Vitrifying nuclear waste for storage is complicated by aluminum and understanding this behavior is vital. Research suggests that upon radiolysis, the properties of humid aluminum particles do not change substantially but hydrogen is formed.
80 years after the Hindenburg disaster, it still influences perceptions about the use of hydrogen as a vehicle fuel, but hydrogen, like gasoline, can be handled and used safely.
PNNL is collaborating with three small businesses to address technical challenges concerning hydrogen for fuel cell cars, bio-coal and nanomaterial manufacturing.
Cleaning up Hanford is no easy task: it is one of the world's largest and most complex environmental remediation projects. The nation's top engineering firms are on the job and the Department of Energy's PNNL is helping.
Using a natural catalyst from bacteria for inspiration, researchers have now reported the fastest synthetic catalysts to date for hydrogen production-- producing 45 million hydrogen molecules per second.
