H2 Readiness

Within the H2 Readiness project, a roadmap for a dedicated hydrogen grid and a H2 blending strategy for Austria will be developed.

The roadmap and the blending strategy will be based on a sound as-is analysis of the hydrogen compatibility of the gas grid and the storage facilities, and will be carried out according to technical and economic aspects. The implementation of this project will be done in 3 phases:

Phase 1: Survey of the H2 readiness of the network and the storage facilities.

In this phase, components installed in the gas network will be surveyed and evaluated for their hydrogen compatibility. In general, a share of 10%, 20% and 100% hydrogen will be evaluated. Furthermore, a cost estimate for possible necessary retrofits of the networks and the storage facilities will be carried out.

Phase 2: Roadmap for a H2-grid

The goal of the roadmap for a dedicated hydrogen network is to design the development of a hydrogen network. It should be able to meet the future hydrogen demands of the end customers and transports to and from the storage facilities.

A concept for a hydrogen network has already been elaborated. The existing gas grid was divided into 2 grids, a dedicated H2 grid and a CH4 grid. The dedicated H2 grid is able to serve the future demands of the end customers under all possible feed-in scenarios. The remaining CH4 grid can supply end customers with a total capacity of 22 GW.

The concept was presented at the AGID on November 8, 2021.

Survey of future hydrogen sources and sinks 

In a second step, a more detailed analysis is carried out based on a bottom-up survey of future hydrogen sources and sinks. In combination with the long-term and integrated planning, detailed questionnaires for the survey of future hydrogen consumption and hydrogen supply were developed and made available to the distribution system operators. This survey also serves as a basis for the long-term and integrated planning of the gas distribution network infrastructure in Austria.

By providing information on demand and feed-in capacities, future hydrogen demand and hydrogen supply can be taken into account in planning in time, thus enabling an efficient and targeted development of a dedicated hydrogen network. Based on the data provided, the necessary network development measures for the development of a hydrogen infrastructure are then determined while maintaining the system stability and supply security of the current gas network infrastructure.

In order to get an overview of current hydrogen pipeline projects as well as possible existing pipelines with free capacities available for future hydrogen transport (gas, oil, etc.), a questionnaire has been prepared.

We therefore ask you to fill in the questionnaires as conscientiously as possible and to get in contact with your distribution system operator by April 29, 2022 or to get in contact with us directly and thus lay the foundation for the renewable future of the gas infrastructure.

Phase 3: Development of a blending strategy

The development of the blending strategy is to determine the feasibility of blending hydrogen into the CH4 grid. The goal is to develop optimal injection points and electrolysis sites.
