We\u2019ve written several times about structural batteries in this blog, from Dr. Emil Greenhalgh\u2019s early research at Imperial College to more recent efforts along the same line.<\/a>\u00a0 Interestingly, the basic idea remains very much the same over a decade.\u00a0 Energy storage would take place in a monocoque-type structure that could use carbon fiber, fiberglass, and even graphene as\u00a0 a structural material, while acting as a battery.\u00a0 Now some of this thinking is being applied to hydrogen storage in wings.<\/p>\n

APUS, an aircraft design, structure and certification operation in Strausberg, Germany<\/a>, offering a full range of services including flight training.\u00a0 They recently announced two new craft, both featuring hydrogen fuel systems contained in a novel \u201c\u2026 \u00a0patented structurally integrated hydrogen storage system, known as TubeStruct\u2122.\u201d\u00a0 In the shadow drawings of the airplanes, the tubes appear as though they could double as redundant wing spars.<\/p>\n

APUS i-2\u00a0 will be comparable in dimensions and performance with more conventional light twins, but will be a zero-emission vehicle<\/p><\/div>\n

The i-2, a four-seat Normal-Category (CS-23) aircraft; and \u201cThe APUS i-6 is a technology demonstration platform with 2.8t MTOM (Mean Take-Off Mass).\u201d\u00a0 Both will be propelled by Siemens SP-70 motors (or whatever the Rolls-Royce equivalent will be)* \u2013 two on the -2 and \u201cup to seven\u201d on the I-6.<\/p>\n
