1/4 Underground Coal Gasification

This information sheet provides an overview of the Underground Coal Gasification (UCG) process.

What is gasification? Gasification is the conversion of coal to a gas (called synthesis gas or syngas) through a series of reactions involving heat, pressure,coal and water. Coal gasification is not new. It has been used since the 1800s to supply heating gas to cities and towns, generate electricity from gas turbine power stations, and to produce synthetic liquid fuels. Syngas can also be used for producing chemicals or other gases such as hydrogen, methane, ammonia, methanol and dimethyl ether.

2/4 UCG Explained

This information sheet provides a technical description of the Underground Coal Gasification (UCG) process, the key parameters involved, factors in site selection and the operational influences on gas quality.

UCG is the process of the gasification of coal in-situ to produce a synthesis gas (syngas). The operating life of a UCG operation can be broadly broken down into four steps.

1. Well Construction and Linkage
2. Ignition
3. Gas Production
4. Decommissioning

3/4 Modern Practices in UCG

Technological advances in the last few decades have increased the number and reliability of tools that can be used to predict, control and monitor UCG operations. This information sheet explores the techniques that are bringing UCG into the modern age of energy production.

Advances in modelling software and ready access to high powered computers have made modeling issues related to UCG much more accessible. The types of information that can be analysed online or collected in the field and analysed quickly in a laboratory have also significantly increased.

4/4 Syngas in the Modern Energy Mix

This information sheet describes the potential of syngas, the product of Underground Coal Gasification (UCG), to contribute to the future energy mix in a carbon constrained world.

Synthesis gas (syngas) is the product of UCG and a very versatile energy product. It is well suited as the feedstock for a range of different products, including electricity and transport fuel. Syngas is the favoured feedstock for the major developmental clean coal technologies.
