The case for hydrogen as a fuel has been well made but there has been little investment to bring it to scale.
The energy required to power the massive, factory-sized data centres that computers rely on already consumes 5% of global electricity. And that energy load is doubling every decade.
Moving to a future powered mainly by renewable energy will be crucial if we are to stay within the global warming limits set out by the Paris Agreement.
A laser-driven technique for creating fusion that dispenses with the need for radioactive fuel elements and leaves no toxic radioactive waste is now within reach, says a UNSW physicist.
When it comes to energy, governments are lacking the expertise that engineers can provide, writes Jenny Stewart.
UNSW has joined a coalition of prominent Australians to ensure the country's transition to a clean energy future.
All UNSW's top news stories, from quantum computing dollars to a warm welcome for new Deans and dignitaries.
UNSW scientists have developed an efficient oxygen-producing electrode for splitting water that can be scaled up to produce hydrogen – a clean energy fuel.
Solar engineers from UNSW's Australian Centre for Advanced Photovoltaics have set a new world-record in solar energy efficiency, achieving an electricity conversion rate of over 40%.
UNSW academics are available to comment on what's shaping to be one of the most significant G20 meetings in many years.
