For decades, inefficient batteries prevented a large-scale shift to renewable energy sources like solar and wind, because they couldn’t store enough energy to tide us over when the sun wasn’t shining or the wind wasn’t blowing.
But that’s all changed. Lithium battery technology has evolved to the point where we could feasibly – with progressive leadership – abandon fossil fuels within the next few decades.
Hydrogen storage is another technology that could emerge as a viable alternative to lithium batteries before long, futher fueling the renewable revolution.
David is joined by Professor Jacques Eksteen from the Future Battery Industries Cooperative Research Centre and Dr Terry Humphries, a Curtin research fellow and chemist with a particular interest in hydrogen storage.
