THE GOAL OF THE PROPOSED PROJECT IS TO DESIGN, MANUFACTURE, AND TEST A COMPOSITE LIQUID HYDROGEN (LH2) TANK WITH A CAPACITY OF 20 KG. THE TANK WILL BE SCALABLE TO LARGER SIZES OF 60-120 KG FOR HEAVY TRUCK APPLICATIONS AND 200-1000 KG FOR AIRCRAFT APPLICATIONS, AND THIS SCALED DESIGN WILL BE ABLE TO MEET DOE PERFORMANCE TARGETS WHEN PRODUCED IN VOLUME. THE TARGETED TANK SPECIFICATIONS FOR THE PROTOTYPE DESIGN AND SCALED DESIGN ARE COMPARED TO THE DOE TARGETS IN TABLE 1. IN BUDGET PERIOD 1, SPANNING MONTHS 1-12 OF THE PROJECT, THE DESIGN SPECIFICATIONS, AND A CONCEPTUAL DESIGN FOR THE LH2 TANK WILL BE DEVELOPED. MATERIALS FOR THE COMPOSITE, RESIN, AND ALUMINUM LINER AND ASSOCIATED MANUFACTURING PROCESSES WILL BE EVALUATED. IN BUDGET PERIOD 2, SPANNING MONTHS 13-24, THE MATERIALS FOR THE COMPOSITE, RESIN AND ALUMINUM LINER WILL BE SELECTED ALONG WITH THE ASSOCIATED MANUFACTURING PROCESS. A DETAILED TANK DESIGN WILL BE DEVELOPED, INCLUDING CRYOVESSEL, VACUUM VESSEL, SUSPENSION, AND MOUNTING. ALL THE NECESSARY PORTS AND PIPING CONNECTIONS, FUELING, DEFUELING AND SAFETY MANIFOLDS WILL ALSO BE SPECIFIED AND SOURCED. IN BUDGET PERIOD 3, SPANNING MONTHS 25-36, ALL THE COMPONENTS OF THE PROTOTYPE LH2 TANK WILL BE MANUFACTURED. THE TANK WILL BE ASSEMBLED AND WILL BE TESTED WITH ALL NECESSARY PORTS AND PIPING CONNECTIONS UNDER FUELING, DEFUELING, AND DORMANCY CONDITIONS.
