GE TECHNICAL / ECONOMIC FEASIBILITY STUDY

• GE completed a study that answered the two main

questions that customers were asking:

– Will the 6, 7 and 9 series gas turbines burn WPC syngas?

– Can GE confirm that the gas turbine will not experience a

de-rate when operating on a blend or a full load of WPC

syngas?

• GE confirmed that WPC syngas is suitable for the 6, 7

and 9 series units, and that in each case operating on

syngas will create additional power when compared

to fossil fuels.

Syngas study assumptions

• Two options: − Blending syngas and natural gas

− 100% Westinghouse Plasma syngas

• Calculations performed on a delta basis − Baseline performance on new and clean gas turbine

configured to operate on natural gas with a Dry Low

NOx (DLN) combustion system

• Fuel composition:− 45.5% CO, 22.4% H2, 16.4% CO2, 10.3% N2, 1.63%

CH4, 1.28% Ar, plus 1.64% higher hydrocarbons and

small amounts of NH3, H2S and COS.

• Ambient conditions:− 1.0 atm, 15 °C and 60% relative humidity, and 0 meters

altitude

Notes:

(1) New and clean delta performance should be similar to delta for gas turbine unit that has

been in operation on natural gas for some period prior to the switch to blended fuel.

(2) Switch to blended fuel may require fuel nozzles to be optimized to new fuel based on

revised fuel composition and heating value.


Option 1: blended syngas and natural gas

• Blend limited by CO and/or H2 content to stay within DLN

combustion system limits

• Plant configuration impact:

- Fuel blending generally requires a blending skid, gas measuring

instruments, and new gas turbine controls.

• Output (MW): +1.0%

• Heat rate (kJ/kWhr): - 0.38%

• Exhaust Energy (GJ/hr): +0.48%

• Output (MW): +1.23%



Assuming that blend stays within limits and DLN combustion system is

retained.

9F.03

• Output (MW): +0.74%

• Heat rate (kJ/kWhr): -0.19 %



Option 2: 100% syngas

• Use of 100% syngas generally requires switching from DLN to a diffusion

combustion system. Therefore, the fuel is not limited by CO and/or H2

content.

• Converting to 100% syngas fuel generally requires new controls, syngas

and diluent modules, as well as changes to other BOP systems.

support 100% syngas operation


• GE is a world leader in generating power from low

calorific value fuels, including syngas, with more

than 2.1 million operating hours

• GE gas turbines are capable of operating on a

variety of types of syngas, including the

Westinghouse Plasma syngas

GAS TURBINE REFUELING MARKETS AND TARGETS

Currently, there are over 5,000 6, 7, and 9

series GE gas turbines operating globally

that are a potential target for fuel

replacement

Who benefits:Users: Importers of high cost fuels

Sellers: Countries that export high value fuels. E.g.

Middle East countries use fossil fuel to generate

highly subsidized power

Environment: Lower CO2 footprint, reduced landfill

WHY IS TEES VALLEY #1 SIGNIFICANT FOR THE REFUELING OF GAS

TURBINES?

The operation of the Tees Valley #1 project will demonstrate:

1. Commercial volumes of syngas:

• 1000 tpd of feedstock will produce ~3.5 Million GJ/year of syngas

(50 MW electrical)

• Base load production of energy

2. Syngas that is consistently produced at the required specification:

• To ensure reliability, the syngas must consistently meet the fuel

specification of the gas turbine

3. Ability to create low cost syngas from feedstock's that you get paid to

process:

• A moderate tipping fee generates enough revenue to cover the operating

costs to make clean syngas
