimum of two of them. |

Yes. To produce 2.5 GW each in each power STATION, it would need 3 x 1 GW reactors. That's the unit of currency. But we "need" to replace 25 GW of coal fired power. So that's 25 Reactors at 1 GW each. Yes??? |

Title: Re: Solar Thermal Energy For Australia Post by Ernie on Mar 17th, 2011 at 11:59am
He told The Australian Online today the assessment was based on the assumption it would take much longer to start up the first reactor.
“In the review we did in 2006 for example we estimate it would take 15 years to get the first reactor up once you got policy approval. Since then another number of countries including Italy have forecast or have undertaken programs aimed at building a reactor within 10 years,” he said. “I formed the view that we have both the capability in Australia and evidence of an accelerated process overseas that we could move faster than we thought in 2006. “My view is that if we get to 50 reactors by 2050, they would produce about 75 gigawatts of electricity which would be about 90 per cent of the country's needs. http://www.theaustralian.com.au/politics/ziggy-switkowski-calls-for-50-nuclear-reactors-in-australia-by-2050/story-e6frgczf-1225851024425 |
Title: Re: Solar Thermal Energy For Australia Post by Ernie on Mar 17th, 2011 at 12:03pm
Australia has 38 per cent of the world's uranium reserves and 20 per cent of global production. In energy terms, uranium may overtake oil as the key fuel later this century. Australia can lead as a supplier nation, and further opportunities exist.
Australia could and should plan for its first nuclear reactor by 2020 aiming for a fleet size of 50 large reactors by 2050. With a moderate amount of hydroelectricity, renewable and residual coal/gas generation, this could meet all Australia's electricity needs reliably, safely, cleanly and cost effectively. It solves our greenhouse gas challenge in the electricity sector completely, provides for energy security and independence, creates a modern high-technology industry and establishes the energy platform which can charge electric cars and produce hydrogen fuel dependably and cleanly as will be required in the latter part of this century. Compact reactors are expected on the market by about 2015. These reactors are appealing because they are gas cooled (and therefore do not require access to water), can be incrementally extended, are perhaps the size of two shipping containers, can be built underground, and are much less intimidating than a full-scale installation. The introduction of nuclear power via these smaller installations may be the path which wins Australian community and political support earliest. http://www.smh.com.au/opinion/politics/australia-must-add-a-dash-of-nuclear-ambition-to-its-energy-agenda-20091201-k3pq.html |

Basically, what I don't accept about your picture ( 25 reactors) is that it seems to ignore the 'renewable' power generation systems... Granted we 'currently' get 50% of our power from coal....but that doesn't need to continue......There's still solar, solar thermal (which is not quite up to baseload yet), wind, tidal, wave and the gas combined system (which seems good, depending on the natural gas reserves)... So with ALL those other methods, it shouldn't be necessary to replace ALL the coal stations with nuclear stations....some of the coal stations are pretty low capacity after all.. I'm not entirely sure that you'd 'need' 25 reactors (straight away) to meet our power needs... As for the waste problem, reproccesing through 'breeder' reactors can recover up to 95% the uranium from waste material... |
Title: Re: Solar Thermal Energy For Australia Post by Ernie on Mar 17th, 2011 at 2:37pm
Gizmo
60GW of power generation in Australia. 50% of that is from coal, 50% from other sources (rough figures) - hydro, solar, wind etc. So in terms of replaing coal power generation, we're talking about 30GW. Ziggy in 2006 talked about 25 reactors. 25 reactors to produce 30 GW suits the "workhorse" Gen III reactor, the westinghouse AP1000, which the USA are installing, and China. It's my bet that any Australian installation would go with those reactors. In 2009 he talked about 50 reactors, stating that smaller scale reactors would become available in 2016 - the sort that could power a small town, for instance. So, 25 AP1000 reactors to produce 30GW of electricity comes to at least $175B. Where do you think I am wrong? |

Simply on the percent of generation..if we increase our 'other' sources generation to, say 75%, then we'd halve our requirements for AP1000 reactors, wouldn't we?? And if we add 'battery storage' to our solar,wind and tidal/wave generating capacity, the number of reactors 'required' would drop even further.. |

Title: Re: Solar Thermal Energy For Australia Post by Ernie on Mar 18th, 2011 at 3:40pm
So is there any reason for you to continue supporting nuclear?
Gas fired Cogeneration plants are cheaper to build, more flexible, don't need access to major water supplies (future NPPs according to Ziggy will not have this limitation) with none of the drawbacks, and would answer our GG emmisions problems. Because they are cogen plants, other power sources could be piggybacked, if gas fired became less attractive. For mine, I would like to see more companies do what AGL's customer has done - build their own plants, with short payback periods, and take the load off the "public" infrastructure. Towns could take the same approach. There are even cogen machines for houses, which use Stirling Engines - amazing technology, but too expensive. But that will change. |

I have repeatedly tried to get this through to you: I am NOT an advocate for nuclear power but rather I would like it to remain an option for us. the anti-nuke debate has remained predominatly hysterical and devoid of facts. At the moment the economics are not in it but however, with a 10year lead time on construction we need to consider future costs. Nuclear is way cheaper than R/E and obviously has baseload - something R/E generally does not have. Its disadvantages of course are waste and the very high capital cost before any power is generated. So just to repeat... I am not an ADVOCATE for nuclear energy but rather wish it to remain one of the options on the table. Is that clear? |

Poor diddums. You're a rude arrogant hypocrite, whose debating style is pure bluster and misrepresentation. To my recollection, you have made this claim twice, and only after the tsunami in Japan. You have been a constant advocate for nuclear. You have defended it in every argument, and dismissed or disparaged every other form of energy generation as either too expensive or somehow unacceptable. Now that nuclear is a bit more on the nose (temporarily I suspect) you want to appear open minded. Bollocks. |
