18 March 2016, Climate News Network, Emissions standstill boosts Paris hopes. The link between global economic growth and emissions growth has been further weakened as greenhouse gas levels show no increase for the second year in succession. The world continued to make progress towards a low-carbon economy during 2015, according to analysis by the International Energy Agency (IEA). It says analysis of preliminary data for the year reveals that global energy-related emissions of carbon dioxide − the largest source of man-made greenhouse gas emissions − showed no increase for the second year in a row.The IEA announcement will be doubly welcome as some Arctic temperatures continue to warm bizarrely. It comes a day after reports from Fort Yukon in Alaska said temperatures there had reached up to 10°C higher than expected for this time of year. Fatih Birol, the IEA’s executive director, said of the emissions report: “The new figures confirm last year’s surprising but welcome news. We now have seen two straight years of greenhouse gas emissions decoupling from economic growth. Landmark agreement “Coming just a few months after the landmark COP21 agreement in Paris, this is yet another boost to the global fight against climate change.” Significantly, the global economy continued to grow in 2015 by more than 3%, which the IEA says is further evidence that the link between economic growth and emissions growth is weakening. In more than 40 years, it says, there have been only four periods in which emissions stood still or fell compared to the previous year. Three of those – the early 1980s, 1992 and 2009 – were associated with global economic weakness. But the recent stall in emissions comes amid economic expansion. According to the International Monetary Fund, global GDP grew by 3.4% in 2014 and 3.1% in 2015. The IEA says global emissions of CO2 stood at 32.1 billion tonnes in 2015, having remained essentially flat since 2013. Its preliminary data suggest that electricity generated by renewables was critical, accounting for around 90% of new electricity generation in 2015. And wind alone produced more than half of new electricity generation. Read More here

17 March 2016, Science Daily, Biogas: The flexible way to greater energy yield. Biogas is an important energy source that plays a central role in the energy revolution. Unlike wind or solar energy, biogas can be produced around the clock. Could it soon perhaps even be produced to meet demand? A team of international scientists, including microbiologists from the Helmholtz Centre for Environmental Research (UFZ), scientists from Aarhus University and process engineers from the Deutsches Biomasseforschungszentrum (DBFZ), have been studying the feasibility of this kind of flexible biogas production. Among their findings, for example, is the discovery that biogas production can be controlled by altering the frequency at which the reactors are fed. If the intervals are longer, more biogas is produced, according to the researchers’ paper in the Applied and Environmental Microbiology journal. Biogas production has long been a valuable technology, as the constant feed of organic raw materials such as energy crops, manure, sewage sludge, catch crops and plant residues helps produce energy around the clock. The ability to produce energy at a constant rate is a clear advantage over other renewable energy sources such as wind or solar energy, which depend on the wind or sun for production. As a result of this ability, Germany currently has around 8,000 biogas plants installed, with a total electricity output of approximately 4,500 megawatts. Around seven percent of the electricity generated in Germany now comes from biomass. It is hoped that even more electricity will be produced from this source in the future. Scientists from the UFZ, the University of Aarhus (Denmark) and the DBFZ succeeded in increasing the production of methane, the most valuable component of biogas, by up to 14 percent… Read More here
15 March 2016, Renew Economy, Hunt caught out on “peak emissions”, but he may have a cheap solution. As new NASA data reveals global temperature records were smashed by a “stunning” margin in the month of February, new research from carbon market analysts RepuTex has found that Australia’s contribution to curbing global warming could be easier and cheaper than we thought. The study, published on Tuesday has found more than half of Australia’s 2030 emissions reduction target able to be met using “cheap and abundant” domestic abatement – debunking the well established policy myth that the lowest-cost path for Australia was to buy cheap international offsets. The conclusion was reached in a new approach to modelling based on what RepuTex has dubbed the “real world supply cost curve”. It found that more than 300 million credits could be created by local Australian companies over the next seven years at around $1-$4 per credit, while more than 500 million credits could be supplied at less than $20. As RepuTex executive director Hugh Grossman told RenewEconomy in a telephone interview on Tuesday, “that’s a lot” – particularly when you consider the government’s calculations that it needs 900 million tonnes of abatement to meet its emissions reduction 2030 target. And it’s significant, he notes, in that it changes the game for how Australian policy might be designed to achieve emissions cuts: using local emissions reductions, at low cost, without relying on international offsets, all while keeping the cost of compliance low for industry……. Indeed, far from encouraging business and industry to cut emissions, federal environment minister Greg Hunt is busy reassuring us all that Australia’s greenhouse gas emissions actually “peaked” 10 years ago. “I believe that we have reached what is sometimes known as peak emissions,” Hunt told ABC Radio’s AM program. “My best estimate is that we are unlikely as a nation ever to surpass [2005 levels] … In my best judgment, the advice, the information from the department, we reached peak emissions in 2005-06 … and the course of history to come for Australia is that we will continue to be below that figure.” The comments – described by Climate Institute CEO John Connor as “extraordinary”, particularly in light of “the enormous credibility gap in the government’s current policies” – were quickly dismissed by Grossman, who says his company’s analysis of the government’s own data shows Australia’s emissions will continue to grow, with “no peak in sight”.

11 March 2016, Washington Post, United Airlines is flying on biofuels. Here’s why that’s a really big deal. On Friday, United Airlines will launch a new initiative that uses biofuel to help power flights running between Los Angeles and San Francisco, with eventual plans to expand to all flights operating out of LAX. It’s the first time an American airline will begin using renewable fuel for regular commercial operations, and the occasion is part of a bigger movement when it comes to clean transportation in the U.S. The renewable fuel used to power United’s planes will be coming from a Los Angeles refinery operated by AltAir Fuels, which is using the facility to produce both renewable jet fuel and diesel fuel using a technology developed by Honeywell UOP, a major supplier and technology licenser in the petroleum industry. Back in 2013, AltAir and United announced their partnership, in which United will purchase up to 15 million gallons of biofuel over a three-year period. Friday’s launch will be the first application of that agreement. The flights will use a mixture of 30 percent biofuel and 70 percent traditional fuel, and United says that the biofuel will help reduce greenhouse gas emissions by about 60 percent compared with regular fuel. In general, the idea behind renewable fuels is to use a biological source — for example, plant or animal matter — rather than a geological one, like oil. The Honeywell UOP technology that’s being applied at the AltAir refinery can utilize a range of difference sources, from used cooking oil to algae. The technology has been in the works since 2007, when the company was awarded a grant from DARPA to develop green jet fuel, according to Veronica May, vice president and general manager of renewable energy and chemicals at Honeywell UOP. Currently, its technology allows for the production of diesel fuel that can be used in any proportion with existing diesel engines — up to 100 percent. Its jet fuel can replace up to 50 percent of petroleum fuel in existing aircraft. Altogether, both fuels can offer up to about an 80 percent reduction in greenhouse gas emissions compared with traditional fuel, the company says. Read More here
