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.
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.
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.
While it’s impossible to stop all extraction of fossil fuels now, renewable sources are already generating 25% of global electricity demand now and their contribution continues to grow.
