H2Al Recycling

Prototype for producing hydrogen by means of clean water, ammonia and recycled aluminium, H2Al Recycling

Start 2012 – Finish 2016

Description:

Within this project it has been designed and created a pilot plant to obtain hydrogen from the decomposition of clean water, using aluminium, with the aim of optimizing its efficiency to power a fuel cell.

Aims:

The aim of the project is to produce hydrogen in a safe way, for its possible use as an environmentally friendly energy source. In order to achieve it, the following scientific-technical aims have been set:

  • To study the current situation of technologies about the production of hydrogen.
  • To plan and carry out laboratory tests in order to study the critical parameters of the reaction.
  • To obtain the optimal experimental settings to export it to a pilot plant for the production of hydrogen.
  • To assess the results achieved during the tests carried out with the plant.
  • To monitor the impact of the project in the energy sector by means of technical and environmental indicators.

Results:

It was achieved the development of a laboratory-scale system producing hydrogen from the decomposition of water in a basic solution by using aluminium. It has been later optimized for its application in the pitol plant. At the same time, variables of the process have been studied, in particular the sample temperature and size, to obtain results on the kinetics of the reaction and evaluation of the performance under different experimental conditions. In addition, it has been carried out the quality control of the fuel both in the laboratory and in the pilot plant.

Moreover, it has been obtained an objective perspective of the developed process, which has given the possibility of knowing and interpreting the possible negative and positive consequences in relation to the environment and the economic-industrial sector. It is believed that the technology developed in this project will have its place in the sustainable energy sector at medium-long term. Thus, suggestions have been made to reduce pollutant emissions in the process of obtaining hydrogen to face a future phase of optimization of the pilot plant.

Finally, the technical and economic impact study on the developed procedure has given the following results:
• Low energy consumption during the reaction and the possibility of reusing certain reagents reintroducing them into the system.
• Considerable reduction of costs compared to other processes working under extreme conditions (high temperature and pressure) or requiring very specific reagents.
• The developed indicators help to identify the level of initial and current iversion of the project and the situation of the developed technology in the current energy market.

This project was led by the company JAP Energérticas y Medioambientales and participant entities were ITE and INGENIERÍA PARA EL DESARROLLO TECNOLÓGICO S.L. The project was co-funded by the Life Programme of the European Union (LIFE 11 ENV/ES/593).
