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.

AGL has announced plans to use coal to make hydrogen fuel at its Loy Yang A station in Victoria's Latrobe Valley. Wait, isn't coal made of carbon, not hydrogen? Yes, but here's how the process works.
A new rechargeable 'proton battery' - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
A local council goes for hydrogen. A state government goes for lithium and mirrors. They are taking punts on technology. What are the risks?
Volvo might be the first car company to go all-electric, but it's far from the market leader and petrol will continue to be relied upon.
Modifying chemicals' molecular properties can make 'splitting' hydrogen from water more efficient.
New technique captures 78% carbon using molten tin.
The VW emissions scandal is an opportunity to forge ahead with fuel cell technology for cars.
There is a boom in renewable energy sources coming online worldwide, but the predominant types – solar and wind – are problematic due to their variable nature. For most regions of the world, the sun cannot…
The inhabitants of a frequently cold and windy country like the UK need to heat their homes, even in what is loosely termed “summer”. This is achieved mostly by natural gas-fed boilers – but this dependence…
We hear a lot about wind, solar and nuclear energy in the fight to reduce carbon emissions, but it seems we’ve forgotten about hydrogen fuel. Hydrogen — made by splitting water — was considered energy-intensive…
There is increasing talk of electrification of the UK’s railway network. But electrification is an expensive business, requiring much new hardware including masts, wiring, substations and so on. Such an…
Should ecosystems have legally enforceable rights? It might sound like a ridiculous idea, but a global debate on this is in full swing. The Constitution of Ecuador now recognises rights of nature. Environmental…
