The first stage isthe coal gasification process as mentioned above. The second stage takes the cleaned gasand burns it in a conventional gas turbine to produce electrical energy, andthe hot exhaust gasis recovered and used to boil water, creating steam for a steam turbine which also produces electrical energy. In typical plants, about 65% ofthe electrical energy is produced by the gas turbin
of chemical energy to electrical energy is more efficient and generates much less pollutions than do traditional methods that rely on combustion.
FuelCell Functionality
Fuelcells generate electricity from a simple electrochemical reaction in which an oxidizer, typically oxygen from air, and a fuel, typically hydrogen, combine toform a product, which is water forthe typical fuelcell.
Global Trend towards Protecting the Ozone Layer
Global Convention and Protocol
The Vienna Convention (forthe Protection ofthe Ozone Layer)
The Vienna Convention is a treaty concerning the customary international law on treaties between states. It codifies some groundwork of international law trying to protect the ozone layer. The US wasthe one the biggest producers and consumers of

supercapacitors have a lot in common with batteries, but we can say that they are the newest form of battery.
You can charge it in a very short period of time and repeat a number of charge and discharge periods.
