Coaches with hydrogen fuel cell powertrains for regional and long-distance passenger transport with energy optimized powertrains and cost optimized design

Acronym CoacHyfied
Funding European Commission Horzion 2020



In the CoacHyfied research project, fuel cell systems for use in long-distance coaches are to be developed and tested together with 15 project partners. To this end, two solutions are being developed in CoacHyfied to overcome challenges such as the small installation space or the low recuperation potential. Furthermore, in this particular use case, numerous auxiliary consumers such as cabin air conditioning must also be taken into account. The coaches will be used and tested in two different regions for a period of 2-3 years.

The Chair of Thermodynamics of Mobile Energy Conversion Systems (TME) is developing a predictive maintenance scheduling concept based on generic state indicators for different components of the fuel cell system developed within the research project. With the help of the maintenance scheduler the lifeteime of the fuel cell system is to be increased.

Take-Off: Sustainable aviation fuel from CO2

Acronym Take-Off

European Union´s Horizon 2020




The Take-Off project, funded by the Horizon 2020 EU program, will explore the development of a unique technology based on the conversion of CO2 and renewable hydrogen to Sustainable Aviation Fuel (SAF) via olefins as an intermediate. This technology route aims to deliver a highly innovative process that produces SAF at lower costs and higher energy efficiency compared to other power-to-liquid alternatives currently available. The Take-Off route consists of capturing CO2 from industrial flue gas or direct air capture which reacts with hydrogen produced by renewable electricity to create light olefins. These light olefins are subsequently chemically upgraded into SAF. All innovative steps upgrading CO2 will be demonstrated under industrially relevant conditions.

SAF produced through the Take-Off technology could significantly support the aviation industry in reducing its carbon footprint and replace the utilization of crude jet fuel products while proving:

  • +70 % Carbon and hydrogen efficiency
  • -100 % Sulphur emissions
  • -20 % Total emissions compared to fossil aviation fuels
  • -36 % SAF production costs

The project will also quantify the economic and environmental performance of SAF produced from CO2 and renewable H2 via the light olefins route and competing production routes including:

  • Economic evaluation and identified opportunities for the reduction of fuel costs.
  • Environmental assessment and identify opportunities for the reduction of environmental impacts of jet fuel.
  • Optimization of the production of the SAF of the future by using cost and environmental performance data.

The overall aim of the conducted research at TME (RWTH Aachen) is to evaluate the emissions potential of the developed fuel candidates in comparison to commercial fossil based jet fuel and selected reference fuel components. One of the main objectives is to identify functional molecular structures responsible for NOx and soot emissions as input for an optimized fuel composition. Therefore experimental and numerical investigations are carried out to additionally quantify the potential of NOx and soot emission savings of SAF produced by the Take-Off project.

The achievement of the project objectives will contribute directly to the UN Sustainable Development Goals, European Green Deal, and the Renewable Energy Directive II, where sustainable aviation fuels are receiving increased attention.

Development of efficient and environmentally friendly LONG distance poweRtrain for heavy dUty trucks aNd coaches

Funding European Commission, Horizon 2020, Grant Agreement No. 876972

H2020 LC-GV04-2019


In the heavy-duty long haulage transport sector, the reduction of real driving emissions, fuel consumption and its related CO2 emissions are the main societal challenge. The LONGRUN project will contribute to lower the impacts by developing different engines, drivelines and demonstrator vehicles with over 10% energy savings (Tank to Wheel) and related CO2 reduction, 30% lower exhaust emission and 50% peak thermal efficiency. A second major achievement will be the multiscale simulation framework to support the design and development of efficient powertrains, including hybrids for both long haulage trucks and coaches. All developments, innovations and implementations will be assessed by 22 use cases reflecting all major topics for improvements to contribute to the overall project objectives.

The LONGRUN consortium represents a unique mix of industry-leading expertise and knowledge. The consortium consists of 30 partners from 13 countries and includes world key players in the heavy-duty powertrain and vehicle manufacturing sectors. These constitute the industrial core of the LONGRUN project. Profound experience in all aspects of the research is provided by major European research centers and universities. The consortium has access to and owns experimental and simulation facilities for testing and validation.

The LONGRUN OEMs will develop eight demonstrators in total (three engines, one hybrid driveline, two long-distance coaches and three long haulage trucks); within them technical sub-systems and components will be demonstrated, including electro-hybrid drives, optimised ICEs and after-treatment systems for alternative and renewable fuels, electric motors, smart auxiliaries, on-board energy recuperation and storage devices as well as power electronics. They will include concepts for connected and digitalised fleet management, predictive maintenance and operation in relation to electrification where appropriate, in order to maximise the emissions reduction potential. Altogether, these project outcomes will accelerate the transition from fossil-based fuels to alternative and renewable fuels and to a strong reduction of fossil-based CO2 and air pollutant emissions in Europe.
