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.
The Arecibo radio telescope has collapsed but its amazing discoveries will live on.
Hydrogen is feted as the key to a dynamic green economy. But is it the best choice for decarbonisation in all cases?
Don’t count nuclear energy out – it may be our best hope of reaching net-zero emissions within the time we have left.
It’s encouraging that the federal government recognises its role in industry policy. But its choice to support some technologies is disappointing.
The government’s latest energy plans are a failure of logic, and will lock in fossil fuel use for decades.
The government has unveiled a $1.9 billion package of investments in new and emerging technologies, and reinforced its message that it is time to move on from assisting now commercially-viable renewables.
Tesla founder Elon Musk has described hydrogen-powered cars as “mind-bogglingly stupid”. So is he right?
Hydrogen is hailed as a new clean fuel, but little attention has been paid to the potential environmental challenges presented by the energy shift.
