PTX PROCESS
The PtX process relies on
the supply of a sustainable
carbon feedstock (biomass
or other unavoidable
industrial carbon dioxide
sources, or carbon
directly captured from
air) and the production
of green hydrogen
through electrolysis using
renewable energy.
The carbon and hydrogen are converted to synthesis gas, a mixture of carbon monoxide
and hydrogen, which in turn is converted to longer chain hydrocarbons for the production
of SAF or other fuels and chemicals via the FT process..

With decades of innovation and operational experience on our side, and strong
partnerships in the PtX field with Haldor-Topsøe (for syngas production and hydro
processing technology) and Technip Energies (licensor support engineer), ecoFT is
positioned well to be a leader in the nascent PtX sector.
ecoFT leverages Sasol’s world-leading Fischer-Tropsch (FT) technology to produce
low carbon sustainable fuels and chemicals via the Power-to-X (PtX) process
There are technologies other than PtX to produce SAF from renewable sources, such as
waste biomass or used oils. While these technologies are prevalent, supply is limited with
SAF making up less than 1% of total global jet fuel demand. Furthermore, a limit exists on
the amount of SAF that can be produced from biomass and oils given land availability
constraints, competing food priorities and water usage concerns. Emissions from these
processes are also not fully compatible with a net zero emissions future.
On the other hand, the PtX process is fully compatible with a net zero emissions future
as it allows for 100% CO2 emission reductions. Currently, it is a more costly technology
option relative to oil and biomass. However, these costs are expected to decrease rapidly
this decade on the back of technology advances and manufacturing commoditisation,
which will make the PtX process more cost competitive. Furthermore, it is not constrained
by feedstock limitations and can supply the significant global jet fuel projected demand of
~7 million barrels per day. SAF is therefore likely to be one of the first and most attractive
sustainable applications for PtX technology.
