FYLLINN Innovative hydrogen storage for liquid hydrogen in conformable tanks

Purpose and goal:

The FYLLINN project pre-study has developed a technology platform for future cryogenic hydrogen storage tanks. The project identified suitable materials and welding techniques, developed efficient fixturing and assembly methods, and created a mock-up of a conformable tank. The results demonstrated success in material selection, joint strength, and structural design, establishing a strong foundation for further development and practical application of innovative hydrogen storage solutions.

Expected results and effects:

The FYLLINN project pre-study has developed a technology platform for future cryogenic hydrogen storage tanks. The project identified suitable materials and efficient welding techniques, developed fixturing and assembly methods, and created a mock-up of a conformable tank. The results show that material selection, joint strength, and structural design have been verified, establishing a strong foundation for further development and practical application of innovative hydrogen storage solutions.

Approach and implementation:

The preliminary study has been conducted using an agile approach with a WBS (Work Break-Down) where each part has been calculated, designed, and manufactured separately. The parts have then been progressively integrated using different production methods, with both functionality and capability continuously analyzed. We believe this approach has been very successful, with consistently good progress and, in some areas, far ahead of schedule.

Our conclusion is that a segmented working method is preferable when developing new technology that has no previous equivalent.
