Baltic Energy Innovation Centre has been engaged to finalize the public version of the final report.
On the 12th of December the final project board meeting took place in Gothenburg.
The project board meeting was chaired by Anna Svernlöv, head of department Production and Planning, Gothenburg Energy. The other participants were:
York Neubauer, Technical University of Berlin
Henrik Thunman, Chalmers University of Technology
Martin Seemann, Chalmers University of Technology
Jörgen Held, Renewable Energy Technology International AB
Ingemar Gunnarsson, Gothenburg Energy, BioProGReSs project leader
The final report was discussed. By combining expertise in several scientific and engineering disciplines together with unique experimental, pilot and demonstration facilities the close and collaborative effort has resulted in successful demonstration of two new innovative technologies; chemical looping reforming (CLR) and online tar measurements (CON-TAR).

There are societal benefits of renewable methane produced through gasification and methanation of biomass and waste, bioSNG, in all the steps of the value chain, i.e. production, distribution and utilization.
Production: BioSNG has the highest conversion efficiency, from feedstock to final product, of all second generation biofuels and hence provides a resource efficient way to convert indigenous feedstock to a high quality transport fuel.
Distribution: Since bioSNG is miscible with natural gas in any proportion it can be distributed in an efficient and environmentally friendly way through the existing natural gas grid. The bioSNG produced in the GoBiGas plant is injected into the high pressure grid in Gothenburg.
Utilization: The versatility and the low combustion emissions make bioSNG an attractive renewable fuel not only within the transportation sector but also for efficient heat and power production and in industrial processes where clean and efficient combustion is required.
Other societal benefits: The greenhouse gas emissions are significantly reduced when bioSNG replace fossil fuels and for countries like Sweden with vast biomass resources the bioSNG route offers several other benefits such as increased security of supply, regional development and new job opportunities.
European Biomass Conference & Exhibition takes place 12-15 June in Stockholm. In a side event called Bioenergy – from Research to Market Deployment in a European Context the BioProGReSs project will be presented by the project coordinator, Ingemar Gunnarsson, Gothenburg Energy.
Online tar measurements as means to control the gasification process
Tar and tar related problems continue to remain the foremost obstacles in the development and implementation of gasification technologies into today‘s energy supply systems. Aromatic and polycyclic aromatic hydrocarbons (PAH) are by-products in most high temperature thermochemical conversion processes. They lower the efficiency of these processes and form tarry deposits when the gases are cooled and vapours begin to condense. It would be desirable to have a tool that is not only capable of monitoring the PAH composition and load of the product gas of a gasifier but is also sufficiently fast to be used for process control to minimize the formation of PAHs in the reactor. Up to now, no easy-to-use and reliable tool with a sufficiently low dead time has been available for tar monitoring.
LED technology for industrial applications
The new online tar measurement technique developed by Technische Universität Berlin is based on Light Emitting Diodes (LED) for Fluorescence Spectroscopy. The basic principle behind the measurement technique is simple. The light from the LED is used to excite different species in the hot product gas coming out of the gasifier. By detecting the emitted light from the analytes (tar forming aromatic species in the gas) with a spectrometer, information about the total amount and some information about the molecular size distribution can be obtained. Light emitting diodes have several advantages over lasers when it comes to industrial applications. Besides being more stable and reliable especially in a rough environment they are also much cheaper. It is possible to combine multiple diodes with different wavelengths in an array to take advantage of the diverse absorption-emission behaviour of different PAHs.
A technical breakthrough
The new and innovative online tar measurement technique was installed and tested in the 20 MWbioSNG GoBiGas plant in Gothenburg at the end of 2016. At this stage it’s possible to measure changes in the level of the detected tars and also if there is a shift towards heavier or lighter tars during operation. Ingemar Gunnarsson, Development engineer at Gothenburg Energy and no friend of big words stated that “It looks very promising” regarding the industrial use. In fact it’s a technical breakthrough that has potential to revolutionize monitoring and control of biomass gasification processes worldwide.

On the 19th of May the first BioProGReSs project board meeting took place at Gothenburg Energy with Prof. York Neubauer, TU Berlin connected online.
The role of the advisory board is to monitor the project, ensure that the project follows the schedule, keeps the budget and delivers result according to the plan. The advisory board takes strategic decisions regarding the project in order to optimize the outcome and success of the project.
The project board is chaired by Anna Svernlöv, head of department Production and Planning, Gothenburg Energy. The other project board members are:
Frank Behrendt, TU Berlin
Jörgen Held, Renewtec AB
Per Lindeberg, Gothenburg Energy
Henrik Thunman, Chalmers
The status of the project and the different workpages were presented by Ingemar Gunnarsson, Daniel Nyberg and Malin Hedenskog, Gothenburg Energy, Martin Seemann, Chalmers, York Neubauer, TU Berlin and Jörgen Held, Renewtec AB.
The project board approved the progress report to the Swedish Energy Agency covering 2014 and the first quarter of 2015 as well as the draft communication plan.
On the 16th of February BioProGReSs had its first consortia meeting at Chalmers University of Technology. The different project partners presented themselves and the work packages was discussed. After a full day of interesting discussions the GoBiGas plant was visited.

On the 18th of September the BioProGReSs kick-off meeting took place at Chalmers University of Technology in Gothenburg. The first tar measuring campaign using a novel measuring technique developed at TU Berlin will be conducted in the Chalmers 2 MW bioSNG plant in the beginning of 2015.
