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.
Britain's electricity supply is getting greener but the burning question remains over how to decarbonise heating.
There is a golden opportunity for South Africa to transition from being a key contributor to global warming to becoming a key contributor to global emissions reductions.
Coal and gas have been proposed as a way to make 'clean' hydrogen. But that road is full of challenges.
Just 1kg of hydrogen can power a split-cycle air conditioner for 14.5 hours. The possibilities are endless - and now we have a plan to get there.
Australia can become a renewable energy exporting superpower, but timidity won't get us there.
Things get weird at the quantum level and now we know they can happen really fast when a particle pushes through an almost insurmountable barrier.
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.
Hydrogen is the first element in the periodic table and essential for life on Earth. It may also be key to shifting away from fossil fuels toward clean sources of energy, but challenges remain.
A new pathway for the global energy transition shows how the world can meet the Paris Agreement's 1.5C warming goal without relying on carbon capture and storage, by creating a renewable gas industry.
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 latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.
The hydrogen economy has been touted for decades as a way to navigate the clean energy transition. Now a new CSIRO roadmap sets out how hydrogen power can become a major energy player.
Even a small cloud can weigh as much as four tonnes – but gravity, chemistry and temperature keep them floating in the sky.
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.
Feb. 28 marks the 75th anniversary of Operation Gunnerside. A stealthy group of skiing commandos took out a crucial Nazi facility and stopped Hitler from getting the atomic bomb.
It's like one great big distillery up there.
After months of running in test-mode, the Australian Square Kilometre Array Pathfinder telescope is now gathering data at an incredible rate to give us a new look at how our universe works.
Fusion development takes time. It cannot be developed in miniature and then be simply scaled up. But we must work now, to make it possible to meet humanity's need for abundant, clean energy.
A new telescope aims to figure out what became of the universe's original atoms once the first stars began to shine.
