Climate Change: ‘Bath Sponge’ Breakthrough Could Boost Cleaner Cars

The title of this post is the same as that of this article on the BBC.

This is the introductory paragraph.

A new material developed, by scientists could give a significant boost to a new generation of hydrogen-powered cars.

The article is a must read and the development could make it a lot easy to store hydrogen in vehicles.

The problem is that hydrogen is extremely light and the article says this about storage.

In normal atmospheric pressure, to carry 1kg of hydrogen which might power your car for over 100km, you’d need a tank capable of holding around 11,000 litres.

That is rather large. This extract from the article describes the solution.

To get around this problem, the gas is stored at high pressure, around 700 bar, so cars can carry 4-5kg of the gas and travel up to 500km before refilling.

That level of pressure is around 300 times greater than in a car’s tyres, and necessitates specially made tanks, all of which add to the cost of the vehicles.

Now researchers believe they have developed an alternative method that would allow the storage of high volumes of hydrogen under much lower pressure.

The team have designed a highly porous new material, described as a metal-organic framework.

As ITM Power’s hydrogen filling stations can provide hydrogen at up to 350-700 bar, I’m sure that there could be a useful coming together, that will make hydrogen-powered vehicles more common.

Could for instance, the new material mean, that hydrogen becomes the fuel of choice for heavy trucks and railway locomotives?
