This microgeneration of power is seen by energy companies as far more efficient than creating power in power stations and transmitting it to households across the UK. The practicalities of such energy production are only coming to light at present due to technological advances which mean fuel cells are more user-friendly than they have been in the past.

It is hoped in the future that, through this method of generating power, the fuel cells in every home will produce enough energy to begin sending some back through the national grid for redistribution, therefore making the energy market more efficient. (fuelcelltoday.com)
