From diesel to DC
For a long while, it looked as if hydrogen fuel cells would be the technology of choice for emissions-free road transport. However, truck manufacturers and freight forwarders recently turned their attention to battery-electric vehicles. This will require special charging technology and PV looks set to play an important role.
Storing hydrogen in graphene oxide-based nanohybrids
Researchers from the Indian Institute of Technology, Kanpur, and the National Institute of Technology, Srinagar, synthesized and studied nickel nanoparticle dispersed, boron-doped reduced graphene oxide (Ni-B-rGO) samples for hydrogen storage. The results achieved are the best so far for hydrogen storage at the given temperatures and pressures for non-palladium-based systems, they said.
