Comparison beetween different fuels

Comparison of energy type:

Energy: cst of 100kWh PCI in €
	1998	1999	2000	2001	2002	2003	2004	2005	2006
Gas	1,22	1,16	1,72	1,96	1,67	1,85	1,81	2,34	2,98
Electricity	5,34	5,23	5,11	5,10	5,14	5,21	5,28	5,28	5,36
Heavy Oil	0,98	1,17	1,91	1,72	1,8	1,84	1,69	2,36	2,75
Coal	0,78	0,79	0,79	0,94	0,85	0,76	0,95
Petroleum coke									1,3

Pet coke

Petcoke is 2 to 3 time cheaper than Gas

Emissions of CO² for different kind of energy:

	Energy/ T	CO²
	Gj/T	kgCO²/GJPCI
Coal	26	95
Pet Coke	32	96
Wood	18,2	92
Heavy Oil	40	78
Natural Gas	49,6	57
GPL	46	54

Petcoke, coal, wood use to exhaust 1,7 more CO² than Gas

=,22 kg CO2 per kg fired clay (gas) will become 0,37 kg CO² per kg fired clay (solid energy)

if we go on an additional cost of 100€/T CO² announced in 2008 it will mean an over price of 15€/T fired product due to the emission of CO²

That’s mean that the gain for using Pet Coke instead of Gas could be not more than 10% to 20% on the energy cost of a plant.

Additional question actually the pet coke prices still be low because of increase of the production (+50%) due to poor quality of crude oil and improvements in oil refining technology but many refineries plan to use this excess of pet coke in local power plants. This will probably increase the sale price of Pet coke in the future (however is high content in SO² will maintain it price bellow coal price)

The Petcoke is usually an economic alternative in countries where the gas price is higher than 1,5 €/ 100kWh PCI and there is no cost for additional emission of CO² (USA China, South America, India,…)

Other concern is SO²
