• Efficiency• Cost of the CCS• Captures upwards of 90% CO2
• Lower cost• Flexible output
• High reliability • Lower environmental footprint• Scaleable
Key advantages of IGFC power plants
The next step in the CCS revolution…
…transforming coal from the dirtiest fossil fuel to the cleanest
B9 Coal present the next step in the CCS clean energy revolution
employing a unique Integrated Gasification Fuel Cell (IGFC) process
Addressing both the rising cost of energy and the need to reduce global CO2 emissions it
combines the gasification of coal with the use of hydrogen to generate electricity with fuel cells

Depleted Gas/Oil Field
Saline Aquifer
Pipeline Transport• Compressed CO2 is transported in a dense, liquid like phase• Better economically and environmentally than shipping • Large-scale transportation of CO2 in pipelines has taken place for over 30 years in the US • Case Study: Snøhvit project, North Sea Came on stream in 2007, transports 700,000 tonnes CO2 per year for 145km from a liquid
natural gas facility to the Snøhvit oil and gas field
Saline Aquifers• Aquifers are sandstone formations that hold saline water• CO2 is pumped into the sandstone, filling the pore spaces• Largest capacity storage options• Case Study: The Sleipner Project, North Sea
250km off coast of Norway, around 1 million tonnes CO2 removed from the Sleipner West Gas Field per annum and injected into aquifer 800m below seabed
Depleted gas fields Sandstone formations that held natural gas The shale cap which once prevented the gas from escaping now holds in the CO2
Potential field location and geology already well known Reduced costs - number of existing pipelines and rigs could be used Confidence - millions of tonnes of gas and oil already stored securely UK well suited - close to North Sea gas fields
Captured carbon dioxide is compressed, transported and stored in geological structures to prevent its escape into the atmosphere
Carbon Transport and Storage
Compression• Compressed to reduce volume• Compressed to dense phase >90bar
Ship Transport• Trucks or ships are suitable for transportation of
small volumes or over long distances• CO2 is liquefied for ship transport• Shipping of liquefied CO2 similar to shipping
liquefied petroleum gases (LPG)

B9 Coal present…
…a game-changing clean energy proposition
Clean Potential for upwards of 90% carbon capture
Green Small footprint power plants: no turbines or other heavy infrastructure; AFC Energy’s fuel cells are made from lightweight recyclable materials and cartridges are refurbishable
Efficient Alkaline fuel cells are the most efficient way of converting hydrogen to electricity; carbon capture as part of the process with no loss of efficiency
Low cost Minimal infrastructure means low capital costs; AFC Energy’s fuel cells are cheap to manufacture; low running costs as fuel cell maintenance is simple
Small footprint No turbines, minimal infrastructure
Fully scalable Modular nature of the fuel cells means capacity can be increased to meet demand
Load following Modular fuel cell system allows output to be increased or decreased with no loss in efficiency
Reliable Alkaline Fuel Cells are 99.999% reliable as they are a solid state technology

B9 Projects in action…
Project plan • Powerfuel is constructing a large scale IGCC power station with carbon capture capability at Hatfield site• Initial construction will involve 800 MW combined cycle gas turbine (CCGT) facility optimised for 'syngas' conversion
and operation• Powerfuel to convert CCGT plant into 900 MW IGCC power station fuelled by extensive coal resources at Hatfield
colliery• The syngas can be used to produce hydrogen as a feedstock for 330 MW of alkaline fuel cells power generationConfid

B9 Coal…
…the future of clean energy
B9 Coal’s low cost, flexible, clean energy
proposition will revolutionise the way we
produce electricity, providing an essential step
in the move to a low carbon future and acting
as a global template for clean energy
generation.
