The SmaRTGas Baltic project

On the 30th of October the SmaRTGas Baltic seminar took place in Malmö, Sweden. The seminar was financed by the Swedish Institute and arranged by Renewtec AB, Sweden in close collaboration with Tallinn Technical University, Lithuanian Energy Institute and Institute of Power Engineering, Poland.

SmaRTGas stands for Small Scale Renewable Methane Technologies based on Gasification and is focused on thermochemical conversion of biomass and waste to biomethane in the ~10 MW scale.

International experts and technology providers highlighted the ongoing technology development while representatives from Estonia, Lithuania, Poland and the European Biogas Association presented the market situation in the Baltic area and in Europe.

Biomethane through thermochemical conversion of woody biomass and waste offers many opportunities of relevance for the Baltic Sea Region since it transfers indigenous low quality resources including wastes into a renewable high quality transport fuel with superior emission data. Biomethane can be produced with the highest conversion efficiency of all second generation biofuels and distributed in an environmentally friendly way through the natural gas grid. Replacing diesel and petrol with biomethane has many advantages such as positive effects on the air quality, the greenhouse gas mitigation, the security of supply, regional development and new job opportunities.

Renewtec member of EBA Scientific Advisory Council

The European Biogas Association (EBA) Scientific Advisory Council is a network of researchers, scientists and university teachers dedicated to the promotion of biogas and biomethane.

In 2015 Renewable Energy Technology International AB (Renewtec AB) became a member of the Scientific Advisory Council.

European Biogas Association advocates both anaerobic digestion and thermal gasification and is the voice of biomethane in Europe. For more info take part of EBA´s Vision and mission.



Renewtec presented bioSNG activities including SmaRTGas in Brussels

On the 3rd of September Jörgen Held was invited to give a presentation on “The present status and future prospects of biomethane production through biomass gasification” at the European Biogas Association’s workshop on biomethane in Brussels.

The SmaRTGas initiative was presented as way forward to accelerate the technology transfer and the implementation of efficient second generation fuel production.

EUBCE, Europe’s largest biomass conference

The 1-4 of June 23rd European Biomass Conference & Exhibition, EUBCE 2015, took place in Vienna, Austria.

In total 1394 people from 76 countries participated in the conference. Notable was the huge interest for biogas, biomethane and gasification but it’s no surprise since gaseous biofuels have several advantages over solid and liquid biofuels.

Renewtec acted as session chairman for the session “Thermochemical Conversion Processes – Industrial Approach” and represented the European Biogas Association in the  the conference closing cermony.


According to Dr Held, we should not speak about biomethane from AD, biomethane from gasification or from any other technology separately, but about biomethane from renewable resources as a whole, which is a chance for Europe to increase energy security, have cleaner environment and stimulate growth. AD and gasification play together in one team as complimentary technologies.”

New Renewtec report on “Small scale gasification” (in Swedish)

BioMil and Renewtec have together conducted the project “Small scale gasification” (in Swedish). Within the framework of the project the biomethane production cost based on gasification and methanation of woody biomass has been calculated for two plants with a capacity of 5.6 MWth and 33 MWth and with and without district heating integration.

The study shows a production cost in the range of 6.40-12.20 SEK/Nm3 biomethane (approx. 70-130 eurocent) depending on the investment support of the Swedish Energy Agency, choice of interest rate, fuel cost and if the excess heat can be utilized or not. Additional cost reduction is possible if the separated carbon dioxide can be used, e.g. as carbon dioxide enrichment in greenhouses.

The project has been financed by  Region Skåne, Region Halland, AB Gas & Värmeteknik, AGA Gas AB, BioMil AB, DGC, E.ON Gasification Development AB, Highterm Research AB, Lunds Universitet, NSR AB, O2 Bio AB, Purac Puregas AB och Renewtec AB.

Renewtec wishes A Happy New Year

On the last day of the year Renewtec would like to take the opportunity to thank all clients, co-financiers and project partners for the good collaboration.

2013 has been an exciting year considering the increasing interest in biogas and gasification of biomass and waste, the result of the “Fossil fuel free transportation sector 2030” investigation and the market development of gaseous and liquid biomethane. Who could guess that issues related to cross border trading of biomethane would be in the focus already this year?

2013 was also the year when GoBiGas started up. Having followed GoBiGas on a close range since 2005 it’s pleasing to note that the brave and forward-looking investment by Gothenburg Energy now is realized.

2014 is prone to be at least as interesting and eventful as 2013. Don’t miss out the opportunity to meet world leading biogas and gasification experts at REGATEC 2014, 22-23 May in Sweden. There the first experieces of the commission and operation of GoBiGas will be presented. A few months later it’s time for the biggest biogas event in the Nordic countries, NBC 2014, 27-29 August in Reykjavik, Iceland. If everything goes as planned a decision to build a demonstration plant for biomethane through gasification and methanation in Scania, the southernmost province in Sweden, may be taken.

Happy New Year,

Jörgen Held

Swedish experiences of biomethane as vehicle fuel

On the 10th of December Jörgen Held was invited to present “Challenges and pitfalls faced in the Swedish development of biomethane as transportation fuel” at the Gasum Gas Fund Seminar in Helsinki. Almost 70 people from industry and academia participated.

The seminar was opened by the CEO of Gasum, Antero Jännes, who spoke about the plans to connect Finland and the Baltic states through a pipeline and the erection of a large LNG terminal. Among the other speakers one may mention prof. Peter Lund, Aalto University  who gave an exciting presentation on how the energy system has changed over time ” World Energy Transitions” and prof. Christian Breyer, LUT who presented a 100% renewable energy system based on solar energy in combination with renewable methane.

Visit at PSI and agnion

Jörgen Held, Renewtec AB visited Paul Scherrer Institute (PSI) in Switzerland and agnion’s pilot plant in Pfaffenhofen an der Ilm in Germany on the 29th and 30th of October.

PSI has developed a fluidised bed methanation reactor suitable for production of biomethane in the smaller scale (<100 MWth). The reactor has been tested at the gasification plant in Güssing within the European project Bio-SNG where the whole value chain from Wood chips to biomethane as vechile fuel was demonstrated. Commerical partner is CTU.

agnion has developed and commercialised a small scale gasifier suitable for biomethane production. In the pilot plant in Pfaffenhofen an der Ilm has catalytic tar reforming been tested.

Renewtec AB, in collaboration with BioMil AB, conducts 4 case studies on small scale biomethane production based on PSI’s and agnion’s technology.


Research engineer, Marco Senger, agnion (to the right) has just showed the pilot plant to Jörgen Held, Renewtec AB. In the background the catalytic tar reforming can be seen. Tests with automatic addition of active catalyst and removal of deactivated catalyst during operation have been conducted.
