The results from the LignoSys project has been published in the European Biogas Association Newsletter.
The European Biogas Association has published a news related to the results of the LignoSys project.
LignoSys was featured in the Biogas Syd Newsletter (in Swedish) on the 29th of January 2019.
The LignoSys final report has been published as Renewtec Report 008:2018.
The most striking result is that small scale bioSNG technology based on allothermal gasification is able to compete with large scale bioSNG technology based on pressurised, oxygen-blown gasification not only in terms of GHG emissions, primary energy need and conversion efficiency but also in terms of bioSNG production cost!
The Danish Gas Technology Centre (DGC) has acquired a lab scale Heatpipe Reformer. Within the LignoSys project DGC will gasify pelletized straw and the results will serve as an input for the system studies performed by Lund University.
On the 23rd of July the project coordinator visited DGC where a measurement campaign on pelletized straw took place.

WoodRoll® is one of three thermochemical conversion routes that is investigated within the LignoSys project. The technology is based on drying, pyrolysis and indirect gasification of biomass and waste.
The WoodRoll® system is developed and marketed by Cortus Energy AB.
The first industrial scale facility was inaugurated on the 19th of June at the premises of Höganäs AB, the world leading manufacturer of metal powders.

Jörgen Held presented the LignoSys project at the Swedish Energy Agency Programme Conference, 29-30 November, 2017 in Eskilstuna.
The participant list included 50+ researchers presenting their projects within the Biofuels Programme. Projects related to both bio- and thermochemical conversion routes were presented.
Several presentations were related to bioSNG (biomethane through gasification and methanation) and it’s evident that the interest for biomethane is increasing. The high conversion efficiency, the low emissions and the cost competitiveness compared to other second generation biofuels are factors in favour of bioSNG.
To produce biomethane through bio- or thermochemical conversion of biomass/waste the carbon dioxide formed during the conversion process has to be removed.
Within LignoSys, upgrading by chemical absorbtion was selected as the preferred option since excess process heat is available for the thermochemical conversion routes.
Puregas Solutions a supplier of biogas upgrading based on amine scrubbing took part in a project meeting in November 2016. As a result of the meeting Puregas Solutions has provided the complete interface list based on the WoodRoll® gasification system.
On the 9th of November, Prof. Thomas Kienberger, Head of Chair, Energy Network Technology, Department of Environmental and Energy Process Engineering, Montanuniversität Leoben visited Environmental and Energy Systems Studies at Lund Institute of Technology within the framework of the LignoSys project.
During the meeting, data for the Heatpipe Reformer technology, which is one of the conversion technologies included in LignoSys, was discussed on a detailed level.

The integration of an amine scrubber for CO2 removal with the WoodRoll® system was discussed in a meeting on the 14th of October at Lund University.

The WoodRoll® process produces a clean syngas that after methanation consists of roughly 50% methane and 50% carbon dioxide. The carbon dioxide has to be removed in order to achieve biomethane of vehicle fuel quality. Nice features of the thermochemical conversion path are the absence of hydogen sulfide since sulphur is removed upstream of the methanation reactor, and that the methanation process provides sufficient heat for regeneration of the scrubber liquid.
