PRODUCING HYDROGEN FROM WASTE ALUMINIUM

0

The general objective of the H2ALRECYCLING project is to design and build a pilot plant to obtain hydrogen using a new process based on the reaction between aluminium and ammonium hydroxide obtained from other industrial processes with the aim of optimising its efficiency for powering a fuel cell.

Society is gradually starting to establish transition strategies towards a hydrogen-based economy and a model in which hydrogen becomes an energy vector that is produced and used alongside electricity. In this model, each region can produce as much hydrogen as it needs and use this gas to supply transport, industry and homes.
The LIFE Programme is the only financial instrument in the European Union dedicated to the promotion of innovative technologies regarding the environment. The H2ALRECYCLING project forms part of this Programme and is made up of a consortium involving three Valencia-based entities: JAP Energéticas Medioambientales S.L.; INDETEC, an engineering company for technological development, belonging to the Vento Group; and ITE, the Energy Technological Institute.
The primary objective of the H2ALRECYCLING project is the design and construction of a pilot plant to obtain hydrogen from industrial aluminium waste, using a process based on the reaction between aluminium and ammonium hydroxide. The hydrogen produced supplies a fuel cell that will generate energy to be used for a range of purposes.
More specifically, the execution of the project seeks to achieve the following scientific-technical objectives:
• Designing, building and optimising an integrated process for the production of hydrogen from waste aluminium.
• Supplying a 5 kW PEM fuel cell with the hydrogen produced to obtain electricity.
• Integrating the different technologies that comprise the hydrogen production and electrical energy generation process into a single system to validate a new integrated technology that makes use of industrial aluminium waste.
All these objectives form part of the design and construction of a pilot prototype with a production capacity of 4.8 m3/h of H2 that can either supply a fuel cell with a capacity of between 3 and 5 kW or be stored in a gas holder for its subsequent use.
