  • CSIRO says emission cuts inevitable

    Professor Flannery also stunned guests at an RMIT University breakfast by questioning whether he should return his Australian of the Year award because he felt torn between speaking out on climate and remaining politically neutral.

    "A couple of years ago there used to be four countries that hadn’t ratified Kyoto," Professor Flannery said. "There was Australia, the USA, Monaco and Liechtenstein. I’m afraid to say that Monaco and Liechtenstein have seen the light, so there’s only two of us left now — the Bonnie and Clyde of climate change, as Al Gore calls us.

    "I don’t know what this means for me, or the office of Australian of the Year — whether it’s better for me to give back the award, and say that it’s simply impossible to continue as things are," he said.

    He later told The Age he was only speaking hypothetically and had no plans to give up his honorary title.

    Professor Flannery’s comments came as Mr Howard stepped up his attacks on Labor and the Greens’ "radical" pledges to cut Australia’s greenhouse gas emissions by 60 to 80 per cent respectively. "I think it is crazy and irresponsible of any political party in this country to commit to a target when you don’t know the impact of the target," he told ABC radio.

    Having previously been dismissive of the need for greenhouse reduction targets, Mr Howard this week declared that setting a long-term target "will be the most important economic decision Australia takes in the next decade".

    He again ruled out setting any targets before the end of May, when a business task group reports back on the economic impact of setting up a national emissions trading scheme.

    Industry Minister Ian Macfarlane also accused the Greens of "political populism" for their call to cut emissions by 80 per cent less than 1990 levels, challenging to them to produce scientific evidence to support their pledge.

    Yet, as an official submission from the CSIRO to the Prime Minister’s emissions trading task group last month pointed out, most international studies now show developed countries such as Australia will need to slash emissions by 60 to 90 per cent by 2050 to avoid "dangerous levels of climate interference".

    The CSIRO also said that a range of economic studies had shown that rapid action to cut greenhouse emissions would only slightly slow economic growth in Australia and globally, with Australia’s economy still expected to more than double by 2040 even with deep emission cuts.

  • Snowy electricity running out of water

    No inflows will see a further fall of 1.5m by June: In addition, it is possible but not yet probable, Lake Jindabyne will drop up to a further 1.5m below MOL to around RL 894.6 metres by late June / early July 2007. The likelihood of Lake Jindabyne going 1.5m below MOL increases if there is no significant inflows from rainfall and noting that environmental flows into the Snowy River are assumed to continue.

    Probability of extra foreshore exposure: As the Lake levels drop, substantial extra foreshore was likely to be exposed, probably in excess of 5 metres if the Lake reached 1.5m below MOL.

    Need to balance usage, conservation: "With no forecast improvement to water inflows in the foreseeable future Snowy Hydro must act prudently to ensure that the water remaining in the Snowy Scheme was used in a balanced way for all stakeholders and that water was conserved for the coming winter and next summer".

    Eucumbene levels set to fall 0.5m by April end: In order to meet the needs of all Snowy water stakeholders including environmental releases and if the current drought conditions continued, then it was likely that by end of April 2007, Lake Eucumbene water levels will drop 0.5m to around RL 1122.0 metres.

    Continued drought may see 5.5m fall in lake levels: In addition, should the severe drought conditions and low inflow pattern continue, it was possible but not yet probable, Lake Eucumbene would drop up to a further 5.5m to around Minimum Operating Level (MOL) at RL 1116.5 metres by late July / early August 2007.

  • Gas giant to pump salty water underground

    Sustainable disposal of salty water:

     

  • Santos had pioneered a sustainable solution to the need to dispose of salty water that accompanies the production of coal seam gas;
  •  

  • In an Australian first, Santos had successfully trialed the injection of produced water into fractured rocks more than a kilometre underground at its Fairview coal seam gas field in southern Queensland. In doing so, the company had adopted a strategy that, at current injection levels, will stop the equivalent of five tonnes of salt a day entering the Dawson River system;
  •  

  • A rise in the level of salinity in the formation water produced with the gas from the Fairview field required a new approach if Santos’ plans to significantly expand gas production were to be achieved.
  • Disposing into Dawson no longer an option: The previous disposal of less salty water into the Dawson River, without causing environmental harm, was no longer an option. The geological zone chosen as the destination for the injected water had no agricultural, economic or cultural value, and already contains water with a greater salinity than that being disposed of.

    An economically beneficial green strategy: Constant injection of 9,000 barrels of formation water a day for 30 years equated to the safe disposal of more than 53,000 tonnes of salt where it will not affect the Dawson River system. And the environmentally sustainable strategy will unlock an additional 100 billion cubic feet of gas. The saline water injection strategy delivers simultaneous environmental and economic gains.

  • Ethanol needs scarce water

    It remains uncertain whether the company proposing the $165 million plant, Gulfstream Bioflex Energy LLC, will succeed. Neighbors have battled the company to a standstill in Webster County Circuit Court over water.

    The case, which could be decided in the next several weeks, has implications for the fast-growing Springfield, Mo., region and potentially elsewhere as citizens groups challenge the ethanol industry.

    Water hogs

    The Great Ethanol Boom rumbling across the Midwest is a positive force in many ways, bringing farmers extra cash for their crops, offering the potential to stem decay in tiny towns, and providing the nation with an alternative to foreign oil. The United States already has 115 ethanol plants in operation, including four in Missouri and seven in Illinois. Another 80 or so are under construction around the country, and many more are planned.

    But all the costs of ethanol don’t get tallied until later. And one of the biggest of those costs, one now generating tension throughout the Midwest and elsewhere, is water.

    The ethanol industry says it takes about 3 gallons of water on average to produce a gallon of ethanol and that recycling and other water-saving innovations will reduce that amount.

    Sometimes that consumption is understated: In Minnesota, one of the few states that require reporting of water use, a state study in 2005 found that ethanol plants used an average of 4.5 gallons for every gallon of ethanol.

    The water drawn for ethanol is a cost borne by communities — or whole regions — and a price sometimes ignored in the planning stages for new plants, experts say.

    In St. Louis, National Corn Growers Association CEO Rick Tolman said his organization has advised ethanol plant builders about the limitations of water. "The water question will not be an impediment to ethanol expansion overall, but it certainly will limit expansion in certain locations," he said.

    The subject has special currency in Iowa, which produces about 30 percent of the nation’s ethanol.

    Richard Cruse, director of the Iowa Water Center at Iowa State University, pointed to potential conflicts when the ethanol industry seeks to use the same pure water that people drink and give to their livestock.

    "I’m not suggesting they’re maniacs running wild not thinking about water," Cruse said. "But with the industry growing so fast and drawing so much water, it can become a risk issue. When we go for three, four or five months with shallow aquifers being drawn down to the point where we have to limit or ration high-quality water, who has the priority?"

    ‘Best place to build’

    Water for an ethanol plant might come from a river, from wells drilled into underground aquifers or from lakes. For the Rogersville plant, the several hundred million gallons of water that would be needed to produce 100 million gallons of ethanol annually would be drawn from the Ozark aquifer, part of a sprawling underground system that provides water from rock formations hundreds of feet under ground.

    Southwest Missouri differs from many locales selected for ethanol plants because little or no corn grows in the Ozarks’ thin soils. Nonetheless, the site near Rogersville, 20 miles east of Springfield, appealed to promoters for other strategic reasons: It is tucked between a busy four-lane highway, U.S. 60, and a railroad line, perfect for hauling in corn and dispatching tank cars full of ethanol. There’s a natural gas pipeline nearby to power the plant.

    Promoters point to a state report a decade ago that estimated that more than 12 trillion gallons of water lay beneath Webster County. That would be enough, they say, to operate the plant for thousands of years.

    "Webster County is the best place to build the ethanol plant, based on those figures," Bryan Wade, a lawyer for the Gulfstream partners, argued last month in court.

    Promoters have not identified principal funding sources other than to say they have been working with investors in New York. One of the Gulfstream founders is Greg Wilmoth, a trucking company executive from Mount Vernon, Mo., who has drawn extra attention because of family connections: He is a cousin, once removed, of the state’s most prominent ethanol booster, Gov. Matt Blunt.

    On the witness stand last month, Wilmoth described one significant benefit of the plant: 40 to 50 jobs paying between $30,000 and $35,000 a year. Later, he was asked by the lawyer for those suing to stop the ethanol plant what would happen if it gets built and the groundwater system fails.

    "I’ve got a $165 million white elephant," he replied, a predicament that the company does not expect to confront.

    Relying on rain

    The Rogersville plant is one of three in Missouri that Gulfstream Bioflex says it wants to build. Another would be in Monroe County, near Hannibal, where water is not an issue because it would draw from an aquifer replenished regularly by the Mississippi River. A location for the third has yet to be identified.

    James Kaiman, a St. Louisan and former chemical company executive who recently joined the Gulfstream Bioflex enterprise as its president, asserted that people in southwest Missouri who oppose the plant — about 400 or so neighbors and other opponents have signed petitions — constitute only a fraction of the county’s 33,000 inhabitants.

    "They look at it and say, ‘I don’t want this in my backyard.’ It’s a little surprising," he said in an interview.

    Landowners near the site of the proposed plant say they have ponied up $100,000 since last fall to fight the plant. In December, they won a temporary restraining order on construction after arguing in court that water consumption and plant pollution would constitute a public nuisance.

    Now, after the two-day trial last month in Webster County Circuit Court, a decision is expected soon. Both sides brought paid experts to court to buttress their opinions about the sufficiency of water in the Ozark aquifer.

    Some underground aquifers, particularly those near rivers and streams, readily refill after depletion. By contrast, the Ozark aquifer is classified as a confined aquifer, which means that it has little connection to other underground water sources and must rely on rain and snow to become recharged.

    Nobody can say for sure what will happen deep underground with such continuous pumping and how readily the Ozark aquifer can recharge itself. The two sides in the debate offer competing perspectives on whether there will be enough water to go around.

    But trends are already troubling.

    Dropping water tables

    As a result of over-pumping in the region, a "cone of depression" — a lowered water table from pumping — began forming in the 1970s and has continued to grow, according to a groundwater study two years ago at Missouri State University.

    In response to declining water levels in the early 1990s, Springfield completed construction of a 40-mile pipeline and pumping station in 1996 to deliver water from Stockton Lake in Cedar County. But other towns, among them Nixa, Ozark, Republic and Battlefield, continue to rely on water from the Ozark aquifer.

    According to the Missouri State study, the aquifer outside of Springfield dropped as much as 140 feet in places from 1987-2004 — but in some places water levels remained constant or even rose.

    Meanwhile, rural dwellers have reported well problems that began showing up a few years ago. More than half of nearly 300 well owners in northern Greene County reported problems with their wells in a survey five years ago by the Watershed Committee of the Ozarks, a nonprofit dedicated to preserving water supplies in the region. Local landowners and well-diggers say the problems have worsened.

    Bob Schulteis, a water specialist at the University of Missouri Extension, was the chairman of a Webster County-appointed committee that concluded that the plant could harm both the quantity and quality of local waters.

    "Already we’re seeing the water tables in that location dropping, so adding an additional high-demand well or two at the location would likely accelerate that," he said.

    Nathan Jones, whose business sells solar-powered pumps, said his Greene County water well situated above the Ozark aquifer had dropped at least 140 feet in nine years.

    ‘Our dreams all exploded’

    Gulfstream Bioflex says it would drill wells deeper into the aquifer or supply better pumps if landowners around the plant have problems. New wells cost about $10,000 in Webster County.

    James Kaiman, the company’s new president, said he’s confident it won’t come to that.

    "We wouldn’t be doing this if we felt that we were going to be impacting neighbors," he said.

    William McDonald, who is representing opponents of the plant, argued that water uncertainties also threaten the plant. "There is no Plan B," he said. "If the groundwater system fails, not only will it be catastrophic for people in the area, it will be catastrophic for Gulfstream Bioflex."

    Besides blocking the plant thus far, the resistance by neighbors also has prevented closing on the company’s purchase of the 252-acre Porter family farm, for $12,000 an acre in a county where the typical price for an acre of land is $2,500 to $3,000. Larry Porter, who has been shunned by some of his neighbors since plans for the plant were announced last fall, declined to be interviewed.

    Opponents are nervous about what comes next if Gulfstream Bioflex wins the court case: The company would be dealing with the Missouri Department of Natural Resources, which handles permits for ethanol plants in the Blunt administration.

    Wilmoth, Gulfstream’s vice president, is not the only Blunt relative to plunge into the ethanol business. Andy Blunt, the governor’s younger brother, was identified last year as an investor in another Missouri ethanol venture.

    Matt Blunt, like other Midwestern governors, has championed biofuels expansion. He backed the state law requiring 10 percent ethanol in fuels starting next year, supported paying off unfulfilled state financial commitments to ethanol producers, and lobbied for a pending federal government rules change that would relax air pollution standards for ethanol plants.

    Blunt spokeswoman Jessica Robinson said his administration would not stint on regulating the industry in Missouri. Family ties have nothing to do with his ethanol policies, she said.

    "His support of ethanol is nothing new to anyone, whether they be Missourians or relatives," she said.

    Meanwhile, people who live near the proposed plant in Rogersville envision drying times — and perhaps crying times.

    "Our dreams all exploded at one time," Dean Alberty remarked while driving to his family’s Red Oak Bed & Breakfast near the proposed plant. Alberty, whose family is among those who sued to stop the plant, has put off building a new home until the case is decided.

    Added his wife, Maja: "Ethanol is not a bad thing. But you can’t put it where it will take our water."

  • Renewable energy numbers released

    Household electricity bills would rise by just $1.23 a week if a quarter of Australia’s energy came from renewable sources, a report has found.

    The report by three green groups says setting a renewable energy target of 25 per cent by the year 2020 would deliver more than 16,000 new jobs, slash greenhouse gas emissions by 69 million tonnes and generate $33 billion in investment.

    Although the average power bill would rise by $64 a year, continuing to rely on current power sources would cause prices to jump by $234 a year.

    The study, A Bright Future, was released Monday by the Australian Conservation Foundation, Greenpeace and the Climate Change Action Network.

    It warns Australia is missing out on the economic benefits of renewable energy that are flowing to California and European nations which have boosted their renewable energy targets.

    In 1997, the federal government set a mandatory renewable energy target of two per cent, on top of existing supply.

    At present, about 10 per cent of Australia’s energy comes from renewables like wind, solar and hydro.

    "With current policies, (Australia’s) electricity emissions will reach 260 million tonnes by 2020, more than double 1990 levels," the report said.

    "Generating a quarter of our electricity from renewable energy and reversing electricity growth from 2010 onwards by ambitious energy efficiency measures would reduce overall electricity emissions to 160 million tonnes.

    "The reduction of about 100 million tonnes, compared to business as usual, would be equivalent to removing all the road transport in Australia.

    "Provided we put Australia on track for sustained renewable energy development, costs should fall to below the cost of fossil fuels over the next 15 years."

    Under the plan, coal’s share of power generation would fall from three-quarters to 59 per cent, drastically reducing greenhouse emissions.

    The study said allowing Australia’s energy use to continue rising would ultimately cost the country far more than switching to renewable sources now and becoming more energy-efficient.

    Australia was blessed with abundant renewable energy resources yet was lagging behind countries like Germany, which was less windy and received less sunlight.

    Greenpeace campaigner Mark Wakeham said Australia should be a world leader in renewable energy.

    "Yet due to current government policies, we’re throwing away our competitive advantage and renewable companies are moving offshore," he said.

    The European Union has set a renewable energy target of 21 per cent by 2010 and California is aiming for 33 per cent by 2020.

  • Citigroup calls for end to coal

    Disappointingly, Labor’s new environment spokesperson Peter Garrett, has chosen to kick off his tenure by restating his predecessor Anthony Albanese’s proposition that we can reduce CO2 emissions whilst continuing to use coal. Citing Australia’s coal resources as a “blessing”, Garrett’s endorsement of the ‘clean coal’ myth made it clear how far the ALP line is from the environment movement’s. His comments were in stark contrast to his successor as current ACF President, Ian Lowe. Speaking in Newcastle last Monday night, Lowe stated the obvious: “The only way the world can meet its carbon reduction targets is to burn a lot less coal”, and endorsed as “wise” the resolution of Newcastle Council to cap coal exports and introduce a ban on new coal mines in the Hunter Valley.

    Garrett’s position is the standard ALP line; that you can somehow massively expand Australia’s coal export industry and continue to rely on coal for the majority of our domestic power yet still reduce CO2 emissions. The inadequacy of this position is revealed by looking at the policy of the NSW Government on greenhouse gas (ghg) reductions. The Premier, Morris Iemma, has committed to stabilising ghg emissions at 2000 levels by 2025. Given that we are near to those levels now this means that, in the next 19 years, emissions cannot increase. In effect, this is a de facto moratorium on new coal-fired power stations in NSW. Indeed, when you factor in population growth; in new vehicles driven by Labor’s car-centred transport policies; and routine growth in emissions, it may be impossible to meet the 2025 target without actually reducing use of coal-fired power. Moreover, it is inevitable that the Iemma Government’s target will be superseded by more ambitious targets in the future as governments get serious about tackling climate change. To only achieve a stabilisation by 2025 would lead to a climate change induced nightmare.

    As far as Australia’s coal exports go, both major parties commit rhetorically to engaging in an international process, which will lead to deep reductions in ghg emissions. Yet any international regime that does achieve this will inevitably put pressure on, and indeed reduce use of, coal. How can it not? Coal is the most carbon-intensive of the fossil fuels and reducing reliance on coal through efficiency, switching to gas or developing renewables are among the easiest and quickest ways to reduce C02 emissions from the electricity sector.

    The standard response to this of course, is that so-called ‘clean coal’ will solve the problem. Firstly, clean coal is a furphy, the equivalent of ‘healthy cigarettes’. Coal is dirty, as even the Prime Minister has begun to acknowledge. And the claims being made by the coal industry that the technology to bury emissions is nearly available do not stand up to scrutiny. The World Coal Institute recently conceded that by 2020 it was likely that only nine projects using carbon capture and storage (CCS) would exist. That’s too little too late. We have about 10 years to start reducing emissions dramatically or we will likely pass the `tipping point’ at which dangerous climate change will be unavoidable. By 2020 we need to have our emissions at about 30% below 1990 levels. Yet we may not even know if CCS works by then and, as the United Nation’s expert panel on climate change stated in their recent special report on CCS, commercialisation will take even longer. So CCS is simply not even available during the next critical decade, and may never prove to be viable. To use it as political cover to keep opening new coal mines, expanding our coal exports and refusing to support efficiency and renewables is unconscionable.

    The real question now is not whether we have to quit coal, but how quickly we can make the transition and how we can ensure those people dependent on coal for jobs and income are not left stranded. That, coupled with ambitious policies to stop energy wastage and promote renewables, will see Australia start to use the other resources with which we are “blessed”: sun, wind and ingenuity. Climate change can be solved, but not without quitting coal. The time to move on is now.
