Renewable Energy

Chimney stack? Certainly have one. In fact, the fire is on as I write this - the temp tonight will be dropping to around 1 or 2 Celsius where I live, just to the west of Brisbane. We had a decent frost the other morning.


Air-con? Absolutely! Great climate, but during Jan/Feb, it can be high 30s or over 40, and humidity in the 80-100% range. Nasty - aircon almost one of the essentials :)


And reverse cycle air-con is the most energy-efficient form of heating, I gather, for when a fire is impractical (no wood, going out, just come in, whatever).

:biggrin: just having a little tease, sounds like a great place to live.

Mate I have been up round the tropic of C in mid winter and near froze my goolies off.

Anywhere away from the coast gets just as cold as it does down here in nsw.

Short term (say ~5 years), none of these bio-fuels can compete with oil, without massive Gov. subsidies & for as long as it can, OPEC will juggle oil supplies (& hence the oil price) to maintain oils premium demand.

Here is info about another report showing that the fossil fuel sector is getting somewhat of a free ride from governments.


ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’â€Â¦ÃƒƒÂ¢Ãƒ¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…âہ“One of the reasons the clean energy sector is starved of funding is because mainstream investors worry that renewable energy only works with direct government support,ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’â€Å¡Ãƒƒâہ¡ÃƒÆ’‚ said Michael Liebreich, chief executive of New Energy Finance. ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’â€Â¦ÃƒƒÂ¢Ãƒ¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…âہ“This analysis shows that the global direct subsidy for fossil fuels is around ten times the subsidy for renewables.ÃÆâ€â„¢ÃƒÆ’ƒâہ¡ÃƒÆ’‚¢ÃƒÆ’¢Ã¢Ã¢Ã¢Ã¢â€š¬Ã…¡Ãƒâ€šÃ‚¬ÃƒÆ’…¡Ãƒâہ¡ÃƒÆ’‚¬ÃƒÆ’â€Å¡Ãƒƒâہ¡ÃƒÆ’‚ÂÂ




Of course the fossil fuel lobby would counter that fossil fuels are massively more significant in the energy equation than renewables and so it terms of energy delivered they are relatively undersubsidised.

pity they're not an ASX company :sadsmiley02:

They'd fit nicely into my "AE portfolio".

The following was posted by the always energetic poster butcherbird on hc. It seems that the journo Giles Parkinson is no longer one of Murdock's maggots and has gone freelancing on Business Spectator. If you have an interest in the alternative energy sector Mr Parkinson is one local journo who appears on the ball, and with good connections into the industry.


I am tempted to sign up for his newsletters but am nervous about handing over my email address. Anyone had any experience with the business spectator crowd? Do they appear to hand over email addresses to the junk mail crowds or what?


Anyway the piece basically says that judgement day is fast approaching for Geodynamics, and by extension for the local geothermal sector. I agree: they simply cannot afford to keep coming up with air swings and then expect investors and the governments to keep funding them.


Geothermal's pressure test

Giles Parkinson


Geodynamics has spent an estimated $300 million over the past decade on the development of its cutting edge hot dry rocks geothermal technology in the Cooper Basin. Some time in the next month or so it might find out if it has all been worth it.


It may seem overly dramatic to label the fracturing tests that will be undertaken at a single well over the next few weeks as a make or break for the company.


But that is the way it is being viewed by Geodynamics and its backers. Success will deliver the key to an estimated 6,500MW of clean, base-load power that could be brought to the grid over the next 10 to 15 years; failure will cause the company to undergo a major rethink of its ambitions.


The rest of the geothermal industry also has a lot at stake on what unfolds nearly 5 kms beneath the surface at the Jolokia 1. A good result will bring much needed investor confidence, a disappointing or inconclusive result may have the opposite effect. And proponents of other technologies will be looking on with interest, too. None more so, perhaps than nuclear, which has a weaker case to argue in Australia if geothermal looks likely to deliver on its promise.


Next week, Geodynamics is scheduled to begin a hydraulic fracture stimulation program at the Jolokia well near Innamincka. Water will be injected to a depth of 4.9kms with the aim of finding natural faults in the super-heated granite and opening these up to create a flow of high pressure hot water which can then be exploited to drive a turbine on the surface via a heat exchanger.


It is not the first time such fracture stimulations have been carried out, but no one has done this at the same depth, temperature (280C) and under such extreme pressure (9,000 PSI). Its cutting edge stuff and the team at Geodynamics (many of them ex-oil drillers) are clearly excited. Last week they got their first photos of the deep fractures (sent before the specially created imaging tool melted). No one seems to have sat down since and there is every confidence that this will be a make rather than a break for the company.


Jolokia is located nearly 10kms from the companys previously successful fracturing activities at Habanero. If that success can be repeated at Jolokia, the company argues that this will demonstrate its ability to create heat exchangers at will across its tenement areas unlocking up to 6,500MW of geothermal resources in the Geodynamics tenements and opening up a new energy province in central Australia.


That would lead to a flurry of activity. The company would return to Habanero to drill two more wells and commission the 1MW pilot plant that was delayed by the blow-out in the Habanero 3 well last year. If the pilot plant is successful, the company can then move to make an investment decision on its proposed 25MW commercial demonstration plant, for which it has federal government support to the tune of $90 million, and gain the confidence to tap the market for funds to pay for an expanded drilling program.


The commercial plant would probably not be up and running till around 2015. In the meantime, Geodynamics partner in the Innamincka Deeps project, Origin Energy, will lead its own drilling campaign to see if it can unlock energy from the Innamincka Shallows geothermal heat lying in sedimentary acquifers which are considered easier to exploit. The partners believe there might be around 100MW-200MW of shallow resources in the immediate area. Exploiting these would provide early revenue and be a complimentary energy play to the larger project. But without the longer-term value of the Deeps it is uncertain if this shallow reserve could be economically exploited.


Failure at Jolokia, however, will be a devastating blow. Geodynamics is by far the best funded of Australias growing brigade of geothermal aspirants, with a cash balance of around $70 million, but it needs to tap the market for more money within the next six months to continue its ambitious program.


Other companies need money too. The industry be it pursuing the deep hot dry rock reservoirs or the shallow sedimentary aquifers would prefer not to find itself in a position where its future may be influenced by the success or failure of a single well, but because funding has been so hard to come by from government and the investment community, that is exactly where it finds itself.
