Title: Flexible Hybrid separation system for hydrogen recovery from natural gas grid

Brief description of the project

One of the main problems related to the traditional power plants is the great exergetic losses due to the mechanical conversions. To overpass the modern efficiencies of the traditional conversion systems it is necessary to avoid the conversion process based on the combustion of the fuel. Since the fuel cells allow the direct conversion of chemical energy in electricity, they are promising systems that could reach higher efficiency. The importance of the hydrogen is related to this important issue because fuel cells need hydrogen to work. The main hydrogen production system consists on the steam methane reforming and in the case in which it is not possible to convert all the methane, at the end of the process, a mixture of methane and hydrogen is found.

The European project HyGrid arises with the key objective of design, scale-up and demonstration at industrially relevant conditions of a novel membrane based hybrid technologyfor the direct separation of hydrogen from natural gas grids. The focus of the project will be on the hydrogen separation through a combination of membranes, electrochemical separation and temperature swing adsorption to be able to decrease the total cost of hydrogen recovery.  

The results of this project will contribute to the competitiveness of hydrogen separation which is an important issue for chemical and energy fields.

Objectives of the project

•       Define of the reference case and sizing of the HyGrid pre-commercial scale plant.

•       Experimental tests with Pd-Ag and carbon membranes to increase permeability and reduce the costs of the system.

•       Thermogravimetry analysis to analyze the difference of composition with the temperature for a better understanding of temperature swing adsorption system.

•       Modeling of the prototype system in order to implement the economic analysis.
