A report which looks at the technical and economic conditions required for the integration of hydrogen into gas network infrastructures has been released by gas infrastructure operators in France.
The report confirms the ability to integrate a significant volume of hydrogen into the gas mix by 2050 with limited infrastructure adoption costs, meaning gas infrastructures will soon be able to accommodate decarbonised and renewable hydrogen.
In short term, a volume of 6% hydrogen is feasible as a blend in most networks. It requires very few adaptions and is compatible with most of the installations of today’s gas consumers.
A pre-identification exercise aimed at injection project promotors will be launched in order to locate areas favourable to the injection of hydrogen as a blend.
These areas will then be progressively expanded in line with results of research and development activities, replacement of specific equipment and the deployment of solutions guaranteeing the quality of the gas to consumers.
To facilitate the deployment of projects, gas operators recommend setting a target of 10% blended hydrogen as a sector-wide target by 2030, then 20% beyond. By 2050, significant volumes can be injected with controlled costs in terms of infrastructure adaptation.
The report is part of the hydrogen deployment plan which was launched for France back in 2018 by the Ministry of Ecological Transition and Solidarity.
