This integrated infrastructure model transforms storage from isolated assets into dynamic components of a continent-wide hydrogen energy system.

MARKET CHALLENGES

Material Compatibility and Hydrogen Embrittlement in Existing Storage Infrastructure

The risk of hydrogen embrittlement, which involves the degradation of steel and other metals when exposed to high-pressure hydrogen and compromises the integrity of repurposed natural gas infrastructure, is a challenge for the European hydrogen energy storage market. According to sources, Hydrogen exposure can cause materials used in gas pipelines to degrade. This degradation includes the formation of micro-cracks in decommissioned pipelines under specific pressure conditions, as well as a significant loss of tensile strength in standard pipeline steel under pure hydrogen conditions. Because of this, pipeline operators may need to invest in costly solutions, such as internal lining or full material replacement, to accommodate hydrogen transport. These findings complicate the EU’s assumption that a portion of existing gas infrastructure can be reused for hydrogen, as stated in the Hydrogen Backbone roadmap. Operators confront liability risks and insurance uncertainty in the absence of standardized material certification protocols and in-line monitoring systems.

Absence of Unified Market Design for Valuing Long-Duration Storage Services

A lack of a harmonized electricity market framework that financially recognizes the unique grid reliability benefits of hydrogen energy storage during prolonged renewable droughts, thereby obstructing the expansion of the European hydrogen energy storage market. Current markets reward only short-term services like frequency regulation—favoring batteries over hydrogen. Investor confidence will not improve, and energy storage projects will continue to be fragile in Europe until providers can secure a predictable income stream for grid resilience, rather than relying on profits from energy arbitrage.
