Ultra long-haul flights make it possible to go Sydney to London non-stop. But does the world need them, given they are more polluting and less efficient?
China is committed to becoming carbon neutral before 2060 – and producing green hydrogen is key to the plan.
New research finds Japan has 14 times more solar and offshore wind energy potential than needed to supply all its current electricity demand. It doesn’t need Australia.
Electricity, not what the EU calls ‘renewable gases’, offer the fastest route to decarbonising heating.
New technologies will enable steel production without coal. Australia stands to benefit greatly in the shift to green steel – if we’re ready.

Russian President Vladimir Putin has used his country’s massive energy reserves effectively for political influence. But with war in Ukraine, nations are looking for ways to cut those ties.
Any climate gains from Japan’s shift will be wiped out entirely unless Australia moves to zero-emissions ammonia production.
Labor wants to run the Kurri Kurri gas power station on green hydrogen. But the figures don’t stack up.
There’s a lot of buzz around green hydrogen. But we need to get the groundwork right - and pick the best spots to produce it
China is currently in a better position than the West to assist the Indo-Pacific, due to geography, trade dynamics and its own clean tech sector.

Western democracies need to create a financing program to support the energy transition in the Indo-Pacific — and to achieve both regional security and climate goals.

Universities have long been developing research, talent and technology that, with the right mix of industry and government support, will allow Australia to emerge as a green export and R&D leader.

Battery electric cars are an ideal choice for light-duty and shorter commutes, but for long-haul trucks or buses, hydrogen fuel cells offer higher loads, shorter refuelling times and a longer range.
Australia’s business sector has recognised the profits to be made in the hydrogen transition. Acting quickly, and powering the shift with renewable energy, is key.
The UK government claims hydrogen could meet one-third of the country’s energy demand by 2050.
Green hydrogen has unprecedented support from business and political leaders. But several challenges remain.
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.
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.
Many oil companies are still planning for fossil fuel use to continue well into the future.

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.
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.
Green hydrogen produced using New Zealand’s mostly renewable electricity sounds like a great idea, but a high-tech smart rail and urban tram network is a more obvious and sustainable option.

The government’s latest energy plans are a failure of logic, and will lock in fossil fuel use for decades.
