RES2H2 - Integration of Renewable Energy Sources with the Hydrogen Vector
Project Duration: 2002/01/01 - 2006/12/31

Project Status:

project in preparation
Project Description

Objectives:

The production of clean hydrogen from renewable energy sources is, without doubt, an important aspect to be taken into account within the real launching of this gas as an "energy vector" of the future, within a society that is ever-increasing its demand for "sustainable development". We must remember that hydrogen is, or is not, a clean energy source, depending on where it comes from. The objective of RES2H2 is to prove that clean production of hydrogen is feasible on an industrial level, and that the problem of temporary energy storage, usually inherent for many renewable energy sources, can likewise be overcome. Therefore, the integration of renewable energy sources with the recently promoted "hydrogen vector" is what is being addressed in this European project.

Challenges:

The objective of this project is the clean production of hydrogen while exploiting a renewable energy source, such as wind power (although solar energy or biomass could also have been considered), to overcome, on one hand, the problem of storing surplus energy (so frequent with renewable energy sources) and, on the other hand, the production of clean hydrogen that effectively meets the demands of an energy vector that is compatible with sustainable development. From a storage point of view, in order to ensure increasing penetration of technologies related to renewable energies in isolated networks or in decentralized generation, these technologies must be integrated in hybrid systems that permit storage of the energy. The most efficient possibility, and that most respecting the environment, is the integration of renewable energies with hydrogen technology, which permits the production, storage and (subsequent) use of the same to generate electricity.

The effort being made is even greater, given that this Project covers four originally independent projects, all at European level, and at two different locations (Greece and Spain). This integrated project joins hydrogen technologies and wind power, with the latter being a renewable energy source with important seasonal variations in power production. Special attention must also be paid to the design of the accompanying water electrolysis unit. Potable water is considered to be another rare commodity, with an increasing energy cost at national and international level. Its co-production will be researched at one of the two locations (Spain). In summary the project will include the design, construction and assessment of two self-sufficient energy systems, in such a way that wind power can be used to generate hydrogen, electricity and water, with the characteristics of hydrogen as an energy vector being used to this end. These types of systems could be implemented in the more or less near future in any region with a high renewable potential (wind power, for example), to produce and commercialize hydrogen and to meet the demand for electricity and water (independent water and renewable energy networks).

Project structure:

A total of fourteen partners are participating in the project. Regarding Greece, an electrolyzer within the 25 to 100 kW range will be connected to a 500 kW wind charger. The hydrogen thus produced ("green" hydrogen) will be stored in a metallic hydride tank (up to 50 Nm3). It will subsequently be compressed in a series of cylinders in a filling station. This compressed hydrogen can potentially be put on the traditional hydrogen market, as a first step to familiarizing the industrial sector with, and gain confidence in, hydrogen as an energy vector.
