Biomass Conversion / Retrofitting a Dutch Power Plant

Reduce Emissions with Biomass (Co-)Firing

RWE continuously improves the CO2 footprint of its power plants across Europe, while simultaneously keeping efficiency up. One way to achieve such an improvement is through retrofitting coal power plants to co-fire biomass wood pellets.

Assigned by RWE Generation NL, RWETI is responsible for Biomass Conversion of the 631MW Amer 9 Power Station in Geertruidenberg, The Netherlands. It will be able to achieve a biomass ratio of 80% when the project is finished by RWETI in end-2019. This effort will reduce CO2 emissions by 2.400.000 ton. RWETI role in the project encompasses supporting the project development and  complete project management, associated interfaces from start of the execution including construction supervision and commissioning to take over.

The main challenges of co-firing are related to the properties of different fuel types combusted and to optimize this in relation to the existing power plant design, particularly the calorific value, moisture content, ash production and combustion characteristics. As such, various technologies perform differently depending on the biomass type and the quantities co-fired. 

Our combustion experts are highly experienced in the different combustion and fuel switching technologies, additional equipment, storage and transport needs as well as the associated investment and operating costs.
