The project

Learn about the objectives of this project based on innovation

The global objective of the GREENH2PIPES project is research into new materials and manufacturing processes focused on the generation, storage and transport of hydrogen in a competitive manner. For this, it will be done:

Research into new materials and manufacturing processes for the development of innovative components that allow the manufacture of a new generation of PEM electrolyzers, based on national technology, reducing technology costs (CAPEX €1,500/kW) and maintaining efficiency ( 55 kWh/kg) and durability.

The optimization of the injection of green hydrogen generated into the natural gas network that allows optimal integration between the electrical network and the natural gas network, contributing to the decarbonization objectives of the natural gas network.

Research into new catalyst materials for the storage of hydrogen, in the form of organic liquids, that reduce the charge and discharge energy and increase the useful life of the systems to achieve the technical-economic viability of these storage systems.
