The 7th conference was held in Reykjavik 25-27th April 2017 and turned out to be yet another successful event. A total of 93 delegates from 16 countries took part, with 46 from Iceland and 47 from abroad. A total of 20 presentations were given. The conference programme can be found here.
The keynote presentation was given by Prof. Halvor Kvande who discussed the carbon footprint of aluminium smelters and how it can be minimized. Analysing the CO2-equivalent emission at all stages in the production process he concluded that if all aluminium smelters used renewable energy sources, the CO2-eq emission could be reduced by 70%. Inert anodes have been discussed for decades and it has been assumed that implementation of such anodes would result in a major reduction in the carbon footprint. Halvor Kvande showed however that with the current energy mix, a switch to inert anodes would reduce the carbon footprint by 20%.
After the final session on day two, delegates visited the Century Aluminum Nordural smelter at Grundartangi. On day three, delegates visited the RioTinto Iceland smelter at Straumsvik. These visits were really interesting and allowed delegates to discuss technical matters on-site with professionals running the smelters.
The 8th conference is planned for May 2020. Copies of the proceedings are available from Innovation Center Iceland at $500 (contact Birgir Jóhannesson: email@example.com). The papers will then be sent by email.
Keynote presentation 2017:
How to minimize the carbon footprint of aluminium smelters
Dr. Halvor Kvande got his PhD degree in 1972 from the Norwegian University of Science and Technology (NTNU) in Trondheim, and in 1979 he defended his thesis for the Norwegian degree of Doctor Technicae from the same university.
From 1980 he worked in the aluminium industry in Hydro in Norway. From 1990 to 2005 and from 2011 to 2014 he also worked part-time as Adjunct Professor at his Alma Mater University in Trondheim. From 2009 to 2011 he was Professor and Qatalum Chair in Department of Chemical Engineering at Qatar University in Doha, Qatar. In 2012 he retired from his position as Chief Engineer at Hydro in Oslo, Norway.
His major field of interest has been research and development on the Hall-Héroult process for primary production of aluminium. Halvor Kvande is the author and co-author of more than 150 scientific and technical papers, as well as 5 books on aluminium electrolysis and related topics. His research work has been appraised in the form of several TMS awards and honours, and this also includes his contribution (as a member of the IPCC) to the 2007 Nobel Peace Prize.
