20 July 2016, CSIRO Blog, Supersonic magnesium. It’s used to make our smartphones and cars, and it makes our fireworks go off with a brilliant bang. It’s the third most commonly used structural metal and comprises 2% of Earth’s crust. We are of course talking about magnificent magnesium. Why do we think it’s so magnificent? Well, when magnesium is mixed with other metals it makes stable, super-strong alloys. Not only are these alloys used in our mobile phones and laptops, they are also highly sought after by car manufacturers who are turning to the metal as a solution for making lightweight, low-emission vehicles. Australia is sitting in the driver’s seat to deliver new, improved, ‘supersonic’ magnesium metal and take advantage of our vast untapped reserves of magnesite. So we’ve decided to take the wheel and develop an innovative technology, known as MagSonic, which produces magnesium using up to 80 per cent less energy and up to 60 per cent less carbon dioxide emissions than traditional processes. The process involves heating magnesia (magnesium oxide) with carbon to extreme temperatures to produce magnesium vapour and carbon monoxide. The gases are then passed through a supersonic nozzle – similar to a rocket engine – at four times the speed of sound. This cools the gases in milliseconds, condensing and solidifying the magnesium vapour to magnesium metal. Read More here

19 July 2016, Renew Economy, Frydenberg’s choice: Make a big step forward, or a big step back. The make-up of Australia’s new parliament cut a depressing vista on Monday. There was Pauline Hanson, demanding royal commissions into Islam and climate science, who along with other minor party and independent Senators will most likely hold the balance of power in the Senate, with as many as 7 seats but a minimum of 3. In the government, the Coalition led by Malcolm Turnbull has elevated more conservatives to the front bench. Zed Selseja, a conservative who opposes gay marriage and weekend penalty rates, is minister assisting social services.Hanson gave us a taste of what is to come in an extraordinary debate on ABC’s Q&A, which was punctuated with the sort of ignorance and ideology we often see in the energy sector – see South Australia. Matt Canavan, a conservative who dismisses climate science, is appointed resources minister responsible for the coal industry and building dams in northern Australia. Be under no doubt about Canavan: the only energy that matters to him, he has said often, is cheap energy, dirty or not. Read More here
13 July 2016, Renew Economy, Coalition’s myth about renewables and high electricity prices. Fear of rising electricity prices has been one of the mainstays of the Coalition’s re-election campaign: any efforts to increase the share of renewable energy – as proposed by Labor or even more dramatically by The Greens – or impose some sort of carbon price would end up as a Great Big Electricity Tax. Environment minister Greg Hunt is still at it: “And let me say that equally, we are the only ones that can protect against the electricity price rises that the ALP wants,” he told Melbourne radio 3AW in an interview on Tuesday. So, it should probably be seen as something of an irony that in the week after the July 3 poll, wholesale electricity prices shot to their highest levels on record – in most states averaging nearly double the average price when the carbon tax was in place. The reason, most analysts agree, lies mostly with the soaring price of gas, which has also hit record levels due to the impact of the massive LNG export facilities, and supply blockages in Queensland. But the Coalition is not blameless. Apart from being a hugely enthusiastic supporter of the gas export industry, it brought large-scale renewable energy investment to a halt for three years. As we shall see below, if the estimated 4,500MW of large-scale wind and solar that could have been built in that period had been built, then Australia would likely be enjoying much cheaper wholesale electricity prices today. And while the Coalition has railed against the expense of new renewables, the Labor minority government that runs the Australian Capital Territory has quietly been going about its target of sourcing 100 per cent of its electricity needs from renewable energy by 2020.

11 July 2016, The Guardian, Leaked TTIP energy proposal could ‘sabotage’ EU climate policy. EU proposal on a free trade deal with the US could curb energy saving measures and a planned switch to clean energy, say MEPs. The latest draft version of the TTIP agreement could sabotage European efforts to save energy and switch to clean power, according to MEPs. A 14th round of the troubled negotiations on a Transatlantic Trade and Investment Partnership (TTIP) free trade deal between the EU and US is due to begin on Monday in Brussels. A leak obtained by the Guardian shows that the EU will propose a rollback of mandatory energy savings measures, and major obstacles to any future pricing schemes designed to encourage the uptake of renewable energies. Environmental protections against fossil fuel extraction, logging and mining in the developing world would also come under pressure from articles in the proposed energy chapter. Join the Guardian Sustainable Business Aus network for news and features on the social and environmental impact of business, as well as other exclusive benefits.Paul de Clerck, a spokesman for Friends of the Earth Europe, said the leaked document: “is in complete contradiction with Europe’s commitments to tackle climate change. It will flood the EU market with inefficient appliances, and consumers and the climate will foot the bill. The proposal will also discourage measures to promote renewable electricity production from wind and solar.” The European commission says that the free trade deal is intended to: “promote renewable energy and energy efficiency – areas that are crucial in terms of sustainability”. The bloc has also promised that any agreement would support its climate targets. In the period to 2020, these are binding for clean power and partly binding for energy efficiency, in the home appliance and building standards sectors. But the draft chapter obliges the two trade blocs to: “foster industry self-regulation of energy efficiency requirements for goods where such self-regulation is likely to deliver the policy objectives faster or in a less costly manner than mandatory requirements”.
