32 MWth Indirect Gasifier→ 20 MWSNG
www.ieabioenergy.com6
Demonstrated on 20 MWSNG scale → 200 MWSNG scale
• Production costs estimated at 600 SEK/MWh~60€/MWh
• The gasifier ran ~12.000 hoursand several 1000 hours of gas tothe grid
• At 8000 hours of operation~500kton per year is needed
• Approx. 60.000 Nm3/h SNG couldbe produced

• Green Gas allows you to operate utilities in industry, households and in transport without modifications for end users.
• Green Gas has a good carbon footprint, with the proper selection of feedstocks
• Green Gas will produce a large stream of high quality CO2 in order toreach product specifications, allowing you to off-set carbon balances via sequestration
• Green Gas can be linked to the massive gas infrastructure, which lowersthe burden in shipping of feedstock/transport of end-product.
• Green Gas is a stepping stone to other high value outlets if theinfrastructural needs change over time. (fuels, hydrogen, chemistry)
Why is Green Gas a good idea?
www.ieabioenergy.com12
• Gasification is a technology mature enough to be implemented on large scale
• The resource base for gasification is large
• Grid connectivity is high
• The benefit of realizing negative emissions, via sequestrationpossibilities will become increasingly important.
Deployment of the technology is behind…. We need industry to start investing and governments to support this!
