About UCG Association

UCGA is the representative body for the global Underground Coal Gasification

(UCG) industry and exists to provide impartial, unbiased information and training

on all aspects of UCG including Carbon Capture and Storage (CCS)

Our Aim - to see the safe deployment of UCG technology worldwide.

Our remit - to educate, encourage and inform of the opportunity that UCG offers

to a world in need of safe, secure, clean, affordable energy

We have established a community for energy professionals, academia and

research and created a scientific and technical base for industry. A wholly

independent non profit organisation, the Association works at an internationallevel engaging with industry, governments, regulators, energy associations,

academia, investors, bankers, environmental agencies and the public to raising

awareness through education and information of the many benefits UCG offers

as a low carbon energy source.

About Clean Coal Limited (CCL)

CCL is an industry leader in the burgeoning field of Underground Coal

Gasification (UCG)

CCL has an experienced team of recognised UCG experts and has

assembled a portfolio of UCG projects globally

CCL has in-house legal, accountancy and corporate finance expertise

CCL has regional teams based in the UK, US and China supplemented by anumber of consultants

Our Strategy

CCL has a substantial pipeline of geographically and risk diversified

projects

CCLs strategy is to create a premier project pipeline based on three key

principles: Coal resources that are highly suitable for UCG exploitation.

Ready market and distribution network for syngas

Clear CO2 solution

CriteriaMinimum

Acceptable Value

Maximum

Acceptable Value

Coal seam thickness >3m 300m 1500m

Coal rank Lignite Bituminous

Proximity to fault structures >200m depending on site conditions

Proximity to built up areas >500m

Proximity to mines (active and historic). >500m

Moisture content


10/28

Hydrogeology

Water is required because:

1.it is an important reactant

2.it maintains pressure in the reactor

But too much water may:

quench the reaction chamber

reduce product gas quality

reduce or stop syngas production

Enhance contaminant formation.


11/28

Uncontrolled Groundwater Infiltration

Two main settings

1. via natural permeability/ porosity of

surrounding strata and coal seam.

2. enhanced permeability caused by

subsidence.

Need to identify sites with:

thick aquitards above and below

cavity.

overburden with suitable geotechnical

properties (stiffness, yield strength) to

reduce deformation. minimum faults,

joints etc.

some water present in coal and/or

surrounding strata.


12/28

Groundwater Contamination

Known to be a risk:

2 UCG trials in the US resulted in groundwater contamination (out of >30).

Heavy metals, benzene and phenols released.

Expensive, long-term remediation project to repair aquifer.

Main Issues

Inappropriate site selection.

Incorrect operating parameters.


13/28

Site Selection

Select deep coals (>300m)

These maybe in regions of poor

quality groundwater :

Deep coal seams are more likely to

isolate contamination from sensitive

aquifers.

Select regions with minimal faults

Select sites away from sensitive

aquifers.

Select sites with good thick

aquitards surrounding cavity.


14/28

How the Swansea Bay Site Compares

Criteria StatusTarget seam >300m Seam >500m deep

Limited faults & fractures To be determined

Site away from any

sensitive aquifers

Large distance between

known sensitive aquifers*

Limited pathway to

receptors

No pathway to any

receptors

Thick aquitard surrounding

seamTo be confirmed

Surface Site Cleanup

UCG has limited surface footprint compared with

other technologies:

reduced plant size (e.g. no coal stock piles);

Site restoration will limited to

removing borehole completions

surface piping

surface plant

reduced landscape alteration;

reduced impact on environment;

No large amount of re-landscaping required

Results in a relatively low cost for site

restoration compared with other fossil fuel-

based energy technologies.

Summary and Conclusions

Cheap form of Energy

Security of Supply

Environmentally friendly Huge availability of unmineable Coal (including offshore)

leading to UCG as a major integral part of the world energy

mix

Short period of time to commercial operation Multi uses of syngas
