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.
Energy efficiency and electrification should lead the effort to decarbonise society, not hydrogen.
Australia could grab a huge chunk of the world's steel industry, and do it on the east coast, if it gets the technologies right.

The world runs on energy, so finding low-emission alternatives to fossil fuels is crucial. Wind and solar are cheap and abundant but can't do everything. But hydrogen fuel could complete the picture.
Britain's electricity supply is getting greener but the burning question remains over how to decarbonise heating.
Sasol is in an advantageous position. Will it make the right moves?
There is a golden opportunity for South Africa to transition from being a key contributor to global warming to becoming a key contributor to global emissions reductions.
Hydrogen from renewable energy such as solar can be produced with zero emissions.
Coal and gas have been proposed as a way to make 'clean' hydrogen. But that road is full of challenges.
Chief Scientist Alan Finkel says Australia can be a world leader in hydrogen production and export.
Just 1kg of hydrogen can power a split-cycle air conditioner for 14.5 hours. The possibilities are endless - and now we have a plan to get there.
Hydrogen infrastructure in the right places is key to a cleaner, cheaper energy future.
Australia can become a renewable energy exporting superpower, but timidity won't get us there.
Future technologies will exploit today’s advances in our understanding of the quantum world.
Things get weird at the quantum level and now we know they can happen really fast when a particle pushes through an almost insurmountable barrier.
NASA has launched all of its space shuttle missions using hydrogen as fuel.
Ever watched a space shuttle launch? The fuel used to thrust these huge structures away from Earth's gravitational pull is hydrogen. Hydrogen could also be used as a household energy source.
The Periodic Table of the Elements.
Hydrogen is the first element in the periodic table and essential for life on Earth. It may also be key to shifting away from fossil fuels toward clean sources of energy, but challenges remain.
The gas industry of the future could manufacture and deliver renewable fuels, rather than mining and processing natural gas.
A new pathway for the global energy transition shows how the world can meet the Paris Agreement's 1.5C warming goal without relying on carbon capture and storage, by creating a renewable gas industry.
