Chinese scientists have achieved a breakthrough in “all-iron flow battery” technology that could sharply reduce the cost of storing renewable energy while significantly extending battery lifespan. Lithium costs over 80 times more than iron as a raw industrial material at present. An iron battery may offer a potential solution to one of the biggest bottlenecks in the global energy transition, according to the researchers. A team from the Institute of Metal Research under the Chinese Academy of...
Chinese scientists have developed a method to generate electricity and achieve higher energy efficiency than conventional burning, while producing zero carbon dioxide emissions, by placing coal inside a “battery”. “Coal-fired power” conjures images of heavy pollution, steep carbon footprints and modest efficiency. But a novel, direct coal power technology challenges that stereotype by eliminating combustion entirely and sidestepping the CO₂ emissions that have long defined coal use. A team led...
Hong Kong’s government is under mounting pressure to deliver the Northern Metropolis, announced in 2021, as it approaches the end of its term – less than 15 months and counting. The megaproject, to turn 30,000 hectares (74,132 acres) near the border with mainland China into a centre of international innovation and technology, is to be an engine to drive the city’s economic growth and housing – and the gem of its economic integration with the mainland. We are pressed for time. Beijing has long...
Dubai has completed its first flying taxi station, with commercial operations expected to begin by the end of the year, authorities in the Gulf emirate announced on Thursday. Sheikh Hamdan bin Mohammed, crown prince of Dubai and United Arab Emirates deputy prime minister, visited Dubai’s “first purpose-built electric vertical take-off and landing (eVTOL) Air Taxi Station”, the emirate’s media office said in a statement. The facility, described by the emirate’s authorities as the “first of its...
