This study was conducted to estimate the potential for producing
hydrogen from key renewable resources (onshore wind, solar photovoltaic,
and biomass) by county in the United States and to create maps that
allow the reader to easily visualize the results. To accomplish this
objective, the authors analyzed renewable resource data both
statistically and graphically utilizing a state-of-the-art Geographic
Information System (GIS), a computer-based information system used to
create and visualize geographic information.
Land-use and environmental exclusions were applied to represent the most
viable resources across the country. While wind, solar, and biomass are
considered major renewable resources, other renewable energy resources
could also be used for hydrogen production, thus contributing to
hydrogen development locally and regionally. These additional resources
include offshore wind, concentrating solar power, geothermal,
hydropower, photoelectrochemical, and photobiological resources.
This study found that approximately 1 billion metric tons of hydrogen
could be produced annually from wind, solar, and biomass resources in
the United States. The greatest potential for producing hydrogen from
these key renewable resources is in the Great Plains region. In
addition, this research suggests that renewable hydrogen has the
potential to displace gasoline consumption in most states if and when a
number of technical and scientific barriers can be overcome.
