16 February 2018, The Guardian, It’d be wonderful if the claims made about carbon capture were true. The International Energy Agency warned this week that, under current energy policies, Australia is unlikely to meet its 2030 climate commitments. While the agency had lots to say about the plunging costs of renewables and the need for strong market signals to encourage the retirement of old and inefficient coal generation, Josh Frydenberg, the federal environment and energy minister, seized on the agency’s support for carbon capture and storage (CCS) – despite the technology’s long history of big promises and meagre results. Last April, Frydenberg visited the newly opened Petra Nova CCS project in Texas. In a video posted to social media the minister, decked out in the obligatory hi-vis vest and hard hat, yells above the noise that the $1bn project is “helping to reduce the carbon footprint by some 40%”. It’d be wonderful if it were true. An estimated 6.2% of the Petra Nova power station’s emissions are captured, compressed and then piped 130km to help extract stubborn oil out of a depleted oil field. In the process, an estimated 30% of the carbon dioxide leaks back into the atmosphere, not to mention the emissions that will ultimately be released when the extracted oil is consumed. Last month, the Minerals Council of Australia was spruiking the “21 large-scale CCS facilities in operation or under construction around the world including in Canada and Texas”. Sounds impressive, if you still trust the MCA’s spin. You shouldn’t – 19 of the 21 projects have nothing to do with coal; there are exactly two “large scale” coal CCS projects globally. And, no, they’re not large. The Canadian project, Boundary Dam, has averaged only 0.591 million tonnes of carbon dioxide over each of its first three years. The $1.5bn project would need to be scaled up 31 times to capture the emissions of New South Wales’s Bayswater power station – an inconceivable investment. Read More here

13 February 2018, Under the Paris Agreement, governments worldwide agreed to hold global warming “well below 2C” and to aim for 1.5C. The inclusion of that second, tougher, goal was a victory for small island states and other countries on the front line of climate change. It was an acknowledgement of fears that higher temperature rise posed an unacceptable threat to their futures. But the vast bulk of research and analysis prior to 2015 centred on the 2C threshold, a more established international target. What would it take to bend the curve to 1.5C? Enter the Intergovernmental Panel on Climate Change (IPCC). The climate science body agreed to produce a special report on 1.5C, summarising all the available evidence. Climate Home News has obtained an early version of the five-chapter report, which is due to be finalised in September. The IPCC stressed it was a work in progress and may change substantially. It is open for review by experts and governments, and may incorporate further studies published by 15 May. Read the draft summary for policymakers in full here. What is clear from the content so far, though, is there is not much time left. Here are the main takeaways. Read More here
12 February 2018, Renew Economy, S.A. to host Australia’s first green hydrogen power plant. The South Australia government has announced funding for what will be Australia’s first renewable-hydrogen electrolyser plant – a 15MW facility to be built near the end of the grid at Port Lincoln on the Eyre Peninsula. The “green hydrogen” plant – to be built by Hydrogen Utility (H2U), working with Germany’s thyssenkrupp – will include a 10MW hydrogen-fired gas turbine, fuelled by local wind and solar power, and a 5MW hydrogen fuel cell. Both will supply power to the grid, will support two new solar farms and a local micro-grid, and will also include “distributed ammonia” that can be used as an industrial fertiliser for farmers and aquaculture operators. The $117.5 million project, which will receive a $4.7 million grant and a $7.5 million loan from South Australia’s Renewable Technology Fund, is being described as a “globally-significant demonstrator project” for the emerging hydrogen energy sector.

12 February 2018, Climate News Network, Hydrogen could see off fossil fuels. Hydrogen is the least talked-about renewable energy but has the greatest potential to replace fossil fuels, both to heat homes and to provide fuel for road transport. The possibility of using hydrogen has been known about for generations, but only in the last two years has it become both practical and financially viable to see it as a large-scale competitor to both gas and oil. Networks of hydrogen filling stations are now being opened in Europe and parts of the US. Batteries for road transport have attracted most of the recent publicity around renewables and have become the focus of many governments with targets for switching away from petrol and diesel, particularly in cities with air pollution problems. But hydrogen has even greater potential because its only emissions are pure water and warm air. Storage potential What has made hydrogen so attractive is that it can use surplus renewable electricity from wind and solar farms by using electrolysers to produce hydrogen. This is a process of passing an electric current through water and converting it into oxygen and hydrogen. The hydrogen can then be stored. Read More here
