Aluminium versus Kupfer

The grid scale battery storage market is largely an emerging one, especially when compared to other energy storage systems. Most grid scale batteries are either too expensive or not yet fully tested and understood in a real-life environment - or both. However, pressed by high and rising renewable energy capacity brought online, an increasing number of governments around the world are considering adopting new regulation favouring the commissioning of grid scale storage systems, such as capacity payment mechanisms or mandatory targets for the installation of new storage capacity.

“Many of the new mines and projects today have slightly weaker characteristics than those of the past,” said Vivienne Lloyd, base metals analyst at Macquarie. “That’s why they were not brought online sooner.”

“These two pronounced factors drive the need to substitute ITO with a cost-effective and flexible conductive transparent film,” Zhu says, adding that the new film provides the same degree of transparency as ITO, yet offers greater conductivity.

Rio Tinto PLC hinted it might soon be ready to call an end to austerity, with its top management planning to weigh future growth options in 2015 after two years of aggressive spending cuts

LIMA, Peru--China's Chinalco Mining Corp. International (3668.HK) has approved a $1.32 billion expansion project for its Toromocho copper project in central Peru. The company said the expansion could increase production capacity at Toromocho by 45%. Construction of the expansion project is expected to be "substantially completed" by the second quarter of 2016, Chinalco said.

Saudi Arabia has the largest online capacity of seawater desalination for its energy and domestic needs at 9.2 million cubic meters a day. Next is the United Arab Emirates at 8.4 million cubic meters and Spain at 3.8 million cubic meters.

UK energy regulator Ofgem yesterday announced proposals to change its price control regime to encourage more investment in the power grid.Investment of around £32 billion is needed in the distribution grid over the next 10 years, estimates Ofgem, in order for the UK to meet its low-carbon commitments and bring online a new generation of renewable energy sources.

This is, in fact, the crux of the argument: It isn't enough to simply establish clear rules in a trading center. Governments can only successfully combat speculators if they coordinate their efforts worldwide and remove the cloak of secrecy from their commodities transactions. As long as this fails to happen, the price of copper will remain unpredictable and industry will be at the mercy of speculators. Companies will no longer be able to assume that copper will be expensive when it's scarce and cheap when it's available in abundance. Speculation destroys the basic signaling function that prices have in a market economy, says Heiner Flassbeck, chief economist at the United Nations Conference on Trade and Development (UNCTAD). Although a lot of money moves around as a result of price distortions, speculation doesn't create any real value, says Flassbeck. "The only thing that's created is an illusion of value." Making Life Difficult for Everyone In the end, the popular assessment that speculators are the purest of capitalists is by no means correct. In truth, they are the biggest enemies of the market, because they undermine its central mechanism, the efficient balancing of supply and demand. In doing so, they make life difficult for everyone: for industry, which can no longer predict how expensive its raw materials will be; for consumers, who are forced to bear the costs; and, finally, for copper producers, who face more risk when planning ahead. When the executives at CODELCO in Santiago make investment decisions today, it will be another three to five years before the results become visible. That's how long it takes to develop a new mine or expand an existing mine. The company plans to invest about $15 billion by 2015, but its executives have never been so uncertain about whether their predictions are correct. One thing is clear: Production costs will continue to rise. Now that deposits near the surface, which are easier to mine, are becoming depleted, mining companies are forced to dig deeper and deeper pits.
