Northern SA a leader in renewable energyNorthern South Australia has become a leader in the development of renewable energy in Australia with more wind and solar developments than any comparable region in Australia.For a dirty technology such as ISCG to be added to the region's energy resources is unnecessary and a betrayal, even a crime. As illustrated by the images on the right, South Australia's (and Australia's) energy futures could be, should be, and increasingly will be, in renewable energy. The growth industries are:
The implications of in-situ coal gasificationIn-situ gasification (ISCG) has been trialled at Leigh Creek in the Northern Flinders Ranges (in the same coal beds that were used to supply the Port Augusta power stations before they were closed).In terms of carbon intensity (the amount of greenhouse gasses released per unit of useful energy obtained) ISCG is worse even than mining and burning coal. It is the least attractive option for producing energy from the point of view of greenhouse emissions minimisation. With ISCG the coal is partially burned underground, releasing carbon dioxide, carbon monoxide, methane and hydrogen; the carbon dioxide and methane are greenhouse gasses. The intention is that these gasses will be collected and later the carbon monoxide, methane and hydrogen will be burned to obtain useful energy, releasing carbon dioxide, and steam. A major risk of the process is that some of the carbon dioxide and methane generated in the coal seam is likely to leak into the atmosphere. Methane is a very active greenhouse gas, far more active than carbon dioxide.
It would be a serious backward step, ethically and environmentally, for ISCG to be used in
South Australia's energy future.
The link between Linc Energy (Queensland) and Leigh Creek Energy (South Australia)In November 2018 Angelique Donnellan wrote an article for the ABC titled "Is Leigh Creek's controversial energy trial a lifeline for a dying town or an environmental hazard?" Some quotes from the ABC article:"Earlier this year, a company called Linc Energy was found guilty of causing wilful and unlawful serious environmental harm at Chinchilla on Queensland's Darling Downs.Mr Peters was quoted as saying: "I don't believe there is environmental damage caused at Chinchilla"The Queensland environment minister described Chinchilla as the biggest pollution event in the Queensland's history, the court fined Linc Energy $4.5 million, but Mr Peters doesn't believe there was any damage; draw your own conclusions. Taxpayers pay $31 million to clean up messLydia Lynch reported in the Brisbane Times, 2019/06/16, that Queensland taxpayers were having to spend almost $31 million to clean up the pollution left by Linc Energy.
Open letter to Dan van Holst PellekaanMr van Holst Pellekaan is Member of the South Australian House of Assembly for the seat of Stuart, which includes Leigh Creek, and is South Australian Minister for Energy and Mining in the Liberal Marshall Government.I sent the below to Mr van Holst Pellekaan as an email on 2019/02/20. "Three simple and closely related questions, if I may. As you would be well aware, if we are to combat climate change we must reduce the carbon intensity of our energy supply. With South Australia's very successful adoption of renewable energy the state's overall carbon intensity has been greatly reduced. The response below was sent 2019/03/11(Either I did not receive it or I lost track of receiving it.)"Thank you for your emails of 20 February 2019 regarding carbon intensity and in-situ gasification (ISG) at Leigh Creek.
Second letter on this subject to Minister van Holst PellekaanThe following email was sent on 2019/06/17:"Dan, I sent you an email asking questions about the proposed in-situ coal gasification back on 2019/02/20, to which I have not received a reply [A reply was sent – see above].I received an automatic response showing that my email had been received. Reply from Minister Pellekaan, received 2019/07/06(Translated from PDF to txt online using PDF2GO)"Thank you for your email dated 17 June 2019 regarding your previous emails sent, on 20 February 2019, in addition to posing further questions relating to the Underground Coal Gasification (UCG) trials at Chinchilla, Queensland. Environmentally responsible governments?The South Australian Rann Labor Government (2002-2011) and the following Weatherill Government (2011-2018) have received quite a bit of credit for the state's adoption of renewable energy, and it is true that unlike a number of other state and federal governments, they didn't oppose the development of renewable energy.But the fact that the Weatherill Government encouraged fracking in South Eastern South Australia and supported the investigation of the possibility of ISCG in the Leigh Creek area suggest that the Weatherill Government at least may have been opportunistic rather than ethical. So far as I know both Labor and Liberals have been comfortable with oil drilling in the Great Australian Bight. It is noteworthy that the Liberal-National coalition Marshal Government passed a bill legislating a moratorium on fracking in the South East of South Australia in October 2018. Louise Horobin wrote an article in the Border Chronicle, 2018/10/26. She wrote "Limestone Coast Protection Alliance chairperson Angus Ralton congratulated the community and local politicians for continuing to fight for legislation reform." Mr Ralton was quoted as saying: “This is a well deserved outcome for the community that has fought so hard. Thanks must go to our local independent MP, Troy Bell for moving this Bill and to Nick McBride for getting the Libs on board. We'd also like to thank Mark Parnell and fellow Greens in the Upper House as well as SA Best whose support was crucial in getting this Bill through.” While there can be no doubt at all that the federal Liberal-National coalition governments of Prime Ministers Abbott, Turnbull and Morrison were anti-environment and pro-coal, while the federal Labor Opposition was more environmentally responsible, it would seem that the situation in South Australia is more open to question. |
