MHIs Post Combustion Carbon Dioxide

Recovery Process & Status Update

2/23


BackgroundBackgroundCoal looks certain to remain the principal fossil fuel forPower Generation in the foreseeable future

Clean coal technology development is great but what aboutthe existing plants? CO2 capture retrofit ability is critical

MHI offers a post-combustion solution a commerciallyproven, high performance CO2 capture process with

construction of 4 CO2 capture plants in the past 5 years

CO2 capture does have a penalty but also has a possibility

of a side revenue stream CO2 sales for EOR now &emission trading later

Large coal-fired flue gas CO2 recovery plants have not been

constructed before, However all the necessary equipment

specific to these plants have been commercially proven, in

other industries, in both their size and service and are notunique.

In Sum m aryn Sum m ary Coal has a number of advantages distinguishing it fromother fuels (price, abundant & stable supply)

It will take a suite of technologies to make a differencebut MHIs post combustion CO2 capture process is availablefor both retrofit and green field and, most importantly, is

commercially proven

Governments must continue to play an important role inthe promotion of large scale CCS demonstration projects by

incentivizing industry investment

Large scale demonstration is a stepping stone to our CO2

problem MHI offers a phased, logical roadmap leading tocommercialization for coal-fired boilers
