There are two approaches to producing low-emission hydrogen, and public acceptance (or rejection) of each method will be important for hydrogen and its place in the energy transition.
A new study estimates a reduction in emissions of only 35-45% of pre-COVID levels by 2050. Lighter vehicles and faster uptake of electric vehicles can dramatically improve progress towards net zero.
Australia’s emerging green hydrogen industry requires a secure supply of high-quality water. Competing demands for this scarce resource mean careful planning is needed to meet all water users’ needs.
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.
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.
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.
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.
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.
