Graphene-Nanotube Combo Exceeds Benchmarks for Hydrogen Storage in Fuel Cells

With lithium-ion (Li-ion) batteries becoming the de-facto energy source for next-generation vehicles, some of us remember that there was a time when fuel cells were thought to be the most viable solution for powering vehicles after the internal combustion engine.

Of course, this is only a perception based on how companies like Tesla have made the Li-ion battery seem to be the best option. However, the US Department of Energy (DoE) has set benchmarks for what storage materials will need to deliver in order to compete for a place in post-fossil fuel vehicles.

Now researchers at Rice University have developed a nanomaterial for fuel cells that consists of layers of graphene separated by nanotube pillars of boron nitride. The material might tick all the boxes established by the DoE for next-generation vehicles.
