Single-Aisle Aircraft LH2 Storage System

GTLrsquo;s breakthrough ultra-lightweight composite dewar-tank technology is game changing by providing hydrogen weight fractions in excess of 59% for small tanks, with over 70% achievable with medium scale LH2 tanks, including vacuum insulation. This capability addresses a critical need in the conversion of single-aisle aircraft from Jet-A to liquid hydrogen to eliminate carbon emissions. With GTLrsquo;s composite LH2 dewar-tanks, hydrogen powered aircraft can achieve better performance than Jet-A aircraft and operate with less cost per passenger mile.GTL is commercially developing and validating the composite LH2 dewar-tank. This commercial funded effort includes the fabrication and ground testing of multiple composite LH2 dewar-tanks that will culminate in prototype flight testing on a helicopter.In this SBIR, GTL will examine the integration of composite LH2 dewar-tanks into single-aisle aircraft. This includes showing how the composite LH2 dewar-tank technology can meet relevant performance, operational, and safety requirements of single-aisle aircraft. The effort will also create a technology roadmap of the development, verification and validation steps needed to mature the technology from its current state to the point where it can be adopted by aircraft developers.
