[RenewableEnergyAccess.com] Hydrogen Solar Ltd. has been named 2005 Scientific American 50 Business Leader of the year by Scientific American magazine for its contributions to the commercial development of carbon-free hydrogen-generating technology using solar energy. The technology, which has the capacity to address significant existing hydrogen markets and a future hydrogen economy, is a self-contained Tandem Cell that directly splits water molecules into high-purity hydrogen and oxygen using the energy from sunlight. The process is renewable, produces no carbon dioxide or other emissions and does not require any electricity. By using a modular design, the array can be built to an infinite variety of sizes, making it suitable for a wide range of industrial and energy applications.
