The Desert Research Institute (DRI) in Reno, Nevada is currently conducting an
experiment in using hydrogen to store energy from renewable resources like wind
and solar. Hydrogen has the potential to be a cost effective and versatile
method of storing and transporting energy. Hydrogen, for example, can be
stored over much longer periods than electricity in batteries. This project,
which is supported by the US-DOE, is a precursor to a larger project that DRI
hopes to install in Alaska in a few years.
The prototype system includes two Bergey 1.5 kW wind turbines on 100 ft
guyed-lattice towers, a small (~ 1.2 kW) solar array, an electrolyzer to produce
hydrogen, a hydrogen storage system, and a 4 kW fuel-cell to convert hydrogen
back into electricity. The system was installed over the summer of 1999
and commissioned in October 1999.
