Siemens and E. ON Collaborate On Technology Concept

Posted on March 1, 2010

Siemens and E.ON have announced they will jointly investigate concepts for the utilization of coal in gas turbine power plants. The objective of this cooperation is to evaluate these concepts both from the operator’s and supplier’s standpoint.

The pre-combustion carbon capture technology used is based on the conversion of coal to combustible gas. The syngas produced can be utilized for power generation in specially developed gas turbines in integrated gasification combined cycle (IGCC) or gasification combined cycle (GCC) power plants.

Alternatively, it is also possible to convert the syngas by means of methanation to synthetic natural gas (SNG). This has the advantage that the SNG can be used in existing and new standard combined cycle power plants also featuring the newly developed SGT5-8000H gas turbine without any modifications.

This technology is based on coal gasification using a gasifier developed by Siemens Fuel Gasification Technologies. The carbon dioxide can be removed from the syngas using a physical process with a high separation rate. Besides coal, other fuels such as biomass and refinery residues can also be used.
