What’s at stake at COP26? Your climate primer

This weekend, world leaders will meet in Glasgow to discuss the acute social, scientific and economic challenge we face. With so much information flying past, it’s easy to lose track of the science and technology. What’s our current trajectory? Could we suck carbon dioxide out of the atmosphere? Why is everyone so interested in hydrogen … Continue reading What’s at stake at COP26? Your climate primer

Has our hydrogen future arrived?

Hydrogen has been discussed as the fuel of the future in recent times, with state and federal governments aiming to see renewable hydrogen at a competitive price by 2030. But some companies – most notably Fortescue Future Industries (FFI), an offshoot of mining giant Fortescue Metals Group – have more ambitious dates in mind. FFI … Continue reading Has our hydrogen future arrived?

Future power strategy: electrify everything

When Hurricane Ida slammed into the lowest-lying areas of Louisiana in August of 2021, many expected that the most powerful storm to strike the area in more than a century would produce an ugly rerun of the storm that struck exactly 16 years earlier: Hurricane Katrina. In 2005, neglected levees, overwhelmed by a massive storm … Continue reading Future power strategy: electrify everything

“Technology, not taxes”? Experts say that existing renewable technology should be used immediately

Existing technology and new policies are the keys to a net-zero emissions future, according to the Australian Academy of Technology and Engineering (ATSE). In a statement released today, the academy of independent technology experts voices its support for more ambitious emissions reduction targets in Australia, immediate deployment of low or no-emissions technology, and a national … Continue reading “Technology, not taxes”? Experts say that existing renewable technology should be used immediately

Turning the tide on wave energy

Ocean waves have long been heralded as a source of energy, but so far it’s been difficult to turn this energy into electricity in a commercially viable way. A team of Australian and Chinese researchers has advanced the cause, developing a device that is twice as effective as any existing technologies. “Our prototype technology overcomes … Continue reading Turning the tide on wave energy

Renewables make it into the grid better with AI

In a highly competitive market, all energy generators rely on highly accurate predictions of how much electricity they’ll be able to make. Australian researchers have figured out a way to improve these predictions for wind and solar farms, using artificial intelligence. The National Energy Market – “the grid” – requires automatic forecasts every five minutes … Continue reading Renewables make it into the grid better with AI

CSIRO’s renewable hydrogen initiative

CSIRO has launched a $5 million program to boost international collaboration on clean hydrogen research. The program will be run by the CSIRO’s new Hydrogen Industry Mission. “We need to connect and learn what’s going on globally,” says Dr Patrick Hartley, leader of the Hydrogen Industry Mission. According to Hartley, the project will “connect our … Continue reading CSIRO’s renewable hydrogen initiative

“The Norway of Australia”: what does good electric vehicle policy look like?

The NSW Government has just joined the pack of state governments announcing electric vehicle subsidies, with a $500 million policy to incentivise purchase of electric vehicles, and improve EV infrastructure. So, what’s involved in NSW’s new policy, how does it compare to other states, and what’s slowing electric vehicle uptake in Australia? NSW’s new policy … Continue reading “The Norway of Australia”: what does good electric vehicle policy look like?

Lithium: Powering the Green Revolution

A worldwide clamour for better battery power has caused a “white gold” rush on lithium. Shortages loom, fuelling a race to find new sources of this rare element. As the climate warms, sea levels rise and droughts, heatwaves and bushfires multiply, the need to usher in the green-energy future is increasingly urgent. But that doesn’t mean … Continue reading Lithium: Powering the Green Revolution

Cosmos Briefing: Lithium

As the demand for renewable-energy technologies skyrockets, we need to think about how to source their constituent materials without further damaging the world we’re trying to save, according to yesterday’s Cosmos Briefing. Rick Valenta, from the Sustainable Minerals Institute at the University of Queensland, and Mahdokht Shaibani, a research fellow at Melbourne’s Monash University, discussed … Continue reading Cosmos Briefing: Lithium

Five things you didn’t know about lithium

Our next regular Cosmos Briefing asks the question: Is Lithium the Answer? We are drilling down on lithium and the future of renewable energy with energy and mining experts. Ahead of the webinar on 21 January, we take a look at five things you didn’t know about lithium. Lithium has cosmic origins Lithium was the … Continue reading Five things you didn’t know about lithium
