Coking coal<br />

Coking coal is a type of hard coal that can be used in the production of coke, which is capable<br />

of supporting a blast furnace charge.<br />

Condensates<br />

Condensates are liquid hydrocarbon mixtures recovered from associated or non-associated<br />

gas reservoirs. They are composed of C5 and higher carbon number hydrocarbons and<br />

normally have an API gravity between 50° and 85°.<br />

Conventional biofuels<br />

Conventional biofuels include well-established technologies that are producing biofuels<br />

on a commercial scale today. These biofuels are commonly referred to as first-generation<br />

and include sugar cane ethanol, starch-based ethanol, biodiesel, Fatty Acid Methyl Esther<br />

(FAME) and Straight Vegetable Oil (SVO). Typical feedstocks used in these mature processes<br />

include sugar cane and sugar beet, starch bearing grains, like corn and wheat, and oil crops,<br />

like canola and palm, and in some cases animal fats.<br />

Electricity generation<br />

Electricity generation is defined as the total amount of electricity generated by power only<br />

or combined heat and power plants including generation required for own use. This is also<br />

referred to as gross generation.<br />

Ethanol<br />

Although ethanol can be produced from a variety of fuels, in this book, ethanol refers to<br />

bio-ethanol only. Ethanol is produced from fermenting any biomass high in carbohydrates.<br />

Today, ethanol is made from starches and sugars, but second generation technologies will<br />

allow it to be made from cellulose and hemicellulose, the fibrous material that makes up the<br />

bulk of most plant matter.<br />

Gas<br />

Gas includes natural gas, both associated and non-associated with petroleum deposits, but<br />

excludes natural gas liquids.<br />

Gas-to-liquids<br />

Gas-to-liquids (GTL) refers to a process featuring reaction of methane with oxygen or steam<br />

to produce syngas (a mixture of hydrogen and carbon monoxide) followed by synthesis of<br />

liquid products (such as diesel and naphtha) from the syngas using Fischer-Tropsch catalytic<br />

synthesis. The process is similar to those used in coal-to-liquids or biomass-to-liquids.<br />
