New research finds Japan has 14 times more solar and offshore wind energy potential than needed to supply all its current electricity demand. It doesn’t need Australia.
We need to rapidly reduce global emissions before 2030. Developing hydrogen for low-emissions road transport won’t happen fast enough.
The US is generating more electricity than ever from wind and solar power – but often it’s not needed at the time it’s produced. Advanced energy storage technologies make that power available 24/7.
Hydrogen could replace fossil fuels, but it’s only as clean as the techniques used to produce it. Almost all production comes from high-carbon sources, but new investments could change that.
Carbon emissions from maritime shipping and port activities are on the rise. But city ports are finding ways to reduce their carbon footprints and reconnect with nearby cities.
If Australia pushes ahead with producing fossil fuels, we may lock in a new high-emissions energy system, or one that’s uncompetitive. Clearly, green hydrogen is the best way forward.
Hydrogen is hailed as a new clean fuel, but little attention has been paid to the potential environmental challenges presented by the energy shift.
Research into income trusts shows that they once helped increase investments in oil and gas. They could do so again — but this time targeted towards low-carbon technologies.
The world runs on energy, so finding low-emission alternatives to fossil fuels is crucial. Wind and solar are cheap and abundant but can’t do everything. But hydrogen fuel could complete the picture.
More than a century since humans learned to fly, we need to revolutionise how we stay up there.
Phosphorene nanoribbons are like tagliatelle, but carry the potential to boost battery capacity by 50%.
Ever watched a space shuttle launch? The fuel used to thrust these huge structures away from Earth’s gravitational pull is hydrogen. Hydrogen could also be used as a household energy source.
Fuel cells are being touted as an alternative to costly electrification – but no one knows if they’ll really be cheaper.
The development of a hydrogen charging station has made it possible to run vehicles without producing greenhouse gases.
It’s unclear exactly what mix of technologies will drive the zero-emission vehicles of the future. But in terms of ‘well-to-wheel’ efficiency, electric batteries outperform hydrogen.
AGL has announced plans to use coal to make hydrogen fuel at its Loy Yang A station in Victoria’s Latrobe Valley. Wait, isn’t coal made of carbon, not hydrogen? Yes, but here’s how the process works.
A new rechargeable ‘proton battery’ - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
A local council goes for hydrogen. A state government goes for lithium and mirrors. They are taking punts on technology. What are the risks?
Volvo might be the first car company to go all-electric, but it’s far from the market leader and petrol will continue to be relied upon.
Modifying chemicals’ molecular properties can make ‘splitting’ hydrogen from water more efficient.
