Background

Kyoto Protocol – the reduction of greenhouse emissions – by 2030
European Green Deal strategy
Hydrogen strategy for a climate-neutral Europe
Sustainable and Smart Mobility Strategy (Brussels, 9.12.2020, COM(2020) 789 final) — the main objectives of Hydrogen strategy until 2050

Goal 1: Establishing preliminary assumptions of the mechanisms of gas-layer structure interactions
Goal 2: Development of methodology for surface plasmon resonance (SPR) measurements of sol-gel thin films
Goal 3: Improvement of the current level of sealing of HDPE substrates by organosilane-based sol-gel coatings
Goal 4: Establishment of the hydrogen barrier properties of coatings and its transfer to high pressure conditions
Goal 5: Evaluation of the coatings adaptation to high pressure hydrogen storage requirements
Goal 6: Development of a System for the repeated preparation of layers from the liquid phase on curved large-format surfaces of the tubular type
Goal 7: Development of a Robotized Atomization Spray Coating System based on integrated FPNC ultrasonic head for the wide area coating inside of tubular element
Goal 8: Preparation of the liner with a developed sol-gel coating
Goal 9: Hydrogen permeation tests of the liner with sol-gel sealing coating under real test conditions
Goal 10: (additional one) – Manufacturing of a high pressure vessel using the liner with sol-gel coating layer

Analysis on the possibility of increasing the sealing effect of silica sol-gel coatings — experimental research and mechanism studies.
Production of novel sol-gel coatings limiting the penetration of H₂ through HDPE
Building a tool for activation, atomization, stabilization processes and for discontinuity detection
Building a prototype of system for coating application on the inside of tubular element
Building a prototype of a liner sealed with a sol-gel coating
