Iceland’s Deep Drilling Geothermal Energy Project

 

by Shannon O’Neill

Iceland’s unique geology has made it a prime region for the development of geothermal energy. Specifically, the Reykjane Peninsula, located on the Mid-Atlantic Ridge on the southwestern coast and the home of four volcanoes, is a prime region for such development. Its volcanic geology provides geothermal pools that are heated by the steam and magma deep below the service. Geothermal wells harvest the heat from the pools to power turbines, providing one hundred megawatts of power, enough to power thousands of homes in the region. Iceland is powered almost solely on renewable energy resources, with geothermal energy contributing to a fourth of such resources. Continue reading

Iceland’s Turning Greenhouse Gases Into Stone

by Hannah Brown

Positioned near the Hellisheidi Power Plant in Iceland, researchers at CarbFix, a $10 million project funded by Reykjavic Energy, the United States Department of Energy, and the EU, among others, combines water and carbon dioxide, compressed to the point that is in its liquid form, and injects the mixture thousands of feet down into balsatic rock, a reactive volcanic rock that makes up almost the entirety of Iceland’s foundation, as well as the Mid-Atlantic Ridge in general. The combination of carbon dioxide and water interacts with the rock as it releases calcium and magnesium and turns into the original mixture into limestone. Initially the model predicted that the process would take 5 years but CarbFix has found that it happens much faster than expected, essentially completing the transformation of carbon dioxide into limestone within one year.
