Project goal:

The main idea of AliCE-Why is to tackle aluminium (Al) recycling for clean energy production. Al demand is evermore increasing as well as energy production, but recycling possibilities are relatively scarce in small country or remote location context. In addition, transportation of current waste Al requires additional costs and does not generate jobs and revenue on unused resources that are exported. Thus, a local cyclic process for recycling should be developed. Main goal of this project is to develop technology and prototype for power generation form waste Al through production of hydrogen and further recycle by-product Al hydroxide.

Project summary:

Currently, waste management and energy production are recognized as essential field for world sustainability assurance. Aluminium (Al) is a very important strategic material in Europe with wide variety of application areas. Unfortunately, this invokes huge amount of waste Al generation. Despite that part of waste Al is recycled, there are plenty of landfilled Al, which pollutes environment. Therefore, during this project, we will initiate scientific and engineering activities revealing innovative ways for waste Al application on electricity generation using hydrogen produced after waste Al-water reaction.

Obtained reaction by-product can be further recycled back to Al via carbon free electrolysis. Also, by-product can be used as a precursor for other valuable materials production. All the mentioned processes will be realized as a prototype.

The project will involve: investigation of the waste Al treatment for hydrogen production (Lithuanian Energy Institute); analysis of generated hydrogen gas purity (Institute of Solid State Physics University of Latvia (ISSP)); recycling of produced reaction by-product to Al and/or other useful materials (Innovation Center Iceland); evaluation of techno-economic and environmental impact of proposed process on Iceland and Baltics (University of Iceland), prototype design (coordinated by Latvian team). The project Consortium consists of four partners with main tasks mentioned above, which will ensure close cooperation and successful project realization.
