R&D is concentrated on low-pressure, materials-based technologies and lower-cost, high pressure tank technologies for hydrogen storage systems to meet performance targets. Three overarching performance targets for onboard hydrogen storage systems are: gravimetric capacity; volumetric capacity; and system cost. kWh/kg (5.5

In the near-term (2012-2017), DOE sees an opportunity to more than double the battery pack energy density from 100 Wh/kg to 250 Wh/kg through the use of new high-capacity cathode materials, higher voltage electrolytes, and the use of high capacity silicon or tin- based intermetallic alloys to replace graphite anodes. —Blueprint.
