Australia won’t have ‘green steel’ to itself. Africa is poised to become a global hub

By Charlie Huang, RMIT University Australia is at the forefront of efforts to turn steelmaking green. Earlier this year Australian iron ore producers Rio Tinto teamed up with Australian steelmaker BlueScope to develop “near-zero emission-intensity” pathways for making steel from Pilbara iron ore. Renewable electricity and hydrogen would replace coking coal. Iron ore miner Fortescue…

Solar above, batteries below: here’s how warehouses and shopping centres could produce 25% of Australia’s power

By Bruce Mountain, Victoria University Imagine if Australian cities became major producers of clean energy, rather than relying on far-flung solar and wind farms. Far fetched? Hardly. Our cities and towns are full of warehouses, commercial areas, shopping centres and factories. These types of buildings have one very important underutilised resource – large expanses of…

Australian team to develop health monitoring device for space passengers

The Australian National University, Axiom Space and Aqacia are partnering through a project supported by the iLAuNCH Trailblazer to develop a wearable space health device. According to a statement from iLAuNCH on Tuesday, the device “will sense, transmit, and real-time assess health data in remote areas including sub-orbital flights” and help “enable real-time simulation, diagnosis,…

Small modular reactors have promise. But we found they’re unlikely to help Australia hit net zero by 2050

By Ian Lowe, Griffith University and Kylie Walker, Australian National University Australia’s clean energy transition is already underway, driven by solar, wind, batteries and new transmission lines. But what about nuclear? Opposition leader Peter Dutton last month committed to building nuclear reactors on the site of retired coal plants – triggering intense debate over whether…

Sodium-ion batteries are set to spark a renewable energy revolution – and Australia must be ready

By Peter Newman, Curtin University The extent to which renewables should dominate Australia’s energy grids is a major issue in science and politics. Solar and wind are clearly now the cheapest form of electricity. But limits to these technologies can undermine the case for a renewables-only electricity mix. The challenges posed by solar and wind…

Australia needs large-scale energy production – here are 3 reasons why offshore wind is a good fit

By Ty Christopher, University of Wollongong and Michelle Voyer, University of Wollongong On the weekend, an area 20km off the Illawarra coast south of Sydney became Australia’s fourth offshore wind energy zone. It’s the most controversial zone to date, with consultation attracting a record 14,211 submissions – of which 65% were opposed. The zone’s declaration…

Future Made in Australia will boost sustainable growth and create jobs as far as it goes, but it doesn’t go far enough

By Sanjoy Paul, University of Technology Sydney and Priyabrata Chowdhury, RMIT University The shift towards net zero emissions and greater international competition have created new opportunities for clean energy industries – poised to shape the global economy in the coming decades. To harness these opportunities, the government has developed a long-term strategic initiative called the…
