The CURA publications library is currently being digitized by the University of Minnesota Digital Conservancy. When the project is complete, the entire CURA publications library will be online and fully searchable. Unfortunately, during this process we are not able to honor individual requests for publications . Additionally, we no longer have physical copies of publications to send out.

New publications are digitized daily and the publications catalog on the CURA website is not automatically updated with links to scanned copies, so please search the CURA collection at the Digital Conservancy for the publications you are looking for:

Hydrogen Generation Using Magnetite to Store Energy from Alternative Sources.

Halley, J. Woods, Andy Schofield, and Bjorn Berntson.

Demand for alternative energy sources arises from the need to reduce both carbon emissions that cause climate change and U.S. dependence on fossil fuels from foreign sources. The leading alternative energy sources, wind and solar, however, are intermittent; the wind does not always blow and the sun does not always shine. Thus, it is necessary to find ways to store the electrical energy obtained from these sources. A leading candidate for energy storage is hydrogen gas, which is typically generated by using electric current (in this case, provided by wind or solar generators) to split water molecules using a process called electrolysis. The stored hydrogen can then be used to power vehicles or regenerate electricity for use at times when the wind drops or sunlight is unavailable. One problem with this scenario is that state-of-the-art electrolysers are very inefficient. With the cooperation of the Minnesota Department of Commerce’s Office of Energy Security (since renamed the Division of Energy Resources) and with funding from a CURA Faculty Interactive Research Program grant, this project investigated a more efficient method for splitting water to generate hydrogen using magnetite, an abundant Minnesota resource contained in taconite, which has been mined on the Mesabi Iron Range for use in the steel industry for generations. Because wind energy is also abundant in Minnesota, there exists the possibility for a very effective economic synergy between these two resources.
