Sustainable aviation fuel from biomass via gasification and Fischer-Tropsch synthesis - new book chapter now available

Global aviation growth is set to continue in the coming decades, and the most promising strategy for reducing greenhouse gas emissions from aviation is the use of sustainable aviation fuel (SAF).
The so-called biomass-to-liquid (BtL) process is considered the most promising of several process pathways for producing SAF. In this process, syngas is converted into long-chain hydrocarbons by Fischer-Tropsch synthesis (FTS). SAF produced by FTS is considered a drop-in fuel, which means that existing aircraft can run on SAF without technical modifications. In addition, the use of sustainable biomass residues shows a high potential for emission reduction.

In the newly published book chapter "Sustainable Aviation Fuel from Biomass via Gasification and Fischer-Tropsch Synthesis" from "Chemicals and Fuels from Biomass via Fischer-Tropsch Synthesis: A Route to Sustainability", the specific BtL-FT route to produce SAF is described. This consists of torrefaction of lignocellulosic biomass residues, oxygen-blown entrained flow gasification, gas processing, and FTS, and yields liquid hydrocarbon fuels with high selectivity for SAF for further upgrading. Modeling of different pathway configurations-including integration of materials and heat and variation of process parameters-shows the potential of the BtL-FT pathway to produce SAF efficiently in both the short and medium term.

GOLD project: TUM Horizon 2020 delegation visits Canadian partners and technical meeting in France

Within the framework of the EU Horizon 2020 project GOLD on phytoremediation of contaminated soils and sustainable biofuel production (, partners of the Chair of Energy Systems at TU München ( visited the Canadian project partners of the Université de Sherbrooke in Quebec (, In addition to the project-specific exchange on research questions of fuel production from contaminated biomasses, the meeting focused on the exchange of content on future research topics and the intensification of international cooperation, especially between Europe and Canada.

After a fruitful first year in the GOLD project, with successful pot trials and sowing of the energy crops selected in the project, a first technical meeting in person took place in Lille, France, at the invitation of the project partner JUNIA. In addition to the status updates of the individual GOLD partners on the optimization of selected high-yielding crops for phytoremediation purposes and the conversion processes to clean biofuels with low ILUC risks, the upcoming activities to optimize the value chain bridging the gap between phytoremediation and biofuels were also the topic of the meeting.

The highlight of the meeting was the visit to the former MetalEurope Nord smelting site in Pas-de-Calais, which after its closure had been one of the most polluted sites in Europe. As one of five sites in the EU and seven worldwide (, the use of energy crops to phytoremediate these contaminated soils is being studied there as part of the GOLD project.

TUM commissions large-scale heat source on the Campus Garching

TUM has successfully realized and commissioned an additional building block for their “Living Lab” on the Campus Garching. Tapping the district heating system of the university, which is powered by the university-owned power plant, heat can be extracted at temperatures of up to 150°C and with a maximum power of up to 2.5 MWth. The hot water heat can be used to test innovative technologies on site.

Together with the team of the technical operation and the chair of Energy Systems, the Clean Tech company Orcan Energy AG has successfully tested one of their efficiency PACKs based on Organic Rankine Cycle (ORC) technology with a power output of 200 kWel Organic Rankine Cycle (ORC). With this approach it has been possible to test innovative solutions and to pre-qualify them for series production. The TUM appreciates the trust and is very pleased about the successful collaboration of the three parties.

Beyond ORC technology the heat source could also be used for experimental investigations of absorption-based technologies and heat pumps.

Potential der hydrothermalen Geothermie zur Stromerzeugung in Deutschland

Der Energiemarkt in Deutschland steht spätestens seit dem Einleiten der Energiewende vor großen Veränderungen. Die Bundesregierung strebt einen deutlichen Anstieg erneuerbarer Energieerzeugung an. Im Gegensatz zu der volatilen Stromerzeugung von PV und Windkraft, steht mit der Geothermie eine potentiell verlässliche und regelbare Energiequelle zur Verfügung. Der mögliche Beitrag der hydrothermalen Geothermie wurde daher in einer Studie im Rahmen der Geothermie-Allianz Bayern untersucht. Ausgehend vom theoretischen Potential der hydrothermalen Wärmemenge im Untergrund wird mit Hilfe einer Analyse der Bestandskraftwerke das technische und das wirtschaftliche Potential der Technologie ermittelt.

Towards the next generation bioenergy concepts

On November 24th the official start of the Horizon 2020 project Biofficiency took place at the Technical University of Munich. The Biofficiency project shall pave the way to utilize low-grade biomasses for power and heat generation. In the next three years, the 11 partners from Germany, Finland, Denmark, Belgium, Greece and the Netherlands will work towards developing the next generation of highly efficient, biomass-fired Combined Heat and Power (CHP) plants.

Heating and cooling are responsible for almost half of EU’s final energy demand. Replacing fossil fuels in e.g. heating, with sustainable biomass, is seen as a way to cut Europe’s dependence on fossil fuels and to cut greenhouse gas emissions. It has been predicted that the role of bioenergy in the heat market in Europe could be increased from 11% in 2007 to about 25% by 2020. Combined Heat and Power (CHP) from biomass is one of the most efficient ways to reach this increase. The main challenge for achieving a broader use of biomass as fuel in CHP generation are ash-related problems. Corrosion of boiler materials, due to the difficult ash composition of biomass, limits significantly the use of biomasses in high-efficiency CHP plants.  

The project will take a holistic approach to address these problems: Topics ranging from widening of biomass-feedstock through pre-treatment, utilization of different firing technologies in lab-, pilot- and full-scale development of future ash utilization possibilities to overall plant design will be investigated. “I feel confident that Biofficiency will have a big impact on future biomass use in power and heat generation.“ says Prof. Spliethoff, coordinator of the project and Head of the Chair of Energy Systems at Technical University of Munich.  

The Biofficiency project gathers a unique consortium of excellent academic facilities and industrial partners, providing an exceptional platform for successful execution of the project. By sharing collective experience, the partners aim to strengthen European bioenergy technologies and help solving global climate and energy challenges.  

Project partners are: Abo Akademi, DONG Energy, Energy research Centre of the Netherlands, Laborelec, Metsä Fibre, Mitsubishi Hitachi Power Systems Europe, National Technical University of Athens, Technical University of Denmark, Technical University of Munich, Valmet and VTT Technical Research Centre of Finland.
