Feasibility study on Component Test Bed for Cryogenic Renewable Fuels (CTB-cryo)

Sammanfattning

The demand for a sustainable and high-performance energy solution increases, and liquid hydrogen (LH2) emerges as a promising candidate. Meanwhile, there is limited expertise and knowledge regarding LH2 for the aviation industry. The purpose of this feasibility study is to provide dimensions of a realistic and comprehensive Centaur Test Bed (CTB) design for cryogenic fuel components, focusing on LH2 . The methodology of the study was divided into two parts. First was a literature study which included a review of all European and Swedish facilities and companies that work with cryogenic testing and supplying, along with a review of different test sections for LH2 in cryogenic testing and an overview of the supply of LH2 . The second part included a sizing analysis of selected components for the test bed, as well as a cost analysis of the components and three scenarios of supplying LH2 to the test bed’s facility: (1) LH2 is supplied and stored in a tank; (2) H2 is supplied as compressed gas and liquefied on site in tanks with cryocoolers; and (3) H2 is produced and liquefied on site. A sensitivity analysis was conducted on the three scenarios (30%, 50% and 100%) to assess how sensitive the costs are to changes in input levels. For scenarios 2 and 3, a sensitivity analysis was made on the testing rounds per week to see how sensitive the CAPEX were for 1 to 4 test rounds per week. The result shows that the third scenario of “H2 is produced and liquefied on site” is the most cost-effective option for the small-scale test facility with 26,07 [EUR/kg/year]. The sensitivity analysis on the testing rounds for scenario 2 and 3 shows no significant changes in the cost.
