30 June 2017, Renew Economy, Another blow to CCS, as EU power giants bow out of Dutch project. European power giants Engie and Uniper have withdrawn from a test project to capture and store carbon dioxide generated by one of several major new coal plants in the Netherlands, dealing yet another blow to the prospects of “clean coal” technology, in which the Australian government and fossil fuel lobbyists still hold much stock. Reuters reported this week that the two companies – one of which, Engie, the majority owner of Australia’s Loy Yang B brown coal-fired power station in Victoria’s Latrobe Valley, and who recently closed Hazelwood, – had told the Dutch government they no longer intended to participate in the CCS project, the biggest of its kind in Europe. Holland’s economic affairs Minister Henk Kamp said in a statement he would “examine whether legal steps can be taken to recoup” unspecified subsidies paid to the companies if they had not changed their minds by mid-September. The minister also said that the companies’ withdrawal from the project “changed nothing” in the government’s resolve to develop large-scale CCS demonstration projects. Read More here

29 June 2017, Renew Economy, Coal on limited lifespan as CCS hopes go up in smoke. The coal industry is facing a new crisis point as a group of leading scientists call for the construction of new coal generators to cease within three years, and as the industry’s flagship “clean coal” and carbon capture and storage project went up in smoke in the US. As reported elsewhere on this web site, the US energy utility Southern Co finally gave up on its much-vaunted Kemper coal gasification and CCS project, after costs soared from $US1.8 billion to more than $US7.5 billion ($A10 billion), and it realised it wasn’t going to work. On Wednesday, US time, it announced it would cease operations immediately on the coal component of the project, and just use the asset as a gas generator. Shareholders already saddled with $US3.1 billion of losses face a further $US3.4 billion write down if Southern Co can’t convince regulators to pass those costs on to consumers bills. The spectacular failure of the Kemper facility – more than $US7.5 billion for a 582MW plant, the most expensive in US history per MW – comes amid a renewed call for new coal generation to be stopped in its tracks, and for existing coal generation to be wound back rapidly. In an article in Nature magazine, more than 60 scientists and prominent leaders, including the former UNFCCC secretary Christiana Figures, and former ACTU president Sharan Burrow, now general secretary of the International Trade Union Confederation, say the world has three years to set emissions on the right course. It recommends a six-point plan, including no new coal generators post 2020, accelerating wind and solar and other renewables, retiring all coal-fired generators and boosting electric vehicles. “The climate math is brutally clear: While the world can’t be healed within the next few years, it may be fatally wounded by negligence until 2020,” writes co-author Hans Joachim Schellnhuber from the Potsdam Institute for Climate Impact Research.

29 September 2016, The Conversation, Putting carbon back in the land is just a smokescreen for real climate action: Climate Council report. Just as people pump greenhouse gases into the atmosphere by burning fossil fuels, the land also absorbs some of those emissions. Plants, as they grow, use carbon dioxide and store it within their bodies. However, as the Climate Council’s latest report shows, Australia’s fossil fuels (including those burned overseas) are pumping 6.5 times as much carbon into the atmosphere as the land can absorb. This means that, while storing carbon on land is useful for combating climate change, it is no replacement for reducing fossil fuel emissions. Land carbon is the biggest source of emission reductions in Australia’s climate policy centrepiece – the Emissions Reduction Fund. This is smoke and mirrors: a distraction from the real challenge of cutting fossil fuel emissions.Land carbon Land carbon is part of the active carbon cycle at the Earth’s surface. Carbon is continually exchanging between the land, ocean and atmosphere, primarily as carbon dioxide. In contrast, carbon in fossil fuels has been locked away from the active carbon cycle for millions of years. Carbon stored on land is vulnerable to being returned to the atmosphere. Natural disturbances such as bushfires, droughts, insect attacks and heatwaves, many of which are being made worse by climate change, can trigger the release of significant amounts of land carbon back to the atmosphere. Changes in land management, as we’ve seen in Queensland, for example, with the relaxation of land-clearing laws by the previous state government, can also affect the capability of land systems to store carbon. Burning fossil fuels and releasing CO₂ to the atmosphere thus introduces new and additional carbon into the land-atmosphere-ocean cycle. It does not simply redistribute existing carbon in the cycle.

24 March 2016, Climate News Network, Humans tilt climate books out of balance. Greenhouse gases from cattle, fertilisers, manure and agriculture mean that human activities have turned the land and soil into part of the global warming machine. In the great book-keeping of climate change, scientists have just discovered a big mistake. They have been wrong, they now think, to count on the mountains, the plains, the forests and the grasslands as an agency that slows climate change by absorbing carbon dioxide. It does absorb carbon dioxide. But the chilling news is that the soil itself may be making the world warmer. That is because humans have changed the way the landscape and its living things works, and now – thanks to those other greenhouse gases, methane and nitrous oxides, from cattle, fertilisers, manure and agriculture – the terrestrial biosphere is actually accelerating climate change. Twenty-three scientists from 16 laboratories and institutions report in Nature journal that they re-examined the sums on which climate forecasts depend. They concluded: “We find that the cumulative warming capacity of concurrent biogenic methane and nitrous oxide emissions is a factor of about two larger than the cooling effect resulting from the global land carbon dioxide uptake from 2001 to 2010.” Read More here
