The Energy research Centre of the Netherlands (ECN) has developed a novel technology for the methanation of gas from biomass gasification. The ECN System for MEthanation (ESME) is especially designed for gas from fluidized bed gasifiers such as Bubbling Fluidized Beds, Circulating Fluidized Beds and allothermal gasifiers such as the ECN MILENA process or the FICFB process developed by the Technical University of Vienna. In October 2014 a duration test of 500 hours has been successfully performed with 3 kW producer gas generated in the ECN MILENA gasifier and cleaned in the OLGA tar removal system. The gas composition after the methanation section is at chemical equilibrium. Little or no reduction in catalytic activity has been observed after 500 hours of operation under realistic conditions. This milestone paves the way for the scale-up of bioSNG production. In particular, a consortium formed by ECN and a number of partners intends to build a 300 m3/h (~3 MW) SNG pilot-scale facility.
