v

Co Conversio ion of f fossil ssil fu fuelle led power plant flu flue gas as CO2 to Meth thanol

Why Meth thanol is is preferred?

• Methanol is used largely as feedstock for many chemicals,

Formaldehyde, acetic acid, polymers, paints, adhesives, construction materials.

• Methanol could become more readily available (Methanol

economy) as an alternate fuel

• Less CO, NOx, SOx, and VOC’s.
• Onboard Methanol Reformer emissions are less.
• Readily degraded through photo oxidation and

biodegradation.

• Degrades in almost all environments.
• No evidence of bioaccumulation.

Lower Emissions Lower Price per Calorie Safer Liquid Fuel Energy Efficiency, High Octane A solution for internal combustion engines Utilize existing infrastructure Creation of local employment opportunities

Methanol as a Alternative Fuel - Advantages

Processes involved in CO2 to Methanol Production CO2 extraction from flue gas H2 Manufacturing CO2 to methanol reactor

MefCO2 – Methanol Fuel From CO2

Sali alient features of

• f MefCO2
• Hydrogen production: Demonstration of flexible operation of water electrolysers can be

used to decrease energy costs of hydrogen production.

• Optimised power plant operation when coupled with flexible hydrogen production for

methanol production.

• CCU can help power plant to maintain its competiveness while reducing their emissions.
• Growth of cost competitive non- manageable renewable energy generation will spur a

new set of business opportunities.

• Methanol produced in MefCO2 is considered as an advanced fuel and its renewable

energy content can be double counted towards the Renewable energy content in transport.

• Moreover, direct blending of methanol with gasoline can reduce the imports of gasoline.

Carbon foot print reduction through utilization pathway for fossil fired power plant Technology:

• Energy efficient CO2 separation from Flue Gas of Fossil fired

power plant

• Conversion of captured CO2 to Methanol by catalytic

hydrogenation

Development, Design and Setup of Integrated Flue Gas Carbon Capture and Methanol (FG-CC-MeOH) Pilot Plant in NTPC Power Station

Thermal plant

Benefits:

• India‘s first power plant with carbon capture unit.
• World’s first methanol production plant based on

CO2 captured from flue gas of fossil fired plant.

• Potential revenue stream for power plants
• Making fossil fired power plant environment

friendly & thereby sustainable

Power Plant Electrolysis Methanol

Summary of the presentation

• Global Climate Change - A great threat to humanity
• India’s initiatives towards Global Climate Change - reduction of emission intensity to 33-

35 % by 2030

• NTPC’s share in All India Generation and Capacity- NTPC is India’s leading power major

having more than 52GW energy generation

• NTPC Energy Technology Research Alliance- It is a unique R&D facility which caters the

technical service needs of power sector

• Major sources of CO2 Emissions- ¼ th of CO2 emissions are released by power plants
• Methanol is preferred as Methanol is used largely as feedstock for many chemicals
• Methanol as a Fuel Alternative because of its Advantages
• In power plant scenario, Methanol can be produced by the catalytic hydrogenation of

CO2 captured from flue gas

• CCU can help power plant to maintain its competiveness while reducing their emissions
• MefCO2 results could contribute to the reduction of the dependency on methanol imports
