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.
Prominent academics, including a former IPCC chair, round on governments worldwide for using the concept of net zero emissions to ‘greenwash’ their lack of commitment to solving global warming.
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.
