UK: Renewable Energy world Article : Hydrogen The Last Word
In a recent article in Renewable Energy World, entitled ?Hydrogen, The Last Word? (March-April 2004), Dr Ulf Bossel appears to be precluding any debate, despite the fallacies inherent in his arguments. Dr Bossel?s illustration of the high efficiency of wind generated electricity obscures the first basic principle that the grid does not store electricity. The big sources of renewable energy, wind, solar, tidal or wave energy are all variable in supply and will be dependent on hydrogen storage to maintain an economic load factor. If supplies of renewable energy are not available, then back up from the national grid, which in the UK is only 35% efficient, will be required.

SwanTurbines tidal energy system
A team of researchers at Swansea University in Wales, UK, are developing a new renewable energy system, extracting electrical energy from flowing water. It is a tidal stream device, using a direct drive (no gearbox) highly efficient system.
