Weizmann Institute produces hydrogen using solar energy
31 August 2005The Weizmann Institute of Science in Rechovot has developed a process where zinc oxide is heated by solar energy until it splits into oxygen and gaseous zinc. The gas is condensed to powder. When reacted with water it produces hydrogen and zinc oxide which is recycled back to zinc.
The process generates no pollution, and the [...]
Purdue researchers use rhenium based catalyst to produce hydrogen
31 August 2005Researchers at Purdue have used a rhenium based catalyst to produce hydrogen gas from water. Costs associated with the process are still high but high volume production could make the process economically feasible.
We have discovered a catalyst that can produce ready quantities of hydrogen without the need for extreme cold temperatures or high pressures, which [...]
Porphyrin nanotubes for hydrogen production
18 March 2005Sandia National Laboratories has produced porphyrin nanotubes which could eventually be used for splitting water to produce hydrogen.
This investigation is exciting because it promises to provide fundamental scientific breakthroughs in chemical synthesis, self-assembly, electron and energy transfer processes, and photocatalysis. Controlling these processes is necessary to build nanodevices for efficient water splitting, potentially enabling a [...]
DOE “Clean Coal” award
17 March 2005The Department of Energy has awarded $62.4 million to develop a coal fired zero emissions powerplant.
Among the objectives of the research are:
* Improved and new methods of producing pure hydrogen in coal gasification;
* Hydrogen handling — safe storage of hydrogen, and on-board storage which will aid [...]
Safer catalyst for hydrogen production
17 March 2005Ohio State engineers have developed an environmentally safer catalyst for producing hydrogen which is approximately 25 percent better than current options.
Though the new catalyst is still in the early stages of testing, it could represent an important step toward using the nation’s coal supply to power alternative fuel vehicles and equipment.
