I notice that Hydrogen cells are the most popular vote for which type of energy we should develop. This is unfortunate as it shows that people do not understand the concept. Hydrogen cells only help the environment if the energy used to produce the hydrogen in the first place is from a renewable, non fossil fuel source.

For example, one way to get hydrogen is to electrolyse sea water using electricity. If the electricity used is provided by a solar panel or other renewable, fine. But if it comes from the National Grid, using fossil fuels, then we are no better off.

Your hydrogen fuel celled car will not pollute the city where you are driving, but a remote power station somewhere will be belching out just that little but extra carbon di-oxide.
