It's unclear exactly what mix of technologies will drive the zero-emission vehicles of the future. But in terms of 'well-to-wheel' efficiency, electric batteries outperform hydrogen.

A year ago, the world's largest lithium-ion battery began dispatching power to South Australia's grid. It has been a remarkable success but there are some concerns that have so far escaped scrutiny
The battery technology and cooling systems needed for electric aircraft to lift people and cargo are getting closer to reality, but they're still very different from electric cars and trucks.
Federal Labor has promised to give rebates of up to $2,000 to 100,000 households to install batteries to store power from solar panels. Is this good energy policy, or just middle-class welfare?
Is it too much to dream of batteries that are part of the structure of an item, helping to shape the form of a smartphone, car or building while also powering its functions?
Paper-based devices with foldable, biodegradable batteries provide a new way to reduce electronic waste. But how would these new gadgets work?
We take salt water for granted, and often overlook how important it is for our own lives and in sustaining a healthy planet.
Taking millions of gallons of water permanently out of the Colorado River amid a prolonged drought would surely start an interstate fight.
The hydrogen economy has been touted for decades as a way to navigate the clean energy transition. Now a new CSIRO roadmap sets out how hydrogen power can become a major energy player.
Parents, carers and doctors need to be aware of button batteries in toys and household devices and ensure they can't be ingested.
Electric cars and smartphones have created growing demand – and volatile prices – for once obscure metals.
Saving power to use later lets consumers, businesses and utilities generate energy when it's cheap and deliver it when they need it most. There's not much of it today, but the industry is growing fast.
A new rechargeable 'proton battery' - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
'Virtual power plants' offer extra power to the grid by tweaking the operation of batteries and appliances right across the network. But even this might be too blunt a tool for our future energy needs.
Our energy system puts consumers more or less at the mercy of business and regulators. What if the future of energy meant putting the power back in the hands of households?
Demand for energy storage is increasing – both in Australia and around the world. But issues with the production of lithium-ion batteries mean the search is on for alternatives.
Boron is the hidden ingredient in a lot of our technology. Get to know this plucky little element.
The UK is about to miss an opportunity if it tries to take on the giants of the lithium-ion battery industry.
High energy, high power and endless life cycles: not all batteries are created equal.
We need to think about the raw materials of batteries -- where they come from and their environmental cost.
