Deep conversion
of solid fuel

We turn coal from an energy resource into valuable chemical feedstock: turnkey coal-chemical complexes and the revamping of existing coal-fired plants with chemical conversion cycles.

HSS integrates gasification, hydrogenation, catalytic and deep fractional processing in a single cycle — without the Fischer–Tropsch process.

Traditional coal chemistry versus HSS

The industry today runs coking, gasification (Lurgi, Shell SCGP, GE/Texaco, Siemens GSP), direct (DCL) and indirect (ICL) liquefaction — usually as separate plants. HSS integrates their advantages into one complex.
