Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Fuel cells could eventually power material-handling vehicles such as forklift trucks in the logistics sector. An EU-funded project is working on proving the market readiness of energy storage components.
