Power providers E.On and Siemens are working together on a pilot CO2 capture plant at the hard-coal fired Staudinger Unit 5, near Hanau, Germany.

The facility, which will run on part of the flu gas from Unit 5, will run until the end of 2010 and serve as a large-scale demonstration plant for the technology.

Siemen’s said its post-combustion process can remove 90% of the CO2 from the flue gas using special cleaning agents, and that its process can be teamed with the further developed steam power plant process.

It will enter commission at about 2015.

Carbon capture projects are being trailed around the world as a way to overcome the increasing need to use fuels such as coal and natural gas – both major CO2 emitters.

Siemens Energy CEO of fossil power generation Michael Suess said carbon capture is increasingly being seen as the way forward for low-emission power generation but many technologies are still premature for use in today’s plants.

“These technologies are available but they have to be tested for deployment in large plants, developed further and brought to market readiness,” Suess said.

E’ON plans to have its first industrial-scale CO2 Capture and storage operation in 2020, E’ON chief technology officer Bernhard Fischer said.

“With the post-combustion process we are focusing on a highly promising CO2 capture technology, which can be retrofitted to existing power plants,” Fischer said.
