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.
The sun is setting on oil and gas. Creating green income trusts could give private investors incentives to massively scale up investments in new low-carbon energy technologies — and help the province of Alberta.
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.
Artist Albert Robida imagined in 1882 how air travel might look in future.
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%.
NASA has launched all of its space shuttle missions using hydrogen as fuel.
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.
The world’s first commercial hydrogen-fuelled train in Germany.
Fuel cells are being touted as an alternative to costly electrification – but no one knows if they'll really be cheaper.
FaHyence hydrogene filling station in action.
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.
The Loy Yang station will be the site of a new hydrogen fuel project.

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.
The proton battery, connected to a voltmeter.
A new rechargeable 'proton battery' - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
What a gas: one of Moreland’s new hydrogen-powered garbage trucks.
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.
Hydrogen fueling stations like this could become more common if materials scientists and other researchers keep pushing for new breakthroughs.

There is a boom in renewable energy sources coming online worldwide, but the predominant types – solar and wind – are problematic due to their variable nature. For most regions of the world, the sun cannot…
Time to put some heat into the hydrogen industry.

The inhabitants of a frequently cold and windy country like the UK need to heat their homes, even in what is loosely termed “summer”. This is achieved mostly by natural gas-fed boilers – but this dependence…
Back on the road: a hydrogen-fuelled car at a US trade show.
We hear a lot about wind, solar and nuclear energy in the fight to reduce carbon emissions, but it seems we’ve forgotten about hydrogen fuel. Hydrogen — made by splitting water — was considered energy-intensive…
