Projectsin the Research Cluster

The projects presented below have been combined in the Future Fuels research cluster. They are divided into the two areas “Modern technologies and combustion concepts” and “Use of greenhouse gas-reduced fuels”. Project profiles with a short description and information on terms, research partners, funding sources and research budgets can be found by clicking on the links.

Modern technologies and combustion concepts

SchIBZ – SchiffsIntegration Brennstoffzelle:

Development of a SOFC fuel cell generator for use on sea-going ships. Special feature: The hydrogen is produced from diesel fuel. SchIBZ is a beacon project of the National Hydrogen and Fuel Cell Technology Organization. Development work began in 2011 and was successfully completed in 2016 with the commissioning of a prototype. In the follow-up projects SchIBZ 2 (since 2017) and Multi-SchIBZ (planned from 2018), work will continue. The aim is to operate the prototypes on board and to develop the components right up to industrial maturity.

Production of hydrogen from liquid and gaseous fuels (reforming):

This is an opportunity to use alternative and also very different new energy sources in existing efficiency technologies. During reforming, the fuels are broken down into the basic components hydrogen and carbon and the synthesis gas thus produced is fed into an energy conversion process, for example an internal combustion engine. The necessary processes and apparatuses (reformers) are developed in the research project “H2-Vario“. The focus here is on the use of liquid CO2-neutral energy sources. Two further projects are concerned with the use of waste heat from combustion exhaust gases from combined heat and power plants (CHPs) of small capacity by reforming processes. The aim is to increase the electrical efficiency of CHP units with biogas engines.

Use of diesel injectors with alternative fuels:
Method development and analysis

Injectors for diesel engines are highly complex components whose perfect function is a prerequisite for low-emission and efficient combustion. The IGF research project “ENIAK 2” – investigates the causes of internal deposits on diesel injectors. (link to project profile) For this purpose, a non-engine analysis method is being developed which could be introduced as a test criterion for the formation of deposits under various technical conditions in diesel fuel injection systems within the framework of the No-Harm requirement for fuel additives. The parallel FNR research project “SaveBio – Use of vegetable oil as fuel in agriculture” (link to project profile) focuses on the upgrading of agricultural machinery for multi-fuel use. Strategies are developed to avoid deposits on diesel injectors.

Use of fuels with regenerative components in modern heating technologies:

Biogenic fuels have a different ageing behaviour than conventional fossil fuels. To elucidate this phenomenon, investigations are carried out to avoid higher molecular aging products in middle distillates with biogenic components under application conditions. The work is supplemented by the development of a test method for evaluating the material resistance of components in middle distillate applications. It enables rapid tests for heating components under application-related conditions.
