Oel-Waerme-Institut GmbH | An Institut der RWTH Aachen

Welcome to the Oel-Waerme-Institut

OWI provides research services investigating and developing concepts and new technologies for heat and power generation on a basis of fossil and renewable fuels. It aims at developing energy-efficient and environmentally friendly products which are marketable. At the same time, OWI cooperates closely with industrial partners and research institutes and sees itself as an mediator between fundamental and applied research. OWI is a non-profit organisation and an acknowledged institute affiliated to RWTH Aachen University.


Diesel and water are used to generate „clean“ power –
Milestone in the fuel cell-project „SchIBZ“

21st October 2016 – The OWI reformer technology enables the transformation of diesel fuel and water to a fuel gas with high hydrogen content. Such reformers can be integrated into fuel cell systems which generate electricity. In an ongoing research project a reformer of the OWI shall transform diesel and water into hydrogen for the operation of a fuel cell system. The hence generated electricity can be used in the future for the energy supply aboard of seagoing ships in a highly efficient and environmentally friendly way. … More

Industrial furnaces can be operated more efficiently and economically –
Development of a FLOX-burner for liquid fuels

12th August 2016 – In a joint project the e-flox GmbH, the Institute of Combustion and Power Plant Technology (IFK) of the University of Stuttgart as well as the OWI Oel-Waerme-Institute develop a novel combustion approach for the use of different liquid and biogenic fuels by applying the FLOX-concept. The FLOX-concept is already successfully used in the gas firing technology for thermal process equipment. Within the FLOX concept a flameless oxidation or combustion of fuel takes place and hence the name of the concept. Industrial furnaces and firing systems driven by liquid fuels could be even more efficient, cost-effective and combined with low-emission by using the FLOX-concept. … More

Time and cost efficient development of grease –
Research on an innovative screening method

15th July 2016 – The development of greases is a technically complex and time consuming process. Typically, there are several iterative development cycles with repeated examinations necessary, which increases the cost with each cycle. Common release tests for the determination of the grease´s stability are expensive and time consuming. Simple and yet reliable stability tests do not exist so far. With the support of the German Society for Petroleum and Coal Science and Technology, the Oel-Waerme-Institut and the Kompetenzzentrum Tribologie at the University Mannheim are doing research in the field of screening method development. … More

Analysis of inner deposits at diesel injectors –
Development of a cost-effective screening-test

12th July 2016 – It is expected that inner deposits in diesel injectors occur much more frequently in the next years. This will lead to an increase of the number of injector malfunctions. Higher injection pressures (above 2.500 bar) in combination with high-precision components such as injectors, manufactured with smaller openings combined with high temperatures in the injectors, also affect the fuels. To examine the effects of inner deposit formations (Internal Diesel Injector Deposits, IDID) in a structured way, the Institute of Energy Process Engineering and Chemical Engineering of the TU Bergakademie Freiberg as well as the Oel-Waerme-Institute carry out a research project. … More

Investigation of Hydrotreated Vegetable Oil as fuel –
HVO passes first test procedures

10th May 2016 – Hydrotreated Vegetable Oil (HVO) is partially admixed to diesel fuel nowadays. The Institute for Energy Process Technology and Chemical Engineering (IEC) of the Technische Universität Bergakademie Freiberg and the OWI Oel-Waerme-Institute GmbH investigated within a joint research project, whether HVO represents a complement to the offer of conventional and biogenic fuels in the heating market. They concluded that from a technical point of view HVO is in principle suitable as an admixture to fuels such as low-sulfur heating oil for oil heating. … More

IGCS Winter School 2016 –
The sustainable production of liquid biofuels and their application

28th April 2016 – How can biodiesel be produced in efficient manner, environmentally friendly and cost-effectively? Which chemical-physical properties are relevant for the storage and stability of biodiesel? Which aspects of the sustainability in respect to the production and utilization of biodiesel need to pay a special attention? During the IGCS Winter School at the Indian Institute of Technology Madras (IIT Madras) in Chennai (February 22 – March 4, 2016), 30 students became familiar with these and other questions. The key issues were the production, characterization and utilization of liquid biofuels, particularly in relation to biodiesel as well as the related technological challenges and political aspects. … More
