The more rigid targets brought around by the latest revision to Germany’s renewable energy act (EEG) in June aims for the country to achieve 65%, instead of the originally targeted 50%, of its electricity consumption comes from renewable sources by 2030. Such stricter targets would mean that, during 2021-2030, the country’s solar photovoltaic (PV) and onshore wind would need over 2GW and 3GW of annual installations, respectively – a highly optimistic target in such an uncertain scenario. Making the targets more stringent may be in line with the broader EU green deal agenda and sustainability objectives, but such a call - made a year before elections - may be fuelled by a political motivation rather than be an achievable goal, says GlobalData, a leading data and analytics company. Somik Das, Senior Power Analyst at GlobalData, comments: “For all of the nation’s renewable sectors to be GHG neutral by 2050, the electricity industry needs to evolve at a much faster pace than has been seen in recent years. Solar PV is now aimed to see a deployment of 18.8GW of capacity from 2021 to 2028, with planned capacity at increments of 1.9-2.8GW. However, with respect to the country’s capacity mix in 2019,

With IMO targeting a 50% reduction in greenhouse gas emissions by 2050, LNG is becoming a natural choice for shipowners in the transition to carbon-neutral fuels. Methane slip regulations are a possibility on the horizon, but Alfa Laval and global Swiss engine developer WinGD have already cooperated on a solution. The Alfa Laval PureCool system is the main component in WinGD’s iCER technology, an option for next-generation WinGD X-DF engines that slashes methane slip and significantly boosts fuel and energy efficiency. Methane slip – the next compliance target? As a growing number of vessels turn to LNG as fuel, many shipowners are concerned about the potential appearance of methane slip regulations. LNG produces less CO2 than other fossil fuels when burned, but a small percentage of methane can slip through the engine without being combusted. Since methane has a higher global warming potential than CO2, even this small source of emissions may come into focus in meeting IMO’s ambitious climate goals. “With IMO aiming to cut greenhouse gas emissions by at least 50% compared to 2008 levels, LNG has a major role as a bridge fuel in moving towards a carbon-neutral future,” says David Jung, Business Development Manager at Alfa Laval. “However, the

Brussels, 7 October 2020: Global economic experts surveyed by EconPol Europe expect economic output to shrink by 4.4 percent in 2020, with projected GDP growth predicted to improve to + 3.2 per cent by 2021. But the forecasts - from 950 experts in 110 countries - suggest that recovery from the economic crash caused by the Covid-19 pandemic will be longer than previously expected, with pre-crisis levels not reached until 2022 in many places.  The experts cite liquidity support for small and medium-sized enterprises and improvements in health care systems as the most effective economic policy measures. Economists from countries where short-time work is in use are most likely to see the measure as a particularly suitable tool. The experts surveyed have widely differing expectations of how long the recovery will take. Taking all respondents together, more than one third (36.4 percent) expect economic output to return to pre-crisis levels in 2022. By contrast, 19.4 percent believe that a full recovery will not set in until 2023. Meanwhile, 24.4 percent are more optimistic and expect a full recovery as early as 2021, with 15.7 percent believing that it won’t arrive before 2023. According to the experts, the most effective economic policy measure is

Professor Hong Feng YANG at the Earth System Science Programme of The Chinese University of Hong Kong (CUHK) recently conducted a comprehensive study of the 2019 earthquake sequence in Weiyuan Shale Gas Field (WSGF) in the southern Sichuan Basin of China. It was found that the 25 February 2019 earthquake occurred at around 1 kilometer below the surface, an extremely shallow depth where earthquakes do not generally happen. There is also evidence that the earthquake was induced by the shale gas production nearby. The findings not only advance our understanding of earthquake physics, but also hold important implications for seismic hazards in shale gas fields. The research article has been published online in Seismological Research Letters. Evidence suggests earthquake triggered by hydraulic fracturing The earthquake occurred at 1:15 pm on 25 February 2019 and had a local magnitude (ML) of 4.9. Two foreshocks with magnitudes larger than 4 occurred nearby, around 20 and 4.5 hours before the ML 4.9 quake. These earthquakes struck Rong County, where shale gas production has been rapidly developed since 2012. To extract oil and gas from low-permeability shale rocks, hydraulic fracturing (also termed fracking), a technique of injecting high-pressure fluid to create fractures in rocks, is commonly

The decarbonisation of the power sector is accelerating through the rapid expansion of low marginal cost renewable generation. As a result, the current electricity market design and the marginal price-based determination of the price of power risk acting as an ever-growing barrier to investment needed to fulfil the net zero ambition, and may need to be reformed. These issues are explored in a new report from Cornwall Insight – The net zero paradox – challenges of designing markets to bring forward low marginal cost resources. The net zero paradox Current electricity market design – which relies on the marginal plant setting the price – means that wholesale prices will increasingly become influenced by zero marginal cost generators, such as variable renewables. Long-range power price forecasts understandably reflect the level of renewables required to reach legally binding climate targets, and the depressing effect of this on projected prices could act to discourage the development of new low carbon capacity, particularly if investment returns rely on wholesale power assumptions. So, this is not just a problem for tomorrow when lower prices are realised, but an issue for today when modelling expected prices. Due to this, Cornwall Insight suggests that there is a strong case for the government
