Updates from the Coordinator 

Three years of development and cooperation in FLEXCHX project!

The FLEXCHX project took off in March 2018 and now, the project has come to an end and will be finalized soon. In FLEXCHX, successful project work has been carried out despite globally challenging times. The particular mission of the project was to validate the key enabling technologies of the FLEXCHX process and we have succeeded excellently in the pursuit of this goal.

The test campaigns were very successful although the pandemic challenged the whole world – FLEXCHX managed well! Using exceptional arrangements, testing activities were possible to continue all the time in facilities, and the employees doing experimental work adapted well to the changes. The coronavirus crisis has shown the importance of cooperation between the scientific world and the rest of society, making the significance of applied science increasingly visible to society. The results carried out during this project – also analysed according to techno-economic and LCA – have marked a promising track to be run for the development of the next-generation technologies!

Finally, the meetings and the continuous cooperation with all the consortium partners have been rewarding and fruitful. And most importantly, the aim to reach and break the proposed targets have been fulfilled!

Validation of the key enabling technologies: One of the project’s main objective achieved!

The key enabling technologies of the FLEXCHX project were successfully validated at the 1 MW pilot gasifier of VTT Bioruukki in March 2020; despite the challenging situation dealing with coronavirus threat. Large-scale test campaigns could be implemented jointly with qualified personnel of VTT, Lithuanian Energy Institute and INERATEC, Germany.

The validation test for the complete gasification, gas cleaning, and FT-synthesis process were carried out. SXB-pilot plant was operated under gasification conditions continuously for 70 hours. The gasifier operation was satisfactory throughout the test, and there were no major process-related problems. The biomass residues were converted to Fischer-Tropsch wax and oil, which can be further refined to renewable transport fuels. Operation time with MOBSU-FT unit was roughly 61 hours.

EUBCE2019 - 27th  European Biomass Conference and Exhibition

The FLEXCHX project was presented at the 27th  European Biomass Conference and Exhibition (EUBCE 2019 Conference) on 27-30th May 2019 in Lisbon (Portugal) by oral presentations:

Successful FLEXCHX Workshop in Lithuania!

On April 3, 2019, FLEXCHX held a well-attended industrial thematic workshop “Highly Flexible Combined Heat, Power and Transport Fuel Production – Prospective Technology in our Energy Future” in Kaunas, Lithuania. The Workshop was organized by Lithuanian Energy Institute (LEI), VTT Technical Research Centre of Finland Ltd, Enerstena UAB and Kauno energija AB. The workshop was opened by director Dr. Sigitas Rimkevičius from LEI. The welcome speeches were given by Lithuanian Energy Minister Žygimantas Vaičiūnas and Member of the Seimas, Chair for Commission for Energy and Sustainable Development, Virgilijus Poderys. The workshop included presentations from project participants as well as from invited speakers representing industries, raw material supply chain, policy makers, environmental organisations and financing bodies.

FLEXCHX project would like to thank all workshop participants for their great interest and participation in the discussions.
