The world is quickly abandoning coal, the dirtiest of fossil fuels. But that’s not the end of the road for coal mines—in many countries they’re coming back to life as solar farms. Over the weekend, the world’s biggest floating solar project began operating in the eastern Chinese city of Huainan, which accounted for nearly 20% of the country’s coal reserves in a 2008 estimate. The 150-megawatt (MW) project consists of panels floating on a lake formed in a collapsed coal mine, according to (link in Chinese) the state-owned power company China Three Gorges Corporation, which began building the project in July. The company said it had spent 1 billion yuan ($150 million) on the project, which it expects to come into full use in May 2018. At full capacity, it’ll be able to power around 94,000 homes. The project sets a new record in its class and will quickly eclipse another floating solar power project in the same city that became the world’s biggest such farm in August. The latter, which can supply electricity to 15,000 homes, also sits atop a former coal mine.

An Oxford solar panel entrepreneur who believes his unique designs are about to revolutionise the energy industry has been given a major endorsement. Henry Snaith has tied for first place in this year’s Clarivate Analytics’ ranking of highly-cited researchers, with 29 ‘hot papers’ on solar cells. he significant value the academic community has placed on Henry’s research, quantifies the opportunity perovskite solar cells presents, to dramatically transform solar cell efficiency and economics, of which Oxford PV is at the forefront of commercialising.” Oxford PV is developing a new type of solar panel which Professor Snaith says has the capacity to make Hinkley Point nuclear power plant redundant before it is built. The panels use metal halide perovskite crystals as a semiconductor, which he says are more efficient than other materials.
