We're still waiting on the official word, but late yesterday The New
York Times reported that the Idaho
National Engineering and Environmental Laboratory and
Ceramatec, Inc. plan to reveal a
breakthrough in hydrogen production research today.
According to sources in the article, the lab uses water heated to
1,800 degrees Fahrenheit and a ceramic sieve from Ceramatec along with
electrical current, and yields the "highest-known production rate of
hydrogen by high-temperature electrolysis."
That means the method uses less energy to produce hydrogen The most
common means of producing hydrogen today is electrolysis, running
electricity through water to split it into its components: hydrogen and
oxygen. Using coal, the most common source of electricity in the US
today, consumes around four times the more energy as the resulting
hydrogen can produce.
The new method would have "about half the energy value of the energy
put into the process," a vast improvement.
That's good news for the hydrogen economy proposed by the Energy
Department, and for hydrogen powered fuel cells
At least if the system ever gets implemented. According to the New
York Times, the new hydrogen production scheme would require the
building of new types of nuclear reactors. Nuclear reactors haven't been
built in the US for years.
