Study shows renewables cheaper than fossil fuels across Middle East, North Africa region

The study, published last month in Energy Strategy Reviews, is believed to be the first to look at how renewable energy generation might meet hourly loads across MENA.The study looks at several scenarios, including establishing fully renewable electricity grids independently in most MENA countries, or having the whole area interconnected by high voltage DC transmission links. A third scenario looks at the effect of adding loads from seawater desalination and the industrial gas sector onto a MENA-wide interconnected electricity system.The researchers estimated the levelized cost of energy (LCOE) arising from fully renewable electricity systems would vary between €40.30 and €52.80 ($43.53 and $57.04) per megawatt-hour, depending on the scenario. The estimated business-as-usual LCOE is €118.60 per megawatt-hour, and that’s without including the cost of greenhouse gas emissions.Unsurprisingly, the most expensive scenario was the one without interconnections between countries. Evening out supply and demand with a MENA-wide transmission network would cut LCOE from €52.80 down to €48.30 ($52.16) per megawatt-hour, the study found.Importantly, though, the research also showed that coupling the desalination and industrial gas sectors to renewable energy generation could cut LCOE even further, reducing it by 17 percent compared to simply having an interconnected grid. The integration would be achieved using power-to-gas technology, with 90 percent of electrical energy generation coming from onshore wind and large-scale PV.[Jason Deign]More: Study: Middle Eastern countries would save money by ditching fossil fuels in power mixlast_img read more

Singapore sends Turkish Airlines flight back empty after coronavirus case

first_imgA Turkish Airlines aircraft was flown back to Istanbul without any passengers on Thursday on orders from authorities in Singapore after a passenger who had arrived on the same plane on Tuesday tested positive for coronavirus.Singapore’s aviation regulator said that the three pilots and 11 other crew of flight TK54 that had arrived on Tuesday were on the return flight to Istanbul, where they would be placed in quarantine.”The crew had come into close contact with a passenger on flight TK54 who subsequently tested positive for COVID-19,” the Civil Aviation Authority of Singapore (CAAS) said in a statement on Thursday. “The Ministry of Foreign Affairs is in contact with the Turkish Embassy, which has confirmed that the crew will be quarantined upon arrival at Istanbul,” CAAS said.Singapore’s transport ministry said in a statement on its website that authorities had begun tracing passengers on flight TK54 that may have had contact with the infected person.The Straits Times newspaper said 200 passengers were affected. It issued a correction to an earlier report, cited by Reuters, that all of them had been tested for the coronavirus.Turkish Airlines did not respond immediately to a request for comment on the number of passengers on board.Singapore had 112 confirmed cases of coronavirus, which started in China, but a large majority of the patients in the city-state have recovered and been discharged from hospital.Topics :last_img read more
