12 September 2017, Renew Economy,AEMO: Our advice was pretty straight forward, we need dispatchability. As the federal Coalition continues to push the case for an ageing, unreliable, and slow moving coal generator to maintain energy security in the 2020s, the Australian Energy Market Operator has underlined its advice to the government last week: it wasn’t a push for more baseload. “We need flexible capacity that can be switched on and off, and we need to transition to a new generation of Australia’s principal energy market institutions, and the newly-formed Energy Security Board. “Our advice was fairly pragmatic,” Zibelman said. “We are concerned that on a 45°C day if we lose a generator (which AEMO has said is quite likely) we want reserves in the system to be able to respond. “In our report we identified the fact that with amount of variability (from solar and wind energy and electricity usage) is changing rapidly, we need resources that can change rapidly. “That may be different to traditional baseload resources, which do not move a lot. It doesn’t mean baseload is bad, it’s just that we need a different portfolio. (Baseload) may not be able respond in the time period we need it to respond.” Sound like Liddell? Not really. The plant owner AGL Energy has made it clear that Liddell is old, increasingly unreliable, expensive to maintain, prone to unexpected outages and can’t be relied upon at times of peak demand, particularly as temperatures rise. Zibelman’s comments, like the two AEMO reports it released last week, contrast starkly with the Coalition government’s contention that AEMO had insisted that rapid action was needed, and that that rapid action must mean that Liddell’s life span must be extended. Zibelman made it absolutely clear that her preference was for fast, flexible technologies, both in supply and demand, and bother in front and behind the meter. Importantly, it had to be technology that the market operator could rely upon. Read More here

11 September 2017, Renew Economy, AGL calls Coalition bluff on Liddell, focuses on solar, wind and storage. AGL Energy has called the bluff of the federal Coalition over the future of Liddell, pointing out that the ageing coal plant is unreliable, and stating its clear focus is on replacing the capacity with renewable energy and storage. CEO Andy Vesey agreed to take the government’s proposal to extend the life of the coal generator or sell it to the company board, but that commitment is likely to be nothing more than a face-saver for a Coalition government pushed into the realms of stupid by its desperation to appease its right wing and the Nationals. There is no way the AGL board would approve a proposal not favoured by Vesey, and the CEO clearly has other plans afoot, and they are all about renewables, peaking plants and storage. “Short term, new development will continue to favour renewables supported by gas peaking,” Vesey said after a meeting in Canberra with prime minister Malcolm Turnbull, energy minister Josh Frydenberg, and deputy prime minister and Nationals leader Barnaby Joyce. “Longer term, we see this trend continuing with large-scale battery deployment enhancing the value of renewable technology. In this environment, we just don’t see new development of coal as economically rational, even before factoring in a carbon cost,” Vesey said in a statement. And he made clear in this statement that Liddell would retire, as planned. “Following today’s meeting with the Prime Minister, we have committed to deliver a plan in 90 days of the actions AGL will take to avoid a market shortfall once the Liddell coal-fired power station retires in 2022.” And for good measure, he tweeted that line …. “once the Liddell coal-fired power station retires in 2022.” Read More here
11 September 2017, Renew Economy, The Turnbull-Frydenberg investment bank: Bullying, cronyism and Captain’s picks. Bullying, cronyism and Captain’s picks instead of policy. There is almost universal agreement that carbon policy is or should be a Federal issue. That is clearly something that the Federal Government should be involved in as it involves Australia’s international status and obligations. But that is the one area that the Federal Government is not touching. Despite Finkel, despite our COP 21 obligations, the Federal Government does nothing. No electricity policy, no vehicle emission standards, no policy in other areas of the economy responsible for half of Australia’s emissions. Perhaps the very worst thing, of the many to choose from, about the Liddell negotiation is the gross misuse of the AEMO report. This is only possible because the media is too busy, to put it kindly, to do its homework. The definition of a “problem” is when forecast “Unserved Energy (blackouts)” exceeds the desired reliability standard. That is not the whole story, but if you want one metric, it’s that. unfortunately, AEMO didn’t draw its graph relating to NSW all that clearly. We have attempted to do better, using the .xls data that AEMO provides. AEMO does not forecast a problem and if more renewables are built, the standard will be easily met. Read More here
6 September 2017, IOL Motoring The hydrogen vs battery car debate is far from over. London – With hybrid and full electric cars now becoming mainstream, it may seem as though the early debate between hydrogen and battery power is over. But batteries have considerable drawbacks. They’re heavy, they’re expensive, they require the extensive use of rare earth metals, and the production of lithium-ion batteries is itself an energy-intensive process that creates considerable emissions. Despite the progress made in EV technology, most car companies are predicting it will be a long time before batteries become dramatically cheaper or lighter than they are today. Speaking to investors last year, Stefan Juraschek, vice president of electric-powertrain development at BMW, said the car maker needed to “walk through the valley of tears” of funding highly costly research and development in order to make significant progress on battery power. Electric cars require energy straight out of the mains, which could come from power plants that are not using renewable technology. In Tesla’s home state of California, 60% of electricity was provided by coal and gas power stations in 2015, while only 14% came from wind and solar. China is investing more in renewables than any other nation yet derived roughly 72% of its electricity from coal power in 2014. In a hydrogen fuel cell car (FCEV), electric motors power the wheels but the energy is supplied through a chemical reaction between hydrogen and oxygen in the fuel cell. Unlike the rare and heavy components needed to build a battery, hydrogen is the most abundant and lightest element in the known universe although it is worth noting that hydrogen drivetrains also require rare materials.
