ANU team cracks solar thermal efficiency of 97% – a world record  

ReNew Economy has an article on a new efficiency record for solar thermal power - ANU team cracks solar thermal efficiency of 97% – a world record

The ANU team, whose CST technology harnesses the power of the sun using a 500 square meter solar concentrator dish, made the breakthrough by redesigning the system’s receiver in a way that halved its convection losses and boosted its conversion of sunlight into steam from 93 per cent to 97 per cent.

According to the ANU’s Dr John Pye, the new design could result in a 10 per cent reduction in the cost of solar thermal electricity. “Ultimately the work in this project is all about reducing the cost of concentrating solar thermal energy,” he said. “Our aim is to get costs down to 12 cents per kilowatt-hour of electricity, so that this technology will be competitive.
