Power-to-Fuels – Decarbonizing the Mobility Sector

Fuel OptionsBusiness drivers/objectivesMethanol as a base chemical to:• Blend with fossil fuel• DME and MTBE as an add-in to fuels• Methanol-to-Gasoline process• Synthesis of hydrocarbon chains as the future

fuel

• Green Methanol market with huge potential and the option to displace Bio-Ethanol

• Green Methanol market price expected increase to 800–1000 $/t near-term driven by RED-II and other regulation

• Contributes to the EU’s objectives of decreasing CO2 emissions through carbon neutral fuels

Description• Lowest levelized cost of electricity and high load

factors from wind and partly solar• Hydrogen production at large scale and

competitive with fossil generation cost• Export Green Methanol to Europe

Future of Energy in Europe is about Decarbonization through Sector Coupling and a new Market Design

Sector Coupling: Leveraging renewables in power sector to decarbonize heat, mobility, industry

Decarbonization of Energy: Transforming the conventional generation capacity into low-carbon assets

Mobility: Need to reduce carbon footprint from mobility creating demand for hydrogen and green fuels

Power-to-X and Hydrogen: Key technology for sector coupling and fuel for decarbonization of energy

Regulatory Framework: Set decarbonization targets, technology-open, the end of the energy-only market

Cornerstones of a Future Energy System
