Now that the first trimester was finally over, it was time to kick back and relax for a few days. During our classes, we learned about cutting edge technologies, such as solar PV cells that can see 40% or greater efficiency, advanced hydrogen storage and fuel cell technologies, advanced Kalina cycle geothermal turbines, and 120 meter tall wind turbines. The purpose of the study tour is to ground what we learned in reality, so we can see what is the current state of the technologies that we learned about. While the study tour is not supposed to be as rigorous as regular classes, there is still a lot that can be learned from our visits. However, we did find the time to enjoy ourselves on our break between trimesters.
The facility, pictured above, requires a constant source of electricity greater than 600 MW, enough power for more than half a million people! The white alumina powder is shipped in from South America, processed, and the finished Aluminum ingots are shipped to their final destinations throughout the world.
The rationale for building the smelter and associated power in plant in Iceland takes more of a global perspective. Alternate sites for the smelter would likely be in less developed countries, and the power would be generated by fossil fuels, such as cheap coal in China. By siting the project in Iceland, overall global emissions from the aluminum production would be far less than if the same product were made in other countries.
Outside of Reykjavik, the group visited a few geothermal facilities, such as the Hellisheidi combined cycle power plant, the Svartsengi plant, as well as two geothermal well sites. These facilities, along with a few other plants in the area, supply the capital region with almost all of its electricity, hot water, and district heating needs.
One added bonus to the trip was a surprise visit to the Presidential compound, called Bessastaðir. The president, Ólafur Ragnar Grímsson, said a few words about the work that we were doing and allowed a few questions from our group. Afterward, we were allowed to tour the compound, which sits on ancient ruins dating back hundreds of years.
What was mentioned here were some of the things that we did during the week long study tour. Many other site visits, such as the Icelandic Innovation Center, the Sorpa landfill biogas recovery, the hydrogen fueling station, and others were not described here, but were certainly educational as well! By the end of the week, we had a few days to ourselves to rest and enjoy the city of Reykjavik and its infamous nightlife. Some took side trips to the Golden Circle, others went to museums, churches, or markets throughout the city. After the brief break, it was then time to head back to Akureyri for the start of classes once again.
