Great idea and great concept. We were looking into this for our activities as well (biomass-to-energy projects). One example is BFS, a spanish company doing this on a large scale (http://news.algaeworld.org/2016/08/the-story-behind-a-multi-million-algae-biofuel-project-in-spain/) but unfortunately they went bankrupt recently. Nevertheless I find it a very interesting case to study!
Thanks, Oluwamayowa. The problem we still face with aluminium is the local availability, the price and the sustainable sourcing. It would be interesting to share more ideas and info! Our email address is email@example.com, it will be transferred to me and we can exchange directly!
