Uni renewable plan scores $3m
The University of New South Wales has won a $3 million NSW Government award for its development of technology claimed to store renewable energy without using batteries.
The uni’s “integrated energy storage solution” is claimed to be able to turn excess renewable energy into a gas which can be stored and then burnt to generate electricity.
Zhao Yang Dong, professor of energy systems at UNSW, says its development uses excess electricity to convert water into hydrogen. With the addition of carbon dioxide, it can then be turned into a gas which can be stored and later reused.
“Batteries can be turned on instantly, so they still have a place in an energy system. But gas can outlast a battery,” Dong said this week.
He said the uni is also looking to develop software and infrastructure for “integrated energy networks”, which manage supply of electricity to consumers using a large number of different energy sources.
