Iv.0 Hydrogen storage sub-Program overview IntroductIon The Hydrogen Storage sub-program supports research and development (RD) of materials and technologies for compact, lightweight, and inexpensive storage of hydrogen. In Fiscal Year (FY) 2012, the sub-program focused on system engineering for transportation applications while continuing RD efforts in materials-based storage including metal hydrides, chemical hydrogen storage materials, and hydrogen sorbents. Additionally, work was directed at reducing the cost of compressed gas storage systems (i.e., physical storage) as a near-term commercialization pathway. The storage portfolio, including Basic Energy Sciences, currently includes projects involving 22 universities, 11 companies, and 13 federal laboratories and involves work in hydrogen storage materials discovery; materials-based system engineering; advanced high-pressure tank RD; and system performance and costs analyses. Goal The sub-program’s goal is to develop and demonstrate commercially viable hydrogen storage technologies for transportation and early market fuel cell applications including stationary power, backup power, portable power, and material handling equipment. objectIves1 The objective for the storage sub-program regarding light-duty vehicles is to store sufficient hydrogen onboard the vehicle to allow for a driving range of more than 300 miles (500 km), while meeting packaging, cost, safety, and performance requirements to be competitive with current vehicles. Although automakers have made progress in demonstrating some vehicles able to travel more than 300 miles on a single fill using high- pressure tanks, this driving range must be achievable across different vehicle models without compromising space, performance, or cost. By 2017, the sub-program aims to develop and verify onboard automotive hydrogen stor
