Descripción del proyecto ENERGY TRANSITION IS PART OF THE ECOLOGICAL TRANSITION AND HYDROGEN TECHNOLOGY IS CONSIDERED A KEY ENABLING TECHNOLOGY TO LEAD SOCIETY TOWARDS A DECARBONIZED ECONOMY, THROUGH THE PROMOTION OF THE HYDROGEN CHAIN VALUE AND ITS INTEGRATION IN THE DIFFERENT PRODUCTIVE PROCESSES.ONE OF THE KEY FACTORS FOR HYDROGEN TO MAKE A SIGNIFICANT CONTRIBUTION TO THE ENERGY TRANSITION IS THE NEED TO BE STORED AND DISTRIBUTED. THE SELECTION OF MATERIALS TO PRODUCE TANKS, TUBES OR VALVES TO STORAGE AND TRANSPORT HYDROGEN RELAYS IN MATERIALS PERMEABILITY TO HYDROGEN AND THEIR SUSCEPTIBILITY TO EMBRITTLEMENT. THE H PENETRATES, FORMS PORES AND GENERATES CRACKS THAT EMBRITTLES THE MATERIAL WITH THE RESULT OF FRACTURE. RECENTLY, HIGH ENTROPY ALLOYS (HEA) ARE RECEIVING INCREASING ATTENTION AS A NEW CLASS OF POTENTIAL MATERIALS TO WITHSTAND CONTACT WITH HYDROGEN.NEXTHEA4H2 PROPOSES THE STUDY OF THE PERFORMANCE OF TWO HEA IN CONTACT WITH HYDROGEN. FOR THIS PURPOSE, ASTM AND ISO STANDARDS DEVELOPED TO MEASURE PERMEATION TO HYDROGEN BY ELECTROCHEMICAL METHODS WILL BE APPLIED. TWO STEELS CURRENTLY USED FOR APPLICATIONS IN CONTACT WITH HYDROGEN WILL BE ALSO TESTED AS REFERENCE MATERIALS. UNDER THESE STANDARDS THERE ARE A LARGE NUMBER OF EXPERIMENTAL CONDITIONS THAT CAN AFFECT THE RESULTS OF THE TEST. ON ONE HAND EXPERIMENTAL CONDITIONS AS TEMPERATURE OR CHEMICAL ELECTROLYTE CHARACTERISTICS. ON THE OTHER HAND, MATERIAL VARIABLES SUCH AS FINISHING QUALITY OF THE CHARGING AND DISCHARGING SURFACES, SUPERFICIAL RESIDUAL STRESSES OR DENSITY OF CRYSTALLOGRAPHIC DEFECTS IN THE MATERIAL. THEREFORE, AN EXHAUSTIVE ANALYSIS OF THE EXPERIMENT ITSELF MUST BE ACCOMPLISHED TO UNDERSTAND WHICH CONDITIONS OR VARIABLES GENERATE NOISE AND INCREASE THE VARIANCE IN THE RESULTS OF THE TESTS, I.E. DIFFUSION COEFFICIENT AND SOLUBILITY PARAMETERS.TO PRODUCE RELIABLE CHARACTERIZATION OF THE MATERIALS IT IS PROPOSED TO DEFINE AND VALIDATE AN ADVANCED DESIGN OF EXPERIMENTS BASED ON THE USE OF COVARIANCE INFORMATION. THIS PROCESS ALLOWS GATHERING INFORMATION TO BE ANALYZED BY MEANS OF DATA MULTIVARIATE ANALYSIS, ENABLING TO FIND SIGNIFICANT RELATIONS BETWEEN EXPERIMENTAL CONDITIONS AND THE MEASURED VARIABILITY OF THE RESULTS. WITH THIS FINITE INFORMATION, MATHEMATICAL MODELS BASED ON CLASSICAL AND ADVANCED MACHINE LEARNING TECHNIQUES CAN BE GENERATED. THE MODELS WILL ALLOW TO EXPAND THE INFORMATION TO THE ENTIRE SPACE OF PROPOSED OPTIONS, ALLOWING TO OBTAIN INFORMATION FOR LARGER NUMBER OF CASES AND POSSIBLE SIGNIFICANT CASES WITHIN THE SPACE WILL BE TESTED TO VALIDATE THE PROCESS.ONCE THE EXPERIMENTAL PROCEDURE IS OPTIMIZED, THE RESULTS OBTAINED FOR THE TWO HEAS AND THE REFERENCE STEELS WILL BE DEEPLY DISCUSSED. PARTICULAR ATTENTION WILL BE PAID TO THE EFFECT OF THE MATERIAL SURFACE FEATURES ON THE DIFFUSION COEFFICIENT AND ITS VARIABILITY AND THE EFFECT ON TRAPPING-DETRAPPING MECHANISMS IN HYDROGEN SOLUBILITY. THIS ANALYSIS WILL ENABLE TO DESIGN THE OPTIMAL SURFACE FINISHING FOR FUTURE COATINGS INTENDED AS HYDROGEN PERMEATION BARRIERS.THE WORK TEAM COMPRISES EXPERTS WITH STRONG EXPERIENCE/SKILLS IN PHYSICAL METALLURGY, MATERIALS CHARACTERIZATION AND ADVANCED TECHNIQUES OF DATA ANALYSIS. ALONG THE PROJECT, WE INTEND TO CONTRAST OUR RESULTS WITH END-USERS THROUGH THE BASQUE CLUSTER OF ENERGY (ASSOCIATION OF 180 COMPANIES WHICH ACTIVITY IS RELATED SOMEHOW TO ENERGY). THIS BRINGS THE NECESSARY RANGE OF TECHNICAL AND END-USER KNOWLEDGE REQUIRED TO DELIVER OUR AMBITIOUS RESEARCH AIM.
