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.
CO₂ will need to be removed from the atmosphere to avoid catastrophic heating. Can the process be incentivised?
Industrial activity is a major emitter of CO₂.
An innovative method of carbon capture and storage could substantially reduce the emission of small industries while using geothermal energy to heat homes and thus replacing fossil-fuel energies.
Reducing pollution will help stave off climate change but avoiding the worst effects means taking CO2 out of the atmosphere at large scale.

Countries are not on track to meet Paris Agreement goals. A climate researcher argues that a range of technologies that take CO2 out of the air are needed.
Hydrogen from renewable energy such as solar can be produced with zero emissions.
Coal and gas have been proposed as a way to make 'clean' hydrogen. But that road is full of challenges.
A long way to go…
At best, planting trees won't be enough on its own to slow climate change. At worst, it's a dangerous distraction.

A new study lays out what must happen immediately for any hope of limiting global warming to 1.5°C.
A key tool for capturing and storing carbon may have been hiding in plain sight all along.
If only it were that easy.

Trapping carbon dioxide in minerals happens naturally over thousands of years. Can humans speed it up – safely?
Adding industrial chemicals and natural alkaline minerals could slow climate change, but like other geoengineering proposals, it comes with many complex technical and legal challenges.
Drax biomass plant, Yorkshire.
The Drax biomass plant in Yorkshire is the first in the world to pioneer carbon capture and some specialists see it as it has a bright future. But hold the rosy headlines.
Testing new ways to use this technology is underway in Japan.
These technologies could turn into a powerful tool for fighting global warming, and they have the potential to address historical climate injustices.

Alternatives made from common metals like aluminium are available.
The calm before the storm.
Earth is fast approaching the red lines that scientists have urged temperatures cannot cross if we have any hope of avoiding catastrophic climate change. Here are the emergency measures we need.
Opportunities to help drive the energy transition are everywhere - even in Western Australia’s remote salt pans.

Nobel Prizewinning health researcher Peter Doherty reflects on the challenge of delivering a healthy climate for the world. From hydrogen power to wooden skyscrapers, the options are endless, but all require leadership.
Hydrogen fuel is just one opportunity for Australia in a clean-energy future.
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.
Without rapid and dramatic changes, the world will face a higher risk of extreme weather and other effects of climate change.

The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
Painkillers and life jackets are two of the many products that depend on carbon dioxide.
