We need to rapidly reduce global emissions before 2030. Developing hydrogen for low-emissions road transport won’t happen fast enough.
A billion-year-old ‘hydrogen economy’ in the frozen soil of Antarctica provides bacteria with energy, water, and the carbon that makes up their bodies.
The UK prime minister has been setting out ambitions to be a world leader in the coming hydrogen economy.
There are vast quantities of water ice on the moon that represent the potential for extraction and use in rocket fuel. But there are no practical reasons to mine this water.
The UK government claims hydrogen could meet one-third of the country’s energy demand by 2050.
Hydrogen fuel derived from natural gas may be worse for the climate than the fossil fuel even with carbon capture and storage.
Heavy goods vehicles predominantly run on diesel. Here are three options for eliminating their emissions.
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.
If shipping were a country, it would rank between Japan and Germany as the sixth-largest contributor to global carbon dioxide emissions.
Rather than considering the job done, Tasmania should seize opportunities including renewable energy, net-zero industrial exports and forest preservation.
District heating can recycle waste heat and pump it where it’s needed.
Australia’s abundant wind and solar resources mean we’re well placed to produce the hydrogen a green steel industry needs. But there are technical and economic challenges ahead.
There was palpable relief as Biden brought the US back to the table on global climate action, warning “we have to get this done”. Depressingly, Morrison showed little sign of hearing the message.
The world, accustomed to Australia’s shifty climate stance, is unlikely to fall for Morrison’s diversion tactics at Biden’s climate summit this week.
The genius of the Paris climate agreement was getting major oil producing countries to agree to a target, but they still have widely different views of energy’s future.
Hydrogen isn’t very efficient, but it fits many business models.
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.
A recent study shows that the Earth’s water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.
Hydrogen-filled cargo airships could do for the Northern economy what the railways did for Western Canada 125 years ago. It’s time to lift the antiquated ban on hydrogen gas for use in blimps.
The Climate Change Committee has laid out a road map for net zero emissions that the UK government could follow.
