The contribution of CNH2 will be key in the development of Activity-2. The research developed by the CNH2 will allow us to advance our knowledge of the interaction of Hydrogen with the selected pilot reservoir. As well as with natural gas still present, in order to achieve the objective of developing the technological base for the storage of green Hydrogen in fields depleted of natural gas.

The CNH2 will focus its research on investigating the interaction between gases (H2, CH4, CO2) and with the reservoir and seal rocks in the reservoir conditions (Pressure, Temperature and brine content). It will also study, among others, methanation reactions due to microbial metabolism.

On the other hand, within Activity-4, CNH2 will carry out the evaluation of the technical requirements that the equipment of surface facilities must meet for use with hydrogen. This research will result in obtaining a selection of critical equipment based on the service it provides, as well as the material that composes it, and then carry out a battery of tests on these to validate their suitability for the work they must perform and that there is no risk.

It will also carry out the compatibility study of materials used in the exploitation of geological storages with hydrogen, evaluating the susceptibility to hydrogen fragility of the constituent materials of the systems located on the surface of the geological storages under high pressure hydrogen.

Within Activity-6, CNH2 will contribute to the technical-economic analysis of the different technological options to achieve efficient sizing of renewable generation and seasonal storage of green hydrogen. To do this, it will analyze other industrial, agricultural and transportation sectors, investigating the synergies that allow maximizing the generation potential of renewable energy.
