For years, the ‘duck curve’ of low daytime demand due to cheap solar power has challenged energy planners. California is showing the solution is storage.
China’s two largest EV battery makers are pledging to slash the cost of their batteries this year. Behind the pledge is a cost war – and new battery chemistries.
The temptation to justify critical minerals mining at all costs is a dangerous fallacy. The social and environmental impacts of poorly mined critical minerals are dire.
Lithium-ion battery fires are becoming increasingly common as electric vehicles spread, and are hard to extinguish. A new approach uses an electrolyte based on a commercial fire extinguisher.
Australia leads the world in rooftop solar per head. Can this small-scale power source be the secret weapon to fire up our struggling transition to net zero?
If big money is going to invest in clean energy and technology, the rules have to be clear. Australia’s launch of a green finance strategy last week was a good start but there is further to go.
Storing energy in large pumped hydro schemes sounds simple. But engineering and terrain challenges have put Snowy 2.0 well off track – while grid-scale batteries get better and better
Lithium-ion batteries power many electric cars, bikes and scooters. When they are damaged or overheated, they can ignite or explode. Four engineers explain how to handle these devices safely.
We’ll need some new transmission lines to make Australia’s grid ready for the green energy shift. But there are clever ways of making more use out of our existing network.
