The Economic Case for Wind and Solar Energy in Africa

To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by Lawrence Berkeley National Laboratory has found that wind and solar can be economically and environmentally competitive options and can contribute significantly to the rising demand.

Jefferson Lab Accomplishes Critical Milestones Toward Completion of 12 GeV Upgrade

The Continuous Electron Beam Accelerator Facility (CEBAF) at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has achieved two major commissioning milestones and is now entering the final stretch of work to conclude its first major upgrade. Recently, the CEBAF accelerator delivered electron beams into two of its experimental halls, Halls B and C, at energies not possible before the upgrade for commissioning of the experimental equipment currently in each hall. Data were recorded in each hall, which were then confirmed to be of sufficient quality to allow for particle identification, a primary indicator of good detector operation.

(Winston-Salem, N.C. – September 27, 2012) – New research funded by the prestigious National Science Foundation CAREER Award will look at how to safely and efficiently store hydrogen – one of the key problems preventing hydrogen from being used as an alternative fuel.

Award recipient Timo Thonhauser of Wake Forest University said current storage methods, such as compressing hydrogen into tanks, are unwieldy, making the storage question the big bottleneck in turning hydrogen fuel cars into a reality.

“Simply pumping pure hydrogen into pressurized tanks in your car is inefficient and potentially dangerous,” he said. “But even if you could, you just cannot get enough of it into the tank – you’d drive for 50 miles, and then your car would stop. So we need to find a better way to store hydrogen, and that means identifying a material that can safely incorporate it into its structure.”

The NSF CAREER Award, given to the nation’s top junior faculty who demonstrate excellence as teacher-scholars, comes with a $426,572 grant. Thonhauser, an assistant professor of physics, will use this grant to determine whether any of the three substances – magnesium borohydride, ammonia borane, and alkanes – could be used to create a safe and efficient hydrogen storage solution.

Hydrogen has shown great promise as an alternative fuel. It is the most abundant element on the surface of Earth, and every nation has access to it. One pound of hydrogen has about three times as much energy as one pound of gasoline, and seven times as much energy as one pound of coal. But even better, when hydrogen combusts, the only byproduct is water.

“So, if hydrogen is so cool, why aren’t we using it? It’s because we don’t know how to store it in a practical way,” Thonhauser said. “There’s no question that fossil fuels are going to run out eventually. Plus, the combustion of fossil fuels creates a lot of problems for the environment. Research into alternative fuels is vital right now.”

The CAREER Award also requires scientists to develop outreach programs. Thonhauser will work with SciWorks, a science and environmental center in Winston-Salem, N.C., to build an interactive hydrogen fuel exhibition; he also will create a mentoring program at Wake Forest to help graduate and post-doctoral students improve research skills and begin their careers as scientists.
