Climate change: ‘Bath sponge’ breakthrough could boost cleaner cars

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

Like a bath sponge, the product is able to hold and release large quantities of the gas at lower pressure and cost.

Made up of billions of tiny pores, a single gram of the new aluminium-based material has a surface area the size of a football pitch.

The authors say it can store the large volume of gas needed for practical travel without needing expensive tanks. (Text and photo courtesy BBC)
