There is no shortage of gas cartels, or fossil fuels, in Australia

If you want to understand the nature of Australia’s current energy crisis, look beyond the headlines and rhetoric from both sides beyond the fossil fuel fence, and just look at market prices. Australian consumers – both big and small – are duped at gas stations, power sockets and gas pipelines by a large industry that is used to setting its own rules and regulations, and having its own way with markets and governments. Australia is not short on gas, which is now clearly established. But what it also has to admit is that it has nothing short of gas cartel-like behavior, even if the country’s impotent regulators prefer to look the other way. On Monday, something extraordinary happened. On the same day that the Australian government finally dared to call it a bluff, and threatened the imposition of the so-called “gas trigger”, prices fell in both the electricity futures market and the gas market. It’s as if the fossil fuel industry has been caught red-han...

Solar-powered chemistry uses carbon dioxide and water to make raw materials for fuels, chemicals

When light hits the nanowire, it liberates electrons and positively charged “holes” that the electrons leave behind. In the nanowires themselves, the holes oxidize water to protons (hydrogen) and oxygen. Meanwhile, some of the electrons are drawn into the metal nanoparticles, where they break down the carbon dioxide. The molecules recombine into carbon monoxide, hydrogen and methane molecules to form syngas. Credit: Roksana Rashid, McGill University. Solar-powered synthesis gas can recycle carbon dioxide into useful fuels and chemicals, an international research team has shown. “If we can produce syngas from carbon dioxide using only solar energy, we can use this as a precursor for methanol and other chemicals and fuels. This will significantly reduce the overall CO. 2 emissions,” said Ze...
