CTL — Coal to Liquid

Turn domestic coal reserves into high-value, ultra-clean liquid fuels — diesel, methanol and hydrogen — through gasification and Fischer-Tropsch synthesis.

Diesel Methanol Hydrogen
The Challenge

Energy Security from Domestic Resources

Many coal-rich regions still import refined fuels at volatile prices. CTL converts abundant domestic coal into drop-in liquid fuels — capturing far more value at home instead of exporting raw coal and importing diesel.

The Process

Coal → Syngas → Clean Fuels

CTL is a mature, commercially proven pathway built on two core steps: gasification and Fischer-Tropsch synthesis.

1
Gasification

Coal is converted at high temperature with steam and oxygen into synthesis gas — a mixture of carbon monoxide and hydrogen.

2
Gas Cleaning & Conditioning

Syngas is cleaned of sulfur, particulates and contaminants, then conditioned to the ideal ratio for downstream synthesis.

3
Fischer-Tropsch Synthesis

Clean syngas is catalytically converted into ultra-clean diesel, methanol and hydrogen — fuels with near-zero sulfur and aromatics.

Key Benefits

Why Coal to Liquid

  • Ultra-clean diesel — near-zero sulfur and aromatics, a true drop-in fuel for existing engines and infrastructure
  • Energy security — convert domestic coal into fuels otherwise imported at volatile prices
  • Multiple products — diesel, methanol and hydrogen from a single integrated plant
  • Proven at scale — gasification and Fischer-Tropsch are commercially demonstrated worldwide
  • Value uplift — capture refining margins at home instead of exporting raw coal

What It Runs On

CTL plants are designed around the coal available at your site — from low-rank coal and lignite to bituminous grades — with gasifier selection matched to feedstock characteristics.

  • Mine-mouth deployment — build at the coal source to eliminate fuel transport costs
  • Flexible coal grades — including lower-value coals unsuitable for export
  • Co-processing options — biomass co-feed can lower the carbon intensity of the product slate
