Project Development

EC FP6 call 2003.ML

Relevant subjects in the 2003.ML CfP

–R&D of cost efficient biofuel production systems from ligno-cellulosic biomass

– R&D & optimisation of energy-efficient, cost-effective technologies for producing of hydrogen-rich gas from biomass

CHRISGAS Summary

• System studies related to the large-scale use of and

its impact on the environment and society at large

and Training activities are included in this IP

•The hub of the Integrated Project (IP) is the existing, unique 18 MW biomass-fuelled pressurised air-blown gasification combined cycle CHP plant at Värnamo

• The Värnamo plant will be refurbished to

oxygen gasification to produce a hydrogen-rich gas.

• This IP offers already in 2007 gasification RD&D

at large scale at a lower cost than alternatives

CHRISGAS Objectives

To demonstrate the production ofa clean hydrogen-rich synthesis gas

(within a 5 year period at 18 MWth,3 500 Nm3/hr H2 equivalent)

based on:– steam/oxygen-blown gasification of biomass

– hot gas cleaning (to remove particulates)

– steam reforming (of tar and light hydrocarbons,

incl. CH4)

The VVBGC Plant, Värnamo

•Steam/oxygen blown gasification

•Hot gas filtration of raw gasification gas

•Reforming of tars and methane

•Water gas shift to hydrogen-rich gas

•Planning for further downstream rebuilds

Parallel R&D activities– Feedstock biomass logistics

– Biomass drying integration

– Pressurised fuel feeding (piston feeder)

– Gasification, hot synthesis gas characterisation (laboratory and bench-scale work)

– High temperature filtration/cleaning

– Catalytic steam reforming (decay & deactivation)

– Shift gas catalyst characterisation

Other activities

– Training (university courses and ”hands-on”)– Dissemination– Process studies (e.g. novel methods of

contaminants removal)– System studies (e.g. H2, methanol, DME, F-T)– Socio-economic impact

- emissions- jobs created- regional growth
