Researchers Claim New Material Can Store Hydrogen At Lower Pressures
The new metal-organic framework (MOF) has nanoscopic pores that can retain the gas.
Fuel cells bear a promise of clean transportation that is very attractive. It would just require hydrogen – the most abundant element in the universe – to combine with oxygen, generate electricity, and move cars around. But they face so many issues they are still willing to prove themselves as a viable option. Perhaps the major problem it has is how to store hydrogen more securely. Fans of the solution will be happy to hear Northwestern University researchers may have solved it.
They had to tackle both the volumetric (size) and gravimetric (mass) deliverable capacities of hydrogen and also of methane, which can be converted to hydrogen. Their solution for that was a new metal-organic framework (MOF) with a highly porous surface that they decided to call NU-1501.
The way these researchers found to explain what it does was calling it a “programmable sponge.” In contact with NU-1501, hydrogen forms a layer over it, a process that is called adsorption.
The new MOF has almost incredible properties. One gram of it – which would have a similar volume to six M&Ms – has a surface that is equivalent to 7,310 m², or the same area of 1.3 football field.
