Australia’s richest man recently took on the world’s richest man over the shape of our green future. But it’s not either batteries or green hydrogen – we need both.
The key to reducing green hydrogen costs in the future lies mainly in technological improvements.
A new energy deal between Canada and Germany could revitalize the Port of Churchill in Manitoba by increasing ammonia export traffic.
The US is a latecomer to offshore wind development, but President Biden has set big goals for expanding it. The Gulf of Mexico has good conditions and a large offshore energy industry.
To develop a hydrogen economy at the scale of Aotearoa’s climate ambitions would require about a quarter of the country’s current energy use and swallow enormous amounts of water.
Our new approach lets us separate, store and transport tricky gases like hydrogen as a solid - and for a fraction of the energy.
This week, Austalia began a climate pivot on its relationship with the region. Fossil fuels are out and exporting green energy and green manufacturing techniques are in.
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
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.
