Let's not get carried away. A 1.5kW fuelcell running 24hr/day should always produce more electricity than a 0.5kW PV system working only in sunshine. Likewise the claims about CO2 abated; adjust for the different size of the systems and the fuelcell still comes out as better by about 1.6times not the 5-6times factor CFU claims.
Very disappointing CFU has resorted to 'tabloid' reporting of results.
