Study on hydrogen quality in dedicated infrastructure and standardisation
Final report
Publication metadata
The study provides a technical analysis as support for further standardization activities on the gas quality in Europe's future hydrogen infrastructure. It synthesizes key literature on the influence of different supply chain elements on hydrogen gas composition and assesses the implications of varying purity levels for end-users. Existing hydrogen quality standards are reviewed, and a wide set ofstakeholder positions, gathered through a survey among key actors of the future hydrogen supply chain, are analyzed. From that, three hydrogen quality specifications (98 mol%, 99.5 mol%, and 99.97 mol%) along with different limits for key contaminants are derived. Finally, the respective costs of purification efforts are assessed for the case, these specifications were applied as a grid standard. The analysis covers different elements across the supply chain, including transport pipelines, underground storage, and different end user groups. The modular cost assessment enables scenario-based evaluations aligned with projected market developments and different grid configurations. The results can support upcoming discussions among key stakeholders on the identification of a common grid specification but also the underlying questions of who should bear the responsibility (and the costs) of ensuring this quality.
