Scientists at Berkeley Lab do. One DOE-funded project at Lawrence Berkeley National Lab takes Berkeley scientists and pairs them with expertise from the National Institute of Standards and Technology (NIST) and General Motors (GM). The net result? A plan to develop a cost-effective hydrogen storage system for vehicles.
The basic idea is to make a material that can store large volumes of hydrogen at low pressures. This makes using hydrogen more cost-effective (less energy use for high-pressure pumping) and safer (lower pressure makes it safer). So, how does one make a container store more of something without high pressures? Simple, make the storage container’s material a sponge for hydrogen. (That’s the material in the image above.)
